How to Pair Two Headphones with Your Phone
- Ensure both earbuds and the charging case are fully charged before first use.
- Take both earbuds out of the charging case. They will power on and start pairing automatically. (If earbuds are not connected to your device for more than 5 minutes, they will turn off automatically. Press the MFB button for about 3 seconds to manually turn them on when prompted "Power on".)
- The indicator light of one earbud will flash white alternately, and the other earbud's light will slowly flash white when paired successfully.
- Enable Bluetooth pairing mode on your phone. Search and select "A90 Pro" to connect. You should hear a voice prompt "Connected" when wearing the earbuds.
- If the earbud indicator light is off, it means the phone is connected.
Automatic Connection: By default, the earbuds will connect to the last paired phone automatically when powered on.
Prompt:
- If you encounter pairing issues, place the earbuds back in the charging case and repeat the steps. Refer to the reset steps in the FAQ section for assistance.
- These earbuds can be used together or individually. To use a single earbud, simply take one out of the case and connect it to your phone. For dual mode, manually turn off one earbud or place it back in the charging case to use the other one alone.

Charging
Earbuds Charging
Earbuds charge when correctly placed in the charging slots with the lid closed. You can charge the case and earbuds simultaneously, or charge the case first, then the earbuds. While charging, the case's LED bar will blink. The charging stops automatically, and the earbud indicator light goes out when fully charged.
Case Charging
Use the included Type-C USB charging cable to charge the case directly. The digital display will flash and show the battery level in real time. When fully charged, the number will display 100.
Charging Alerts (!)
- After prolonged use, magnetic connector oxidation may prevent earbuds from charging or turning on. Clean the magnetic connectors on the earbuds and charging case with an alcohol wipe to resolve this.
Storage and Maintenance
- If earbuds have not been used for over 3 months, recharge them.
- Use an FCC-approved charger.
- Children aged 12 and under require adult supervision.
- Do not expose earbuds to extreme temperatures or use during thunderstorms.
- Avoid dropping or subjecting the device to strong impacts. Keep the device away from fire sources and do not immerse it in water.
Frequently Asked Questions
Q: Why won't these earbuds pair with my phone?
A: Ensure earbuds are fully charged and powered on. Verify your phone's Bluetooth is enabled. If issues persist, turn off earbuds after 5 quick clicks, place them in the charging case, close the lid, wait 1 minute, open the case, and reconnect.
Q: Why does the music cut in and out?
A: Maintain a distance of no more than 15m (without obstacles) between earbuds and phone. If the distance is less than 15m, place earbuds in the case, close the lid to disconnect from "A90 Pro" in phone's Bluetooth settings. After 10 seconds, open the case and reconnect.
Q: Why won't the earbuds charge or disconnect from the phone after placing them in the case and closing the lid?
A: Ensure the charging case has sufficient battery. If the case is low on battery, earbuds may not charge or disconnect. Use the Type-C cable to fully charge the case.
Q: Are these earbuds sweat- and water-resistant?
A: The earbuds are sweatproof and slightly water-resistant. However, for electronic devices, submerging them in water is not recommended.
