These peaked my interest at some point. Customer reviews online are good, reputable audio reviewers seem to either ignore these or not know these exist exception, but I don’t speak/read norwegian. Which is a shame, because they look very interesting to me:
Nice. I hope you enjoy them and I look forward to you impressions.
On a side, I picked up another Palmer in addition to another RNHP. It’s a great little devise that does so much for only $20. Great recommendation, thanks again.
I had a pair of those RP-HD10 a number of years ago. I think they’re one of the worst pair of headphones I’ve yet heard - only beaten by the Flare Audio R1 and airline earbuds for the worst.
Edit: I lied. A number of old vintage headphones beat it for the worst sounding I’ve heard.
I remembered the midrange sounding very uneven with parts sounding way too withdrawn and other parts being way too forward. IIRC, the treble was fairly sharp sounding. I don’t remember what I thought about the bass response though.
An online buddy of mine measured his on his MiniDSP EARS, and I believe the compensation used is HPN:
I remember trying some Technics headphones last year and they were complete crap (sorry, can’t find a better word - not a native speaker!). Panasonic really isn’t the best when it comes to headphones, which is quite a bummer given they make fantastic audio products.
Impressions
Earpads are nice (works well with my glasses). headband cushion is like a worn-in DT-770 but thicker.
3.5mm jack on the headphone is in such a nice spot that DIYing a cable in the future is easy (it is exposed, no wierd sunken in nonsense stares at M40x’s).
The adjustment mechanism for hight is above average in feel, the back/forth adjustment for the earcups is a 10/10 idea.
Update
Have been using them since I got them with only a few hours swapping to my other pairs (PortaPros, M40x, AD500x, T50RP mk3 and K-712 Pro’s) to give better points of reference. I am not that well versed in the speecific terminology
They are by far more comfortable than the M40x, don’t isolate nearly as good. Correction: They isolate differently. Very impressed with the feel and finnish (then again, they are my second most expensive pair).
Sound
Sound wise, they have one quirk I can’t put my finger on yet. Somewhere in the mids there is some oddness. Pentatonix - Hallelujah sounds absolutely fine, all voices present and full. Eurielle - Carry Me sounds recessed or distant.
In direct comparison to the K-712 Pro’s, and exclusively listening to music where vocals are the main attraction, I’d take the K-712’s
Bass is good quality. Quantity is less than I expected, which in a sense is good. Never drowns out anything. Similar to the K-712 Pro’s in this regard, just with the bass boost that comes from the RP-HD10’s being closed back. If you need “a little extra low end”, give them some power (tested on BasX A-100 with limiting resistors engaged).
Mids are the odd one, as mentioned above. Fine for instruments in Blues/Rock/Metal/Electronic
Treble is in check, no piercing spikes and not a Beyerdynamic-V (I dislike that in particular). Does not need dense foam/toilet paper mods like the T50RP. All good here!
General Notes
Cables feel oddly flimsy
On both cables, one end has a molded on plastic connector and the other is a metal one
Very comfy (thick cushion on the headband & soft ear pads) + the two way adjustment
