I have long compared the helmets because I was looking for a versatile max 150 euros. My criteria: good bass, good spatialization for games and TV, a detachable cable, the power facility for not low on his smartphone. We ended up advising me thereof; I had a doubt about the impedance that seemed high to me for use on smartphone. Appraisal: I TOTALLY SATISFIED with my purchase. This model has 3 more detachable cables (one short practice for smartphone player mode, but without microphones, one right and one 3m 3m twisted). The sound is as strong as on other mobile headsets (Philips M1 and others ...).
