2. Usage Features
3. Maintenance Features

The realme Buds Air 3 are wireless earbuds designed for a seamless audio experience, integrating various features for both functionality and user convenience. This manual provides detailed insights into the device's structure, usage, and maintenance, ensuring optimal performance and longevity.

Function Description

The realme Buds Air 3 consist of two main components: the earbuds themselves and a charging case. Each earbud is equipped with an indicator light, a key switch, and a battery. Internally, the earbuds feature a speaker, an FF MIC, a touch sensor, and an antenna for Bluetooth connectivity. The charging case, which houses the earbuds, includes a USB-C port for charging, a Hall sensor, and pogo pins for charging the earbuds. The ear detection sensors (S0 and S1) within the case and earbuds facilitate automatic playback control and other smart features. The mainboard manages all internal operations, while the charging pad ensures efficient power transfer to the earbuds.

The earbuds are designed for both audio playback and communication. The sound hole delivers audio, while the MIC hole captures voice for calls. The frustrated hole likely serves as a pressure equalization vent or an additional microphone opening. The indicator light on the charging case provides visual feedback on its status, such as battery level and pairing mode. The key switch on the charging case allows for various controls, including pairing and resetting.

Usage Features

The realme Buds Air 3 are designed for ease of use, with several features enhancing the user experience.

• Charging: The earbuds are charged by placing them into the charging case, where they connect via pogo pins. The charging case itself is charged via a USB-C cable. The indicator light on the case helps monitor the charging status.
• Pairing: To pair the earbuds with a device, the key switch on the charging case is used. Holding it down for a few seconds initiates pairing mode, indicated by a flashing white light. For detailed connection instructions, users should refer to the manual.
• Smart Controls: The earbuds incorporate touch sensors for controlling playback, calls, and other functions. In-ear detection automatically pauses music when an earbud is removed and resumes when it's reinserted. This feature can be enabled or disabled via the realme Link app.
• Noise Control: The earbuds offer noise reduction capabilities, including active noise cancellation (ANC), normal mode, and transparency mode. Users can switch between these modes by long-pressing an earbud, providing flexibility based on their environment.
• Communication: Equipped with microphones (FF MIC and FB MIC), the earbuds support hands-free calling. The MIC hole ensures clear voice capture during conversations.
• realme Link App Integration: The realme Link app enhances the functionality of the Buds Air 3, allowing users to customize settings, check battery levels, and perform firmware updates. The app also facilitates audio tuning and mode switching.
• Single Ear Use: The earbuds can be used individually, allowing for flexibility in different scenarios. The touch and ANC functions are partially available when using a single earbud.
• Troubleshooting: The manual outlines a comprehensive troubleshooting process for various issues, including cosmetic failures and functional problems. This includes steps for confirming the appearance of the charging box and earbuds, checking for foreign matter, corrosion, or damage, and testing specific functions like charging, key switch operation, and audio playback.

Maintenance Features

Proper maintenance is crucial for ensuring the longevity and optimal performance of the realme Buds Air 3. The manual provides specific guidelines and tools for cleaning and addressing common issues.

• Cleaning Tools: Recommended cleaning tools include tweezers, cotton swabs, an electric torch (or mobile phone flash), and ethyl alcohol. These tools are essential for removing foreign matter and dirt from various parts of the device.
• USB Interface Cleaning: If the USB-C interface of the charging box is blocked by foreign matter or dirt, users are advised to use tweezers and cotton swabs to clean it. If cleaning is difficult, alcohol can be used to assist. An electric light or mobile phone flash can help inspect the interface for cleanliness.
• Pogo Pin Cleaning: The pogo pins inside the charging case, which connect to the earbuds, should also be kept clean. Foreign matter or corrosion on the pogo pins can affect charging. Cotton swabs can be used to clean them, with alcohol as an aid if necessary.
• Earbud Cleaning: The SPK (speaker) hole, sound hole, frustrated hole, and MIC hole on the earbuds can accumulate foreign matter. Tweezers and cotton swabs are recommended for cleaning these areas.
• Liquid Exposure: In case of liquid ingress into the USB interface or earphone charging PAD, cotton swabs or tissue should be used to wipe the liquid. Alcohol can be used for difficult cleaning. If liquid cannot be removed, professional service is recommended.
• Addressing Rust and Corrosion: If the USB interface or charging PAD shows signs of rust or corrosion, cotton swabs and tissue can be used to gently wipe the affected areas. If the rust cannot be removed, the device should be sent for repair or replacement.
• Key Switch Maintenance: If the key switch on the charging box is jammed, tweezers or fine needles can be used to gently pry around it. If it remains stuck, professional service is advised.
• Responsibility Judgment: The manual emphasizes that many issues, such as foreign matter, rust, liquid damage, and physical damage (e.g., from dropping or external impact), are often due to improper usage and fall under customer responsibility. This distinction is important for determining repair or replacement eligibility.
• Regular Checks: Users are encouraged to regularly check the appearance of the charging box and earbuds for any signs of damage, foreign matter, or corrosion. Early detection can prevent more significant problems.
• Software Updates: Keeping the realme Link app and earbud firmware updated can help resolve software-related issues and improve overall performance.

By following these guidelines, users can ensure their realme Buds Air 3 remain in excellent condition, providing a reliable and enjoyable audio experience.
