Good ratings lured me in. They are unrelated to any actual gadget. You can use it if you merely need background music and don't care about the quality. (However, I do not even suggest using "this" as the background.) Additionally, using a wire or more expensive Bluetooth with built-in DACs is preferable for listening in normal (in the original, lossless) quality. I bought this small gadget with the idea that it would be bearable, but it actually makes the sound nauseating in every manner, thus it was a waste of money.
