True Wireless (TWS) Earphones

Tin Hifi T3 Buds

The Tin T3 Buds were sent to me by Linsoul for me to share my opinions and publish this review. They have not made any specific requests and therefore, as usual, I will be as unbiased and honest as possible.

You can find a (non-affiliate) link to the T3 Buds via Linsoul by visiting the version of this review published on my blog (link at the end of this review).


I don’t think anyone can deny that Bluetooth has come a long way recently and that it is going to continue to improve, becoming the main audio solution for the general public. Yes, there are still going to be the audiophiles who focus on improving things and getting performance that only cables can bring (at this moment in time), along with those who simply prefer cables (me being one of them), but the majority of people will be more than happy to opt for bluetooth solutions.

It’s also true that IEMs have come a long way in recent times, getting better by the day (or so it seems) at prices that are getting cheaper and cheaper. That is bringing us to start seeing wireless IEMs in the “middle ranges” from companies who have focused mainly on wired options until now. By “middle ranges”, I am not referring to prices, it is more in reference to products from companies that are quite a step above the usual no-name TWS options on Amazon but way below some of the higher end (and more known) options like Apple, Samsung, etc.

Tin Hifi are one of those companies, bringing in the T3 Buds at a price of just under 90€. As Tin Hifi have had some good success with some of their wired IEMs (and some not so good), it is interesting to see what they can offer in this TWS world.


The box that the T3 Buds arrive in is fairly simple, just a black box (although the box does have a nice finish to it) inside a white sleeve with the brand and model on the exterior.

Inside the box we get the TWS IEMs inside their charging case, 4 sets of silicone tips, a USB to USB-C charging cable and the user manual/documentation.

That is the extent of the contents but except for maybe a few more kinds of tips, not much else that can really be asked for.

Build and aesthetics…

The charging case is round and rather compact, although I do find that the shape makes it a little more uncomfortable to carry than the oval or rectangular models from other companies. It is a very nice looking case though, in a dark metallic blue finish with a nice texture to the outside.

It may just be me but I did find it was a little more difficult to get them out of the case than with other models but that also means that they sit well in their charging ports, avoiding them moving and not charging correctly (something that I have experienced with other TWS IEMs).

The Buds are very similar to the T3+ in looks and shape, although these are slightly smaller with a little change to the ergonomics. They feel the same in the ears, except for the lack of cable over the ear of course, which means that I do find them comfortable. They are obviously a little heavier than the T3+, which is to be expected as they have the electronics inside them, but are not overly heavy and I find they can be worn for longer periods without fatigue.

Overall I like the aesthetics of the T3 Buds, as I did the T3+, giving them a bit of a premium look. They also seem to be well built, although that is something that will need more time to confirm.


The functionality is similar to many other models, using a combination of short or longer presses on the faceplate of the IEM.

A single press on either of the IEMs is for play/pause, a double press is for next/last track (right side for next and vice versa) and a triple press summons the assistant. To raise or lower the volume, it is a long press on the right (up) or left (down) but not too long, as too long will turn the Buds off.

While I applaud the fact that volume can be controlled from the IEMs, something that many brands miss and I feel should be obligatory, the choice of a long press to do so isn’t the best option. It makes changing volume a rather long task, especially if you want to raise or lower by more than a step or two, at which point it is quicker to just grab the phone.

I also find that the response to the touches is not great, taking various attempts on occasions for them to recognize the press. It could just be the fact that I haven’t got the hang of it but it did get a little irritating at times.

The connectivity is decent, letting me roam around my office or home with the phone on my desk, so no complaints there. They also connect very quickly, both on first connection and when reconnecting.

Audio from the mic is not the greatest but it is decent enough for short calls. I wouldn’t recommend them (or, to be honest, any TWS that I have tried) for conference calls and regular online meetings etc.


I had already been listening to the T3 Buds for a while before I saw someone post a graph of the frequency response. When I saw the graph, I was surprised as it looked far more exaggerated than what I was listening to. I measured it myself and got the same results, which still look far more exaggerated than what I hear personally.

Here is the graph in comparison to my personal preference target:

While on the subject of graphs, let’s get isolation out of the way also. As you may already know, you can view any of my isolation (or FR) measurements and compare them by following the link at the end of the review. Here is the graph of the T3 Buds isolation in comparison to zero isolation (grey dotted line):

Ok, now let’s get on with my subjective opinions on the sound, which do sort of resemble the graph but at a reduced level.

