I purchased this so my boyfriend and I would not have to share headphones on a long plane ride overseas in case we wanted to watch a movie. Would not recommend because it does not shave well. I wash and dry them regularly! Nice comfy fit So I’m gonna have to push that out myself to be able to use the keychain. no holes to drill, just let it hang under the console. Does not work with T-Mobile or Metro PCS. - The 20” USB-C charging cord is the new standard that’s smaller, carries higher voltage or data speed, and best of all is reversible (there’s no wrong way to insert it). BONUS: You get a free wristband and carrying pouch! I saw some reviews that said this was too short for someone around my size.
