I have been using this piece since last two months and i feel no glitch in voice clarity... People complaining about the poor sound quality may not have used that with good phones...

I hv tried this earphone in mid of a crowded market and it has not disappointed me yet... built quality is good within the price range..

It's not a chinese product...its from Denmark and so we are getting a better quality than other competitors..!! i hv used Nokia and also plantronics... still my vote goes to J...

Pros:
1. Good sound quality.
2. Talk time of nearly 6 hours.
3. Sexy Looks
4. Supports call rejection, waiting, conference and other smart features.

Cons:
1. The most serious drawback is that this device just has a single button to control everything from power to smart features. If you want to use all advances features, you must read the manual everytime. The reason being, it contains over 10 instructions such has "tap button", "hold button for 2 sec", "hold button for 5 sec", "triple tap ...

Bought this product from GenuineBuys sellers. Product got delivered in 2 days but the call quality is below worse. I have HTC Desire 820.

I got the device today & was so frustrated that I had to write the review today only.

1. The other person on call is not able to hear my voice clearly (voice breaks).
2. Lot of disturbance during the call for the caller & dialer.
3. The voice suddenly drops during the call.

Got the replacement done which resolved my first two problems but the third one ...

Device is good but not supports music play back

Bought it today ...as of now working smooth but the receivers voice seems to be on a lower side. Hope it works well and performs consistently.

Its good voice clarity and best to use and nice model in black but only one thing is ear piece is little big

ear has pain

This is a pretty decent bluetooth headset for the price. It works very well. Audio quality is good. Mic is decent. The only thing is I couldn't wear it for a long time because my ear started paining.
Other than that it is a good product.

Bought this about a month ago. Have two phones paired to it and it works pretty good.
With a decent bluetooth range and a good call voice quality, the product has been priced optimally to suit your needs.
The only minor drawback that i feel is the diameter of the ear piece, Keeping it on for a long time might hurt the ear.

Before this one I used Jabra Easy go Black that one I purchased from Reliance Digital with Cost 2300.But this one range of connectivity is better than easy go.I think range under 1000-2000 quality is similar no big difference.But this one is little heavy and somehow tight to fit into ear thats it and no more extra external on/off button(Long hold this is the power on /off and call both together).for women its not suitable for their ear i must say.But quality and sound everything is good no do...

Have tried lots of Bluetooth from Samsung to syska but this is the best of all this is my third purchase of same product earlier being lost and stolen. Excellent sound clarity excellent battery life and very easy to use. Just go for it.
