When I have a $900 phone suspended in the air 6 feet up, its not coming out of my case! I could have ordered a small but I wanted to have a bit of room in the waist. Super easy install. Was den Langzeit Gebrauch betrifft , bleibt abzuwarten I would have. So, since I had only owned my speaker for two days and still had the receipt and box, I rushed back to BestBuy and scored the SoundLink Color TWO speaker. Also I have to return because it did not come with a Keychain as advertised. The only reason I had to return them was because of the size otherwise I love these Adidas sandals! Schneller, unkomplizierter Zusammenbau. They provide serious value-for-money and offer a listening experience that parallels — and in some way exceeds — anything offered by the more expensive luxury brands.
