Query: Not for Cyclists

Although this product may be suitable for joggers, it is terrible for cyclists. The least bit of air flow around these headphone earmuffs creates incredible background noise. Also, for any type of users, the earpiece covers are very flimsy. They come off constantly and are not very easy to reinstall. Bottom line is that I was so frustrated/disappointed with this product that I threw it away in disgust within just a few weeks of attempted use. The advertising photos showed the product being used by a cyclist... totally inappropriate and misleading.
