跑步用藍芽耳機

calip

I am using backbeat GO with IPHONE 4s, it perform fair I would say,

Pros
1) It hold tight in my ear while running (fast/ slow pace, even I sweat a lot),
2) The connection is ok (I put it on a waist bag)
3) Lightweight, it feels like normal earphone.
4) Microphone reception is good, can answer phone call during running.

Cons
1) Very normal quality on music.
2) Batt is not enough for very long run, (~ 3.5hrs max)
