Any one hear any news about a new HD 800 open back replacement [other than the 800S]

Like an 82X open back?

…what have you been hearing…

Nothing :[ hoping some one else heard sumthin,

I heard rumors around the ADX5000 like 7months before it was announced

Sennheiser x Massdrop 8XX?!?!

1 Like

I could see that as a possibility - much like what happened with the HD650/HD6XX and then the HD660S, though in this case the HD800S would be pre-dating the HD8XX prior to the HD800 being retired.

I’d be very surprised if Sennheiser (on their own) came out with a new open-back HD8XX(S) anytime soon.


That seems very likely! Them doing an MD Collab before retiring the HD 800

HD800 with Helmholtz resonator but the original bass tuning.



I would say a HD 8XX is probably unlikely but who knows, it could happen. The issue with Sennheiser doing “xx colabs is it completely destroys the brand value of their regular line-up and none of those regular headphones can be sold at msrp.

The HD 800S and HD 820 are the only Sennheiser headphones that are ( or close to) sold at msrp so if they released a 8xx they would lose control of the market there as well.

Something like a 7xx where they changed the tuning a little bit would make sense since they don’t have anything similar in their line-up. Obviously wouldn’t be as popular as a 8xx but it would keep their high-end value intact.


I guess the flip-side is volume. The development costs in the HD 800 line are already sunk, so if they could dramatically increase the volume of units they move by doing a Massdrop collab HD?XX at a lower price, it could still make financial sense. That said, I have no idea how Massdrop volumes on something like the HD6XX compare to regular HD650 sales back in its heyday.

Neither Massdrop nor Sennheiser had a clue about the 6XX prior to its release. The first drop sold out immediately and had been characterized as a one-off. They then rereleased it and briefly tried to up the price to $250, but reduced it again.

Headphones had been a different market and a niche prior to Beats initiating wider use.

This reminds me of the rinky-dink PC manufacturers prior to the IBM PC. Little vision.

I would actually prefer a HD7XX to the HD8XX at this stage, and what you say is very accurate. I think with the HD700 being un-popular and since they already have the molds and manufacturing in place more or less it seems like a great candidate for a colab! I would buy one!

I thought the 660s was what they did with those HD 700 drivers?

But yes they do have the enclosures around too!

As for the HD 800, the second hand price is around $800 or so now. I would think moving those last final pesky HD 800 Non S models would be ideal, since the 800S is both more expensive and also “corrected” also MD is some what limited to the US. Once shipping and customs fee’s come into play international customers are better off with buying manufacturer stock from a more accessible vendor

True, but I don’t think they would be pushing used HD800 or already made HD800, it would be using the molds for a colab, and available parts. If they put out a colab for the HD800 it would be a direct competitor to the HD800S and would be bad for business.

The transducer from the HD700 I thought was stated as not the same as the 660? Similar but not the same? Or maybe tweaked HD700 transducers…

Anyhow I would love either option but get why they wouldn’t go HD8XX as it would undercut to heavily their flagship headphones


Good point, I had not considered that an HD 8XX would undercut HD 800S sales!

Me too. The HD700 is an underrated headphone but that’s my opinion. I know lots of people hate it but I like it.:grin:

Has anyone tried the new Sennheiser True Wireless Momentums? Really curious how they sound!

1 Like

We hopefully have some of them arriving this week but they are incredibly back-ordered from Sennheiser right now.

I didn’t get the chance to try them out myself yet but I have read some mixed impressions of them. I know some reddit users do not like them as they find the bass is super bloated while others say they sound great.

I think Amazon should be shipping out their pre-orders soon so there will be a lot more impressions out there for the Momentum True Wireless soon.


Hmm I wonder if it has the sound signature of the other Momentum lineup. I used to own both the On-Ear and Over-ear Momentum v1 and I found them a great looking headphone but kind of overpriced in sound quality. I found the mid-bass hump a bit too much and muddying the sound. I don’t know if this has gotten better over the revisions to it.

I’m new to this and was wondering, my Sennheiser 660S headphones came with a balanced cable that has a 4mm jack (some new standard I read someplace?). I got a FiiO M9 DAP that has a balanced output, but it’s 2.5 mm. Is there a reputable place to purchase a Sennheiser compatible cable with the correct jack?