Starting at the lowest frequencies, down in the subbass area, the performance of the T3 Buds is actually fairly decent. It may not give the rumble that more subbass focused sets give but there is enough for these frequencies to be appreciated and not suffer from a large amount of roll off. I found myself enjoying music with plenty of content in the lowest of lows, without really feeling too much was missing, and while “Chameleon” may not vibrate the inside of your head, it does still sound full in the subbass areas.

In the midbass, there is a little extra presence there, giving some warmth to the low end of instruments such as guitars and basses, yet it is not too overdone. I would say that the extra presence of the midbass is about too much as subbass is too little. Noticeable but not terrible, making a lot of music enjoyable, especially things like classic rock that benefit from that extra bit of warmth.

In the midrange, there is a bit of a scoop going on that can make certain vocals seem to be missing a bit of presence in their lower to mid ranges. I find that vocals like Dua Lipa in “Don’t Start Now” seem to lose a little fullness in the lower vocal ranges yet they are still very present due to the boosted higher end of the mids.

In fact, the higher end of the mids is the point that my ear most disagrees with the graph of these IEMs. I said above that the graph seems to be more exaggerated than what I actually here and these ranges are exactly what I am referring to. Yes there is a little bit too much in the higher mids, which brings vocals forwards but at the same time can make the sound a little thin, especially in the case of acapella or vocal centric tracks, such as “I Concentrate on You”.

However, although the extra bit of “thinness” is noticeable when coming from other sets, it is not something that really jumps out too much and I found that my ears adjusted to it pretty quickly. Luckily this extra boost does fall away before hitting the 5kHz mark, meaning that I can tolerate it much better, but of you are someone who is sensitive to the 3 or 4kHz range, then this will probably be much more of an issue for you.

The higher frequencies do seem to extend fairly well, without any exaggerated roll off in these ranges, giving a nice touch of air and clarity. I can’t say they are amazing up at the top but I do find them to be similar to the regular T3 Plus in these areas, with sibilance being kept in check fairly well, only appearing on tracks that already have a large sibilance presence in the recording.

Details I also find to be similar to the T3 Plus, in other words, they are not the strong point of the T3 Buds yet there are enough to enjoy music without getting the feeling that things are missing. You certainly aren’t going to get suprised by details you have never heard before but you won’t have to search for things you have heard a thousand times either.

Soundstage I find to be decent, as is image placement, maybe not groundbreaking but enough to get a good sensation of openness and feel that the music is not just on a single plane.


There is one major issue with the T3 Buds that I haven’t mentioned yet but is something that needs to be considered. I was going to mention it under functionality, then under sound, but I guess late is better than never.

The issue I am referring to is the background noise of these IEMs. There is a background hiss that is quite prominent on the T3 Buds and is very noticeable both in silent parts and on quieter passages of songs. It is not the worst background hiss I have heard on a TWS but it is something that is very apparent.

In addition to that, there is the isolation, which is not great in general but even worse in the lower ranges. I would say that the main use for TWS IEMs is while out and about, due to the commodity of not having a cable, yet the lack of isolation in the lower ranges can make it difficult to appreciate the deeper notes, putting more emphasis on that boosted high mid range.

In general the tuning is ok, far better than I think it looks on paper, but those two issues do take away from the overall user sensation in my opinion. If you are mostly listening to busy music, in other words, songs that don’t have quieter passages or silent parts, then these are probably not going to be as apparent to you or be much of an issue.

My impressions of these earbuds! Enjoy, and have a great weekend, friends.


This is a reply to @MRHifiReviews
And 16 days out, not a single recommendation

OK, this gets very tempting. I have some lower end TWS - Hifiman TWS600 and the IE Fits which are sort of nice.

Like you I’m heavily invested in the Apple ecosystem. Unlike you, I don’t work out and it shows. So my use case is different. Maybe mowing the lawn (electric mower). I’ve not been impressed with any ANC - so far if I want to shut out the world, it’s the wired Etymotic ER4XR with double flange ouch tips.

And if I don’t have to shut out the world, I’ve got the cable in between style Audeze LCDi3 and i4

But I think that for calls - when I’m not using the Koss Porta-Pros, maybe mabye…
What do you ALL reccomend?

  1. Apple Airpod Pro gen 2
  2. Senn Momemtum TWS 3
  3. None of these, you don’t need it, you’re already spoiled.
  4. What about the Campfire Orbit TWS? Maybe not, no ANC.

