DISCLAIMER
1. The noise cancellation limit of up to 42 dB is the theoretical maximum limit. This data comes from the Nothing laboratory. Since the actual noise cancellation achieved may vary depending on the specific environment, please refer to the performance of the actual product.
2. Place the earbuds into the charging case and close the case lid for charging. 35.5 hours of audio playback, with the earbuds and charging case fully charged, Active Noise Cancellation turned off, 50% volume, and with AAC format and the rest of the features at default settings. Test results are based on the Nothing laboratory results (25° C or 77° F). Fast Charge your CMF Buds 2a using a standard adapter or Type-C USB charging cable. Requires 5V⎓1A adapter or higher. Actual battery life is affected by volume, frequency and duration of incoming calls, output source, environmental interference, product features used, usage habits and other factors. Actual experience will depend on individual use.
Fast Charge: Once the earbuds and charging case are out of power, fast-charge for 10 minutes, with Active Noise Cancellation turned off, 50% volume and AAC format and the rest of the features at default settings. After a 10-minute charge with the case, the earbuds plus deliver up to 5.5 hours of music playback; without the case, it’s up to 2 hours. Charging and battery test results are based on the Nothing laboratory results (25° C or 77° F). Charging and battery life test data was measured using Nothing Power (45W) at an ambient temperature (25° C or 77° F) in the Nothing laboratory. When the charging case is connected to a type-C cable, CMF Buds 2a will fully charge from 0-100% in 89 minutes. With the case unplugged, the earbuds will charge inside the charging case in 57 minutes.
3. 2 HD mics per bud. Clear Voice Technology is only applicable when the microphone is being used to record voice, e.g. taking a call or recording a voice message, and reduces ambient noise for the microphone.
4. CMF Buds 2a's earbuds have been tested under controlled laboratory conditions to IP54 rating in accordance with IEC 60529 (international) standards, but the charging case is not supported. Splash, water and dust resistance may decrease over time as a result of normal wear. It is recommended to avoid using the earbuds during extreme sports to prevent damage from sweat penetration. Do not charge a wet device or charge the device in moist environments. Do not submerge the device completely underwater or expose it to any liquid other than fresh water, such as seawater, chlorinated water or drinks. If the device has been immersed in water or the speaker is wet, sound may not be heard clearly.
5. Latency can be reduced to as low as 110 ms when the buds are paired with Nothing phone devices, with Game Mode turned on.
6. Before use, please open the charging case to trigger a new device pairing or reconnection. Fast Pair will be available on all supported Android devices running Google Play services 11.7+ with compatibility back to Marshmallow (Android 6.0), while Find My and device renaming support is available from Android 10 onwards.
7. Custom controls need to be turned on with a phone. For devices that are Nothing OS 1.5.6 and above, these functions can be set up in the phone settings by entering the Bluetooth interface. For other devices Android 6.0 and above, or iOS devices 13 and above, you can download and install the Nothing X app to set these up. CMF Buds 2a allows customisable controls triggered by double tap, triple tap, tap & hold, and double tap & hold. Customisable functions are next song, previous song, volume up, volume down, voice assistant and switching between Noise Cancellation Modes.
8. Default settings are defined by Nothing. For non-Nothing smartphone users, please download the Nothing X app for more operations. This is available for download on Google Play and iOS App Store. Historical and personal data are managed in accordance with our Privacy Policy. For Nothing OS users, all device settings and customisations are already integrated into Nothing OS version 1.5.6 and higher. All users must update the Nothing X app in Google Play Store before using to ensure all features are up to date.
9. CMF Buds 2a has passed multiple restricted substance tests (including EU RoHS, REACH, etc.), as well as skin irritation and sensitivity tests, to ensure that every substance that comes into contact with the skin has been thoroughly evaluated. Please keep the product clean when wearing it. If your skin develops redness, itching, swelling, or other discomfort after contact with the product, please stop using it immediately and consult a doctor. Few people may have special reactions to specific materials. This may be caused by sweat and humidity in confined spaces, fungal infections, weather, environmental factors, long-term contact with irritants such as soap or sweat, and other factors. If you know you have allergic symptoms or other sensitive reactions, please note that the product contains the following materials: nickel, acrylates, and cyclosiloxanes.
