I bought these because of the reviews it had and the specs. The audio balance itself is woderful and I have no complaints of the audio quality but I have to turn up the volume on my phone to nearly full to get a good sound out of it but yet with my Sennheiser cx 685 sports earphones I can get better volume and the audio itself is better than these and it's a sports earphone!! Another problem is that with the massive range of earbuds (which I admit is great) it comes with, not a single one fit comfortably in my ear; they kept falling out by me just walking at a gentle pace and my ear canal was in pain with some of them. I had to switch to my older buds (not from my Sennheisers). There is near no sound isolation in these no matter how loud my music is but that's probably because they don't fit properly in my ear in the first place. The design is good though: the colours are mellow so don't strike the eyes and the has a flexible rubber coating which makes it sturdy and look nicer as well. However, I've given up on these earphones and I'm going to buy another one. I can tell these are good earphones but just weren't for me.
