This ear phone is just the right size to my ear, not tight and not loose, it feels so comfortable. sound quality does match it's price, i don't have too much expectations however sound quality still gives me some surprise. Noise cancelling is not very strong compare to bose, however when i turn it on in a air con room, i still can feel the difference when turn the noise cancelling on. Battery life is long enough for general use. Over all i quite like this ear phone, highly recommend!
