This Headset works with ctia protocol whereas few mobiles like Sony ericssion xperia supports omtp, and so this Accessory is not supported. Please make sure your mobile supports this Headset. Otherwise this is worth the bucks with better build and unique design.

Satisfactory product.
Pros:
1. Tangle free wires.
3. Clean and clear mid range. Treble peaking near 6KHz.
4. Extra ear pads in the box.

Cons:
1. Absolutely no bass. LF response starts at 250 Hz or higher.
2. Ear buds are made of slippery rubber. They slip off from your ears all by themselves even when you are sitting still.
3. Earphone diaphragm makes murmuring noise when inserted into the ear, which means it may not last long enough.

1. looking attractive :)
2. 3/5 for bass.
3. + for volume control and big wire.
4. 3/5 for quality.
5. - for non-adjustable ear buds. should have included another little smaller size ear buds.
5. overall felt comfortable. 4/5 for the worth of 800 :)

Everything is super like, Sound effect, Wow base, attractive color, microphone and volume control!!!!

But one thing I felt bad is often I need to adjust the speaker which too big for my ears, eventhough I changed the ear buds.
