CMF Buds 2 Plus Review: Best Budget Earbuds Under £50?
Unbeatable Value in Budget Wireless Earbuds
Searching for true wireless earbuds under £50 that don't sacrifice critical features feels impossible—until now. After analyzing extensive hands-on testing, I confirm the CMF Buds 2 Plus deliver exceptional value at £49. While the standard Buds 2 (£39) are competent, the Plus model solves key pain points with personalized audio tuning and enhanced noise cancellation. As a tech analyst, I've compared dozens of budget models, and these stand out by packing premium features into an affordable package. Let's break down why they're worth your attention.
Design and Build Quality
Both models share a lightweight, IP55-rated build that survives accidental drops and exposure to dust or rain—uncommon at this price. The twistable lanyard disc on the charging case offers tactile satisfaction, though the matte finish on the Plus version feels slightly more premium.
The earbuds themselves use practical plastic to hit this price point. While not luxurious, their ergonomic shape ensures secure fit during runs or workouts. Color options differ: the standard Buds 2 come in vibrant orange, while the Plus offers blue or Apple-inspired white.
Features and App Experience
Connectivity shines through the Nothing X app, enabling:
- Dual-device pairing
- Customizable touch controls
- Spatial audio support
- LDAC high-res audio mode (requires compatible phone)
The touch controls are a notable weakness. Tapping the top of the earbud drives them deeper into your ear canal—an uncomfortable design flaw during frequent adjustments. Sensitivity works well, but physical buttons would solve this issue. Still, features like in-ear detection and wind noise reduction 3.0 exceed expectations for sub-£50 earbuds.
Audio Performance and ANC
Here’s where the Plus model justifies its £10 premium:
| Feature | CMF Buds 2 | CMF Buds 2 Plus |
|---|---|---|
| Drivers | 11mm PMI | 12mm LCP |
| Max ANC | 48dB | 50dB |
| Personal Sound | ❌ Not available | ✅ Hearing test customization |
| Bass Adjustment | 5-level ultra boost | ✅ Personalized profile |
The 50dB active noise cancellation effectively muffles rumbles like train noise, though street chatter still penetrates. The game-changer is the Plus model's hearing test—it creates a custom sound profile by assessing your auditory response to frequencies. After decades of clubbing left me with high-frequency hearing loss, this feature balanced my audio perfectly. You won't find this on earbuds costing twice as much.
Battery Life and Microphones
Both models deliver astonishing endurance:
- 13-14 hours playback (ANC off)
- 10 hours with ANC + LDAC enabled
- Case provides 40-55 extra hours
Microphones impressed during testing. Even with simulated traffic noise blasting nearby, voice pickup remained clear on calls. The six-mic array outperforms many mid-range competitors.
Why the Plus Model Dominates
The £10 upgrade isn't optional—it's essential. Beyond specs, the personalized sound profile adapts to your hearing biology, something typically reserved for £150+ earbuds. While compromises exist (plasticky build, awkward controls), no other sub-£50 model offers this feature set.
Final Verdict and Alternatives
For £49, the CMF Buds 2 Plus are a revelation. They’re ideal if you prioritize:
- Customized audio compensating for hearing quirks
- Legitimate ANC for commutes
- Marathon battery life
- Rugged, water-resistant design
Skip the standard Buds 2 unless £10 is non-negotiable. Consider spending more only if premium materials or flawless controls are dealbreakers.
Pro Tip: Enable LDAC in the Nothing X app for noticeable clarity gains if your phone supports it.
