Helmet "midrange" by its price, it beats some luxury in some areas.
particularly remarkable solidity, has more than a year that I lug around in the evening, not a twist, mas a false contact. APRS and have more impact on the cable market many times, it is always good (no, I'm not a bruuuute!)
the sound is more than adequate for the price. it's not a headphone on for monitoring, I use to mix (vinyl) and it suits me well trs.
isolation of the ears in a noisy environment is really good trs.
