After purchasing these BT headphones for $99 it took me 3 hours and long 10 minutes to fully charge them. Instruction says it should take only 2 hours. My iphone paired them right away (with out asking me for 4 letter pin). I've tryed them by calling my friend. Clarity of call was great. Than I decided to listen to some music from my ipod/iphone and the sound came out throu iphone speaker, not throu my comfortable BT headphones. I got back on my computer and did more research about which ones will work with my iphone....Get ready to be dissapoint. All IPHONES do NOT support A2DP ( [...]). It's hardware that let the music stream throu wireless headphones. Iphone just don't have it so do not bother looking, searching and sweating to find one compatible with our super iphones. Even know my dreams were crusched by not being able to listen to the music wirelessly I will still keep those Jabra headphones because I can't stand using other kind of headset or headphones that you have to stick it in your ear.Overall: Jabra BT is very comfortable (fits very well on my head (ears) and it's not as heavy as other BT headphones), stream calls with perfect sound, it have sensitive buttons so be carefull while you putting them down to not make extra phone call)...;)
