I used to love this company for its quality. To help I gave each one of them a good wrap of tennis grip tape and that works great for overcoming this. The smaller ones were better. Sometimes they tend to stretch depending on shoe style. Anyway, I had to return both sizes of the aubrey. Solid, simple, stable. These are awesome . this is for the red ?sweater? earpads and black/leather earpads replacements. They hold a phone microphone to my shirt and give way when I forget about them and pull off a sweatshirt. Pros:- clear, good quality sound- headphone wire is decently long- comfortable- stays in the ear for long periods of time- easily cleanedCons:- has a low electrical buzzing sound when the earbuds are plugged in but nothing is playing- is prone to collecting ear wax (but is easily cleaned)
