Yes, it's true, it really means nothing that happens around when you turn it on system (except my Dyson vacuum but it is the old version of the ultra-noisy vacuum cleaner). Otherwise, the sound is honest but singularly lacking in bass, they seem muted but I am no expert in the matter. It holds in place, fits every head without one takes five minutes to set it, and without being lightweight, is bearable several hours on end. The headphones include hot though, it can may seem a detail, but it is not very pleasant in the long run. In summary, friendly headset that really helps to isolate ranks and transported easily in his rather small rigid hull, and the sound is good.
