Unboxing
The EarFun Air Pro 4+ packaging takes a clean and informative approach that fits well within the true wireless earbuds segment. The front of the box features a clear product image that highlights the stem-style earbuds, with minimal branding and key audio features such as Premium Sound, LDAC, Hi-Res Audio Wireless, and Qualcomm aptX Adaptive. On the back, the focus shifts to practical specifications, including hybrid adaptive ANC, 10mm dynamic drivers, a six-microphone call system, multipoint connectivity, low-latency gaming mode, and rated battery life with the charging case.
Opening the box, the EarFun Air Pro 4+ sticks to a familiar and practical presentation. The yellow inner packaging keeps everything neatly arranged, with the charging case and earbuds placed securely at the top. Below that, a separate section holds the included accessories. Inside the box, EarFun provides the Air Pro 4+ earbuds, a compact charging case, a USB-C charging cable, and multiple pairs of silicone ear tips in different sizes for a better fit. Printed materials are also included, such as the user manual, quick start guide, and warranty card, covering all the essentials needed for initial setup and daily use.
Design and Build Quality
Charging Case Design
The EarFun Air Pro 4+ charging case is built with daily use in mind, focusing on portability and ease of handling. Its compact, rounded shape allows it to slide easily into a pocket or small bag without adding noticeable bulk. The curved edges make the case comfortable to hold, while the matte black surface keeps reflections low and helps reduce the appearance of fingerprints and light scratches over time. Visually, the design stays clean and restrained, fitting well within the wireless earbuds category.
The build feels reliable for a case made from plastic. There is enough rigidity to prevent flex during normal handling, and the panels fit together cleanly. The lid opens smoothly and closes with a firm snap, giving confidence in the hinge mechanism. Inside the case, the earbuds are guided into place by magnets that hold them securely and ensure consistent contact with the charging pins.
Externally, the case remains simple and functional. A small LED indicator on the front shows charging and battery status at a glance. The USB-C port is positioned at the bottom, allowing easy access when charging the case on a desk or bedside table. Overall, the charging case design prioritizes durability and convenience, which suits everyday use.
Earbuds Design
The EarFun Air Pro 4+ earbuds use a stem-style design that emphasizes comfort and stability. The rounded earbud housing sits naturally in the ear, helping reduce pressure during longer listening sessions. The stems are kept relatively short, which improves balance and prevents the earbuds from feeling heavy or loose, even when walking or commuting.
The finish combines glossy and matte surfaces, adding subtle contrast without drawing too much attention. Glossy areas give the earbuds a clean, modern look, while matte sections help with grip and limit visible smudges. The EarFun logo on the stem is small and understated, keeping the overall appearance tidy.
Design details are well integrated into the overall shape. Touch control areas are easy to locate by feel, and microphone openings are placed neatly without disrupting the clean lines. The angled nozzles and included silicone ear tips help create a secure seal, improving both comfort and passive noise isolation. In daily use, the earbud design feels practical and well-balanced, focusing on fit and usability rather than visual extras.
Features
Powered by Qualcomm’s QCC3091 SoC and Bluetooth 6.0, the EarFun Air Pro 4 Plus focuses on stable wireless performance across daily use. Connection remains consistent when switching between devices, watching videos, or taking calls, while support for Snapdragon Sound and aptX Lossless allows compatible phones to deliver higher audio quality with reduced latency. LE Audio and the LC3 codec further improve efficiency, helping maintain a reliable link while keeping power consumption in check. Features like Google Fast Pair and an ultra-low latency mode under 50ms make setup quick and improve sync during gaming and video playback.
Audio output is handled by a hybrid dual-driver system that pairs a 10mm composite dynamic driver with the FeatherBA™ balanced armature. This configuration separates low and high frequencies more effectively, resulting in controlled bass, clear mids, and detailed treble without harshness. An 11-degree driver alignment is used to reduce interference between the two drivers, improving overall coherence and instrument separation. With Hi-Res Audio certification and LDAC support, the earbuds can transmit more data than standard Bluetooth codecs, offering better detail and depth on supported devices while retaining SBC for broad compatibility.
Noise control and call quality are key areas of focus on the Air Pro 4 Plus. QuietSmart™ 3.0 adaptive hybrid active noise cancellation uses a six-microphone array to adjust suppression in real time, reducing up to 50dB of background noise, particularly in the midrange. The same microphone setup, combined with AI processing and cVc™ 8.0 technology, delivers clear voice pickup during calls, even outdoors. Wear detection automatically pauses playback when an earbud is removed, and the IP55 rating adds protection against dust and water, making the earbuds suitable for workouts, commuting, and regular outdoor use.
