Summary: The earphones have a good sound system, but they're built for people with above average ear size. Do not buy if you have small ears, as they are non adjustable. Otherwise a fairly good pair of earphones.
Summary: This earphone is great. The rubber supporting ledge turns according to your ear size. But i feel that its bass production is a little low as expected from me. Yet a handsome buy for me. I would recommend it!! Awesome packaging by AMAZON. Butter-like service from ordering to receiving!
Summary: This one turned out to be really good for jogging. No need to keep adjusting the headphone every now and then! But one should be lucky enough to an optimum pair of ears, not too small not too big!
Summary: Volume was quite impressive and sound quality above decent. I went for a 3 km run and not once did I have to readjust the ear phones. Sound quality is simply awesome!! At just 50% volume the quitest song that I have on my device was crystal clear. I can safely say close your eyes and buy it off. Worth every penny.
