Actually, I thought I had finally found the perfect KH go. Because the Sony is not too bulky and has a pleasant, not too bass-heavy sound. However, what all to nullify, is the cable: With every movement, which can strip the cable to something (shirt, jacket, whatever) is that to hear more than clear. You already dares no longer to move at all. Around with this KH, not at work! I tried it with alternative cables, but in vain. This design flaw in my opinion, inexcusable and makes, as I said, the other virtues of this KH completely destroyed. Very unfortunate.
