Translation: machine translated
- Good sound
- Very high wearing comfort
- waterproof (IPX5)
- Moderate battery life
- No app
- Only three rubber attachments
If it were only a question of sound, the Koss would come in third. The small earpieces sound somewhat cool, but very clean and do not annoy with booming bass. The other features are rather average, and the battery life is comparatively short at five and a half hours.
