Introduction: Flagship Features at a Throwaway Price
The budget audio market has undergone a silent revolution. Just a few years ago, reliable Active Noise Cancellation (ANC) was reserved for $150+ earbuds. Today, brands like Nothing’s CMF and TOZO are delivering genuinely effective noise-blocking and great sound quality for under $50.
If you are a student or a daily commuter looking for silence without financial stress, which sub-$50 champ should you choose? AdxFly Tech Compare compares the stylish CMF Buds 2 and the feature-packed TOZO NC7 across ANC power, sound profile, and crucial battery life.

1. Active Noise Cancellation (ANC) Performance
Both earbuds punch far above their weight in ANC, but they approach noise cancellation differently.
A. Overall Silence (H3)
The CMF Buds 2 often boasts a powerful, aggressive ANC that can cancel up to 43dB of external noise. This makes it exceptionally good at silencing constant low-frequency sounds like airplane cabin drone or constant AC noise—it’s arguably the best noise reduction under the $50 mark.
The TOZO NC7 uses a highly effective Hybrid ANC system. While its maximum cancellation may be slightly less than the CMF, its performance is incredibly consistent and reliable, creating a comfortable, silent background for music and calls.
B. Transparency Mode (H3)
Both offer a transparency mode (Ambient Mode) to hear your surroundings. The CMF Buds 2, thanks to Nothing’s software experience, often offers a more natural, less digitized sound in this mode.
2. Sound Quality and App Controls
Sound quality is highly subjective, but both deliver clear, enjoyable audio.
A. Sound Profile (H3)
- CMF Buds 2: Tends to offer a lively, balanced, and punchy sound, appealing to a wide consumer audience. The bass is clean and energetic without overpowering the mid-range.
- TOZO NC7: Known for having a slight boosted bass frequency response by default. However, it offers a crucial advantage: the inclusion of a comprehensive in-app EQ, allowing users to customize the sound profile to a more neutral or personalized setting, which is a major win for audiophiles.
B. App Customization (H3)
The TOZO NC7’s app is feature-packed, offering EQ control and other customizations that the CMF app may lack. The CMF Buds 2 relies more on its default tuning and minimalist software.
3. Battery Life, Comfort, and Build
A. Battery Longevity (H3)
The TOZO NC7 is the undisputed battery champion in this comparison, boasting a remarkable 9 hours of playback with ANC enabled on a single charge. The CMF Buds 2 is still excellent at around 6.5 hours, but the TOZO’s endurance is class-leading for travelers. Both provide a strong total playback time (40+ hours) with the case.
B. Durability (H3)
The TOZO NC7 offers a superior IPX6 rating, making it highly water-resistant and suitable for heavy rain and intense workouts. The CMF Buds 2’s IP54 rating is suitable for light splashes and sweat but is less robust.
C. Design (H3)
The CMF Buds 2 wins on style, featuring Nothing’s distinct, sleek, and often colorful (like the popular yellow variant) minimalist design that stands out from the crowd.
Final Decision: Power vs. Style
👉 Choose the TOZO NC7 If:
- Battery life (9 hours ANC) and water resistance (IPX6) are non-negotiable.
- You require a fully customizable EQ to fine-tune the sound profile.
- You need the absolute most effective ANC you can get under $50.
👉 Choose the CMF Buds 2 If:
- Sleek, minimalist style and a lightweight feel are paramount.
- You are already in the Nothing/CMF ecosystem and prefer that aesthetic and software experience.
- You primarily use them for commuting and casual listening.
AdxFly’s Final Word: For the best overall performance, battery life, and durability under $50, the TOZO NC7 offers unbeatable value. However, the CMF Buds 2 is the choice for those who value modern, appealing design and strong ANC in a minimalist package.
