This bluetooth has a long charge life, and the reception is excellent. The problem I have with this product is that it is hard to keep in your ear. The little plastic hook that comes with it pops off and the ear peace falls out if one of the three ear plugs don't fit just right. It also has a charger that is difficult to operate. If it is not placed properly it will not charge.This is more work than it is worth.

I think the people who complain about being unable to charge the device did not read the manual. Do they realize that it is not supposed to stay red but to flash intermittently while charging? I had no problem whatsoever charging this headset.
The best part of this headset for me is that it comes with the small ear piece. My ears and ear canals are very small and everything falls out. I wear glasses so I don't want to wear a loop over my ear.
It sounds great to me and those I am calling.
I reccommend this headset.

Love the different adaptors especially the marker-sized one that charges thru a battery. Portable, thus great for people who forgets to bring the usual wire charger. And the 3 ear pieces gives everyone a size to fit.
Only regret, didn't know about the product sooner.

I think I paid about $60 for mine. Didn't want to spend $100 or so for a top of the line Bluetooth headset; this was my first one. Aside from the comments others have made about the charger, it's really difficult to get it turned off properly. The manual says to hit the button for 6-8 seconds until the indicator light turns red or until you hear a beep. Okay- done...and my phone tells me it's no longer connected. But then the next time I went to use it a couple of days later, it was dead. Seems that when you follow those instructions, it's off, but it's not really off. The blue light still flashes every few seconds, running the battery down. So, you have to keep messing with the button trying to find precisely the right combination and timing of button-pushing so that it turns off completely, and doesn't turn itself back on again. You have to check to make sure the blue light is no longer flashing so that it really is off. When I'm talking on it, I'm told that I sound really far away, although I can hear just fine. I'm also told that minor little background noises (opening a bag of potatoe chips for example) are really amplified to the person you're speaking with. You do get three different sized rubber earpieces, so you should find a comfortable fit, however the earpiece is designed to come off when you rotate it to a certain postition. That position is extremely close to the position that you would use when it's in your ear, so the earpiece will sometimes come off when you don't want it to. Looks like the price has come down now, so if you just want a cheap Bluetooth headset to leave in your car, and you don't plan to use it much, it may be okay. If you're someone who spends a lot of time using one, however, you'll want to keep shopping.
