deleyCON Bluetooth In Ear Headset Earphone - [Black] - Stereo - for mobile, PC, Tablet, iPhone, Smartphone, Apple Mac (Electronics)
I use the headphones with a Samsung S4 while jogging or walking. My Samsung is in a leather sleeve and in the pocket or jacket pocket. Under these conditions, the connection is very, very often interrupted my Samsung S4. So the Kofhörer are useless.
