1. Initial Charging (5V / 3A Input)

Before first use, plug the provided Type-C USB cable into the speaker’s charging port and connect to a 5V 3A wall charger. The solid red LED indicates charging in progress. Once 100% full (approx. 3–4 hours), the red LED turns off. Warning: Do NOT use 9V or 12V fast chargers as excessive voltage will damage the internal battery.

2. Powering On & Bluetooth Pairing

Press and hold the Power button for 3 seconds to turn on the speaker. The LED indicator will rapidly blink white to signal pairing mode. On your smartphone/laptop, open Bluetooth settings, search for ‘Stone 1200 Pro’, and tap to connect. (If prompted for a PIN, enter 0000 or 1234).

3. Setting Up True Wireless Stereo (TWS Mode)

To link two Stone 1200 Pro speakers for 120W wireless dual stereo:
• Power on both Stone 1200 Pro speakers in Bluetooth mode (keep both uncoupled from the phone).
• On any ONE speaker (Primary), press and hold the Play/Pause button for 2 seconds until you hear a beep sound.
• Release the button and wait a few seconds while both units automatically bond.
• Now enable Bluetooth on your phone, search for ‘Stone 1200 Pro’, and connect. Audio will now play simultaneously in left-right stereo across both speakers.

4. Controlling 6 RGB Lighting Modes

Short press the Power button while playing music to cycle through 6 dynamic ambient RGB light rhythms, or toggle the lights off to conserve maximum battery life.

The 4800mAh battery charges fully in approximately 3 to 4 hours using a 5V / 3A Type-C charger. A solid red LED indicates charging, which turns off when complete.

No! Always ensure your adapter outputs 5V (3A or 2A). Using higher voltage fast-chargers (9V, 12V, 20V) can permanently burn the internal charging controller circuit.

1. Inspect the Type-C charging port for dust or lint.
2. Test with an alternate 5V USB-C cable and adapter.
3. Verify the red charging LED turns ON when connected.
4. Let the battery fully discharge until the speaker shuts off, then charge continuously for 4 hours uninterrupted.

1. Verify the LED indicator is blinking white (pairing mode).
2. Double press the ‘M’ (Mode) button to disconnect any previously connected device.
3. Ensure the speaker is within 10 meters of your smartphone without walls or metal obstructions.
4. If prompted for a passcode, enter 0000 or 1234.
5. Clear phone Bluetooth cache and restart both devices.

• AUX Mode: Insert a 3.5mm audio jack into the AUX port. Short press the ‘M’ button to toggle to AUX mode. (Note: Volume and track buttons operate from the connected source device in AUX mode).
• TF Card / USB Mode: Insert a MicroSD / TF card or USB flash drive loaded with MP3 audio files. The speaker automatically detects and starts playback.

Locate the pinhole Reset port on the connection panel. Insert a small pointed object (like a SIM ejector tool) and gently press the internal reset switch. The Bluetooth pairing history will be cleared and the speaker will restart to default settings.

1. Check if the speaker battery is low; low battery voltage can cause audio clipping and distortion.
2. Turn off custom equalizers or bass boosters on your phone media app.
3. If water splashes entered the speaker mesh, gently blow-dry the grille from a safe distance (do not use high heat).
