After reading many disheartening reviews about the sound quality and noise isolation being poor I was surprised at how wrong they are. Obviously the sound quality isn't as good as normal earphones of the same price the sound quality is noticeably better than other earphones I have used before. I have used these earphones whilst studying in a noisy room and was shocked that I couldn't hear anything apart from music which was at a low volume, the noise isolation is so versatile because of the 3 different settings and this is probably its best feature
