Recently bought this Awei ES900i in ear phone from shopcludes.com. The sound quality is awesome with great bass, mids and highs. The mids are a little louder and had to adjust the equalizer a little bit and now its great. I have a JBL 33 model earphone as well as sony too. But Awei stands out in terms of sound quality.
Comes with an inbuilt mike also. Sensitivity is 110db +_ 3 db which is one of the most sensitive earphones out in the market. It makes very good bass, mids and highs. Even with my moto G mobile at low to mod volume I feel very satisfied.
