Excerpt: During busy times of the day, lunch, dinner,Etc., there is a lot of screeching noises on other end, per conversations. Running water or opening mail is extremely loud as well. I originally purchased for headset for net meetings, but use as a music device instead.
Pros: Fits well in ear, Good Sound, Lightweight, Long Battery Life
Summary: I bought this for one specific purpose, background noise reduction on my end. Advertising claims aside, it simply isn't there yet. Comments from various people I spoke with ranged from "you sound like you're under water" to "I can understand you but your voice is garbled". I'll concede that I may have gotten a bad one, but I've tried several, including the top rated one that apparently works from vibrations in the bone rather than a normal microphone.
Summary: Pros: Incoming call is loud and clear Cons: My ear aches after wearing it for 30 minutes. People I called complained that my voice was not clear but confirmed it was clear after disconnecting my phone and talking directly thru my iPhone 4S.
Summary: I am a Bluetooth junky. Which means I am always buying Bluetooth's and trying new and different ones. I only had the Bluetooth for 6hrs and it is echoing. I can hear my own voice echo back while I'm talking to a person. The mic was not good, either it was too low or it picked up a lot of background noise, because people could barely hear me. Also the smallest ear piece hurts my ear as well as my head. So you can only wear it for a max period of time of like 15mins.
Summary: Laite oli erinomainen (mukava, hyvä äänenlaatu, helppokäyttöinen), mutta suureksi pettymyksekseni akku kuoli jo reilun vuoden käytön jälkeen. Melkein sadan euron tuotteen pitäisi mielestäni olla varustettu laadukkaammalla akulla.
