For all you frustrated Iphone users this now works!!!!! I searched forever for a bluetooth headset for iphone the only one available was upwards of $200. I didn't realize until after I bought this through a different website that it was not iphone compatable for music only phone calls.it was not returnable from that particular site, and only figured out after spending another $50 on the sony adapter (wich also does work with iphone)that after having the done lastest iphone update this DOES NOW WORK YEAH!!!! with iphone without the need for the adapter. so now i can retun the adapter and get $50 back. Performance wise it serves it's purpose for me. I use it to mow the lawn and do yardwork and had no prob with sound or it cutting out as others have reported. It does go a fair distance I didn't measure but is far enough for most activities. I keep the iphone with me when I mow just because the yard is so big I would have to keep moving the phone with me anyway.
