Not that I'm advocating doing away with wired earphones completely, but I'd just like to mention how ridiculously inexpensive passable bluetooth earphones have become. "Bluedio N2" stereo bluetooth IEMs (incl mic/remote)... SUB-$10! Delivered! From China!
No, the sound quality is not as good as my wired Etymotics, but being unattached to the phone is often preferable. These things are head and shoulders the best bang/buck I've ever had in consumer electronics. Stockpiled 3 pairs.
