RUIZU 64GB Bluetooth MP3 Player

RUIZU 64GB Bluetooth 5.3 USB MP3 Player is a compact clip-style music player that stores large music libraries, streams to Bluetooth headphones, and doubles as a USB stick and FM/voice recorder.

This lightweight RUIZU player combines a traditional MP3 stick, modern Bluetooth 5.3 wireless, and physical controls into one pocketable device designed for active use. It holds up to 64GB of files, supports popular audio formats, and offers up to around 20 hours of playback on a single charge. Its clip design and multiple connectivity options — USB, 3.5mm AUX, line-in, and OTG file transfer — make it suitable for workouts, commuting, and situations where a phone-less music source is preferred.

How does the RUIZU player connect to my headphones and speakers?

The player uses Bluetooth 5.3 for wireless audio to headphones and speakers, providing quick pairing and more stable connections than older Bluetooth versions. Note the Bluetooth function is intended for audio output only and does not pair with computers, cars, or smartphones for file transfer.

• Bluetooth 5.3 for low-latency, stable streaming to headphones and Bluetooth speakers.
• 3.5mm AUX jack for wired headphones or direct car audio connections.
• Standard USB plug for direct audio output to USB-capable car ports or file transfer to computers.

What audio formats and playback modes does it support?

RUIZU supports a wide range of formats so you can keep your original audio quality and playlists intact. It also offers multiple play modes and an equalizer for tailoring playback to your routine or preferences.

• Compatible formats: MP3, WMA, APE, FLAC, WAV, DRM, ACELP and OGG for broad compatibility.
• Playback modes: shuffle, playlist loop, sequential, folder repeat and more.
• On-device EQ, resume playback, bookmarks and folder-based navigation to manage libraries quickly.

How do file transfer and storage work with phones and computers?

File exchange is straightforward: plug the player into a computer via its built-in USB plug or use OTG to copy files from a compatible smartphone. With 64GB storage, you can carry thousands of songs, and the device functions as a regular flash drive when connected.

• Built-in USB plug for fast transfers to macOS/Windows computers.
• OTG support for direct phone-to-player transfers (requires OTG cable and phone OTG support).
• Advice: transfer in batches under 1GB for reliable copying and indexing.

What extra features help during workouts or travel?

Beyond playback, the RUIZU player includes practical tools for active lifestyles: a secure clothing clip, FM radio, voice recorder, line-in recording, and long battery life for extended outings. It’s built to be used hands-free while running, cycling, or commuting.

• Clip-on design keeps the player attached to clothing or bags for exercise convenience.
• FM radio and voice recorder for quick capture of ideas or listening to live broadcasts.
• Line-in recording records from other audio sources directly onto the device.
• Rechargeable battery provides up to about 20 hours playback after ~2 hours charging.

It's ideal for runners, gym users, older adults who prefer simple controls, commuters who need reliable car or AUX playback, and anyone who wants an affordable HiFi-capable player with large onboard storage and voice/FM features.
