I have many such bluetooth headphones. The tailpipe is right under the drivers side of the hitch. Highs are terrible. The mounting part (that holds your phone) is made of plastic, for the price, I guess most of it went into the metal clamp that goes on the handlebars. But I will say these shoes are so stinkin adorable and cute! Almost a shoe. The earhook is also made out of soft silicone, so it doesnt hurt even after hours of wear. sound is good but the unit its self is low quality not worth 200. muscular. You can not even register them for the warranty as each time you enter the serial number and product number it says invalid
