EarFun Air Pro 4 Plus VS LG XBoom Buds

Both the EarFun Air Pro 4 Plus and the LG XBoom Buds share the same fundamental design DNA: fully wireless, in-ear fit with no neckband, stereo playback, and no gimmicks like RGB lighting or a display. For most users, this means a clean, familiar true wireless experience from both sides.

The most meaningful differentiator in this group is protection. The EarFun Air Pro 4 Plus carries an IP55 rating, meaning it is tested against both dust ingress and water jets from any direction — making it a solid companion for outdoor workouts or light rain. The LG XBoom Buds, by contrast, holds only an IPX4 rating, which covers sweat and light splashes but offers no dust protection and less water resistance overall. For gym-only use this gap is negligible, but for outdoor or commuting scenarios the EarFun's higher rating provides meaningfully broader coverage.

One area where the LG XBoom Buds push back is the inclusion of wingtips, which can improve ear stability during high-movement activities — something the EarFun omits. Still, on balance, the EarFun Air Pro 4 Plus holds a clear design edge in this group thanks to its superior IP55 protection, while the XBoom Buds' wingtips offer a minor fit advantage for active users who prioritize secure wear over environmental resistance.

On paper, the sound quality specs for these two earbuds are a perfect mirror image. Both feature a 10 mm dynamic driver, an identical frequency range of 20 Hz – 20,000 Hz, and both include active noise cancellation layered on top of passive noise reduction — a combination that addresses both low-frequency rumble (through ANC) and higher-frequency ambient noise (through physical ear seal).

Neither earbuds support spatial audio, Dolby Atmos, or Dirac Virtuo, so users seeking an immersive, cinema-like soundstage should temper expectations on both sides. The standard 20 Hz–20 kHz range covers the full extent of human hearing, meaning neither product is spec-limited for typical listening; real-world tuning and DSP choices, which are not captured in these specs, would be the actual differentiators in practice.

Based strictly on the provided data, this group is a complete tie. Every measurable sound quality spec is identical across both products, so the comparison here cannot favor either side. A buyer's decision in this category would need to rest on hands-on listening rather than on spec-sheet differences.

Battery endurance is where the EarFun Air Pro 4 Plus pulls ahead decisively. Its earbuds last 12 hours per charge versus 10 hours for the LG XBoom Buds — a modest but real gap for long travel days or extended listening sessions. The bigger story, however, is the charging case: the EarFun's case delivers 42 hours of total combined playback, more than double the XBoom Buds' 20 hours. In practice, this means EarFun users can go several days without hunting for a power outlet, while LG users will need to recharge the case roughly twice as often under similar usage patterns.

The LG XBoom Buds do recover some ground with a faster charge time of 1 hour compared to the EarFun's 1.5 hours — useful when you need a quick top-up before heading out. But the EarFun counters with wireless charging support, a convenience the XBoom Buds lack entirely. For users who already have a Qi pad on their desk or nightstand, this removes the need to fish out a cable altogether.

Taken as a whole, the EarFun Air Pro 4 Plus holds a clear power advantage in this group. Its combination of longer earbud runtime, significantly larger case reserve, and wireless charging capability outweighs the LG's faster wired charge time for most real-world use cases.

The connectivity gap between these two earbuds is substantial, and it starts at the foundation. The EarFun Air Pro 4 Plus runs on Bluetooth 6, the latest generation, while the LG XBoom Buds use Bluetooth 5.4. In practical terms, Bluetooth 6 brings improvements in connection reliability and efficiency, though both share the same stated 10 m maximum range. The more impactful difference lies in codec support: the EarFun offers LDAC, aptX Adaptive, and aptX Lossless — a trio that enables high-resolution and near-lossless wireless audio transmission when paired with a compatible source device. The LG XBoom Buds support only AAC beyond the standard SBC baseline, which is a meaningfully thinner codec roster.

For audiophiles or users with hi-res music libraries, this distinction matters considerably. LDAC can transmit up to three times more data than AAC, and aptX Lossless is capable of bit-perfect CD-quality streaming over Bluetooth — neither of which is available on the XBoom Buds. Casual listeners streaming compressed audio may not notice a difference day-to-day, but the EarFun's codec flexibility future-proofs the experience and unlocks higher quality ceilings on compatible Android and hi-res devices.

Where both products stand equal: fast pairing, USB Type-C, Bluetooth LE Audio, Auracast broadcast support, and AAC compatibility. These shared features ensure solid baseline connectivity for both. Still, the EarFun Air Pro 4 Plus holds a clear and meaningful edge in this group, driven by its newer Bluetooth version and far richer high-quality codec support.

Across most of the features in this group, the two earbuds are evenly matched. Ambient sound mode, fast charging, mute, headset capability, on-device controls, voice prompts, and an included travel bag are all present on both — a strong shared baseline that covers the practical needs of most daily users.

The single differentiator here is in/on-ear detection, which the EarFun Air Pro 4 Plus supports and the LG XBoom Buds do not. This feature automatically pauses playback when an earbud is removed and resumes when it is reinserted — a small but genuinely useful quality-of-life convenience that reduces the need to manually pause audio during brief interruptions like conversations or announcements.

It is a narrow gap, but the EarFun Air Pro 4 Plus takes a slight edge in this group solely on the strength of its in/on-ear detection. For users who frequently take one earbud out throughout the day, this translates into a noticeably smoother and more intuitive experience. Those who rarely remove their earbuds mid-session will find both products essentially equivalent here.

Microphone hardware is identical across both earbuds. Each carries 6 microphones total alongside noise-canceling microphone technology — a configuration typically used to support beamforming and multi-mic array processing, which helps isolate the speaker's voice while suppressing wind, crowd, and ambient background noise during calls.

A 6-mic setup is a generous count for consumer true wireless earbuds, generally associated with above-average call quality and more effective ANC mic arrays. The fact that both products match on this count means neither holds a spec-level advantage for voice calls, virtual meetings, or voice assistant interactions.

This group is a complete tie. With every provided data point identical, there is no basis to favor either the EarFun Air Pro 4 Plus or the LG XBoom Buds here. Real-world call quality differences, if any, would come down to software processing and tuning rather than anything reflected in these specs.
