These Motorola headphones are included in the V-Cast Music Essentials kit sold by Verizon and are worthless if you want to use them in anyplace that has any ambient noise. The earpieces are hyper-stylish flat discs with rather sharp edges that cannot seat in your ear at all (unless you have ear canals the size of dimes); they seat in your ear worse than iPod headphones, makiing it impossible to use them on, say, the bus. What they were thinking, I'll never know: using them in the car is illegal (both ears can't be covered) and they are useless for exercising: they fall out just sitting there, never mind trying to jog with them. Someone is going to make a mint making in-ear adapters; Motorola would be well advised to just offer a microphone/clip thing you can plug a pair of decent in-ears into in future.
