I could not see myself in a helmet to 400.00. Around 35.00, it was perfect. Yet tjrs Sennheiser is very expensive (the famous microphones in live sound SKM 4031, SKM 5000, etc). Frankly, I do not regret at all, both aesthetically and acoustically. It is very nice (not overwhelming) to wear. The bass is really present, mediums too, the highs are also the RDV, accurate, non-aggressive (as at the time of the Pioneer headunit) but there. We are immediately charmed by its musical qualities. It folds into a nice little cover to the helmet color (black for black helmet, white for the white helmet because jen have actually bought 2, 1 B & B 1 2 children 1 boy & girl). So absolutely great, you can invest in this eyes closed!
