Thanks for the tip on the MDR1000X, I've just had a little read on them and I think I'll go somewhere and give 'em a try, they seem like a good pair of desperates; I've always fancied a set of cordless but never found the sound acceptable, these sound just the job. Nicely styled, too.
Some nice features too Mac. I was looking at the Bose, but there's no way of turning off the noise cancellation, or advancing tracks. The Sonys allow a 'voice' option to hear someone talking, or maybe travel info at an airport, ambient noise setting, proper noise cancellation, vol up and down, track advance or back, phone answering. And best feature, put one hand onto the right earpiece and music stops, and external mics allow conversation. All without taking them off your head.
I tried the Bose, Sennheisers and the Sony. Sony won hands down on sound and controls. Sennheisers were good, stylish, but are big and don't fold down too much, plus a bit bass heavy. The Sony were designed as direct competition to the excellent noise cancellation of the Bose. They're a fuller sound, plus all the extras above made them a must have.
