They just arrived and, while they look and feel very well-made, I noticed a couple problems: 1) I feel like they "choke" my ears. After some minutes, I was almost hurting. But I saw some reviews saying they do put quite some pressure, but tend to loose over time... 2) Maybe they have too much bass? Or is it a consequence of low-level DAC/AMP?
I answer my own first question: I didn't properly adjust the headband.
Yeah, these do have a bit tighter clamping force. It is suggested that you "de-stress" the band by letting the headphones sit over the case over night for some time. What are you using to power these? I wouldn't say these are so bassy to the point that it over powers everything.
I did feel they were comfortable and listened to them for 2 hours out of the box but yeah don't forget to adjust the headband ;) What is your amp/dac? I noticed that out of my phone (S9) the bass is really punchy but unrefined. Through my magni 3, the bass is cleaner and more controlled!
FiiO K1, so yeah, really entry level. Volume isn't a problem, at least for most songs I listen to. The bass did smoothen as the headphones got less tight, but I'm almost sure the problem is my DAC.
I believe fiio k1 is a usb powered combo unit? People have mentioned getting a better sound with a wall powered amp. I didn't really do much of an a/best when I swapped out my udac 3 for a khadas tone board + jds atom. Idk, it's something you could look into if you want to try it out and see if it helps.
These are absolutely not meant to be bassy by any means so it's definitely a "fault"/character shining through them from elsewhere in your chain. The clamp force is pretty obnoxious to start with, there are a few tutorials on youtube/the internet in general showing how you can forcefully loosen it pretty easily - it's not a dangerous procedure if you do it properly even though it may seem a little sketchy, it definitely helps. I've personally done it with all 3 pairs of 650s I've owned over the past decade.
