EarFun Air Pro 4 Plus VS QCY MeloBuds N70

In terms of overall design, the EarFun Air Pro 4 Plus and the QCY MeloBuds N70 share a nearly identical profile: both are true wireless, in-ear earbuds with no neckband, no wingtips, no RGB lighting, no display, and stereo speaker configurations. For users scanning for a design differentiator in form factor or aesthetic features, these two are effectively matched.

The one meaningful distinction lies in their IP ratings. The EarFun Air Pro 4 Plus carries an IP55 rating, while the QCY MeloBuds N70 is rated IPX5. Both protect against water jets from any direction, so rain and sweat resistance are equally handled. However, the additional ″5″ dust rating on the EarFun means it also offers certified protection against dust ingress — something the QCY's ″X″ dust designation leaves untested and unverified. In real-world use, this matters most in dry, dusty environments like construction sites, gyms with chalk, or sandy outdoor settings.

Overall, the EarFun Air Pro 4 Plus holds a narrow but genuine edge in this category purely due to its dual-certified IP55 rating versus the QCY's water-only IPX5. For most everyday users, this difference is minor, but for anyone who frequently operates in dusty conditions, the EarFun offers a more complete layer of environmental protection.

Across every sound quality specification provided, the EarFun Air Pro 4 Plus and the QCY MeloBuds N70 are a perfect mirror of each other. Both deliver a standard 20 Hz – 20,000 Hz frequency range — the full span of human hearing — and both combine active noise cancellation with passive noise reduction for a layered approach to blocking ambient sound.

Neither earbud supports spatial audio, Dolby Atmos, or Dirac Virtuo, and neither lists a neodymium magnet driver. This means users looking for an immersive, cinema-style soundstage or audiophile-grade driver hardware won't find a differentiator here between the two. The ANC on both is a meaningful feature for commuters or open-plan office workers, but the specs alone don't reveal implementation quality — depth of cancellation, transparency mode behavior, or tuning — so real-world ANC performance cannot be ranked from this data.

This group is a complete tie. Every measurable sound quality attribute provided is identical across both products, giving neither a spec-based advantage. Buyers will need to rely on hands-on listening tests or independent reviews to distinguish between them in actual audio performance.

Battery endurance slightly favors the EarFun Air Pro 4 Plus across the board. Its earbuds last 12 hours per charge versus 10 hours for the QCY MeloBuds N70, and with ANC enabled that gap holds — 8 hours compared to 7 hours. The total system stamina (earbuds plus case) follows the same pattern at 42 hours versus 40 hours. None of these differences are dramatic, but the EarFun consistently pulls ahead, and for heavy daily users the extra two hours of earbud runtime can meaningfully reduce how often you reach for the case mid-day.

Where the gap becomes more significant is charging convenience. The EarFun supports wireless charging, while the QCY requires a wired connection every time. For users already living in a Qi ecosystem — a wireless pad on the desk or nightstand — this is a genuine quality-of-life advantage that reduces cable dependency. Both share an identical 1.5-hour wired charge time, so the parity ends there.

The EarFun Air Pro 4 Plus holds a clear edge in this category. It outlasts the QCY MeloBuds N70 on every battery metric and adds wireless charging on top — making it the stronger choice for users who prioritize power flexibility and fewer interruptions throughout the day.

Both earbuds share the same Bluetooth 6 foundation, identical 10 m range, USB-C charging, and support for LDAC and AAC — so the baseline wireless experience is competitive. But the codec story diverges sharply from there. The EarFun Air Pro 4 Plus adds aptX Adaptive and aptX Lossless to its arsenal, enabling dynamically optimized, high-resolution audio transmission that the QCY MeloBuds N70 simply cannot match. For listeners pairing with compatible Android devices and prioritizing audio fidelity over a wired connection, this is a tangible, audible difference.

The EarFun's connectivity advantages extend beyond codecs. It supports Bluetooth LE Audio and Auracast — two forward-looking standards that enable features like multi-stream audio sharing and public broadcast compatibility — neither of which the QCY offers. Add in fast pairing for quicker device handshakes, and the EarFun is clearly built for a more feature-rich and future-ready wireless ecosystem. The QCY, by contrast, sticks to a leaner, more conventional connectivity profile.

The EarFun Air Pro 4 Plus wins this category decisively. Its combination of next-generation codecs, LE Audio, Auracast, and fast pairing gives it a substantially broader and more capable connectivity stack than the QCY MeloBuds N70, which offers little beyond the shared basics.

The functional foundations are shared: both the EarFun Air Pro 4 Plus and the QCY MeloBuds N70 offer ambient sound mode, fast charging, mute, headset use, on-device controls, voice prompts, and a travel bag. For everyday usability, these are the features most users interact with daily, and neither product is lacking in that core set.

Two exclusive features tip the balance toward the EarFun. First, in-ear detection — the ability to auto-pause playback when an earbud is removed — is a small but frequently appreciated convenience that the QCY omits. Second, and more distinctively, the EarFun includes a built-in translator, a real-time language translation feature that positions it as a practical travel and communication tool beyond standard listening use. The QCY offers no equivalent.

The EarFun Air Pro 4 Plus takes this category. While the QCY MeloBuds N70 covers the essentials competently, the EarFun's addition of in-ear detection and a built-in translator represents a meaningfully richer feature set — particularly for users who travel frequently or value smarter playback automation.

On paper, the microphone setups of the EarFun Air Pro 4 Plus and the QCY MeloBuds N70 are identical: both deploy 6 microphones with noise-canceling capability. A six-mic array is a generous configuration at this tier, typically enabling beamforming and multi-point voice pickup that helps isolate the caller's voice from surrounding noise — useful in busy streets, offices, or public transport.

This is a complete tie based on the available data. With no differentiating specs between them — same mic count, same noise-canceling feature — neither product holds a measurable advantage here. As with ANC performance, actual call quality and voice clarity will depend on the implementation, tuning, and processing algorithms behind that hardware, none of which can be assessed from these specs alone.