Pairing, Resetting, and Reconnecting Earbuds
Pairing the earbuds for the first time is simple and does not require any extra steps beyond the basics. After removing the insulating film from both earbuds, place them back into the charging case and close the lid briefly. Opening the lid again puts the earbuds into pairing mode automatically. At this point, enable Bluetooth on your phone, tablet, or computer and select the earbuds from the available devices list. Once paired, the earbuds reconnect on their own when the case is opened, making daily use hassle-free.
Connecting two Bluetooth devices at the same time is supported and works as expected. This can be done through the EarFun Audio app by enabling the dual device option in the connection settings. Manual pairing is also available for users who prefer not to install the app. After connecting to the first device, pressing and holding the case button for three seconds triggers pairing mode again, indicated by a blue LED flash. The second device can then be paired, after which the earbuds will automatically manage connections to both devices when they are within range.
Resetting the earbuds is useful if pairing issues occur or when switching to a new device. Both earbuds should be placed inside the charging case, followed by pressing and holding the button for ten seconds until the purple LED flashes rapidly. After removing the previous Bluetooth record from your device, turning Bluetooth back on allows the earbuds to re-enter pairing mode, shown by a slowly flashing blue LED. This reset process restores a stable connection and eliminates most common connectivity problems.
Touch Controls
In day-to-day use, the EarFun Air Pro 4+ earbuds are easy to manage thanks to responsive touch controls built into the stems. Taps and long-press gestures are recognized consistently, allowing quick access to volume adjustment, playback control, and switching between ANC and ambient sound modes. The default control scheme works well out of the box, while the EarFun app offers additional flexibility for users who want to remap gestures to better suit their listening preferences.
LED Indicator Guide
In everyday use, the EarFun earbuds rely on a clear LED indicator system on the charging case that makes pairing, charging, and battery status easy to understand without opening an app. A slow-flashing blue light signals pairing mode, while the LED turning off confirms a successful connection.
Battery levels are shown clearly, with green indicating roughly 30 to 100 percent charge, yellow suggesting a lower remaining level, and red warning when power drops below 10 percent. During charging, a red light shows the process is active, switching to green once the case is fully charged. A rapid purple flash is used for factory resets, which comes in handy when troubleshooting. These small visual cues improve day-to-day usability and reflect a design that focuses on clarity rather than added complexity.
Battery Life & Charging
Battery performance on the EarFun Air Pro 4+ is well-suited for everyday use, especially for users who keep their earbuds in for long stretches. With Active Noise Cancellation enabled, the earbuds deliver around 8 hours of continuous playback on a single charge, which places them comfortably within the expectations for this category. Switching ANC off extends listening time to roughly 12 hours, making them dependable for long office hours, travel, or extended music sessions without frequent interruptions.
The charging case plays a big role in overall endurance. When combined with the earbuds, total playback time reaches up to 54 hours, allowing multiple full recharges before the case itself needs to be plugged in. During hands-on use, the case provided consistent charging cycles, and idle battery drain was minimal. This means the earbuds are usually ready to go, even if they have been left unused for a short period.
Charging options are practical and easy to live with. The case uses a USB-C port for wired charging, ensuring compatibility with modern chargers and cables. Wireless charging support is also included, which adds convenience for users who already rely on Qi charging pads. Although exact fast-charging figures are not listed, short charging sessions were enough to restore several hours of playback, making the EarFun Air Pro 4+ a reliable choice for daily listening.
Earfun Audio APP
The EarFun Audio app enhances the overall experience of the EarFun Air Pro 4+ with a clean and easy-to-use interface. Pairing is quick, and the app provides a clear view of battery levels for both earbuds and the charging case, making daily use convenient and practical.
The app handles noise control effectively. Users can switch between Normal, Ambient Sound, and Noise Cancelling modes, with additional options for adaptive ANC, manual adjustment, and wind noise reduction. Mode changes are quick, and the controls are responsive, allowing easy tuning depending on the environment.
Customization options are extensive. Touch controls can be reassigned for each earbud, covering playback, volume, track navigation, and noise control. In-ear detection can be toggled on or off, with separate settings for auto-play/pause and automatic call answering. A low-latency Game Mode is available to reduce audio delay during gaming or video playback, although performance can vary by device.
The equalizer section is simple and effective, offering presets like Default, Rock, and Pop, along with a custom EQ for manual tuning. The app also includes AI Translation for real-time and face-to-face translation, expanding its use beyond music and calls.
Overall, the EarFun Audio app is reliable, well-organized, and functional. It focuses on usability and customization, complementing the EarFun Air Pro 4+ hardware and improving the day-to-day experience.
