CMF Buds 2 powered by Dirac Opteo
Dirac Opteo digitally enhances the sound in your earbuds, unlocking their full potential and providing an optimised listening experience based on patented correction technology.
Leveraging years of insight from Dirac Live’s unique mixed-phase impulse response correction, Opteo uses advanced measurement-based correction technology to remove any unintended resonances or sound colourations, maximising the acoustic performance of the headphones. It not only provides you with high-definition sound but also makes the vocals richer and the bass deeper.

Spatial Audio Effect is built based on the Head-Related Transfer Function (HRTF) model. It creates cinematic-grade 3D spatial sound, providing a fully immersive listening experience with omni-directional sensation in the ear canal without limitations on audio sources, allowing users to enjoy a cinema-grade experience at any time. Please download the Nothing X app for configuration.

The actual result may differ based on device settings, environment, usage and other factors.

AAC:
- Playback with ANC off:
- up to 55 hours with case
- up to 13.5 hours with buds only
- Playback with ANC on / Transparency Mode:
- up to 32 hours with case
- up to 7.5 hours with buds only

Talk Time:
- Talk time with ANC off:
- 35 hours with case
- 8.5 hours with buds only
- Talk time with ANC on / Transparency Mode:
- 30 hours with case
- 7 hours with buds only

Test Conditions**: Measured under AAC mode at 50% volume. Charging and battery tests are based on internal results from Nothing’s labs (25°C or 77°F). Actual battery life may vary depending on volume, frequency, output source, environmental interference, product features used, and usage habits. Actual experience will depend on individual use.

When the earbuds are in an unconnected and unworn state, they will enter an auto power-off mode after 60 minutes (this duration may vary between products). To reactivate them, you need to manually place the earbuds back into the charging case.

If the earbuds remain idle after being fully charged, they will enter a fully charged power-off state after 2 minutes.

The earbuds charge until the charging case falls below 1% battery. However, when the charging case has nearly depleted, the indicator LED won't turn on, and the charging case button won't respond. Please recharge the charging case promptly in this case.

CMF Buds 2 series can store records for up to 8 devices at maximum capacity.

Once the CMF earbuds is paired with your device, you can use a single earbud. Please note, the initial pairing can only be done with both earbuds.

CMF Buds 2 series feature Ultra Bass Technology. The algorithm dynamically detects low-frequency signals in music, enhancing the perception of low frequencies in real time to deliver a more powerful and dynamic bass experience. Users can also dynamically adjust the low-frequency intensity based on their listening preferences in the Nothing X app, defining their own high-definition bass experience. Additional options available in the Nothing X app.

Adaptive Mode monitors the noisiness of your environment and adjusts the noise cancellation accordingly, for the optimum audio experience.
