PROS: The inline remote control works perfectly on an Android phone, and they lock into your ear as advertised and are quite comfortable. CONS: The sound - I tried them on multiple Galaxy S phones and a laptop, and in all instances the audio was completely lacking of any bass whatsoever. I mean like nothing, no bass, like Panasonic just forgot to build it in. RECOMMENDATION: Avoid these like the plague, the worst earphones I have ever purchased.
