How to Turn Off Heyday Earbuds

How to Pair Heyday TT2107 Earbuds

The Bluetooth name shown by these earbuds is HEYDAY EARBUD 04.

To pair them:

1. Remove both earbuds from the charging case to power them on.
2. Open Bluetooth settings on the phone or other device.
3. Look for HEYDAY EARBUD 04.
4. Select it to begin pairing.
5. Watch the LEDs for connection status.

Pairing Light Meanings

During Bluetooth pairing:

• The right earbud rapidly flashes white and red while attempting to connect.
• The left earbud shows a steady white light when pairing succeeds.

This red/white flashing state is related to Bluetooth pairing and should not be confused with the steady red light shown while an earbud is charging.

Earbud Controls

The TT2107 uses multifunction buttons on both earbuds.

Music Controls

How to Skip Songs

To skip to the next song, double-press the right earbud.

To return to the previous song, double-press the left earbud.

Mono Mode

The right earbud acts as the default earbud.

The manual states that the left earbud cannot be used by itself in mono mode.

Phone Call Controls

When a call comes in, the left earbud flashes white.

Music automatically pauses during a phone call and resumes when the call ends.

Voice Assistant / Siri Control

Press and hold either earbud for approximately 1.5 seconds to enable or disable the connected device’s voice assistant or Siri function.

During an incoming phone call, the same 1.5-second hold is used to reject the call.

Charging the Heyday Earbuds

The earbuds should be fully charged before first use.

A full earbud charge takes approximately 1.5 hours.

To charge the earbuds:

1. Place the left earbud into its corresponding slot in the charging case.
2. Place the right earbud into its corresponding slot.
3. Make sure both earbuds are seated correctly.
4. Leave them in the case until charging is complete.

Heyday Earbuds Red Light Meaning

A steady red light on an earbud means it is charging.

When charging finishes, the indicator changes state. The guide explains that charging is complete when the red charging light turns off and also describes the fully charged earbuds as showing white in the case.

So a steady red light while an earbud is sitting in the charging case normally indicates an active charging cycle.

Charging the Case

The case uses the included USB-C cable.

To recharge it:

1. Insert the USB-C end of the cable into the case.
2. Connect the USB end to a DC 5V USB power supply.
3. Allow approximately 1.5 hours for a full charge.
4. Watch the case’s white indicators for charging progress.

The regulatory information lists the device input as 5V, maximum 1A.

Charging Case Light Meanings

The charging case uses four white LEDs to show its approximate battery level.

The white LEDs flash while the case itself is charging. When the case reaches a full charge, all four LEDs remain steady white.

How to Reset Heyday TT2107 Earbuds

The charging case has a dedicated Reset button.

To reset the earbuds:

1. Put both earbuds inside the charging case.
2. Press the Reset button on the case.
3. Continue the reset process for approximately 6 seconds.
4. The earbuds will turn on and then off again.
5. This power cycle confirms the reset.

Resetting can be useful when the earbuds are behaving incorrectly or having connection problems.

Automatic Power-Off

The earbuds automatically turn off if they are not used for more than 5 minutes.

They can also power down after a lost Bluetooth connection:

1. If the earbuds move more than approximately 10 meters from the connected device, the Bluetooth connection disconnects and a prompt sound is heard.
2. If the connection is not restored within 2 minutes, the earbuds automatically turn off.

Bluetooth Connection Range

The manual uses 10 meters as the distance at which a Bluetooth connection may be lost.

Moving beyond that range causes a disconnection prompt. If the earbuds do not reconnect within two minutes, they turn off automatically.

Troubleshooting

Earbuds Are Not Working Correctly

Turn the earbuds off and then back on.

A basic power cycle is the first troubleshooting action recommended in the guide.

Heyday Earbuds Won’t Turn On

Recharge the earbuds, then try turning them on again.

When they are outside the case and powered off, press and hold both earbuds for approximately 1.5 seconds to turn them on manually.

Heyday Earbuds Won’t Charge

Check the charging case first.

If the charging case battery is empty, it cannot recharge the earbuds. Recharge the case and then place the earbuds back inside.

Charging Case Won’t Charge

Check that:

• The USB power supply is suitable.
• The power source is operating correctly.
• The charging cable or supply is not damaged.

The troubleshooting section specifies a 5V, greater-than-1A supply for this check, while the device marking lists a maximum input of 5V/1A. Owners should follow the rating printed on the product and use compatible USB charging equipment.

Earbuds Have No Sound

Increase the audio volume.

If there is still no sound, check whether the earbuds are connected to another Bluetooth device.

Heyday Earbuds Do Not Appear in the Bluetooth Device List

The earbuds may already be paired to another device.

If so:

1. Unpair them from the other device.
2. Return to Bluetooth settings on the desired phone or device.
3. Pair with HEYDAY EARBUD 04 again.

Device Asks for a Bluetooth Pairing Code

The earbuds normally do not require a pairing code.

If a code prompt appears:

1. Confirm that HEYDAY EARBUD 04 is the correct Bluetooth device.
2. Forget the device in Bluetooth settings.
3. Pair it again.
4. If the prompt still appears, enter 0000.

Earbuds Keep Disconnecting

Keep the earbuds within approximately 10 meters of the connected device.

If the connection is lost and not restored within two minutes, the earbuds shut down automatically.

• Use a soft, dry cloth to clean the earbuds and case.
• Do not use chemical detergents.
• Do not modify or repair the device.
• Keep the earbuds away from water sources.
• Do not use them in high temperatures or extreme weather.

When using the earbuds for phone calls, the guide recommends keeping approximately 5–10 inches between the microphone and mouth.
