What's in the Box
Comfortable to wear, robust bass, crisp treble, good battery duration.
Verwende den Kopfhörer mit einem kleinen MP3 Player im Studio.
Optimaler Sound, Kopfhörer stört beim Training überhaupt nicht.
Würde ich wieder kaufen.
Fantastic sound, Light and compact for travel
Sound quality is fine, charge time is fine, but I have some quality issues:
Left ear just simply stopped working. I've tried the very basic and difficult-to-find troubleshooting, the factory reset - it's just not working.
Quality is pretty basic, they're lightweight and not super strong.
Other than that I'm still looking for a Bluetooth headphone with controls that make sense. The "skip" function a spring-loaded sliding control, while volume up and down is a double-ended button. It means if anything brushes the headset, your media track skips. If the slider was the volume control, it may be slightly annoying to have the volume changed on you accidentally, but nowhere near as disruptive as having to go back to the previous track - and have it start all over again.
L and R are also very difficult to differentiate, and as I didn't use mine much before the left ear failed I could never remember which was which. There is an L and an R moulded into the inside of the headband edge, in matt ABS plastic which really is hard to spot. I appreciate they want a sleek look for the product, but surely this could have been done better.
But my biggest gripe is the left ear not working. My 12-month warranty was close to expiry and I was frustrated out of persisting with the warranty support because, like everyone, I'm busy. I feel that any large company whose support processes are slow and frustrating has structured them so deliberately. This is really poor.
A very good travel companion :)
