The cables are at the volume control without strain relief, that is, they depend only on the extremely thin cables inside. Therefore, pluck them out very easily. Remedy: Cable careful when volume control pull apart (each 1-2 mm) and dripping with super glue. Then plug into it carefully, again, the 1-2 mm, so spread the adhesive. This will increase the service life probably criticized here. Adhering to this advice naturally happens at your own risk and presumably leads to the end of the warranty / guarantee. At this low price, however, it seems to me useful, you do not want to have so frequently to do with the warranty processing. (The KH themselves inside the way a knot in the cable, which is against tearing there. Even the cables are even more long !, thick and high quality, do not tie a knot.)
Otherwise, these are ideal for long KH soft wear, no hot ears, but no foreclosure for ambient noise. Compared this price range significantly better, high efficiency (louder than others) and the Micro is relatively large (also brings low frequencies, so one does not sound squeaky but sonorous course). Hence my CHEAP recommendation which justifies the low cost of eliminating the vulnerability. (Since it is not a cheap plastic dustbin Klump part up.)
