Very good site but poor product
I have to say that the LDLC site and services are not to blame in the following review, but I must inform future buyers to avoid this headset at all costs!
It is very difficult to find a headset with micro sd and often the quality is lower but here the sound is more than mediocre, no bass, crackling ... It's very-lo-fi ! In addition to an ergonomics with strawberries (a long press to change music and a short one to increase the sound? Seriously?) I have one of the ear pads that spends its time detaching itself and is also extremely hard to put back in place (wondering how it can be removed in 3 seconds when it sometimes takes me several minutes to clip it into the groove that is supposed to be there).
In short, run away from this headset, if you're not absolutely looking for a micro SD card slot there are plenty of other choices, and if that's the case choose a more expensive one.
