1. Quick Reference Table

2. Headphone Won't Turn On

1. Long-press the Power Button — a short press won't switch it on.
2. Connect the supplied USB-C cable to charge; a full charge takes 3–4 hours.
3. Watch the charging LED while charging: solid red means it's charging, off means fully charged. If there's no LED activity at all on a known-working charger and cable, this points to a hardware fault — contact support.
4. Note that the headphones are not designed to be used while charging — if they seem unresponsive with the cable plugged in, unplug it first.

3. Pairing Issues

1. Long-press the Power Button — on first-time use, or whenever powered on, it should automatically enter Pairing Mode with the LED flashing red and blue.
2. On your phone or laptop, open Bluetooth settings, search for available devices, and select "Muffs A3" from the list.
3. Once connected, the flashing lights will stop and the LED turns solid blue.
4. Stay within the 10-meter working range of the source device — walls and interference can reduce reliable range.
5. If the connection still fails, toggle Bluetooth OFF/ON on your device and try pairing again.

4. No Sound or Poor Audio Quality

1. Confirm the LED shows solid blue (connected), not off (powered down) or flashing (pairing mode/low battery).
2. Increase the volume with a single press of "+".
3. On your phone or laptop, check that Muffs A3 is selected as the active audio output device.
4. If audio still isn't playing, toggle Bluetooth OFF/ON on the source device and reconnect.

5. Call & Microphone Issues

Use the Multi-Function Button and Microphone Mute Button with the correct press type:

If the other party can't hear you clearly:

• Check the Microphone Mute Button's LED — a red light means the mic is muted; press once to unmute.
• Adjust the flexible boom mic so it's positioned closer to your mouth for clearer voice pickup.
• Stay within the 10-meter Bluetooth range of your phone.

6. Battery Draining Faster Than Expected

• Confirm you're charging with the supplied USB-C cable — a full charge should take 3–4 hours.
• Working time of up to 50 hours assumes moderate use; frequent calls, higher volumes, or leaving the mic active can reduce battery life.
• If battery life has dropped noticeably compared to when new, this is typically normal battery aging over time.

7. General Care & Safety

• Do not use the headphones while charging.
• Keep the headphones away from water and extreme heat.
• Clean with a soft, dry cloth only — avoid liquid or abrasive cleaners.
