Avantree SP850 Portable FM Radio Bluetooth MP3 Player

The Avantree SP850 is a pocket-sized 3-in-1 audio player that combines FM radio, Bluetooth streaming and SD-card MP3 playback in a rechargeable handheld design.

This compact device delivers simple, on-the-go listening engineered for clear voice and balanced sound. Built with fast station access, a numeric keypad for presets, a headphone jack and a built-in rechargeable battery, the SP850 is designed for commuters, outdoors use, kitchens, workshops and anyone who needs straightforward audio without a large speaker footprint.

How does the SP850 let me listen to radio, music and podcasts?

The SP850 supports three listening modes: traditional FM radio, Bluetooth wireless streaming from a phone or tablet, and direct MP3 playback from a standard SD card. Switching modes is done with intuitive controls so you can move from live broadcasts to your saved tracks quickly.

• FM tuner with auto-scan and manual numeric entry for tuning stations.
• Bluetooth pairing for streaming apps, podcasts, and phone audio.
• SD card slot for MP3 playback without needing a separate device.
• Headphone jack for private listening and low-latency monitoring.

What sound quality and listening range should I expect?

Designed for personal and close-range listening, the SP850 emphasizes clarity of voice and balanced midrange rather than deep bass or high-volume room-filling sound. It performs best for talk radio, news, podcasts and background music in small spaces.

• Tuned driver for clear voice reproduction and even midrange response.
• Suitable for desktops, bedside tables, kitchens and small patios.
• Not intended as a primary speaker for large gatherings or high-SPL applications.

How easy is it to find and save radio stations?

Finding stations is quick with auto-scan or manual numeric tuning. The SP850 offers one-touch saving—hold any number key (1–9) to store a favorite and the display confirms "Channel Saved," so returning to a preferred station is instant.

• Auto-scan scans the FM band for active stations automatically.
• Numeric keys allow direct input of frequencies or preset slots.
• Hold-to-save function stores up to nine preset channels for fast recall.

What about battery life, charging and portability?

The unit includes a built-in rechargeable battery that charges over USB, making it convenient for travel and outdoor use. The replaceable battery design and compact dimensions mean you can slip it in a pocket or bag and top up power with common USB chargers or power banks.

• USB charging for easy power-up from common adapters and power banks.
• Compact, pocket-sized chassis for travel and handheld use.
• Replaceable battery option extends longevity and simplifies maintenance.

Who is this for: The Avantree SP850 suits listeners who want a lightweight, no-fuss audio companion for everyday life—commuters, hobbyists, kitchen cooks, workshop users and anyone needing a reliable radio plus Bluetooth/SD playback in a pocket-sized package. If you want crisp speech clarity, easy station access and flexible playback modes without the bulk of a full-size speaker, the SP850 is a practical choice.
