I buy these all the time, and they usually end up like this before I leave the parking lot of whatever electronics store I happened to be at. Why? Because most of these are so cheaply made that the rattling of the loosely fitted gears inside the cassette is louder than the music you’re playing!! It’s unbelievable. The last 4-5 I’ve purchased were like that, and my current option is on it’s way out. At this point, I’m willing to order several of the damn things at once from Amazon. I’ve also seen bluetooth tape deck adaptors, those could be built to an ever so slightly higher standard since they cost 2x as much as an aux cable unit.
