Has anyone compared them to the Sony MDR-1A? Thoughts on comfort and SQ?

How long have you had these? If you just bought them and they're defective, having to send them out for a 2-5 week repair seems ridiculous. I would just exchange them.

Anyone know when these are supposed to release in the US?

That's unfortunate. I went through like 5 1Rs due to creaking and jack rattle before giving up on them. It seems like they fixed the jack rattle with the 1A, but not the creaking. It's weird because their marketing materials go out of their way to talk about how silent the joints are, but...

Anyone know if the wireless version is significantly heavier than the wired?

Is this the Apple or Android version? It looks like only the wired-only versions on Amazon specify if they include the iOS or Android cable.   EDIT: Nevermind, it was clarified earlier in the thread that it's a plain cable with buttons on the headphone itself.

I'm thinking of getting the standard non-wireless version. Is the passive isolation enough to comfortably listen on an airplane without blasting the volume?

How bad is the cup creaking on these? I had and returned the 1R in the past because every time I'd turn my head one of the cups would creak (in addition to rattling where the cable connects into the jack).

I tried and returned the original 1Rs a few months ago due to jack rattle and creaking (any head movement would result in creaking sounds). I went through several replacements and they all had those issues.    Does the MK2 still have the jack rattle issue? And, is there any creaking when you...

Quote: Same here -- four units, all with creaking ear cups. The irony of it all is that Sony brags about how quiet they are:     The noisiest headphone I've ever encountered just so happens to be the only one specifically marketed as being quiet.

Quote: I know this is getting into "Sound Science" territory, but the only way to know for sure is conducting a proper ABX test. People often "hear" a change in sound from various mods and new cables due to a combination of placebo and expectation bias. I wouldn't perform any mods or cable...

Quote: Usually, I'd agree. However, in this case, it appears to be a design defect, not a statistical manufacturing defect. I bought 4 MDR-1Rs, and all 4 exhibited the loose jack issue (3 out of the box, the 4th started to loosen up after a couple days).   While most products will have...

I'm not convinced an amp makes any audible difference other than loudness (by audible I mean passable in an ABX test).   My Macbook Air drives my DT770 Pro 80s way beyond listenable volume, yet everyone claims they still need an external amp to sound their best. I'm wondering if they're...

Quote: Interesting rule. Post edited. 

Quote: I've read some wildly varying opinions on amping the DT770 80 ranging from tightening up the bass to having no audible effect other than loudness. From what you describe, it sounds like amping them made them an entirely different headphone.
