If you want long battery life, IP55 water and dust resistance, and a jogging-friendly pick, choose CMF BY NOTHING Buds 2; if you need dual-device connectivity and smarter noise adjustment, choose Nothing Ear. For jogging, I’d lean toward CMF because its stated resistance and longer total listening time suit an active routine.
In this CMF by Nothing vs Nothing earbuds comparison, the deciding factors are practical: workout protection and endurance on one side, device switching and adaptive noise control on the other.
• CMF BY NOTHING Buds 2: Its biggest strengths are up to 55 hours of total listening with the case and IP55 water and dust resistance. The trade-off: it does not list dual-device connectivity.
• Nothing Ear: Its standout features are dual-device connectivity and adaptive ANC that can adjust to noise leakage. The trade-off: its stated total listening time is over 42.5 hours with ANC off, and no IP resistance rating is provided.
• Choose CMF BY NOTHING Buds 2 if your priority is a jogging-friendly design, extended listening time, and a quick top-up that provides up to 7.5 hours of playback.
• Choose Nothing Ear if you regularly switch between a laptop and phone, or want ANC that can adapt to your surroundings and earbud seal.
• Both use 11 mm drivers, offer hybrid noise cancellation, include six microphones, and work with the Nothing X app.
CMF BY NOTHING Buds 2 makes a strong case for an active routine. Its IP55 water and dust resistance is a concrete advantage for jogging, workouts, and days when you might encounter rain. The product information also lists rounded in-ear tips, while the feature description includes environmental adaptive ANC that changes noise reduction to suit your surroundings. Together, those details point to earbuds designed for everyday movement as well as listening at home.

I’d choose CMF for jogging or for anyone who values resistance and long intervals between charges more than switching between two devices. I’d skip it if dual-device connectivity is essential: that feature is listed for Nothing Ear, not Buds 2. CMF offers noise cancellation up to 48 dB, but that number alone doesn’t tell you how well ANC will work with your personal fit or which sounds you’ll notice during a run.
Nothing Ear suits someone whose earbuds move between work and personal devices. Its dual-device connectivity is intended to let you switch between a laptop and phone, a useful feature if you often take a call on one device and return to audio on another. Adaptive ANC responds to the surroundings, while the product also describes monitoring the earbud seal and adjusting cancellation when it detects leakage. That gives Nothing Ear a more specific noise-control story than a simple fixed setting.
The listed ANC figure is up to 45 dB, and the app offers three cancellation levels as well as adaptive control. The earbuds use 11 mm drivers, and the product information gives a frequency range of 20 Hz to 20 kHz. For calls, Nothing lists six microphones and Clear Voice Technology. Battery life is stated as over 42.5 hours total with the case when ANC is off; a 10-minute charge is specified to provide up to 10 hours of playback with ANC off.
I’d choose Nothing Ear if your routine involves several devices and you want more control over how noise cancellation responds. It may also suit someone who values fast charging: the stated playback from a 10-minute charge is longer than CMF’s claim, though the conditions provided for Nothing Ear specify ANC off. I’d think carefully before choosing it as a jogging-first option: the available product details don’t provide an IP water or dust resistance rating, so I can’t compare workout protection directly.
Side-by-Side: Which Should You Choose?
• Best fit for jogging → CMF BY NOTHING Buds 2. Its stated IP55 water and dust resistance makes it the clearer choice for exercise and exposure to rain.
• Best for switching between laptop and phone → Nothing Ear. Dual-device connectivity is an explicitly listed feature.
• Best for adaptive ANC details → Nothing Ear. It can respond to surroundings and adjust cancellation when it detects noise leakage around the earbud seal.
• Best stated ANC figure → CMF BY NOTHING Buds 2. Its listed maximum is 48 dB, while Nothing Ear lists up to 45 dB. Those figures aren’t a guarantee of a better experience for every listener.
• Best quick charge for a short break → Nothing Ear, with a caveat. Its 10-minute charge is stated to provide up to 10 hours of playback with ANC off; CMF lists up to 7.5 hours from the same charging interval.
• Best for sound customization and spatial effects → CMF BY NOTHING Buds 2. Its features include EQ and Ultra Bass adjustments in the Nothing X app, plus an HRTF-based spatial audio effect.
• Best multipoint Bluetooth headset for jogging? → Neither is a perfect match based on these details. Nothing Ear lists dual-device connectivity, while CMF is the more clearly documented workout pick because it lists IP55 protection. For jogging, I’d put that distinction ahead of multipoint if device switching isn’t essential.
I’d buy CMF BY NOTHING Buds 2 for my everyday routine, especially if jogging is part of it. IP55 resistance and up to 55 hours with the case give it the more reassuring exercise-and-endurance profile.
Nothing Ear is the better fit if I needed dual-device connectivity and more adaptive ANC behavior. But for jogging, I’d rather prioritize the product with a stated water and dust resistance rating. That’s why CMF is my pick here, even though Nothing Ear has the more useful device-switching feature.
