They are so transparent that it looks as if it is not even there. I had no problem figuring out how to assign buttons, its that they wouldnt work, or would start doing something else when games were up. Not a big deal, just corrected them with the right size bit. He said why he did not think about getting wireless earphones before. that?s why I bought 2! Not sure of the battery life yet since he?s only used a few times but overall a fantastic product at a fantastic price! they are not wide enough to sit over the rails, the cutout is to deep, and the bolt holes are extremely far apart. No good. I have sore feet and I can walk round town in these no problem! Easy to load and secure to the vehicle and had no issues at high speeds.
