The sound of these earphones is balanced and detailed, with no enhancements on the bass. There is an app to personalise the listening experience, recieved faster than http://drop.combut I felt only a slight difference after using the personalised settings (got more out of the in-app equaliser, it has 5 different options).
Some wireless earbuds have a sort of annoying white noise, but these are reassuringly quiet when no sound is being played.
