Just like a cheap chinese product this product also is of no use I have replaced this earphones with Audio Technica Ath clr 100 after using it for just two days. Battery is pathetic amd playback time is mere 2 hours which is too low for and also the sound quality is not at all satisfactory bass is no were close to any good quality earphones highs lacks clarity and I felt little bit of distortion at higher volume not at the highest but above 80% volume mids are okay but again for the price I think there are all better earphones in the market to go for. Also the build quality is not what I would have expected although its a wireless earphones but considering the drawbacks I think a wired one would be a much better option or invest more can go for a branded product
