I think with Bluetooth headphones, with current technology, the quality of sound has to be balanced with the ease of use without wires. Given that these are actually well made and the wireless range seems to be quite impressive, they are really convenient to use.
Because of that, I spent most of yesterday listening to the radio about the house while working and even watched tv with them. It's also nice to listen to podcasts on the move, so I did a lot of listening with them rather than use my posh, wired ones!!
The first Bluetooth headphone to get close to wired quality would be a killer headphone, but the system itself can't help but impact sound. However, ease of use means that mine is getting a lot of use, so it's a good job that they have a long battery life as well!!
I've been trying out the Ausdom ANC7 which is soon to appear and again, this one is a good 'n as well.
Similar in sound to the M05, perhaps a little more 'balanced' sounding actually, with excellent wireless range..... I'm back out in the garden with it!! This one will come with a really nice case and noise cancellation. Being a bit crazy, I sat watching TV on my Ipad next to the washing machine at home and I could barely hear it!! (The washing machine, that is

)
Slightly more comfy pads too.
