this helmet is exactly what I was looking for, namely a compatible headset with several phones (iPhone 5 and Galaxy S4, on the latter the volume control is not available).
The sound quality is good (when the insulation is on), it can operate without battery / battery (I mean if we sound more battery / charge unlike QC15), insulation is surprising when one look at the size of the product (but I find it worse than my Bose QC15).
Cable / off remote control jack length is not super convenient, but otherwise I highly recommend this product, hard to be better insulated with intras!
The most significant, the small compact case comes with, thankfully given the price but still handy.
