One of these days we gotta have NJ/NY meet-up of head-fiers just so we can put together our headphones into a sound pool lol!
I had a little bit of time to listen to 02 in the morning, than put it through 3+ hr of burn in with pink noise loop (actually saw some improvement in treble, after burn in felt a bit tighter and not as harsh). My initial impression: they are mid-centric with a detailed, bright, upfront mids and great upper frequency sparkle. Bass has a great quality, but anemic when it comes to quantity. You hear a punch but there is no weight behind it, and no sub-bass texture. I tested it both on my X5 and Note 2. Easy to drive from either. Actually 02 reminds me a lot of UE900, just a tad less details. In general I think it's pretty good considering you get a very close sound signature with only 2 BA driver and for at least half of the price. Also, upper mids/treble details remind me a little bit of surgical precision of Etymotic HF2.
These have a great build quality, and very manageable shape to fit comfortable in your ears. Removable cable is durable; 2-pin connection is secure. The memory flex wire is ok, and I'm very happy AT included a rectangular zip case - keeps pre-shaped wires from being bent inside of the case.. For under $200 these definitely have a great value, but if you are craving more bass - probably not the best choice. Will be curious to hear your 03 impression.
