If you want an open-ear design that keeps you aware of traffic, coworkers and the room around you, choose BUGANI AirCore Open-Ear; if you need active noise cancellation, hi-res LDAC audio and marathon battery life, choose CMF BY NOTHING Headphone Pro Active. These two over-ear headsets solve opposite problems, and that is the whole story here.
• BUGANI AirCore Open-Ear — biggest strength: a hollow-frame open-ear build with snap-on noise-isolating ear caps, so you get awareness when you want it and private listening when you don't.
• BUGANI AirCore Open-Ear — biggest trade-off: noise control is passive only, so it relies on those silicone caps rather than electronics to block sound.
• CMF BY NOTHING Headphone Pro Active — biggest strength: up to 40 dB of adaptive active noise cancellation plus up to 50 hours of ANC-on playback and LDAC hi-res audio.
• CMF BY NOTHING Headphone Pro Active — biggest trade-off: it seals you off from the world, and with a 120 ms latency figure it is the less appealing pick for latency-sensitive gaming.
• Pick BUGANI AirCore Open-Ear if awareness, a lighter open fit and a hybrid open/closed design matter most to you.
• Pick CMF BY NOTHING Headphone Pro Active if you want serious noise cancellation, long battery life and high-resolution streaming.
The AirCore is built around one idea: your ear canal stays open. The hollow-frame design lets air move and keeps you tuned into your surroundings, which is exactly what you want on a bike path, in a shared office or on a walk where you'd rather hear a car before you see it. When you do want to shut the world out, you snap on the removable silicone ear caps and switch into private listening. That flexibility is genuinely rare — most headphones make you choose one mode forever.
Who should buy it: people who want one headset for the commute, the desk and the trail, and who value being able to hear the room. Who should skip it: anyone who flies often or works next to loud machinery, because passive noise cancellation is not going to compete with a real ANC system.
CMF BY NOTHING Headphone Pro Active: Who It's For
The Headphone Pro Active is the opposite philosophy. It is a closed over-ear with adaptive active noise cancellation rated up to 40 dB, and it toggles to Transparency Mode with a button press when you need to hear someone. The 40 mm nickel-plated dynamic drivers are paired with LDAC and dual Hi-Res certification, so if you stream from a service that supports high-bitrate codecs, this headset is designed to take advantage of it.
Battery is the headline: up to 100 hours of playback, or up to 50 hours with ANC on. A five-minute plug-in is quoted at four hours of listening, and it supports on-the-go charging from a phone or laptop. Bluetooth 5.4 adds Google Fast Pair and Microsoft Swift Pair, so setup on Android, Windows and macOS is close to instant. You also get a 3.5 mm jack for wired listening, plus Personal Sound Profile and CMF Spatial Audio with Cinema and Concert modes, all adjusted through the Nothing X app. The earpads are memory foam and the headband is described as cap-friendly.
Who should buy it: commuters, flyers, open-plan-office workers and anyone who wants a big battery and app-level EQ control. Who should skip it: runners and cyclists who need to hear traffic, and competitive gamers — the listed 120 ms latency is far higher than the AirCore's, so audio will trail the picture more noticeably.

If I had to pick one for the way most people actually listen — commuting, working, watching things — I would buy the CMF BY NOTHING Headphone Pro Active. In my opinion, the combination of up to 40 dB of adaptive ANC, up to 50 hours with noise cancellation on, LDAC hi-res audio and a 3.5 mm jack covers more real-world situations than anything else at this level. I would only switch to the BUGANI AirCore Open-Ear if my priority were staying aware of my surroundings or keeping latency as low as possible. Both are solid; they just answer different questions.
Yes, for that use case. The open hollow-frame design leaves your ear canals clear so you can hear traffic and surroundings, and you can add the removable silicone caps later when you want private listening.
The CMF BY NOTHING Headphone Pro Active. It is quoted at up to 100 hours of playback, or up to 50 hours with ANC on, compared with up to 27 hours for the BUGANI AirCore Open-Ear.
Yes. It includes a 3.5 mm jack alongside Bluetooth 5.4 and LDAC, so you can listen wired if the battery runs down or you want a lag-free connection.
Value depends on what you need, not on the number on the page. If you want noise cancellation, long battery life and hi-res codecs, the CMF model is the stronger fit; if you want awareness and a hybrid open/closed design, the BUGANI is. Check the current price on Amazon for each before deciding.