Someone please tell me what to do. My better half is away and I’m lacking instruction.

If you are in the Apple ecosystem…I begrudgingly admit that Airpods have a serious edge. My Gen 1 is seamless and syncs between notebook, phone, tablet, and watch. I use them in situations where I’d previously switch between random little speakers and IEMs. Overall, I get better average and continuing sound quality than in the past. Elegant.

They also have the best noise canceling tech that I’ve ever owned – they tackle random sounds far above and beyond the airplane rumbles of old school Bose or Sony systems. “I see your lips moving but I don’t hear anything you say.” :face_with_spiral_eyes:

Sadly, the sound quality is roughly equal to my cheapy cheapy Sony Extra Bass, and their comfort is inferior. I don’t think micro Bluetooth amps have much potential, so there are tradeoffs per use case.

Yes, increasingly in the Apple ecosystem. Although I have an old Windows high end laptop also, I’m slowly transitioning from it to the MacBook Pro running Parallels when I really need Windows. My wife has a windows laptop, but lives on her iPhone.

I’ve toyed with picking up a Samsung tablet when the next release of Android is out, but that’s just toying. I tend to repurpose old machines to some version of Linux before they finally get thrown out. Even used ChromeOS for that.

But I have an iPhone, and an iPad Air 1st Gen (obsolete, but useful as a ROON endpoint) an iPad Pro 12 1st Gen (mostly retired, but nice screen), and a smaller M1 iPad Pro used mostly at work, and which is generally streaming for my speakers. So yeah, I’m just a bit too into the Apple Ecosytem.

It seemed from some of the reviews that the Senn Momentum’s are fairly closed to the AirPods.

APP2 for the reasons generic mentioned, especially the noise cancellation capabilities. It does wonders when cutting the lawn (non-electric rider mower here).

If you watched the video I created, I actually bought the Momentum TW3 and highly enjoy them for what it’s worth. I am also creating some video content on some over-ear true wireless headphones too that might be helpful. Apple seems to have the best ANC but not necessarily the best sound signature, at least for my preferences, but they are pretty good overall; however, we will likely see a new model next year for over ears, so I would either wait for that or look at another brand if you want to grab something now. Sorry for the delayed response. I missed this notification.

Thanks, Marcello. I did want to know if you still liked them, and if they were still fitting in well with the Apple ecosystem. The video is what piqued my interest. Not sure I’ll bite, but I feel like the fish that’s making the bobber jiggle just a bit.

So I lost my Jabra 75t about 3 months ago and was shocked to see that the Wirecutter now has Beats Fit Pro as their best of class, over the Air Pods Pro 2. Now I have laughed at Beats at being obnoxiously overpriced low end headphones for as long as they’ve been around, but I got a pair and… as far as I know they are the king of the hill. All the benefits of the Apple M1 chip so if you’re in that ecosystem it’s a no brainer. Sounds like the same noise reduction as the Airpods which is now ahead of Sony and Bose. The case does not feel rock solid and is bigger than my Jabras were. I also got some Comply tips which I like more than the silicone they come with.

I can’t believe I’m saying this either but I like the fixed spatial audio, it seems like the sound stage is wider and better positioned to me.


Oh, the only other thing I wasn’t happy with: two weeks after I bought them they came out with some options that are skin toned.

My skin is milky white with red splotches, so this is already a perfect skin tone. Apple owns Beats so both brands are just marketing niches today. Some people love or hate one brand or another.

Spatial audio works…it’s not pure or ‘authentic’ but it does work. Localization mode simulates a fixed stage and can be stunningly effective with my AirPods Pro – with video it simulates watching a large screen TV or movie. Changing the volume from side to side as you move your head can’t be good for absolute quality, but I use them in situations where better setups aren’t available.

I recently reviewed the Campfire Audio Orbit wireless earbuds for Audiosolace. Here is a link to the review:

Review - Moondrop Space Travel

Recently I reviewed the iFi Go Link and said that they were the best Bluetooth portable source I had heard but they cost around 400€. Today I am looking at something that is completely at the other extreme of the price range, coming in at around 25€.

I already said that I am not a huge fan of TWS but I had heard good things about the Moondrop Space Travel and decided to purchase a set to see if they are just another set of TWS IEMs that work for others but just don’t work for me.

