If Apple made headphones these would be them.
I don't usually feel inspired to write reviews however these headphones really deserve praise. My other favourite (earphones) are Klipsch X10's and whilst the BH-905 are not so revealing as the X10's they are fantastic. I smile every time that I switch on the noise cancelling, I count to three and the background noise disappears. It is even soothing to wear them with noise cancelling enabled and no music. The audio performance is very good through Bluetooth Stereo. I get the best sound by using Apple Lossless encoded source material so that the audio reaching the headphones has only been lossy compressed once (in order to transmit the BT audio). If music via Bluetooth is not your thing then you can use the supplied cable to connect but the freedom of wireless is a big advantage. Taking handsfree phone calls on a noisy Oxford Street is a pleasure too. Could they be improved? Well audio-wise I doubt it, some different styles and colours may widen the appeal and of course they are expensive (but good value and even more so at the current price on Play.com). Really I love them and would recommend that you try them. Do what I did - go and audition them at the Nokia Shop then buy on-line :-o
