1. Design and Build Quality
Both earbuds use a compact, stem-style design intended for everyday use. Their charging cases are portable enough for a backpack, jacket pocket, or work bag, making either model suitable for commuting, travel, and casual listening.
The Air Pro 4 focuses on delivering practical functionality without unnecessary complexity. Its lightweight construction and multiple ear-tip sizes help users find a comfortable fit, although individual ear shapes will influence the final result.
The Air Pro 4+ retains the familiar in-ear concept while updating aspects of its case design and internal hardware. The changes make it an evolution of the original rather than an entirely different product.
For everyday use, neither model has a decisive design advantage for everyone. Fit, seal, and comfort depend heavily on your ears. If possible, test the included ear tips and ensure the earbuds remain secure when you walk or move your head.
Winner: Tie for general design; Air Pro 4+ for its newer hardware package.
2. Sound Quality and Driver Technology
Sound quality is the most interesting part of the EarFun Air Pro 4 vs 4+ comparison.
The original Air Pro 4 uses a 10mm composite dynamic driver in each earbud. This design reproduces bass, midrange, and treble through a single driver, providing a familiar sound signature suitable for pop, hip-hop, electronic music, podcasts, and general listening.
Its dynamic drivers can deliver satisfying bass without requiring expensive hardware. Through the companion app, users can also adjust the equalizer to emphasize vocals, reduce excessive bass, or create a personalized listening profile.
The Air Pro 4+ takes a different approach by combining a 10mm dynamic driver with a FeatherBA balanced armature driver. The dynamic driver handles the lower frequencies and much of the midrange, while the balanced armature is intended to improve high-frequency reproduction.
This hybrid design gives the Plus model greater potential for separating different musical elements. Cymbals, string instruments, background details, and vocal textures may sound more defined when the recording and listening conditions allow the extra driver to make a difference. Independent reviews have highlighted the Plus model’s detailed presentation and well-defined bass, although its sound is not universally considered class-leading.
However, two drivers do not automatically guarantee better sound. Tuning, distortion, ear-tip fit, recording quality, and personal preference are equally important.
For bass-heavy music, the original Air Pro 4 may already provide everything you need. For listeners who prioritize detail and enjoy experimenting with different genres, the Air Pro 4+ is the more interesting option.
Winner: EarFun Air Pro 4+ for its more sophisticated driver configuration.
3. Active Noise Cancellation (ANC)
Both models advertise adaptive noise cancellation with a maximum reduction figure of up to 50dB. That figure should not be interpreted as a guarantee that every sound around you will become 50dB quieter. Real-world performance depends on frequency, fit, environmental noise, and the way the measurement is made.
The original Air Pro 4 is well equipped for everyday noise reduction. ANC can help reduce the low-frequency rumble of buses, trains, air conditioners, and office equipment. It can make listening more comfortable without forcing you to increase the volume to compete with background noise.
The Air Pro 4+ also offers adaptive ANC and different noise-control options. Its updated hardware does not automatically mean that it will dramatically outperform the original in every environment.
Both models struggle more with irregular sounds such as nearby conversations, sudden announcements, and sharp noises than with consistent low-frequency rumble. This is normal for wireless earbuds, particularly at affordable prices.
The seal created by the silicone ear tips matters enormously. A poor fit can allow outside noise to enter and reduce the effectiveness of ANC, regardless of the advertised specification.
If you mainly want to block traffic noise during your commute or reduce distractions while studying, either model should be worth considering. Do not pay extra for the Plus version solely because you expect a massive improvement in noise cancellation.
Winner: Close contest. Choose based on price and fit rather than the maximum advertised ANC figure.
4. Bluetooth Connectivity and Codecs
The standard Air Pro 4 uses Bluetooth 5.4, while the Air Pro 4+ upgrades to Bluetooth 6.0.
Bluetooth 6.0 is the newer standard, but the version number alone does not guarantee longer range, better sound quality, or fewer connection interruptions. The phone or computer, wireless environment, firmware, and selected codec all influence the experience.
The original Air Pro 4 is already unusually well equipped in the audio-codec department. It supports advanced options such as LDAC and Qualcomm’s aptX family, including aptX Lossless, subject to device compatibility. The Plus model retains a similar broad set of audio features.
LDAC can transmit audio at higher bitrates than standard Bluetooth codecs under supported conditions. aptX Lossless aims to deliver lossless CD-quality audio when the compatible devices and connection conditions support that mode. Neither feature guarantees a noticeable improvement with every song or streaming service.
