When I saw this headset and its associated reviews, I immediately threw $150 at it and had it overnighted. (Thank you, Amazon Prime!) I've used it for 3 days now, I'm on and off my phone all day every day for about 18 hours (work). So... I hate it.

I have used multiple bluetooths over the years, because I can't drive and talk on the phone without wrecking my car, and I'm in my car all day for my job. I have used several Plantronics, some I liked, some I loved. My cat ate many of them because plantronics apparently makes a tasty device. I have used an inexpensive Samsung and a moderately expensive Motorola model too. I have liked most, loved some and hated none until now. My most important requirements are clear conversation, noise reduction and talk time. Every single one of the afore-mentioned bluetooths were better than this one. I forgot to verify my requirements, in my excitement to get this highly rated BT.

This thing lasted just exactly 3.5 hours before repeatedly beeping its death knell in my ear. This caused me to go look up the model and see that I had in fact inadvertently bought a bluetooth with a ridiculously short battery life. In this day and age, who makes bluetooths that die so fast? This is supposed to be a bluetooth to listen to music, answer your phone, whatever.. but apparently you can only do it for about 4 hours and then it's toast. Personally, I do not care how great the music sounds (it wasn't that great), if the battery drops dead in 4 hours, it's useless to me.

Just picked up a Plantronics M50. It does everything I need and lasts 11 hours. In fact, I think it lasted longer than 11 hours. The sound quality is perfect for calls and it's not bad at all for music, though I have headphones if I need music.

So if you're shopping for a bluetooth to make and receive phone calls, and you'd like it to last all day, this is not your bluetooth. I'm giving this Bose BT 2 stars because it paired fast and it was comfortable.
