The good... Good sound, and comfortable in the ear and very easy to use.
The bad... 1 hour of talk time. You cannot simply buy another power adapter for the earpiece, you have to buy that and the little plastic cylinder to have another charger.
AND one question for all the manufacturers, other than Motorola. "Have you ever heard of USB/Mini USB?". I am sure we are all sick to the teeth of buying new cell phones and earpieces, only to find that the manufacturers, in an effort to extend their revenue streams, have created another completely different power connector.
Bottom line, don't buy this, buy something with a decent battery life and a mini USB connector for power.
Rating: - Good sound quality, good fit is short-lived
The sound quality of this unit is good enough for my needs, though the volume does not go as low as I'd like sometimes when the other party is very loud.
My major gripe is that with the proper sized earpiece, the unit rotates so that it hangs straight down making my voice muffled to the other party. Adding the optional ear loop works OK but this setup tends to fall apart very easily. I think the reality is that for good stability you need the ear loop, but again, the thing tends to fall apart too easily (not break mind you but the earpiece falls off allowing the ear loop to also fall off).
I will look for a more stable solution in the future.
Rating: - First blue tooth ear piece, and its a good one!
This blue tooth headpiece works great with my Samsung SCH-u740 (dual flip phone). The only issues I have is that it's battery life doesn't seem to be as long as I would like, and sometimes the reception is a little raspy. But all in all i would recommend it.
Rating: - Good enough
The headset works fine... The only thing that I find annoying is the recharger that it gets placed into. It doesn't seat firmly and could be improved.
Rating: - the best
this headset is the best. it's lightweight enough to not even notice it. the sound is great. HOWEVER, do not try using it with a treo 680. you'll regret it. but with an iPhone - stellar.
