So happy with them ???? Didnt cost much to get caps off the shelf and in some order. While using it, I noticed some crackling as well. I?m running a commencal Meta AM with 160mmAnd it fits great. She wore them when she was pregnant and has been wearing Fit Flips as her running around shoes ever since. I own both the Airpod pro and Powerbeats pro, and the Soundcore 2 is a battery champ. If you can get these in the correct size, they are a great. I did add a nylon washer between the miter handle support washer and surface of the gauge. I also have some issues with bunions and they still fit well. For context, I always keep my headphones in my case and I never sleep in them.
