Overview
A clip-on 64GB MP3 player with Bluetooth 5.3, built for runners and gym use, with AUX and USB connections for car playback and phone file transfer over OTG.
Like the other budget players in this batch, its Bluetooth sends audio out to headphones or speakers but will not pair with a phone, computer or car head unit directly; car use instead runs through the AUX cable or USB plug. The clip and compact body point this one at active use rather than desk listening.
- FM radio and voice recorder included
- 64GB storage
- 20 hour battery from a 2 hour charge
- Volume limiter and line-in recording
Who it's for
Good for someone who wants a lightweight, clip-on player for runs or workouts and also plans to plug it into a car stereo via AUX or USB. Not the choice for anyone expecting to stream music to it wirelessly from a phone.
Pros and cons
- Clip design for running or workouts
- Works over AUX or USB in a car
- OTG file transfer from a phone
- Doubles as a USB flash drive
- Bluetooth cannot connect to phones, cars or computers
