After watching about an hour of reviews for different phones, I ordered this one. The only difference is that these have an elastic opening and the other ones were just a loose top opening. Loved the rayon, haaaated the polyester. Great workout shoe and comfortable enough for wearing around the house all day. Oh, yeah - and theres a headphone jack built directly into the mic so you get absolutely no delay when recording :) This is one of those things thats so good you just buy it even if you dont need it. I have been using it for workout at home and its been a helping me grow my grip strength. The tracking and overall feel are good though, and the clicks are silent as advertised. Simple to install. Den Gesprächspartner hört man ohnehin einwandfrei aber auch am anderen Ende klingt es von der Qualität her wie direkt ins Smartphone gesprochen. ?????????????????????????????
