Just my story with Amiron wireless. I wanted the best wireless headphones and started with significant budget.
I have tested and tried almost all the wireless headphones. (Except the ATH-DSR9BT)
I bought Amiron wireless, returned it due to its size. I figured wireless just does not cut it for me and then got an iSine 20 and AQ NightOwl both of which are keepers for their own unique SQ. But in the end I ended up buying the Amiron wireless again as I was missing its energy/dynamics and wireless nature. These are miles ahead of anything wireless in my opinion. Amazing headphones to use at work and home.
What I have found is the wired headphones really need an amp to shine, iSine20 ofcourse works amazing with the cipher cable. Even ES100 does not do justice to my NO, I feel. I just dont have that kind of space/time/money to setup a fixed amp or a handheld amp/player. Amiron is kind of best of both worlds, as it has a custom DAC/amp built in and really makes the headphones shine.
Second for wireless? B&W PX but Amirons are in a different league altogether. I also liked the MW07 from Master and Dynamics if you want truly wireless earbuds.
You can be patient and pick these up for 600$ at Amazon (since they drop prices everyday for these until they sell out), for that price it is a steal.
Update: Ended up returning them

I decided to wait for more reviews to come out. I am still new to this so I ended up getting some beginner stuff - HE400 (used) + FiiO Q5 to try out open back headphones. While the sound stage is better and wider on the Amiron wireless, HE400's bass won me over. Still I miss them, maybe after some community adoption and feedback I might even go back to the Amiron wireless!
