How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want long listening sessions with over-ear comfort and spatial audio, choose GEARit Over-Ear; if you need pocketable earbuds with app-tuned noise control and a proper transparency mode, choose CMF BY NOTHING Buds 2a. That is the short version. The longer version is about how each one handles the world around you — and that is where "transparent mode" becomes the deciding factor for a lot of buyers.
• GEARit Over-Ear — biggest strength: 45 hours of playtime per charge and a full over-ear design with memory foam and fabric cushions, plus 360 spatial audio and multipoint pairing.
• GEARit Over-Ear — biggest trade-off: It is a full-size headphone. It folds, but it still lives in a case, not a pocket, and its noise control is described simply as Active Noise Cancellation without a published transparency figure or app-level tuning.
• CMF BY NOTHING Buds 2a — biggest strength: A 42dB hybrid ANC system with adjustable levels in the Nothing X app — including transparent mode — plus 12.4mm bio-fiber drivers, four mics, and Bluetooth 5.4.
• CMF BY NOTHING Buds 2a — biggest trade-off: Buds playtime is 8 hours on their own (35.5 with the case), the fit depends on ear tips, and the sound leans bass-forward rather than neutral.
• Who GEARit Over-Ear is for: Anyone who wears headphones for hours — desk work, long calls, travel — and wants one charge to cover the whole day.
• Who CMF BY NOTHING Buds 2a is for: Anyone who wants earbuds that let the outside world in on demand, with granular control over how much noise gets blocked.
The GEARit Over-Ear is built around endurance and comfort. The 45-hour average battery life is the headline number here, and the 45-minute charge time means a top-up is a short break, not an overnight event. The earcups are over-ear with memory foam wrapped in fabric, and the whole thing folds down, which matters if you move between a desk, a bag, and a plane seat in the same day.
On features, it covers the modern essentials: Bluetooth 5, multipoint so it can hold two devices at once, touch controls, and 360 spatial audio. The dynamic drivers run the standard 20 Hz to 20,000 Hz range. It ships with a protective case. Noise control is listed as Active Noise Cancellation — no depth figure is published, and there is no mention of an app, so I would treat its noise handling as a fixed, hands-off system rather than something you tune.
That last point is the honest trade-off. If your priority is switching between full isolation and hearing the barista call your name, this headphone does not advertise a transparency mode at all. What it offers instead is stamina — and in my opinion, that is a fair trade for someone who mostly wants to disappear into their own audio for a workday. Skip it if you need something that fits in a jeans pocket, or if you specifically want to control how much outside sound reaches your ears.
The CMF BY NOTHING Buds 2a is the more configurable of the two. The spec sheet lists 42dB hybrid active noise cancellation, and — importantly for this comparison — the Nothing X app lets you adjust ANC levels including transparent mode. So the answer to "how do I let sound in?" is not a physical button dance; it is a setting you can tune. That is the single biggest functional difference between these two products.
The audio side is deliberately flavored. A 12.4mm bio-fiber dynamic driver, co-tuned with DIRAC, aiming at a warm soundstage, rich mids, and what the spec sheet calls crisp and thundering bass, with an option to turn that bass off or customize it. Four HD ENC mics with clear voice tech and wind noise reduction 2.0 handle calls, and Bluetooth 5.4 adds Google Fast Pair and Microsoft Quick Switch. Connectivity range is listed at 10 meters.
The practical numbers: 8 hours of bud playtime, 35.5 hours with the case, a 460 mAh case battery, and an 89-minute charge time — with a quick-charge claim of up to 2 hours of playback from 5 minutes of charging. The case itself is small (5.5 cm square, 23 mm tall) and the whole set weighs 42.75 grams. You also get ear tips in S, M, and L, an IP54 rating, lanyard readiness, and a gaming low-lag mode.
Who should skip it? If you hate things in your ear canal, or you want a sound signature that stays flat and neutral, or you want a headphone rather than earbuds, this is not your pick. The bass-forward tuning and in-ear fit are both deliberate choices, not flaws — but they are choices you have to want.

I would buy the CMF BY NOTHING Buds 2a — because the question that started this comparison was transparency mode, and that is exactly where the Buds 2a is built to win. Adjustable ANC levels with a transparent setting, four mics, app-based EQ, and Bluetooth 5.4 add up to more control over how I hear the world. That said, if my day were eight hours of desk work and long calls rather than commuting and movement, I would take the GEARit Over-Ear without hesitation: 45 hours of playtime and memory foam over-ear cushions are hard to argue with. Match the product to how you actually listen, and check the current price on Amazon before you commit.
Transparency mode uses the microphones to pipe outside sound into your ears instead of blocking it, so you can hear conversations, announcements, or traffic without removing your headphones. On the CMF BY NOTHING Buds 2a it is one of the adjustable ANC levels in the Nothing X app. The GEARit Over-Ear lists Active Noise Cancellation but does not advertise a transparency mode in its specifications.
It is for situations where full isolation is unsafe or rude — crossing a street, ordering coffee, hearing a gate announcement, or keeping an ear on a coworker. Earbuds like the Buds 2a make it easy because you can switch levels from your phone. Over-ear designs without a transparency setting tend to force you to slide a cup off one ear instead.
On the Buds 2a, you change the ANC level in the Nothing X app — moving from transparent back to ANC or off. There is no universal hardware shortcut, so the app or the touch controls are your route. If your headphones do not list transparency mode as a feature, there is nothing to switch off; noise control simply stays in ANC.
The CMF BY NOTHING Buds 2a lists app-based control alongside touch control, so the app is where the ANC levels including transparent mode are adjusted. Without a companion app, a headphone with fixed ANC — like the GEARit Over-Ear — has no transparency setting to access at all. Plan for the app if that feature matters to you.
