CMF BY NOTHING Buds Pro 2 vs Nothing Ear Noise Cancelling at a Glance
• CMF BY NOTHING Buds Pro 2: 50dB adaptive hybrid ANC, a smart case dial, and up to 43 hours of total playback. Trade-off: Bluetooth 5.3 is older than Nothing’s Bluetooth 6.0.
• Nothing Ear Noise Cancelling: Bluetooth 6.0, four ear-tip sizes including XS, and audio snapshot and call-recording features. Trade-off: stated total playback is up to 42 hours, and the available ANC figure is lower at up to 45dB.
• CMF is for: joggers and everyday listeners who value battery life, straightforward case controls, and ANC with an ambient mode.
• Nothing is for: people who want more fit-size options, adjustable sound, dual-device connections, and recording or AI tools.
The CMF Buds Pro 2 make a strong case for a buyer who wants a practical pair of earbuds for daily listening, commuting, and jogging. Their listed adaptive hybrid ANC reaches up to 50dB, and the product description says the earbuds can detect noise leakage and adjust cancellation. Transparency mode is also available, which matters when you want some awareness of what is happening around you rather than shutting the world out.
The case’s smart dial is a distinctive convenience: it can be used to adjust volume, tracks, and noise modes without relying only on the earbuds’ touch controls. Bluetooth 5.3 supports multipoint connectivity, so the buds can connect to two devices. For calls, CMF lists six HD microphones and Clear Voice Technology 3.0. The dual-driver setup pairs an 11mm bass driver with a 6mm tweeter, and LDAC support is included for compatible listening setups.

Battery life is a particular strength on paper. CMF states up to 10 hours from a single charge and up to 43 hours with the case, plus three hours of playback from a 10-minute charge. The IP55 design is another practical point for active use. I’d shortlist these if you want a jog-friendly set with useful controls, robust stated battery figures, and an ambient mode. Skip them if Bluetooth 6.0 or Nothing’s recording and AI features matter more to you.
Nothing Ear (3a), the model identified here as Nothing Ear Noise Cancelling, suits someone who wants more than basic playback and noise control. Its 12mm driver supports Hi-Res Audio, and the Nothing X app offers sound adjustment through bass, treble, vocals, and an eight-band EQ. There are also three ANC strength modes and Transparency Mode, giving you choices for different surroundings rather than a single noise-control setting.
The fit details may be useful if standard ear tips tend not to work for you: Nothing lists four sizes, from XS through L. Bluetooth 6.0 and dual-device connections are aimed at people moving between a phone and computer or another compatible device. Nothing also describes one-touch AI features and audio snapshot and call recording. Those recording tools have limits: audio snapshot is listed for up to a minute, while calls and meetings can be recorded for up to two hours; call recording is available only in supported regions.
The trade-offs are straightforward in the supplied figures. The case provides up to 42 hours of listening, and each bud is listed for up to 10 hours with ANC off or six hours with ANC on. A five-minute charge is stated to provide up to an hour of playback. I’d consider Nothing if fit choices, app-based sound shaping, and its newer connection and recording tools appeal to you. If your priority is the higher stated ANC figure or the slightly longer total-playback claim, CMF has the clearer specification advantage.
Side-by-Side: Which Should You Choose?
• Best stated total battery life → CMF BY NOTHING Buds Pro 2. CMF lists up to 43 hours with the case; Nothing lists up to 42 hours.
• Best for jogging with an ambient mode → CMF BY NOTHING Buds Pro 2. Its product information specifically describes keeping you alert during runs, alongside transparency mode and an IP55 design.
• More ear-tip size choices → Nothing Ear Noise Cancelling. It includes XS, S, M, and L, which gives you an extra listed option for finding a comfortable seal.
• Newer Bluetooth version → Nothing Ear Noise Cancelling. It specifies Bluetooth 6.0; CMF specifies Bluetooth 5.3.
• Case-based listening controls → CMF BY NOTHING Buds Pro 2. The smart dial is designed to adjust volume, tracks, and noise modes from the case.
• Sound personalization and recording tools → Nothing Ear Noise Cancelling. Its app includes an eight-band EQ, while its feature set also includes audio snapshot and call recording, subject to regional availability.
• Calls and meetings across devices → Consider Nothing Ear Noise Cancelling if recording matters; consider CMF if you mainly want mic-focused calls. Nothing lists recording features and dual-device connections. CMF lists six microphones and Clear Voice Technology 3.0.
I’d choose CMF BY NOTHING Buds Pro 2 for jogging and everyday use because its stated 43-hour total battery life, smart case dial, and run-aware transparency features make a focused, practical combination. Its higher listed ANC figure is another point in its favor, though that number shouldn’t be treated as a guarantee of a better fit or result for every listener.
Nothing Ear Noise Cancelling makes more sense if its extra ear-tip size, Bluetooth 6.0, EQ, or recording tools solve a need you already have. But if I were choosing one pair for jogging, I’d pick CMF.
