For the past 4 months I use these sports headphones while jogging. For my sports activities - run for 30 minutes - - two to four times per week 20 I'm very happy with the product. The sound is great, the headset sits firmly without pressing. I do not even notice it while jogging. The cable can be fixed so that it does not slackens. For me it was critical when buying that the in-ear KH my glasses "does not come into the enclosure". Had left me to the previous reviews, as this respect nothing concrete was on the Sennheiser website. Now I can confirm that he is truly ideal for eyeglass wearers. Thanks to the reviewers who have facilitated my decision to buy!
