I just bought two of these. Not for my iPod Shuffle. I don’t have one of those, stupid.
That is what they are designed for, but they will fit my no-name ebay special MP3 player from Hong Kong that Blugg bought for me. It has 1Gb on board, plays and records FM, MP3, Wavs and has a nice OLED display. Now I won’t have to worry about someone snatching it from my neck.
