The Lubix UBHS-NC1 (and the LC1, which features a screen), tries to be an all-in-one wireless headset for music and phone calls. Unfortunately, the sound quality is sorely lacking, the mic is almost useless in busy places like fast food restaurants, and they barely fit.Play any music with lots of treble or bass and you'll hear distortion in the speakers. I use these with a 30gb iPod Video and I had to go into the iPod's equalizer settings to find a setting that wouldn't sound like they were destroying the speakers. In fact, I had to turn the equalizer off to get decent sound. The headset features 4 audio modes, and each one has their own pros and cons (it's really up to individual taste), but none actually improved the quality of the sound.The unit may have been better if they went with earbuds that went inside your ear, instead of just resting outside of it. While I do not prefer sticking something in my ear, this may have helped hold the unit in place; they fell out constantly. Yes, the box comes with different size padding for different sized ears, but none of them worked. Also, they take 2 hours to charge completely, which is an hour longer than even my phone.As I mentioned earlier, the mic is useless in public. It's fine in a quiet environment like your home or office, but go outside into a restaurant, or a busy street, and I had callers tell me to call them back because all they heard was noise.On the plus side, answering calls is easy: just press the appropriate button and you're all set. For those using it with multiple items, the multipoint bluetooth connections work well. I used it with the aforementioned iPod as well as a MyTouch 3G; neither device had trouble connecting. In quiet areas, the mic was fine; call quality both ways was good. If your music player or phone supports it, the unit can also control your tunes, giving you the ability to raise or lower volume, skip tracks, and play/pause.Overall, if you're not looking for the best (or even mediocre) sound quality, and you're just looking for something to use in the office or at home, these aren't bad. Just don't buy them from Lubix directly as they charge $45+ for them, and they most certainly are not worth that much. If you're looking for something with better audio and mic quality, look elsewhere.
