This helmet has many advantages as I have read on a lot of specialized sites. It is very good, but I have some regrets (at least with my Samsung Galaxy Note 2 and PowerAmp 2.0.9) that I have not detected in comparison (like what: Always try before): - The bass is really powerful despite what I read. Suddenly, the sound is very cashed see suffocated. To have a clear sound I had to make a particular setting on the equalizer: make a curve that the minimum share of almost 31 Hz to 16 KHz max through 0-250 Hz (shape of the curve as one draws the needle between 9:00 to 12:00)! This setting is nickel ready for just any style. - This is especially the volume control of the smartphone that has the effect; the volume provided by the helmet of control is almost imperceptible. This is a rather embarrassing. - To my ears it is a circum-aural headphones. This is the first time and I hate walking with: I mean my whole body vibrating when I move and it's worse when walking to each heel kick. So, this is a very good helmet sitting in the office, sitting in the tram, sitting in a park, sitting on the terrace, etc.
