I Just got the headphone, now burning it through cycles, but so far I am happy with the quality. There is high demand of C Type Headphones although very few good products available in market, thanks to wecool for bringing the product.
Sound Quality : Sound reach is high, highs are good, mediums are moderate, lows are better. Bass is boosted to some extenet, I cant hear over 60% of volume, distorts a bit over 90% volume.
Noise Cancellation : Although they didnt work much on noise cancellation, it is as good as a 50 Rs Headphone street vendors sell.
Build Quality : Wire quality is breaded wire, looks solid so far, does not tangle as expected, coated inside a sheet of plastic. Headpiece is of good shape, should not displace while jogging or running.
Verdict : So far for Under 700, Its as good as you can get here for a C Type Headphone with Mic, there are no better alternatives available so far.
