Quality of sound is very good. But as a product on the whole it is not up to the mark. Within a month after purchasing it, right side speaker has become faulty. So this product now is useless for me. I am just using it as an antenna to hear a FM radio with loud speaker. Overheating is there after long use.Not Good for Outdoor because, it frequently fall from your ear. Sound quality is good.! Think before you purchase. Those who are want to Record there voice/Song Don’t Purchase. Mic is not working fine Create noise for conversation on earphone also problem
