They have a usable sole unlike many others. It has no provision for wall/furniture mounting so I will try Velcro but I am not sure whether or not it will stay in place when pulling out a plug. I?m beyond mad about this especially because the controllers won?t even hold a charge. Although I still like it, after hearing the better sound signature of the XSound Go, including its much more substantial bass response, it now remains in storage. ComAmazing. We would like to inform you that the Beolit 20 was meant to be able to stereo pair with Beolit 17 but unfortunately, we are currently having issue having these 2 models paired together in the B&O app. Only because of someone in the Thule company doesnt care at all. I didnt need so many but couldnt beat the price. Ive used many BT wireless stereo headphones because Im fairly active in the gym and sweat destroys most headphones. I have 4 youngens, and only 1 of them is old enough to be out of diapers and in school.
