Sound quality of cassette recorded in a studio. (For those who managed to get them).

For the rest ... good sound quality ...

Sound is great from the mobile. You can't tell the difference from a radio. Pleasant surprise that I found it because the car only had a cassette player! Sometimes (when it was very hot and after hours of driving if that matters) the machine would eject the cassette and it would do it every time I put it back in, but the cassette player does different things in general so I don't think it's the product's fault.

First of all, it is clearly the cheapest in its category. Apart from that, it did the job, although the sound quality was like that of a mobile phone speaker, even though I was using the car's sound system, which was good. I used it to listen to music from my phone and noticed that it had much better quality when I lowered the volume of the phone and increased the volume of the car's sound system. Overall, I don't think the sound quality is a matter of the adapter, I think it has to do with the nature of signal conversion, it is very likely that some frequencies are being cut with any adapter you use, so overall I am satisfied.

It works perfectly. Very good sound quality and also provides enough volume without distorting the sound too much.
