Huawei FreeArc VS Xiaomi Open Earphones Pro

Both the Huawei FreeArc and the Xiaomi Open Earphones Pro share the same fundamental design philosophy: open-ear, fully wireless form factors with stereo speakers and no RGB or display gimmicks. This keeps both focused on audio utility rather than aesthetics. However, the differences in protection and fit security reveal meaningfully different target use cases.

The most significant differentiator here is water resistance. The FreeArc carries an IP57 rating, meaning it is fully waterproof and can withstand submersion in up to 1 meter of water — a genuine safeguard for outdoor or rain-exposed use. The Xiaomi Open Earphones Pro, rated at IP54, is only sweat resistant, offering protection against splashes and perspiration but nothing beyond that. For gym-goers or light commuters this may suffice, but for runners or outdoor athletes who train in variable weather, the FreeArc's rating provides real peace of mind that the Xiaomi simply cannot match.

The FreeArc also includes wingtips for a more secure physical fit — a meaningful addition for open-ear designs, which by nature lack the in-canal grip of traditional earbuds. The Xiaomi omits these, relying solely on its ear-hook geometry to stay in place during movement. On balance, the Huawei FreeArc holds a clear advantage in this group, offering superior weather protection and a more secure fit system — both of which matter most to active users.

At the foundational level, both earphones cover the full standard audible range of 20 Hz to 20000 Hz, meaning neither is handicapped in terms of frequency response on paper. Neither offers ANC, which is expected given their open-ear designs — isolating external sound is structurally at odds with the open-ear concept. What separates them, however, are the additional sound features layered on top of this shared baseline.

The Xiaomi Open Earphones Pro includes passive noise reduction and, more notably, spatial audio support. Passive noise reduction in an open-ear form factor is a modest but real benefit — it indicates some physical shaping or material choice aimed at softening ambient intrusion without sealing the ear. Spatial audio is the more impactful differentiator: it enables a three-dimensional soundstage, making content like movies, games, and certain music feel more immersive and directionally aware. The Huawei FreeArc offers neither of these, presenting a comparatively flat sound feature set.

For users who primarily want open-ear awareness with basic stereo playback, both are functionally similar. But for anyone who values an enhanced listening experience — particularly with multimedia content — the Xiaomi Open Earphones Pro holds a clear advantage in this category, driven entirely by its spatial audio capability.

Battery endurance is where the Xiaomi Open Earphones Pro pulls ahead decisively. Its 8.5-hour earbud runtime outpaces the FreeArc's 7 hours by a meaningful margin — that extra 1.5 hours can be the difference between making it through a full workday or a long-haul flight without reaching for the case. More striking is the combined total: the Xiaomi delivers 36.5 hours of case-backed battery life versus the FreeArc's 21 hours, a gap of over 15 hours that speaks to a significantly larger charging case capacity.

The FreeArc does reclaim some ground on charging speed, refilling in 1 hour compared to the Xiaomi's 1.5 hours. For users who regularly top up between sessions, this half-hour advantage is a practical convenience. Neither model supports wireless charging, so both require a cable regardless.

On balance, the Xiaomi Open Earphones Pro holds a clear advantage in this category. Unless rapid wired charging is a top priority, the Xiaomi's substantially longer total runtime makes it the stronger choice for users who travel frequently or dislike managing daily charging routines.

Shared ground between these two is substantial: identical 10-meter Bluetooth range, USB-C charging, AAC codec support, and wireless-only operation. Neither offers NFC pairing or fast pairing, so the out-of-box connection experience is broadly equivalent. The differences, while fewer, carry real weight for discerning listeners.

The Xiaomi Open Earphones Pro runs on Bluetooth 5.4, a step ahead of the FreeArc's 5.2. In practice, 5.4 brings improvements in connection reliability and power efficiency, though the real-world gap at this range tier is subtle. More consequential is the Xiaomi's support for LDHC — a high-resolution audio codec capable of transmitting at significantly higher bitrates than AAC. For users with hi-res audio libraries or compatible source devices, LDHC can deliver noticeably richer audio fidelity over Bluetooth. The Huawei FreeArc, limited to AAC, cannot match this ceiling.

The Xiaomi Open Earphones Pro takes a clear edge here. Its newer Bluetooth version and exclusive LDHC support make it the stronger option for users who prioritize wireless audio quality, while the FreeArc offers a competent but more basic connectivity package.

Across this feature set, the two earphones are remarkably aligned. Fast charging, on-device controls, a mute function, headset capability, voice prompts, and an included travel bag are all present on both — painting a picture of two products aimed at a similar practical use case with comparable quality-of-life provisions.

The sole differentiator is in/on-ear detection, which the Huawei FreeArc supports and the Xiaomi does not. This feature automatically pauses playback when an earbud is removed and resumes when it is put back in — a small but genuinely useful convenience that reduces manual interaction and prevents missed audio during brief interruptions. Its absence on the Xiaomi Open Earphones Pro is a minor but real omission for users who frequently take earphones on and off throughout the day.

This is a close category overall, but the Huawei FreeArc takes a narrow edge purely on the strength of its ear-detection functionality. For users who value seamless, hands-free playback management, it is the more polished option here; those who rarely remove their earphones mid-session will find the practical gap negligible.

Both the Huawei FreeArc and the Xiaomi Open Earphones Pro include a noise-canceling microphone, which is a meaningful baseline to share. For open-ear designs — which by nature sit in acoustically exposed environments — microphone noise cancellation is particularly valuable, helping to filter out ambient sound during calls so that the speaker's voice comes through more clearly to the other party.

With only a single shared data point in this category, there is no basis to distinguish between the two products here. This is a straight tie: both earphones are equally specified on microphone capability as far as the available data indicates.