Your phone matters here. iPhones generally use AAC rather than LDAC or aptX Lossless, so iPhone users may not benefit from all the advertised codec options. Compatible Android phones can unlock more choices.
Both models also offer multipoint connectivity, which allows supported connections to two devices simultaneously. You can, for example, connect to a laptop and phone and switch between work audio and calls more conveniently.
Winner: EarFun Air Pro 4+ for Bluetooth version; otherwise, both offer excellent codec support.
5. Battery Life and Charging
Battery life is important if you listen to music for hours, travel frequently, or use your earbuds throughout the working day.
EarFun advertises up to approximately 52 hours of total playback for the Air Pro 4, including its charging case, under specified conditions. The Air Pro 4+ has also been advertised with long total playback figures, reaching up to 54 hours with ANC disabled in some specifications. Actual results vary according to volume, ANC, codec, calls, and other settings.
These maximum figures are not promises of continuous playback under every configuration. Turning on ANC, using high-bitrate codecs, and making frequent calls can reduce operating time.
Both models support USB-C charging and wireless charging, giving users flexible ways to replenish the case. Fast charging can also be useful when you discover that your earbuds are nearly empty before leaving home.
For most listeners, either model offers enough battery capacity for a normal day of commuting, studying, and casual music playback, although heavy users may need to recharge more frequently.
The difference in advertised total battery life is relatively small. It should not be the deciding factor unless independent testing under your preferred settings demonstrates a meaningful advantage.
Winner: Tie for everyday convenience. Compare measured playback time under similar conditions.
6. Microphone and Call Quality
Both models are designed for hands-free calls, voice messages, and online meetings. Their microphone systems use noise-processing technology to help make speech more intelligible in everyday environments.
The Air Pro 4 is a sensible choice for ordinary calls, especially indoors or in quieter surroundings. It can handle conversations without requiring a separate headset, making it practical for students and office workers.
The Air Pro 4+ continues that approach with a feature-rich wireless platform. However, a newer Bluetooth version and a hybrid speaker-driver system do not automatically improve microphone quality.
Background wind, traffic, crowded restaurants, and busy streets can still affect how clearly your voice reaches the other person. Bluetooth earbuds also have limitations compared with dedicated microphones or quality over-ear headsets.
For occasional phone calls and video meetings, both should be considered practical options. If you frequently conduct professional meetings in noisy environments, look for independent microphone samples recorded in realistic conditions before buying.
Winner: No clear winner without a controlled microphone comparison.
7. Comfort, Fit, and Water Resistance
Comfort can determine whether you enjoy using earbuds more than almost any specification on the box.
Both models use silicone ear tips and an in-ear design. A proper seal improves bass response and passive noise isolation, while the right size helps prevent the earbuds from slipping during walks.
The Air Pro 4’s IPX5 rating means it is designed to resist water jets under standardized testing. However, the X indicates that the rating does not specify dust protection.
The Air Pro 4+ is listed with an IP55 rating in some product specifications, which adds a defined level of dust protection alongside water resistance. Check the exact regional listing and documentation before relying on that rating. Neither rating makes the earbuds waterproof or suitable for swimming.
For exercise, both can work for walking, gym sessions, and moderate workouts if they fit securely. Sweat, movement, and personal fit can affect long-term comfort and reliability.
Winner: EarFun Air Pro 4+ if its IP55 rating is confirmed for your version.
8. App Features and Everyday Convenience
The EarFun Audio app is an important part of the experience with both products. It offers access to sound customization and several settings that make the earbuds more useful throughout the day.
Depending on model and firmware, the app can provide:
- Equalizer presets and custom sound profiles.
- ANC, transparency, and other noise-control settings.
- Customizable touch controls.
- Battery information.
- Multipoint connection management.
- Low-latency or gaming mode.
- In-ear detection and automatic playback controls.
The Air Pro 4+ adds advertised AI translation functionality, which may appeal to travelers and people who regularly encounter different languages. Availability and usefulness can depend on the app, supported languages, firmware, and the phone’s capabilities.
However, AI translation should be treated as a convenience feature rather than a replacement for a professional interpreter. Results can be affected by accents, background noise, connectivity, and the complexity of a conversation.
The standard Air Pro 4 already offers extensive customization, so most users will not find the app experience radically different simply because they choose the Plus model.
Winner: EarFun Air Pro 4+ for its additional advertised translation feature; both are strong on customization.
