Well, on top of the headset, there's the dual dock /attached USB cable and the travel cable (same as USB cable but charges phone and headset.) I bought one used on eBay for $79. Definitely not worth $129. The only things I liked were the conveniences of the dual dock and travel cable, and style. The volume was never loud enough for me to hear even in quiet environments. I couldn't imagine anybody using it while driving.
Motorola HS850 was my primary BT, until I picked one up brand new for $80 on CL. The Apple BT is limited in regards to range, it's difficult to press the button on the BT and takes some getting use to, no lanyard or a place to put it when not in use, it's very light and easy to misplace or drop, (I did find a lanyard that attached to the earpiece quite nicely), the cushions fall off and make for a tight fit in the ear, BT doesn't sit snuggly in the ear at times, a quick turn of the head and it will pop-out. Beyond all that, it's a pretty nice BT for $80, but not for $129 plus tax. No way to recharge BT while in the car, but that's normal for all BTs. Sound is not a problem, but it seems that I have it on the highest level in order to hear any conversations. IMHO
