the instructions were a little vague. So I have speakers that can get loud and I know what an average BT speaker sounds like. I thought at first FINALLY a decent razor product. Says that they are water friendly but again they dont seem to like water as they have turned white. The three park system of locking, magnetic and strap work great (obviously, this is the holder and you still need the case) and feels very secure. I do not recommend it. Stretched out within a month of use. The sound on these is excellent. It plugs into a USB port and my computer found it easily and quickly downloaded the needed drivers so it was usable in about 15 seconds. - The lid cover sometimes comes off, which is understandable because theres not much surface area to keep it from doing so.
