Really the best I've heard so far. Single Driver also has its advantages, which many indeed swear by multinationals. You must, however, get used to it as well as he really is. The ears are of different a bit "spoiled", so it takes time. But then you want to hardly hear with others! Too bad that the cables directly are not exchanged on the handset, but are good cable. Whether that is worth a price, you have to know just.
