They are also extremely water proof and have good traction in the snow. The lids are a little hard to get on and off but they do the job. So when you move the drawer in/out, you have to tug it to angle it around the screw-heads. Needed single over the ear since by law around here you cant have both ears blocked while driving. Not sure if Ill continue to buy them in the future. Even with no sound playing at all it drowns out white noise and background sounds by about 60-70%, and with anything playing it drowns it out the rest of the way. It has a shockingly poor fit leaving gaps which cause its operation to be hindered. The interface is USB-C which makes it convenient. The entire time I put it together I literally thought, "All these reviewers are crazy, this is junk, how can anyone think this is any good". I love this mouse but the reason I gave it 3 stars is because the grip sides is not detachable and it does not have the option to customize I have big hands my pinky is always struggling because of the right wing (I know its there to help with the gyro angle) but come on you could easily make this happen.
