In a market flooded with wireless earbuds, finding a pair that delivers strong performance without breaking the bank can feel like a challenge. Enter the CMF Buds 2a—a budget-friendly option from Nothing’s sub-brand that promises features typically reserved for more expensive models. With hybrid active noise cancellation, powerful bass, and clear call quality, all wrapped in a sleek and sporty design, the CMF Buds 2a are designed to meet the needs of modern listeners—whether you're commuting, gaming, or working out. But do they live up to the hype, or are they just another affordable pair with compromises? Let’s dive into the full review to find out.
The CMF Buds 2a Wireless Earbuds are a powerful blend of premium features packed into an affordable price point. Equipped with 12.4mm bio-fiber dynamic drivers, these earbuds are tuned with Dirac sound technology and enhanced by Ultra Bass Technology 2.0, making them a bass lover’s dream. Whether you’re listening to EDM or a podcast, the sound is punchy, detailed, and engaging.
One of the standout features is the 42dB Hybrid Active Noise Cancellation (ANC), capable of filtering out background noise up to 2900Hz — from the bustle of subway stations to chatty open offices. And for those moments when you need to hear your surroundings, the Transparency Mode toggles on easily, letting in ambient noise without removing the earbuds.
Communication is crystal clear thanks to four HD microphones powered by Clear Voice Technology and Wind Noise Reduction 2.0. Whether you're on a call during a windy jog or in a noisy café, your voice remains sharp and undistorted.
Designed for active lifestyles, the CMF Buds 2a are IP54 rated, meaning they're resistant to dust, sweat, and light rain. Their dual-texture ergonomic design ensures a secure, comfortable fit during workouts, while the lanyard-ready charging case adds a touch of portability for users on the move.
When it comes to power, they offer 8 hours of playback (up to 35.5 hours with the case). Plus, with quick charging, just 10 minutes of charge gives you up to 5.5 hours of playback without ANC—ideal for last-minute power-ups.
Additional smart features include Low Latency Mode for gaming, custom EQ and ANC tuning through the Nothing X app, cross-device syncing with Nothing products, and even ChatGPT voice assistance for hands-free control.
The CMF Buds 2a are competitively priced at $39.00 in the US, offering premium features typically found in more expensive earbuds, making them a standout option in the budget segment.

The CMF Buds 2a strike an impressive balance between affordability and performance. For under $40, users get rich bass, intelligent noise cancellation, and versatile usability across devices. The bass-heavy tuning may overshadow mid and high frequencies in some tracks, which audiophiles might find limiting. However, the custom EQ settings via the Nothing X app help mitigate this issue by letting users personalize their sound profiles.
The ANC is effective for general noise like traffic or chatter but may not fully isolate high-pitched or complex sounds like high-speed fans or screeching brakes. Still, for casual and fitness-focused use, it’s a highly capable performer.
The ergonomic fit ensures comfort even during extended use, and its durability makes it reliable for sports and travel. The low-latency mode is particularly useful for mobile gaming, reducing delay between action and sound.
If you’re on a budget but don’t want to compromise on core features like ANC, audio quality, and battery life, the CMF Buds 2a are an excellent choice. They’re well-suited for casual music listening, workouts, and everyday calls. Audiophiles or users looking for more balanced sound may need to fine-tune the EQ, but for the price, it’s hard to argue with what’s on offer.
The CMF Buds 2a pack premium features—like Hybrid ANC, a powerful bass profile, and long battery life—into a sleek, budget-friendly package. While not perfect, they excel in most areas that matter for everyday users. At just $39, they are one of the best bang-for-your-buck earbuds in 2025. Whether you’re commuting, gaming, or working out, the Buds 2a deliver reliable, customizable, and enjoyable audio at a fraction of the cost of flagship alternatives.
