SHANLING M0s 1.7 * 1.7 inch 2in1 MP3 Player DAC Hi-Fi Sound Music Player Portable Digital Audio Player Support Up to 2TB SD Card HD Touch Screen Bluetooth5.0 3.5mm/Type-C Jack

I was looking for a music player to replace my 17 year old iPod Nano as the battery is no longer retaining its charge. I wanted something small & lightweight to listen to while running. This looked like a reasonable option.The “Getting Started” guide is basic and I couldn’t find an online manual specific to the M0s, so I ended up reviewing the online manual for the M0 Pro – the operation seems to be the same.Unfortunately, I struggled to insert the micro SD card. There was no click when pushing in the card and it just kept popping back out. Occasionally, it seemed to be in place but it wasn’t recognised by the device. I spent about 10 mins trying to insert it and I thought I might break the slot cover with my efforts. However, eventually it seemed sit correctly & the message “Card Inserted” appeared on the display.I copied my music files to the unit with it connected to my laptop with the USB cable, while keeping theMicro SD card inside. Took me about half an hour to copy all of my files to the card, then it took a couple of minutes for the unit to update & recognise the contents. I miss the auto synchronisation of playlists when syncing my old iPod via iTunes, but I got round this by creating folders and copying the files. I’ve ended up with multiple copies of some files in different folders, but that’s not a problem as there’s plenty of space on the memory card.The M0s paired ok with my Jabra Elite 7 and Sony WH-1000M5 headphones, with the Sonys connecting via LDAC. It plays all of my music file formats: WAV. Apple Lossless, AAC & MPEG.I’m happy with the sound quality – it’s as good as, if not better than my old iPod, especially when using the Sonys. I‘ve never had another digital audio player so that’s all I can compare it with.Overall, I’m happy with this player, as long as that music card stays in place.
