Adept of the brand "Bose", I always a pleasure to discover its products. The sound is always excellent quality and bass are clear. Anyway, there is no possible settings except the sound. The device is compact, simple and the design is successful. The installation is extremely fast. The big downside is based on the connector compatible only with the latest version of Iphone and not with the majority of iPod. You just have to buy a specific cord a few euros but it could have predicted. Therefore recommend primarily for the latest versions of Iphone or Ipad.
