Damaged after less than 1 year, and I only used it occasionally. Also, I always stored it in the casing provided. There was totally no sound on the left tube, and overall sound quality is muffled and unclear. Unreliable product.

Excellent sound quality (i was quite surprised!). Granted, the sound delivery is not super high-fidelity, and unless you are accustomed to in-studio type headphones or ear buds, these perform very well. With that in mind, you absolutely must spend the time to achieve a proper fitment (or as other's have noted, they will fall out of your ears). The in-line controls are intuitive and easy to use, just be careful to not pull from your ear when adjusting them (if not using your device controls for functions). These are not anything like the conventional and EMF dangerous Apple or standard ear buds! Note to the lazy or convenience oriented users.... spend the time and follow the instructions included, or your experience will be less than favorable. Regarding physical activity usage (as opposed to static activity, such as reading or working at your desk), again, I highly recommend initial proper fitment (and they will stay inserted!), or wear something else without EMF protection, and potentially damage your brain. Edit 12/13/2025: Noticed other reviewers having issues wearing these while sleeping... what? You should never be listening to headsets while sleeping in bed (particularly with the typical wireless, or wired styles)! And wearing with a hoodie, of course there will be ergonomic complications rubbing the blue tubes, etc.) so it's not recommended to wear hoodies while using these.

tolles Headset mit super Soundqualität und verschiedenen Ohrpads. Super Verpackung. Die Preis ist etwas hoch, aber das nimmt man dann gern in Kauf.

I like these headphones (always use them when on the phone) so much I bought my son a pair for this birthday (I warned him about his bluetooth ear buds and how they fry your brain)!
