The earphones work with me on Android phone (Nexus 4) and Music Player (Cowon D2 +) as well as on a laptop with no problems. The speech intelligibility is very good for the other person, and even on the bike! One does not keep his mouth what you have liked to see in the micro fuzos :)
The cable could MMN. be a bit stiffer, and I am afraid that the abrupt transition at the plug will soon lead there to a cable break. I am curious to see if a replacement will be truly possible. Currently after about 2 weeks but no problems!
The accessories including a really protective bag makes me happy and well above average.
The driver is relatively long, which corresponds to a richer, fuller sound helps, but because it is of course also quite far out from the ear. But I'll be well with it, but this one star deduction.
