What Buyers Say
Many users are surprised by the audio quality, especially the deep bass, which can be a bit much out of the box but cleans up nicely with EQ adjustments in the Nothing X app. The ANC is a standout feature, effectively cutting out a lot of background noise, making commutes much quieter. However, some found the transparency mode to be on the weaker side, and call quality in loud areas isn't always crystal clear. The battery life is consistently praised as a major advantage.
“Okay, so the bass is kinda wild at first, but once I tweaked it in the app, these things sound amazing for the price. ANC actually works, like, really works on my commute, but don't expect perfect calls on a windy street. Battery life is insane though, I barely charge the case!”
Common Praise
- Big, punchy bass that can be tuned for clarity.
- Clear mids and crisp highs after adjusting the EQ.
- Strong active noise cancellation, effective in busy environments.
- Comfortable and lightweight for extended wear.
- Excellent battery life with fast-charging capabilities.
- Seamless dual-device pairing and in-ear detection.
Common Complaints
- Default bass-heavy sound profile can make some music sound muddy.
- Transparency mode volume is lower than expected.
- Voices during calls can sound 'boxy' in loud surroundings.
- Earbuds can become slippery and lose secure fit during heavy sweating.
- Limited functionality of gaming mode and ChatGPT integration outside of Nothing phones.
Ownership Tips
- The rotating loop on the charging case, while visually unique, doesn't serve a practical function.
- The 'Personal Sound' feature using Audiodo genuinely tailors the audio to individual hearing, making a noticeable difference.
- The matte finish on the case feels premium but can show fingerprints over time.
- Firmware updates through the Nothing X app have improved performance and added features since launch.
- The earbuds maintain a stable Bluetooth 5.4 connection even with dual-device pairing.
Frequently Asked Questions
Do these earbuds support Hi-Res Audio?
Yes, the CMF Buds 2 Plus are Hi-Res Audio certified and feature LDAC-certified 12mm LCP drivers for high-fidelity sound.
How long does the battery last?
You get up to 14 hours of playback per earbud with ANC off, and a total of 61.5 hours with the charging case. With ANC on, it's about 7.5 hours per earbud and 33 hours total with the case.
Are they waterproof for sports?
The earbuds have an IP55 rating, meaning they are resistant to dust and water jets, making them suitable for workouts and light rain.
Can I customize the sound?
Yes, you can customize the sound profile using the Nothing X app, which includes a custom EQ and Audiodo personalized hearing calibration.
Does the ANC work well?
The Smart Adaptive ANC provides up to 50dB of noise cancellation across a 5400Hz range, effectively blocking background noise, especially high-frequency sounds.
Buying Guide
When looking at earbuds, you're balancing sound quality, how well they block out noise, and how long they last. For these, the 'Hi-Res Audio' means you're getting a wider range of sound details, like listening to a high-quality recording versus a compressed MP3. 'Adaptive Noise Cancelling' means the earbuds actively listen to your surroundings and adjust how much noise they block, so you don't have to fiddle with settings. Battery life is crucial; the stated hours include both the earbuds themselves and the extra charges you get from the case.
12mm LCP Drivers
These are the tiny speakers inside the earbuds. Larger drivers, like these 12mm ones, generally move more air, which can result in deeper bass and a fuller sound, similar to how a bigger speaker cone in a home stereo produces more impactful sound.
50dB Adaptive Noise Cancelling (ANC)
This number tells you how much external noise the earbuds can actively cancel out. 50dB is a significant amount, meaning they can make a noisy train or office feel much quieter, like turning down the volume on the world around you. 'Adaptive' means it adjusts automatically to your environment.
61.5 Hours Playtime
This isn't just how long the earbuds last on one charge, but the total listening time you get by recharging them multiple times using the battery in their carrying case. It's like having a portable power bank for your earbuds, letting you go days or even weeks without needing to find a wall outlet.
IP55 Certification
This rating indicates the earbuds' resistance to dust and water. The first '5' means they're protected against most dust ingress, and the second '5' means they can withstand low-pressure water jets, so they're fine for sweaty workouts or getting caught in the rain, but don't dunk them in a pool.
Alternatives
If these don't quite fit, look for earbuds with a dual-driver setup for more nuanced audio separation, or those with higher IP ratings (like IPX7 or IPX8) if you need full submersion protection for swimming. For superior call quality in all environments, consider models that specifically highlight advanced voice pickup technologies beyond just multiple microphones.
