It does drag somewhat and catches on the smallest indention or raised area. The sensor in the unit never indicated I had place it in my ear. The microphones pattern is cardioid, meaning you must speak close enough to the diaphragm at the front of the microphone. I put one on my laptop. They do run a tiny bit small for a men’s size but still an amazing slipper at a terrific price. くつ下なしではきついですが履き心地はソコソコのです。ただ今まで軽い靴を選んで履いていたので重さは気になりました。アウトドアをするならこれくらい頑丈なのがいいと思います。足のサイズが実寸23㎝ですが足の甲が高くて幅広なのでとりあえずW7を注文してみて履いてみたら良さそうだったので使ってます。 It was bugging me that the straps kept moving around and making irregular patterns so I took some black thread and quickly sewed them in place. I was concerned at first about the 280s since many reviews noted they have a decent clamping fit on the head. Put many miles on them and not a bit of stretch or shrinking. Good product for the money.
