quality of voice is good. this head set is not for normal users. 1. plastic which holds the earphones is very sensitive... will break within a week or two 2. earphones go below your ears, keeps sliding, you will have to pull the whole set up.
The outer plastic is flimsy, but the sound quality for this cost is quit awesome! Noise cancellation is a bit low. And the sound doesn't scatter at a higher volume. Great product. Must buy if you are on a budget, but if you can spend a few more hundreds I would suggest the Sennheiser HD 180 Over-Ear Headphone.
a good headphone in less price. its better to buy this headphone rather than buying earphone. Comfortable to ears. awesome design and quality of voice/sound.
