EarFun Air Pro 4 Plus VS EarFun Clip

The most significant design difference between the EarFun Air Pro 4 Plus and the EarFun Clip is their fit style. The Air Pro 4 Plus uses a traditional in-ear design, where the eartips create a seal inside the ear canal. The Clip, by contrast, adopts an open-ear form factor, which sits on or around the outer ear without occluding the canal. This is a fundamental ergonomic and acoustic trade-off: in-ear designs typically offer better passive noise isolation and a more secure fit during vigorous activity, while open-ear designs prioritize comfort for extended wear and situational awareness, allowing ambient sound to pass through naturally.

Both earbuds share several key design attributes: both are fully wireless (no neckband), both carry an IP55 rating meaning they resist dust ingress and low-pressure water jets from any direction, and neither includes wingtips, RGB lighting, a display, or a UV light. The identical IP55 rating means both are equally suited for workouts and light rain exposure — neither has a protection advantage over the other.

The clear differentiator here is fit style. The choice depends entirely on user preference and use case: the Air Pro 4 Plus's in-ear design suits those prioritizing isolation and audio immersion, while the Clip's open-ear design is the better pick for users who value all-day comfort and awareness of their surroundings. Neither product holds a broader design edge — the decision comes down to which fit philosophy matches the buyer's lifestyle.

The most consequential difference in this group is noise isolation. The EarFun Air Pro 4 Plus offers both Active Noise Cancellation (ANC) and passive noise reduction — a combination that actively suppresses external sound via microphone-driven processing while the in-ear seal physically blocks ambient noise. The EarFun Clip, as an open-ear design, has neither: no ANC and no passive noise reduction. In practical terms, this means the Clip is entirely transparent to surrounding sound, which suits commuters or outdoor users who need situational awareness, but makes it unsuitable for noisy environments where focus or immersion matters.

On raw driver specs, the Clip's 10.8 mm driver is marginally larger than the Air Pro 4 Plus's 10 mm unit. Driver size alone is not a reliable predictor of audio quality — tuning, materials, and enclosure design matter far more — but a slightly larger driver can have more surface area to move air, which may contribute to bass presence. Both products share an identical frequency range of 20 Hz to 20,000 Hz, covering the full extent of human hearing, and neither supports spatial audio, Dolby Atmos, or Dirac Virtuo, so there is no processing-based soundstage advantage on either side.

Overall, the Air Pro 4 Plus holds a clear edge in sound quality versatility for this group. The addition of ANC fundamentally expands the range of environments in which it can deliver a controlled, immersive listening experience — something the Clip simply cannot replicate by design. The Clip's marginally larger driver is a minor footnote against that structural disadvantage.

Battery endurance is where the EarFun Air Pro 4 Plus pulls ahead decisively. Its earbuds last 12 hours on a single charge versus 7.5 hours for the EarFun Clip — a 60% advantage that translates directly into fewer interruptions during long travel days, extended work sessions, or full-day outdoor use. The case gap is equally pronounced: 42 hours of total combined battery for the Air Pro 4 Plus against 22.5 hours for the Clip, meaning users can go nearly two days longer between case recharges.

Both products share an identical 1.5-hour charge time, so the refueling experience is equivalent. Where they diverge again is convenience: the Air Pro 4 Plus supports wireless charging, allowing it to top up on any Qi-compatible pad without hunting for a cable. The Clip lacks this feature entirely, requiring a wired connection every time. For users already invested in a wireless charging ecosystem, this is a meaningful quality-of-life difference.

Across every power metric in this group, the Air Pro 4 Plus holds a clear and consistent advantage — longer earbud runtime, a substantially larger case reserve, and the added flexibility of wireless charging. The Clip's power profile is adequate for moderate daily use, but it cannot match the Air Pro 4 Plus for users who prioritize going longer between charges.

Connectivity is another category where the EarFun Air Pro 4 Plus outpaces the EarFun Clip by a significant margin, starting with the Bluetooth version. The Air Pro 4 Plus runs on Bluetooth 6, while the Clip uses Bluetooth 5.4. Newer Bluetooth generations generally bring improvements in connection stability, power efficiency, and feature support — and in this case, the version gap directly explains several of the codec and protocol differences below.

On audio codec support, the Air Pro 4 Plus is considerably more capable. Both earbuds share LDAC for high-resolution wireless audio, but the Air Pro 4 Plus adds aptX Adaptive, aptX Lossless, and AAC — codecs that collectively offer better compatibility across Android and Apple devices, adaptive bitrate streaming, and in ideal conditions, lossless-quality transmission. The Clip supports only LDAC beyond the baseline, which limits its high-quality audio options to Sony-ecosystem Android devices. Both products deliver identical 50 ms audio latency and the same 10 m maximum Bluetooth range, so day-to-day responsiveness and wireless reach are equivalent.

The Air Pro 4 Plus also supports Bluetooth LE Audio and Auracast — forward-looking standards that enable multi-stream audio sharing and compatibility with next-generation hearing accessibility infrastructure — neither of which the Clip offers. Combined with its newer Bluetooth core and broader codec suite, the Air Pro 4 Plus holds a clear and well-rounded connectivity advantage, making it the stronger choice for users who want future-proof wireless performance and device flexibility.

Functionally, these two earbuds share a solid common baseline: both support fast charging, multipoint connection to two devices simultaneously, on-device controls, a mute function, headset use for calls, voice prompts, and even a included travel bag. For most everyday use cases — switching between a phone and laptop, hopping on a call, or quickly silencing a microphone — either product delivers the same experience.

Where they diverge is in the smarter, more contextual features. The EarFun Air Pro 4 Plus adds ambient sound mode, which electronically pipes in surrounding audio, allowing the user to stay aware of their environment without removing the earbuds. It also includes in/on-ear detection, which automatically pauses playback when an earbud is removed and resumes when reinserted — a small but genuinely useful quality-of-life feature that prevents missed audio and saves battery. The EarFun Clip has neither capability.

Given that the Clip's open-ear design already provides natural ambient awareness, the absence of a dedicated ambient sound mode is less of a practical loss for that product. However, the lack of in-ear detection is a straightforward omission with no design-based justification. Taken together, the Air Pro 4 Plus holds a clear feature advantage in this group, offering a more intelligent and automated user experience on top of an otherwise identical functional foundation.

With only one data point available for this group, the picture is straightforward: both the EarFun Air Pro 4 Plus and the EarFun Clip include a noise-canceling microphone. This means both earbuds are equipped to filter out background noise during calls and voice input, improving speech clarity for the person on the other end in noisy environments such as busy streets or open offices.

Based strictly on the provided specs, this group is a complete tie. Neither product holds any microphone advantage over the other.
