This cassette adapter is for people who are nostalgic for the past, such as having a player app on their phone that shows the cassette on the screen. It can be used either in a car cassette recorder or in a tape recorder, or, if there is no player at hand, to use it alone and to listen to music through a headphone or portable speaker. The latter must be connected by a cable as the cassette adapter does not have Bluetooth. The cassette adapter has a mechanical system that mimics the winding tape. However, the system produces noise that is well audible when listening to music quietly. I bought two cassette adapters at different times and both have this drawback. To reduce the noise, I had to disassemble the cassette adapter and remove a couple of gears.
