Setup
1. Charging the Earphones
Before first use, fully charge the earphones. The charging time is approximately 1.5 to 2 hours.

- The indicator light will show charging status (refer to the device's LED indicator guide for specific colors/patterns).
- Once fully charged, disconnect the cable.
Important: Ensure the charging cable is not bent or damaged. If the charging cable is exposed to strong corrosion or seawater, clean it immediately after contact. Always ensure the charger and charging cable interface are liquid-free before charging. Verify the charger has 3C and other security certifications, and that the power strip is grounded.
2. Powering On/Off
- To Power On: Press and hold the power button until the indicator light illuminates and you hear a power-on prompt.
- To Power Off: Press and hold the power button until the indicator light turns off and you hear a power-off prompt.
3. Bluetooth Pairing
The Sanag B33S uses Bluetooth 6.0 for wireless connection.
- Ensure the earphones are powered off.
- Press and hold the power button for approximately 5-7 seconds until the indicator light flashes rapidly (usually blue/red alternating), indicating pairing mode.
- On your mobile device, enable Bluetooth and search for available devices.
- Select "Sanag B33S" from the list of found devices.
- Once connected, the indicator light will change (e.g., slow blue flash) and you will hear a confirmation tone.
The Bluetooth 6.0 version introduces a channel detection function, with an error of less than 5m, allowing high-precision search for slot determination.

Operating Instructions
1. Switching Between Modes
The earphones support two primary modes: Swimming Mode (using built-in memory) and Bluetooth Mode (connected to a mobile phone).
- Swimming Mode: Utilizes the internal 32GB memory to play stored music. This mode is ideal for underwater activities as Bluetooth signals do not transmit effectively through water.
- Bluetooth Mode: Connects wirelessly to your smartphone or other Bluetooth-enabled devices for real-time audio streaming.
Refer to the device's control buttons for specific mode switching instructions. Typically, a dedicated button or a long press of a multi-function button will toggle between modes.

2. Music Playback
- Volume Control: Use the dedicated volume buttons (usually + and -) on the earphones to adjust the listening volume.
- Track Control: The control button allows for playing/pausing music and skipping tracks (e.g., single press for play/pause, double press for next track, triple press for previous track).
3. Call Handling
The earphones are equipped with a high-definition call noise reduction microphone.
- Answer/End Call: Press the multi-function button once to answer an incoming call or end an ongoing call.
- Reject Call: Press and hold the multi-function button for a few seconds to reject an incoming call.
