can you recommend an mp3 player?
Yes, I am using a SanDisk ClipSport MP3 Player

I’ve been using it for a year now, and I’ve recently run into the trouble of hearing only one side of the recording. And I think it’s because I’ve connected/disconnected the headphones so many times I have damaged the female connector in the device.
Other than that, it allows you to listen to FM radio as well.
I haven’t used an actual mp3 player in years. I just use my phone (Old Samsung Note 4), with a 128GB MicroSD card in it. It has more storage space than I’ll ever need and it’s always with me.
