I hear a lot of music in my free time and also when I'm on duty traveling by train. This means that sometimes I sometimes have the headphones up to five hours in the ear. In other headphones (including Sony, Samsung, etc.) I had an itch after a while and I did the OHRER from wearing the in-ears hurt. With this model, I can readily believe music enjoyment on all the time to enjoy without irgetwelche discomfort or inconvenience. The sound quality can be very difficult to describe in words, which is anyway in each case in the eye of the beholder, but with such a force and Dynamic I did not expect in-ear headphones, since some HiFi headphones for home stereo system do not come times With. I can only recommend this handset, because here price / performance ratio is more than given.
