AI Verdict
These are 12mm LCP driver earbuds with 50dB ANC and 61.5 hours of total playback, best for users prioritizing extended battery life and high-res audio on a budget.
These earbuds offer strong features like 50dB ANC and 61.5 hours of battery life, making them a fit for noise reduction and extended use. However, the potential for slippage during heavy sweat and the bass-heavy default sound profile mean they aren't a perfect fit for everyone without some user adjustment.
If you need a more secure fit for high-intensity activities, look for earbuds with ear hooks or wing tips, or those with a higher IP rating like IP67 or IP68.

What Buyers Say
The CMF Buds 2 Plus really stand out for their battery life, giving you a massive 61.5 hours total, which is way more than most earbuds in this price range. The 50dB ANC is also a big win, cutting out a lot of background noise effectively. While the sound has punchy bass and Hi-Res audio, you might need to tweak the EQ in the app to get it just right, as some users found the default a bit too bass-heavy. Call quality is okay in quiet spots, but voices can sound a bit off in noisy environments.
“Honestly, these Buds 2 Plus are pretty sick for the price, the ANC actually works and the battery just keeps going, but man, the bass is a bit much out of the box and my calls sound weird on the bus.”
Common Praise
- The 50dB active noise cancellation works well for blocking out environmental sounds.
- The 61.5-hour total battery life means you rarely have to worry about charging.
- Hi-Res Audio with LDAC support provides a richer listening experience.
- The IP55 rating makes them suitable for gym sessions and outdoor activities.
- Personalized sound profiles via Audiodo calibration are a thoughtful addition.
Common Complaints
- Call quality can be 'boxy' and less clear in loud or windy conditions.
- The default sound signature is bass-heavy, requiring EQ adjustments for a balanced sound.

Ownership Tips
- You'll probably spend some time in the Nothing X app dialing in your preferred EQ settings to get the sound just right.

- If you don't have a Nothing phone, you're missing out on some of the cooler, advertised features like the super-low latency.
- The personalized hearing test actually makes a noticeable difference in audio clarity.

Buying Guide
When you're looking at earbuds, don't just focus on the price. Think about how you'll actually use them. If you're always on noisy commutes, strong Active Noise Cancellation (ANC) is key. For long trips, battery life matters a lot. And if you're picky about how your music sounds, look for features like Hi-Res Audio and customizable EQ. Don't forget about durability if you're planning to sweat or be outdoors.
50dB ANC
This number tells you how much external noise the earbuds can cancel out. 50dB is a significant amount, meaning less airplane hum or office chatter gets through, like turning down the volume on the world around you.
61.5 Hours Playtime
This is the total listening time you get with the earbuds and their charging case combined. It's like having a super-sized fuel tank for your music, letting you go for days without needing an outlet.
12mm LCP Drivers
The driver size (12mm) indicates the speaker's diameter inside the earbud, generally meaning it can move more air for richer bass. LCP (Liquid Crystal Polymer) is a material choice that helps deliver clearer, more precise sound across different frequencies.
IP55 Certification
This rating tells you how well the earbuds are protected against dust and water. IP55 means they're protected against dust ingress and low-pressure water jets from any direction, so they can handle sweat and light rain without issues.
Alternatives
If these don't fit, look for earbuds with a higher IP rating for more extreme water resistance, or those with a more neutral default sound profile if you dislike heavy bass and prefer not to use an app for EQ adjustments.
