I need advise on MP3 players suitable to wear whilst running?

I used to have a small MP3 player that I could clip to my clothing when I went jogging. It was about the size of a small matchbox and weighed virtually nothing. I could upload songs to it from ITunes.
That is no long gone and I have been trying to find something similar but all I can find in the shops are devices that require a bluetooth connection to my Iphone and I do not want to take my phone jogging with me. Can anyone recommend something that works in the same was as my old MP3 player?

Here you go, it's inexpensive, it has a radio as well. The "operating system" sucks, it's really clunky, but it works and it is cheap and it does what it is supposed to do. I have one and while I certainly wouldn't say it's the best, I think you get your money's worth. My main issue is that navigation is rather inconvenient.

If you search for mp3 players I'm sure you will find more. I used to have the ZEN ones and liked them, but they have gotten way too expensive for what they offer.

Look at the SanDisk Sansa Clip Sport or Fiio M3. Both under $50.

The Sansa is available from most big box stores and the M3 from Amazon and B & H Photo.

There are plenty of iPod Nano models for sale online.

If CEX operates in your country then they're worth considering as they check their goods when buying them in and then offer a no quibble two year warranty on everything they sell. That's longer than Apple offered when they sold the Nano brand new.

I don't work for CEX but they have now become my automatic "go to" supplier for any secondhand tech because they fully support whatever they sell me.
