Theyre nice and cozy just not much support or cushion for the bottom of your feel. I was able to order a size up and still adjust them to fit snug. Insert depth affects sound very little because of the new dynamic driver. It is very handy to have in my toolbox as I move around the house hanging things. However, one other minor downside is that without music with ANC these produce quite noticeable hiss with random spikes. They include ahandy L-wrench, but my little cordless drill was helpful - I recommend. Wish their product line was more extensive. I tried to find something less than great about these headphones and I guess the only things I can come up with are (nitpicky) that they have a vinyl head cushion which will eventually break down in time, and that they are slightly on the heavy side however they are not uncomfortably so. Superb little space saving device. Had a white pair of these exact headphones that lasted me four years before one of the buds finally started to give me the sound crackle.
