I use Sony’s MDR-EX70LP earbuds, which have lasted an incredible 5 years and counting. I also have a pair of MDR-NC11 noise-canceling earbuds, which are superb when traveling to block out noise. Bluetooth audio is definitely in its infancy, and with only 723kbps of peak data transfer to work with, it’ll probably be in the next BT spec revision that provides for a hi-fi audio profile. I currently use a Bluetooth headset with my phone, and the audio/range/battery all could stand to be improved.
