CMF by Nothing Buds 2

Package Contents

Inside the box, you’ll find the CMF by Nothing Buds 2, a charging case, three sizes of silicone ear tips, and a multilingual quick-start booklet. The documentation also contains safety information and pairing instructions, although no German translation is included – users will need to understand English at a minimum.

Minimalist Design & Robust Build

True to CMF’s style, the Buds 2 feature a minimalist look with the same colour for earbuds, ear tips, and charging case, creating a cohesive visual impression. The earbud housings have a smooth finish, while the antenna stems are matte for added contrast.

With IP55 certification, they are resistant to dust and water jets. CMF also claims the Buds 2 have passed multiple drop, temperature, and humidity tests. The compact, sturdy charging case does not feature the “Smart Dial” found on some other CMF models.

Technical Details

The 11 mm dynamic drivers deliver CMF’s Ultra Bass Technology, which detects bass content in the audio and optimises its reproduction to avoid resonance or boominess. The hybrid ANC offers up to 48 dB noise reduction up to 5.2 kHz and includes an Environmental Adaptive Mode that dynamically adjusts cancellation strength based on ambient noise levels.

Wireless connectivity runs via Bluetooth 5.4 with SBC and AAC codec support, but no high-resolution codec options. Multipoint connectivity allows pairing with two devices simultaneously, and fast pairing works with Google and Microsoft devices.

Clear Bass & Speech

Thanks to six integrated microphones and Dirac Opteo processing, the Buds 2 offer clear, rich bass and optimised voice clarity during calls, with background noise filtered out effectively.

Comfort & Touch Controls

Each earbud weighs just 4.5 g, contributing to a secure yet comfortable fit, supported by three ear tip sizes. The ergonomic design makes them suitable for extended listening sessions.

Touch controls allow you to manage music, calls, and ANC mode switching easily. Charging is via USB-C, with a fast-charge option inside the case. Battery life reaches up to 55 hours with ANC off, aided by in-ear detection to conserve power.

Smart Features & AI Integration

The CMF companion app supports firmware updates, EQ adjustments, ANC settings, and touch control customisation. A fit test uses audio playback to ensure a proper seal, and there’s also a “find my earbuds” function.

CMF advertises “ChatGPT integration”, but in practice, this is only available with CMF or Nothing smartphones. Otherwise, pressing the touch control launches your device’s default voice assistant (e.g., Google Assistant or Perplexity.ai).

How does the CMF by Nothing Buds 2 sound?

The CMF by Nothing Buds 2 deliver deep, punchy bass even without Ultra Bass enabled. When active, bass impact increases significantly without overwhelming the midrange, which remains clear and transparent. High frequencies are detailed without harshness.

The soundstage is well-layered, with precise transient response, making them suitable for music, gaming, and film. A dedicated low-latency mode improves synchronisation for gaming. Distortion remains minimal even at higher volumes, and isolation is strong enough for focused listening at lower levels.

Conclusion

The CMF by Nothing Buds 2 deliver on most of their promises for Hi-Fi enthusiasts seeking an affordable, feature-rich pair of in-ears. They impress with clear sound, smart features, and versatile usage scenarios, from music and gaming to movies. Bass lovers in particular will appreciate their tuning.

While the lack of high-resolution codec support, wireless charging, and Smart Dial may disappoint some, their excellent value for money makes the CMF by Nothing Buds 2 a strong recommendation in the budget True Wireless segment.
