RUIZU 64GB Bluetooth 5.3 MP3 Player – 80H Playback

This compact player combines a 1.8-inch display and a lightweight ABS shell with modern connectivity. It holds 64GB of built-in storage and accepts an extra microSD card to increase capacity, plays many audio formats natively, and streams wirelessly to Bluetooth headphones and speakers using Bluetooth 5.3. Designed for sports, travel, and everyday listening, it also includes extras like an FM tuner, pedometer, and simple photo/video viewing.

How long will the battery and storage last on a single charge?

The RUIZU MP3 player delivers up to about 80 hours of audio playback on a full charge and refuels quickly via USB-C in roughly two hours. Built-in 64GB memory stores thousands of songs, and you can add a microSD card up to 128GB (card sold separately) for far more capacity.

• Up to 80 hours continuous playback per full charge
• Fast recharging: ~2 hours with USB-C cable
• 64GB internal storage + support for up to 128GB microSD
• Drag-and-drop file transfer from a computer — no special software

What audio formats and sound quality can I expect?

This player uses a modern DAC decoder chip to reproduce a balanced soundstage with clear highs, defined mids, and solid bass for compact hardware. It supports a wide range of audio files so you can keep both lossy and lossless libraries on the device.

• Supported formats: MP3, WMA, APE, FLAC, WAV, DRM, ACELP, OGG
• HiFi-oriented DAC for improved clarity and detail
• Wired connection via headphone jack or AUX for car playback
• Bluetooth 5.3 for stable wireless listening to headphones/speakers

How easy is it to carry and control during exercise or travel?

Weighing only about 0.055 lb and sized around a 1.8-inch screen, the player slips into a pocket, armband, or small bag without adding bulk. The interface is simple to navigate, and the device includes practical tools for active use and daily convenience.

• Lightweight ABS casing for durability and comfort
• Pedometer, stopwatch, alarm, and calendar for activity tracking and routines
• Voice recorder and FM radio for hands-free notes and live stations
• Resume playback, A-B repeat, and folder-based file navigation

Can I use Bluetooth for file transfers or only audio streaming?

Bluetooth 5.3 on this RUIZU player is dedicated to audio output only — pairing with headphones and speakers. File transfer to the player is handled over USB when connected to a computer, using a straightforward drag-and-drop method.

• Bluetooth 5.3: audio output to headphones and speakers only
• Use USB-C cable to copy music, videos, and photos from a computer
• MicroSD slot for adding more storage; card not included

Who is this for? The RUIZU 64GB MP3 player is aimed at listeners who want a dedicated music device separate from their phone: people who exercise, commute, or prefer offline libraries and long battery life. It's also suited for kids, seniors, and travelers who appreciate simple controls, FM radio, and extra features like voice recording and picture viewing. If you want a compact player with modern Bluetooth, broad format support, and expandable storage, this model is a practical, affordable option.
