Usage Tips

• Pairing Instructions: Turn on Bluetooth on your device, press and hold the center Power / Multi-Function Button (MFB) on the neckband controller for 3–5 seconds until the LED flashes red and blue, then select Celebrat A2 in your device's Bluetooth list.
• Choosing the Right Ear Tip Size: The earphones include multiple sizes of soft silicone ear tips (S/M/L). Select the size that provides a snug, airtight seal in the ear canal to maximize bass response and passive noise isolation.
• Safe Charging Practices: Charge the earphones using a standard 5V / 1A or 500mA USB port (e.g., PC USB port or standard wall adapter). Avoid using ultra-fast charging power bricks (such as 33W–65W phone chargers) to prevent stressing the miniature internal Li-Po battery protection circuit.

  • Single Press MFB: Play / Pause music or Answer / End incoming call.
  • Long Press MFB (2 sec): Reject incoming call / Activate Voice Assistant.
  • Short Press +/- Buttons: Increase / Decrease volume.
  • Long Press +/- Buttons: Skip to next track / Return to previous track.
• Maintenance & Longevity: After heavy workouts, wipe off excess sweat from the ear tips, microphone opening, and silicone neckband with a dry microfiber cloth before storing or charging. Ensure the USB port rubber seal is fully closed during use.
