    I've had it for 4 months and I've had no problems with it. Dropped it a couple times with no issues as well.


  • Not very "fun" to listen to, but not very bad either.

    Bought these on sale a bout a year ago. The headphones sound very flat, but that's the thing. For a lot of people, these headphones will sound pretty boring due to nothing in the sound really standing out. The Highs and the Mids kind of blend together, and the bass, while a bit punchy and not very muddy, isn't the most satisfying thing in the world. It doesn't help that these headphones don't seem to sound very clear to me, and that's when running it in wireless on the aptX codec, not SBC. When running these cans wired, they sound pretty good. The sound is a lot clearer, the bass and the vocals being the most obvious, and the Highs and Mids are easier to distinguish from each other. That being said, no one's gonna be buying these to use them wired. These headphones would probably be a boon to people that want a fairly balanced sound, however. For the average consumer, there are tons of other options out there that provide a more satisfying listening experience for the price. TLDR; If you like a "flat" signature with a bit of low end, these will be for you. for everyone else, get outta here.


  • Great Over-Ear Headphones

    I really like the simplicity of this headset. It feels durable as well. It has really clear sound quality for it's price point. Music sounds more "open" compared to other bluetooth headsets I've tried! What's really nice: Sound Quality, Microphone, Aptx (great for watching Youtube without lag), Comfy earpads (for me, some people think they're too small though), replaceable parts, sleek & low profile (easy to wear a hood over), Wired Option, Battery Life. You can tell this was designed in Germany. Ridiculous value!
