1More Q21 VS QCY MeloBuds N70

In terms of design, the 1More Q21 and the QCY MeloBuds N70 are virtually identical across every measured dimension. Both are in-ear, fully wireless earbuds with no neckband, no wingtips, no RGB lighting, no display, and an identical IPX5 water resistance rating — meaning both can handle sweat and rain splashes but should not be submerged.

The IPX5 rating is a solid, practical standard for workout and commute use, offering reliable protection against low-pressure water jets from any direction. Neither product offers a more robust rating like IPX7 or IP57, so neither has an edge for heavy water exposure scenarios.

With no differentiating design features between them in this spec group, the two products are in a complete tie on design. A buyer choosing between them on design alone will find no meaningful distinction — the decision will need to come down to other spec groups such as audio performance, battery life, or connectivity.

Both the 1More Q21 and the QCY MeloBuds N70 share an identical sound quality profile on paper. Each offers active noise cancellation (ANC) alongside passive noise reduction — a combination that addresses both the electronic and physical sides of isolation. ANC is a meaningful differentiator at this price tier, actively countering low-frequency ambient noise like commuter rumble or office hum in real time.

The frequency response of 20 Hz – 20,000 Hz on both units covers the full range of human hearing, which is standard for consumer earbuds. Neither product extends into high-resolution territory (such as 40 kHz), so neither claims a technical edge for hi-res audio formats. Spatial audio, Dolby Atmos, and Dirac Virtuo are all absent on both, meaning users seeking immersive or cinema-grade processing will not find it here.

With every measurable sound quality spec matching exactly, this category is a dead tie. Neither the Q21 nor the MeloBuds N70 holds an advantage — audio performance distinctions between them, if any exist, would come down to tuning and driver implementation rather than anything reflected in the provided specifications.

Battery life is where these two products diverge sharply. The QCY MeloBuds N70 delivers 10 hours of playback per charge versus 5.5 hours for the 1More Q21 — nearly double the endurance. That gap is even more pronounced with ANC enabled: the N70 sustains 7 hours while the Q21 drops to 4 hours, a difference that becomes very noticeable during long flights or full workdays.

The total system battery tells a similar story. The Q21's case holds 600 mAh and extends overall listening to 24.4 hours, while the N70's smaller 480 mAh case manages a remarkable 40 hours total — indicating the N70's earbuds themselves are considerably more power-efficient. Charge time is identical at 1.5 hours for both, so the N70 simply offers far more output per cycle without any trade-off in refueling speed. Neither model supports wireless charging.

The QCY MeloBuds N70 holds a decisive edge in this category. For users who prioritize going longer between charges — whether for travel, long commutes, or all-day use — the N70's superior endurance is a meaningful, practical advantage that the Q21 cannot match on these specs alone.

The most meaningful distinction in this category is the Bluetooth version. The QCY MeloBuds N70 ships with Bluetooth 6.0, while the 1More Q21 uses Bluetooth 5.4. Bluetooth 6.0 introduces improved connection precision and more efficient channel management, which translates to more stable pairing in congested wireless environments and potential efficiency gains that can contribute to battery savings over time.

On codec support, both earbuds are evenly matched — each carries LDAC and AAC, covering high-quality wireless audio for Android and Apple ecosystems respectively. LDAC in particular is notable, supporting bitrates up to 990 kbps for near-lossless streaming when the source device supports it. Neither product includes aptX variants or Bluetooth LE Audio, so users in the Qualcomm ecosystem or those seeking Auracast broadcast audio will find no support on either side.

The QCY MeloBuds N70 earns a narrow edge here solely on the strength of its newer Bluetooth 6.0 standard. The codec lineup and maximum range of 10 m are identical, so the practical day-to-day gap may be modest — but the N70 is the more future-facing option from a connectivity standpoint.

Across the features category, the 1More Q21 and the QCY MeloBuds N70 are perfectly matched. Both support ambient sound mode — a practical necessity for staying aware of surroundings during commutes or outdoor use — alongside fast charging, a mute function, on-device touch controls, and voice prompts. The inclusion of a travel bag on both models is a small but welcome addition for users who carry their earbuds frequently.

Worth noting is what neither product offers: there is no in-ear detection, no find-device feature, and no notification readout on either side. The absence of in-ear detection in particular means playback will not automatically pause when an earbud is removed — a convenience gap that some users coming from premium-tier earbuds may notice. Both products are also confirmed capable of functioning as a headset, supporting microphone use for calls, which broadens their utility beyond passive listening.

With every feature spec aligning identically, this category is a complete tie. Neither the Q21 nor the MeloBuds N70 offers a functional advantage here, and the decision between them continues to rest on the differentiators found in other categories such as battery life and connectivity.

Microphone hardware is where another gap opens between these two. The QCY MeloBuds N70 packs 6 microphones compared to 4 on the 1More Q21. Both employ noise-canceling microphone arrays, but the higher mic count on the N70 allows for more sophisticated beamforming and wind/ambient noise rejection — practically meaning cleaner voice pickup during calls in noisy environments like busy streets or open offices.

A 4-mic setup is already a reasonable standard for call quality at this tier, capable of decent noise isolation when the signal processing is well-tuned. The step up to 6 mics, however, provides additional spatial data points for the firmware to work with, which generally improves the system's ability to distinguish the user's voice from surrounding noise — a tangible benefit for anyone who takes frequent calls on the go.

The QCY MeloBuds N70 holds a clear advantage here. While real-world call quality depends on software implementation as well, the N70's 6-microphone array gives it a structural hardware edge over the Q21's 4-mic configuration that is difficult to overcome through processing alone.
