I have only bought the Walkman for swimming and pulled him after two tracks forever. Will my co-reviewer (s) already certified a faint sound in the dry, so it is completely useless in the water. I like listening to classical music and hip-hop. It may be that this is a strange mix, but neither one can enjoy underwater. First, the headphones continuously flutschen in normal swimming out of the ear. While efforts are being supplied various sizes, but I have all brought nothing. The sound is lifeless. In hip-hop it sounds as if you look at the tracks listen through grandma's old phone and you hear classical music as good as nothing. Sony seems to be concerned about your hearing, but the thing is so low in the water that it is not useful for me. Even on land the sound is very dull and largely free bass. On Smartphone I use Bose QC 25 and there really are dimensions in between. For 109 EUR, the quality is very modest. Anyone wanting to use it only as a headset for making calls like have fun with it. Oh yes, the control is not really suitable for sport and jogging despite ring is therefore not to be fun.
