Need to buy a few pairs now as my hub keeps trying to steal them. Now if I could only get him to drink enough water. (NOTE: my computer does not recognize the micro sd card when it is in the speaker. Easy to place and no issues with stability or strength. These headphones do a decent job reducing train & ambient noise but you can still hear the outside world (its a good amount quieter, but definitely still there). For the price, and for any price, I have to admit these Letscom headphones probably have the longest battery life of any headphones Ive personally come across, at this point I think its sorcery. Very comfortable and fits perfectly I am using it with a Pixel 4XL. I like the cushioned sole - when I switch to a classic boat shoe with a quarter inch rubber sole I really miss the pleasant feeling of these. The Gazelles themselves are really nice, they look clean and fresh.
