Summary: I own 2 of these very nice sound and connectivity just wished they put more effort in the quality of the parts that hold it to your ear.
Pros: good battery life using media about 6 hours. Comfortable on ear comes with couple different options for comfort and use. good sound quality easy to use and connect to cell phone or tablet
Cons: the piece that goes around ear is cheap plastic even though it is comfortable after a couple months of use it will break. I had to craft my own to replace the cheap plastic one that comes with the unit.
Summary: not really worth the money unless you get it on sale like i did and even then if i knew what i know now i would probably avoid it.
Pros: the phone functions seem to work very well. good quality, the speaker volume is pretty low even when topped out.
Cons: the music streaming is awful. It worked fine for the first day when i had the phone in my front pocket but then the next day i kept it in my back pocket of my cycling jersey and it skipped more then an old cd player with no skip protection. It was so bad i ended up just turning it off. Apparently...
Cons: When I first got the device it would loose connection to the caller if I talked for more then 3 minutes. Now it shows that it is connected but the person on the other line can hear nothing. What a waste of time!
Excerpt: i bought this product but started having problems with it immediately. i loose connection at the slightest movement away from the phone. it did not serve me at all like a bluetooth should and i was very dissatisfied with it
