Summary: I recently got the 1RBT because I had a couple of Sony vouchers, and I have to say, while I am still uncertain of it's full retail price, I do really love this pair of headphones. The retail price is $498 Singapore Dollars.
My experience with headphones were on the lower-end Grados and AKGs.
Pros: Interesting sound, easy Bluetooth setup, comfortable in cool climates
Cons: Interesting sound, sweaty ears in hot climates
Excerpt: Looking for a good quality sound and the convenience of wireless headphones. These do the job perfectly well, a good balanced sound with no particular bias towards base or high notes. Reasonably comfortable on the ears.
Summary: just got these headphones and they are amazinnnggg, great mids, great bass but not too much, been waiting for these forever but i'm returning them because for some reason the functions on the ear cups didn't work and the bluetooth didn't seem to work either and i tried on 3 different devices.
Excerpt: Had my 1BT's for 5 months now, they replaced my wireless beats. I'm very very impressed with the fantastic sound quality (I mainly play dance & R&B) and the 1BT's features! Most impressive is the amazing battery life, i use mine every single day but only need to charge them every 7-9 days!!!!
Summary: for bluetooth headphones they are great sounding, and battery life is more than useful. Ergonomics are a little off as I don't use them too often I can never remember where the buttons are when it is on my head!
Summary: Great pair of over ear headphones, they go on forever. My mobile phone died and needed recharging before these did. They are a little on the large side, very light at first but once you listen to them on a long flight you certainly notice the weight.
