5.2 Pairing with a Device
- Power On: Open the lid of the charging case. The earbuds will automatically power on and enter pairing mode. The LED indicators on the earbuds will flash.
- Activate Bluetooth: On your smartphone or other Bluetooth-enabled device, go to the Bluetooth settings and turn on Bluetooth.
- Select Device: Look for 'HOCO EQ20' in the list of available devices and select it to connect.
- Confirmation: Once connected, you will hear an audible prompt, and the earbud indicators will stop flashing.
- Master-Slave Switching: The earbuds support master-slave switching, allowing either earbud to be used independently.
5.3 Wearing the Earbuds
Choose the ear tips that provide the most comfortable and secure fit for your ears. Insert the earbuds gently into your ear canal and twist slightly to ensure a snug fit. A proper seal is essential for optimal sound quality and noise cancellation performance.
6. Operating Instructions
6.1 Power On/Off
- Power On: Open the charging case lid. The earbuds will automatically power on.
- Power Off: Place the earbuds back into the charging case and close the lid. They will automatically power off and begin charging.
6.2 Active Noise Cancellation (ANC) & Environmental Noise Cancellation (ENC)
- ANC: Intelligently detects external noise and in-ear canal noise, emitting reverse sound waves for cancellation. This creates a quiet listening environment.
- ENC: Combined with a sound plus call noise reduction algorithm and a four-mic setup, ENC enhances call clarity by reducing ambient noise and wind interference during calls.
Refer to the touch control section for how to switch between ANC and normal modes.
6.3 Touch Controls
The HOCO EQ20 earbuds feature smart touch controls on the outer surface of each earbud. Specific functions may vary slightly depending on your device and application, but common controls include:
- Play/Pause: Single tap on either earbud.
- Next Track: Double tap on the right earbud.
- Previous Track: Double tap on the left earbud.
- Answer/End Call: Single tap on either earbud during an incoming call.
- Reject Call: Press and hold on either earbud during an incoming call.
- Volume Adjustment: Slide your fingertip up or down on the touch area of an earbud to adjust volume.
- Activate Voice Assistant (Siri): Triple tap on either earbud.
- Switch ANC/Normal Mode: Press and hold on either earbud for 2 seconds (cycle through ANC On, Normal). Note: A transparent mode is not explicitly listed as a feature for this model.
6.4 Dual Connection
The earbuds support connecting to two devices simultaneously. This allows you to seamlessly switch between audio sources, for example, listening to music on your tablet and answering a call on your phone without re-pairing.
7. Maintenance
7.1 Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.

- Do not use harsh chemicals or abrasive materials.
- Keep charging contacts on both earbuds and case clean and dry.
