The sound is really balanced, but the bass is almost non-existent at normal volume. If you do it louder, but the bass is progressively stronger. But sounds more like a kick bass. An app for headphones I'm going to certainly not install. The main cable is due to the fact that it was totally verknickt stuffed by the manufacturer in the package, not nice to look at and take a few days to get back to be reasonably straight. A pity, I find that there is no clip to the collar or fasten the cable so. It always dangling from the ears around or hooked into Jack zippers etc. Well, I found that 3 different sized ear adapters are. The change can also be very good. But I am not altogether thrilled for 9 but OK.
