Portable Bluetooth Speaker White Shark GBT-630 DAMARU White, wireless audio, built-in battery

White Shark GBT-630 DAMARU White is a portable Bluetooth speaker built for wireless audio playback from smartphones, tablets and other Bluetooth-enabled sources. The compact unit combines a balanced acoustic design with versatile connectivity options and a rechargeable battery, making it suitable for home use, travel and outdoor listening. With integrated RGB LED lighting and a mix of driver sizes, the DAMARU offers both visual and audio presence in a white MDF and ABS housing.

Advantages

The DAMARU delivers up to 30 W RMS output power and a 50 Hz – 20 kHz frequency response for clear, full-range sound. Dual-Core DSP processing together with Four-Way DRC reduces unwanted noise and helps maintain stable playback dynamics. Multiple input options — Bluetooth, AUX, USB, optical and MIC — and a Broadcast function for linking more than two speakers provide flexible connectivity for different setups. A built-in 7.4 V / 2000 mAh Li‑ion battery supports portable operation for up to 6 hours at 60% volume, while RGB LEDs add visual ambience.

Suitable for

• Casual music listening at home or in small outdoor gatherings
• Portable audio for travel and short trips
• Connecting to TVs or media players via optical or AUX inputs
• Using as a hands‑on speaker for mobile devices via Bluetooth or USB
• Temporary microphone input for announcements or karaoke

When it may not be suitable

This speaker is designed for small to medium-sized spaces; it may not provide sufficient output or low-end extension for very large outdoor events or professional live sound reinforcement. Battery runtime of up to 6 hours at 60% volume will vary with volume level and audio content, so extended off-grid use may require external power or more frequent recharging.

How to use

Charge the speaker fully before first use using the supplied charger or compatible USB power source. For wireless playback, enable Bluetooth on your device, search for and pair with the White Shark GBT-630 DAMARU within a range up to 10 metres. For wired connections, use the AUX, USB or optical inputs as required; connect a microphone to the MIC input for voice use. Adjust volume and playback using the device controls or the speaker’s onboard buttons. To expand sound coverage, enable the Broadcast function and follow pairing instructions to link multiple DAMARU speakers.

What to consider before purchase

• Intended use: suitable for small to medium rooms and portable listening, not for professional concert-level output
• Battery life: up to 6 hours at 60% volume — actual runtime depends on volume and source
• Connection needs: ensure required inputs (optical, AUX, USB, MIC) match your devices
• Placement: MDF + ABS housing offers durability but avoid prolonged exposure to moisture

Usage recommendations

For balanced sound, place the speaker on a stable surface at ear level and allow some distance from walls. Use the optical input for TV or media players when lower latency and cleaner digital audio are required. For longer outdoor use, keep a portable power bank with appropriate output to recharge the speaker when needed.
