They become uncomfortable quickly, and because they sit ON the ears and not AROUND them, they dont mask background/ambient noise. Rad Rover Step Thru 1 fits nicely into this holder. I experiment with this headset using Alexa speaker playing music in the room I was sitting in while broadcasting on zoom. Very good price they sound really great MONSTER way better then beats.

I have several pair of Crocs flip flops and I love them!