Well, I am glad I did pick them up!

As I purchased these IEMs, there are no companies asking for me to share links. I purchased them from Shenzen Audio but they are also available on Linsoul, AliExpress and probably a few other sites also.


It has been a while since I reviewed anything from Moondrop. Funnily enough, I think that the last set was actually the Nekocake, a set of TWS IEMs that are very similar to these, or rather these are very similar to the Nekocake.

I didn’t mind the Nekocake but, as soon as the review was over, I gave them to a family member that was looking for some TWS IEMs. This is a positive thing because if I thought they were terrible, I would have never given them to her, but on the other hand, if I thought they were great, I would have probably kept them.

Now, before I continue, this review is not going to say that the Space Travel are the best TWS IEMs in the world because they aren’t, yet I have found myself reaching for them a lot and enjoying using them, these will probably stick around in my bag for the foreseeable future.

I definitely think they are worthy of a review, even if it is a brief one (famous last words, as it is never brief by the time I get to the end of it!).

So, let me share my experience with the Space Travel and why I think that, for 25€, these little IEMs are a great buy.


You really can’t get simpler than the presentation of the Moondrop Space Travel. They arrive inside their charging case, in a clear plastic cover (I can’t bring myself to call it a box) with a space in the bottom for the charging cable, a couple of extra sets of tips and the usual manual/docs.

That is it, not much to review here.

Build and aesthetics…

The IEMs themselves are identical to the Nekocake, which is basically just another one of those “Apple Airpods Inspired” designs (not to say copy). This time the cat logo has been replaced with some simple yellow and grey design, with “Space Travel” written on one side.

What has changed is the charging case. Where the Nekocake came with a white case with a flip up lid, the Space Travel use clear plastic with no lid at all. I know that this is something that people have complained about but in my use case, I actually don’t mind it. The IEM case has lived in my bag since I got them (except for removing it to charge) and it fits great in one of the little front pockets. I just unzip the pocket and grab the IEMs and just drop them back in when I have finished.

I understand that this is not something that works for everybody but I’m sure there will be some kind of silicone cover available soon enough and, in case you have the Nekocake, it seems they also fit and work in the Nekocake case.

My only personal complaint is something that I find over and over again with TWS charging cases, the USB-C charging port is on the bottom, meaning you have to lay the case down to charge it. This is a minor gripe but I would still prefer to see the charging port on the back of the case.


The touch controls on the stems of the IEMs are responsive and seem to work well. A simple touch on either side will play or pause the music (or answer/end a call), a double tap on the left is previous track and on the right is next track, with a triple being to summon the assistant.

The Space Travel also have three different modes which you can cycle through by pressing and holding the left or right IEM for 1 second. The modes are Normal, Transparency and Active Noise Cancelling. Rather than a voice telling you what mode you are in, a chinese girl makes a sound, which is “Ummm” for normal, “Shhhh” for ANC and “Heh!” for transparency mode. It’s certainly something original.

Bluetooth pairing mode is entered by holding both sides for 3 seconds and is very quick to both pair and to reconnect each time, although only SBC and AAC codecs are available. Moondrop states 4 hours playback with the IEMs fully charged, with an additional 12 hours available with the use of the case (which takes around an hour to fully recharge the IEMs).

Things are obviously not perfect and I would have liked to have seen LDAC and of course, my pet peeve, volume control on the IEMs. But for 25€, I really can’t bring myself to complain.


As mentioned in functionality, the Space Travel have three modes, Normal, Transparency and ANC. Due to the way the ANC is implemented (the location of the mics) I have not been able to measure the frequency response but when comparing Normal & Transparency, the response is identical (except for the extra background noise of course) and I can’t hear any difference in response with ANC on, so the mode does not influence the frequency response of the IEMs.

While on the subject of ANC, it is fairly decent. It is not the best ANC I have used but the noise reduction is useful. I haven’t travelled with them yet (i.e: I haven’t flown) but with the A/C drone in my office it is effective.

There is also an app that can be installed (at least on Android, I don’t have any iOS devices) and allows the user to select between three different tunings. The app is far from great but once the tuning is selected, it saves to the IEMs, so you can pick it and then not worry about the app.

The three tunings are “Reference”, “Monitor” and “Basshead”. Here is a graph of the three in comparison to my personal preference target for reference as always:

After spending some time trying each of the tunings, I found that I preferred the “Reference” tuning and that is what I have been using since then.

