I acquired a used Tecsun M-801 music player.
The good,
- Built-in FM antenna with decent reception.
- User replaceable 18650 battery.
- USB-C port supports changing and acting as a USB speakerphone.
- It can record audio into a TF card.
- The built-in mic can be used for answering phone calls via bluetooth.
- It exposes its battery level to phones through bluetooth.
The bad,
- The recorded audio is in MP2 format at 160 kbps instead of MP3.
- The only knob has two functions. I prefer a dedicated volume knob.
- The USB-C port is not implemented properly to work with USB-C adapters.
- No AM reception.
- The speaker has a noticeable noise floor.
- Volume is not synced to phone in bluetooth mode.
