Sound quality is very impressive, making the music clearer and with no background noise

I find that most people on the other end of the line seem to complain about alot of background noise from me

I wear it most of the day at work with my hair down and listen to podcasts as background noise while I work at my computer

Sound was muffled on my end, and the caller heard more background noise instead of what I was saying.

any background noise makes it difficult to hear

I'm pleased to report that the replacement unit does not have the same background noise

But the background noise is distracting enough that I believe I will be returning it

Works as intended, people hear me well, even with background noise, which is amazing, considering it's sitting in my ear

There is a constant varying high pitched background noise on the earpiece I received, that's particularly noticeable during quiet moments in movies or between tracks.

The transmission is clear and my friends did not notice background noise.

The background noise of the truck will bury your voice in sound.

It performs now as good as it did when I first received it

Though the problems experience with the first device were not as prominent as with the

callers could not hear me as well as I could hear them

So far the new has been working as it should.

Did not iritate or hurt my ear as with some other BT ear

No customer support as it's wrong number on website.

About the only thing I don't care for much is that the "voice" which comes on when it powers on & off as well as when the devise syncs with my iPhone is a little smarmy.

However the battery would died after a few hours of use, and the microphone on it wouldn't always worked as it should.

Be careful not to lose earpiece as it is very small.

I used primarily for listening to my music at work, however, calls would come in and were as clear as if talking directly into the phone

Not what I was expecting people can’t hear u good as they stated I won’t pay more than $5 for it

U won’t regret it.

Amazing I love it, great to work out, battery life is

In less than a week, I’ve been contacted 2 to 3 times by e-mail with an apology, a plea for a second chance and to see if I have received my product
