I dont find them ultra comfortable. On top of it, I am on my feet all day long. And when this case eventually gets worn out, I will buy another one. But, as with any ear bud, they may not fit your ear as well as mine. I bought that one and even though it was expensive, it was well worth the money. First, the quality of sound is mediocre at best. Its not perfect, but what is? For me, Im delighted I bought it & use it all the time. This knob is large and doesnt feel secure. Id rather the device doesnt adjust the audio at all. This is my second pair of Mandalyn Wedge Tevas.
