HolyHigh Bluetooth 4.0 FM Radio

This portable radio combines Bluetooth 4.0 streaming with FM reception in a compact painted-metal housing. It uses a 40 mm driver rated at 3 W to deliver 360-degree stereo surround sound. A built-in microphone enables hands-free calls when paired with compatible iOS or Android devices. The unit is designed for home, outdoor and travel use.

Suits listeners wanting wireless audio

Buyers who need longer playback than the stated 6-8 hours should consider alternatives. Those requiring a fully waterproof rating rather than slight water resistance may prefer a different model. Users needing multi-room synchronisation or app-based equalisation will not find those features here. The speaker covers core portable audio needs without extra smart functions.

1200 mAh 18650 battery with USB charging

The integrated 18650 cell provides 6-8 hours of playback and recharges in 2-3 hours via USB. Overcharge, over-discharge and double leakage protections are built in to extend cycle life and ensure safe operation. This single power specification determines whether the runtime matches your daily listening sessions.
