Purcahsed and placed on a brand new Smith Variant helmet size medium. The sound is O.K. attached to droid. The fit is poor at best. The straps on the helmet interfere with the earpieces. Secondary, the weight of the earpieces cause them to pull from the plastic helmet. At that point the straps hold it all onto the helmet. Old helmets used to have snaps, might be time to consider retro. The controls are a little hard to operate without practice, but in fairness I wear mittens. I can adequately operate them with practice, but a bit more relief seems like it would help a bit. Overall I'm satisfied, but I'm not sure I am for the currency I took from my wallet. My old helmet just had plug-n-play headphones with a microphone to the phone and I think for the money it worked almost better.
