I am in exactly the same situation as you - I got my 4th gen Shuffle yesterday (after my 2nd gen was accidently put in the laundry). The 2nd gen version was brilliant so I assumed the 4th gen would improve it even more, however the first time I plugged it into the cassette adapter in the car, I assumed it was defective. The background whistling and clicking between tracks ruins spoken word or quieter songs. It means its not really useable with a cassette adapter, which is a big let down, as thats the purpose I bought it for! I am going to see if I can send it back and get a 2nd gen from somewhere. I know cassette adapters are old tech, but its frustrating that a newer version of the Shuffle has this big issue with them, whereas an older model does not.

I bought a 4G shuffle in January which works fine with the provided earbuds. Today I tried using my higher end earphones and got the fairly loud sound (like am or shortwave radio background noise) that you both describe. To be thorough, I checked that they worked with my old MP3 player, and the shuffle sounded fine with the OEM earbuds. Since the noise is happening when the shuffle is connected to your cassette adapter too, I assume that the shuffle amplifier has a very limited impedance that it can tolerate - unless of course we all received bad product. I wonder if there are 4G shuffle users with success stories when connecting to other than "regular" earbuds.

I found the solution for the car adaptor:
