I returned this item as it's much larger than the photo shows, it is also terrible to carry when it's not attached to a bike. So was a big no no for my commuting purposes. If your after a large bag for a weekend away, then this is probably a good option.
Amazing clarity for its size. Great battery life Don't expect full size speaker system quality! But if you're of the white headphone apple sound quality generation/ listening to music through your phones speakers and enjoying it - Then please, do me and everyone else around you a favour - buy one of these! Worth every penny
