Excerpt: It was quite good while it lasted! This headset had a good well designed, very usable form-factor. Extremely comfortable. Excellent battery-life. And the vocal-interface was an amazing bonus. However, all this goodness was let down by what seems to be extremely poor build and material quality....
Summary: Sync'd with Blackberry Curve instantly (be sure to tell your Blackberry to connect automatically after first time) and worked perfectly right out of the box. Voice recognition is a great feature, although occasionally it gets its numbers confused.
Summary: Great Bluetooth for the iphone 4, sounds great even with the windows open going 60. The only drawback is when the phone rings instead of playing your ring tone in the earpiece it recites the Phone # of the person calling and other than my close friends and family it doesn't help to have random numbers recited in my ear that mean nothing to me. Otherwise good sound quality at a good price.
Pros: Clear Signal, Comfortable, Easy To Use, Good Sound, Good Volume Control, Lightweight, Long Battery Life
