its an insanely cool tech piece...the audio quality is great for phonecalls. Can def. hear everything, and the microphone is also really good quality (with wind dampening qualities, so you can carry on convos in incliment weather)
the ipod controls are also extremely convenient.
basically, it may be expensive, but some of the convenience features are exactly what jackets have needed for awhile. Nice to be able to voice dial someone without even touching your phone
