Slides like butter. For those worried about the buds falling out I did a shake test and couldnt get it to open. Didnt have a headache at the end of the day and I had to reposition the band on top fewer times. When I first got it a couple months ago I clipped it to my pants at work and that was a big mistake. I suppose if you thought they clamped too tight you could try stretching them out, but I really dont think its necessary. I do voiceover work, commercials and more. i do believe after breaking them they could potentially be very comfortable. I bought this VANKYO set because my not even a year old GRDE one just doesnt seem to last longer than one hour, charge wise. That was a bad ass set up. These were more than perfect, looking stylish rather than like cheap rubber, matching the outfit, easily managing the terrain, and were comfortable all day.