Now, don’t expect these IEMs to be amazing, they are not the best in terms of audiophile performance, yet they still have a very enjoyable performance.

To be totally honest, I haven’t really sat down to have a dedicated in depth listening session with the Space Travel. Usually, when I review something, I spend time with it and then sit down with my list of test tracks to have a focused listen where I pinpoint certain responses to certain tracks. In this case, all I have done is use the Space Travel as and when I wanted to, without really focusing on minute details.

This may make this review null and void for some people but, in my opinion, these IEMs are not really something that I would expect people to choose for dissecting music. These are more of a set to have handy, being able to grab them at any time, without having to worry about them too much. And in those terms, they perform really well.

The “Reference” sound signature has a bit of a boost in the lower ranges, which does a nice job of keeping things smooth but clear, with a boost around the 2.5 to 3kHz mark that works to give things presence. Add those to a very neutral mid range and a decent extension in the upper ranges, and you have a very pleasurable set of IEMs for easy listening.

Not once, in the various weeks that I have been using these IEMs, have I felt that they sounded awful. I haven’t found myself focusing on them and thinking, “damn, that sounds bad on these”, they just played music as I went about my daily routines. And I really think that is the strong point of these IEMs.

They have a pleasurable sound signature, with decent enough detail and performance that is more than satisfactory for 25€. They even have decent sound stage for a set of IEMs.


I know I haven’t gone into depth on the sound of these IEMs, which sort of defeats the purpose of reviewing a set of IEMs, but honestly, they are a decent sounding set of TWS for a very cheap price.

I wouldn’t recommend these to someone who is looking for specific strong point in IEMs, in other words, I wouldn’t put them as the “best bass” or “most detailed” or anything like that. I would simply put them as a 25€ set of TWS that provide a good and enjoyable experience.

And before the question gets asked, yes, I prefer them to the Nekocake which are twice the price. In fact, as someone who really doesn´t like TWS IEMs all that much, I think these are the set that I have spent most time listening to and intend to keep on doing so. They are certainly one of the few sets that I have reviewed as most of the budget TWS sets that come my way end up getting a couple of hours listening and then either returned or thrown in a drawer never to see a battery charger ever again.

As always, this review is avalable in Spanish both on my blog ( and on YouTube (


The real question is how well the ST compares for listening in space versus the Star Trek Space Travel (ST ST) communicators. The ST ST has an extensive and proven history of space travel.


(source 1; source 2)

I suppose ‘fun’ theming is the real purpose of the STs, so it doesn’t matter if buyers throw them in a drawer or leave the clear display case on their desks.


@Resolve has volunteered to go into space with the 5128 and find out.


WWUD: What would Uhura do?..

Air Pods Pro 2 (2023 w/ USB-C case) or the new Sony WF-1000XM5?
Which one would offer the best in audio sound quality?
Are both Federation and Klingon approved for linguistics?

Connection w/ iPhone - Yes, Air Pods win overall + w/ Spatial/Atmos/etc. But for overall hi-res musicality/audiophile ear candy-ness?

Other ones that could interest Uhrua with the BEST sound quality available: new Denon Perl Pro, B&W Pi7 S2, Bose Quiet Comfort II, Final Audio ZE8000, Sennheiser’s and Technics best…
Have at it!!

No input on the wireless earbuds?

I have no idea who Uhura or Uhrua are.

Is you post looking for purchase advice?

If so, then maybe post it here to see if it gets more traction:

Uhura was a character on the old 1960s Star Trek TV show. Her character flew through space every week, and she was famous for wearing the ear-dangling communicator in the photo above. I made a joke per your review of the Space Travel product.

It seems @C1gar1 responded to my joke with Star Trek lingo and then asked for product purchase advice. I think we might have missed the question, thinking it was a continuation of the joke.

Responding directly to @C1gar1, I’ve not heard much quality difference between TWS products once they reach the middle price range. Those tiny devices combine Bluetooth, an amp, a DAC, and driver. They do this using tiny tiny little rechargeable batteries. My approach wouldn’t focus on best sound quality, rather, integration with your computer and phone products. Buy Apple Air Pods Pros if you run Apple, buy Samsung if you run Samsung, etc.


Thanks for the advice. And the Trek-y thing didn’t go over well, I guess. lol
I will probably go with the Apple new gen Pro w/ usb-c. Best Buy has $50 off right away before release!
