CMF BY NOTHING Buds 2 Wireless Earbuds ANC Review: The Budget ANC King with a Surprising Punch

There’s a specific kind of frustration that builds when the world refuses to be quiet. For me, it was the daily train commute. The screech of the wheels, the cacophony of a dozen overlapping conversations, the tinny leakage from someone else’s headphones—it was a relentless assault on my focus and sanity. I tried cranking up the volume on my old, non-ANC earbuds, but that only led to ringing ears and a lingering headache. I craved a personal bubble of silence, a way to reclaim my auditory space and dive into a podcast or a focus playlist without the world intruding. The problem? Most earbuds offering truly effective Active Noise Cancellation (ANC) came with a price tag that made my wallet weep. The search was on for a pair that could deliver genuine peace and premium sound without demanding a premium price. This journey is what led us to test the very promising CMF BY NOTHING Buds 2 Wireless Earbuds ANC.

What to Know Before You Buy Noise Cancelling Earbuds

A Noise Cancelling Headphone set is more than just an item; it’s a key solution for reclaiming your personal soundscape in an increasingly loud world. Whether you’re trying to concentrate in a busy open-plan office, find tranquillity on a turbulent flight, or simply immerse yourself fully in your favourite music, ANC technology is designed to electronically filter out unwanted ambient noise. The primary benefit is a dramatically improved listening experience where you can hear every detail without dangerously increasing the volume. This not only enhances audio fidelity but also contributes to better hearing health over the long term. It’s about creating a personal oasis of sound, wherever you happen to be.

The ideal customer for this type of product is someone facing daily auditory distractions. This includes commuters, frequent flyers, students studying in noisy dorms or libraries, and office workers seeking to block out chatter. They value both audio quality and the ability to focus. However, these might not be the best fit for those who need to maintain full awareness of their surroundings for safety, such as cyclists or runners on busy streets (though many models, including these, offer a “Transparency Mode” as a workaround). Extreme audiophiles who demand lossless, high-resolution audio codecs and studio-grade neutrality might also look towards more specialized, and significantly more expensive, wired options. For them, the convenience of wireless and ANC might take a back seat to pure, unadulterated sound reproduction.

Before investing, consider these crucial points in detail:

• Fit & Comfort: This is arguably the most critical factor for earbuds. A poor fit not only causes discomfort during long listening sessions but also severely compromises the effectiveness of ANC. Look for earbuds that come with multiple sizes of silicone or foam tips to ensure you can create a perfect seal in your ear canal. The weight and shape of the buds themselves also matter; a lightweight, ergonomic design will prevent ear fatigue.
• Audio & ANC Performance: Don’t just look at the decibel (dB) number for ANC. Consider the breadth of the frequency range it can cancel. A high dB rating is great for low-frequency rumbles like engine noise, but its effectiveness against higher-frequency sounds like voices can vary. For audio, look at the driver size (larger often means better bass), driver material, and any special tuning or software enhancements like Dirac Opteo, which aims to balance the sound profile.
• Build Quality & Durability: Your earbuds will likely face daily wear and tear. A robust charging case is essential for protection and portability. For the buds themselves, an IP rating (Ingress Protection) is crucial, especially if you plan to use them for workouts. An IP55 rating, like the one on the CMF BY NOTHING Buds 2 Wireless Earbuds ANC, indicates strong resistance to both dust and water jets, ensuring they can handle sweat and light rain with ease.
• Battery Life & Connectivity: Check the battery life for both the earbuds on a single charge and the total life with the charging case. Consider your typical usage patterns to see if they match up. For connectivity, look for modern Bluetooth standards (like 5.2 or higher) for a stable connection and features like multi-device pairing, which allows you to seamlessly switch between two devices, like a laptop and a phone, without re-pairing.

Getting these factors right ensures you find a pair of earbuds that don’t just sound good, but integrate perfectly into your life. You can see how these features stack up on the CMF Buds 2 and decide if they meet your personal criteria.

While the CMF BY NOTHING Buds 2 Wireless Earbuds ANC is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing the CMF BY NOTHING Buds 2: First Look and Feel

Our first impression upon unboxing the CMF BY NOTHING Buds 2 Wireless Earbuds ANC was one of minimalist confidence. The packaging is clean and straightforward, reflecting the brand’s design-forward ethos without any unnecessary waste. We received the Dark Grey model, and the charging case immediately stands out. It’s a compact, squarish puck with a matte finish that feels pleasant to the touch and resists fingerprints well. As one user noted, the case material does feel a “little cheap” compared to premium offerings from Apple or Sony, but it simultaneously feels “robust enough for day to day use,” a sentiment we share. It’s lightweight plastic, but the hinge feels secure and the magnetic snap that pulls the earbuds into their charging slots is satisfyingly firm.

The earbuds themselves are nestled securely inside. Their design is a comfortable stem-style, feeling a touch larger than AirPods Pro but exceptionally lightweight. The initial pairing was, as another user described, “painless and quick.” We simply opened the case near our Pixel 8, and a prompt appeared instantly. The process was just as smooth on an iPhone after downloading the Nothing X app. The box includes a short USB-C charging cable and two extra sets of silicone ear tips (small and large), complementing the pre-fitted medium ones. This attention to fit is critical, and we immediately appreciated the option to tailor the seal. The overall initial experience is one of simplicity and thoughtful design that belies its budget-friendly price point, and you can check the latest price and availability right here.

A Deep Dive into the CMF Buds 2’s Real-World Performance

Specs on a page are one thing, but the true test of any earbud is how it performs in the chaos of daily life. We put the CMF BY NOTHING Buds 2 Wireless Earbuds ANC through its paces for over a week, using it for commuting, workouts, long work sessions, and casual listening. We tested its sound signature across multiple genres, challenged its ANC in noisy environments, and relied on its microphones for important calls. What we discovered was a product that consistently over-delivers on its promises, setting a new benchmark for what’s possible in the budget-friendly audio space.

Sound Signature: Dirac Opteo and Ultra Bass 2.0 in Action

Out of the box, the sound profile of the CMF Buds 2 is immediately engaging. Powered by an 11mm PMI driver and tuned with Dirac Opteo, the audio is clear and well-balanced, but with a definite emphasis on the low end. This is thanks to the “Ultra Bass Technology 2.0,” and it is no mere marketing gimmick. As one user enthusiastically noted, the “bass is surprisingly deep,” and we wholeheartedly agree. On tracks like Billie Eilish’s “bad guy,” the sub-bass is rich and resonant without becoming muddy or overwhelming the vocals. It’s a fun, energetic sound that makes pop, hip-hop, and electronic music truly shine.

However, as another user insightfully pointed out, this bass-forward approach can be less ideal for “guitar based rock, folk, etc,” where it can sometimes overpower the mids. This is where the Nothing X app becomes an indispensable tool. The app provides a robust equalizer, allowing you to tame the bass and boost the higher frequencies. We found that with a little tweaking, we could achieve a much more neutral sound. One reviewer mentioned the “treble could be a little crisper,” and by using the EQ, we were able to add that desired sparkle to cymbals and hi-hats in classic rock tracks. This level of customization is a standout feature at this price point. It transforms the earbuds from a one-size-fits-all product to something that can be tailored to your specific taste, a feature that truly sets it apart.

The 48 dB Hybrid ANC: A Shield Against the Daily Grind?

Let’s be clear: the Active Noise Cancellation on the CMF BY NOTHING Buds 2 Wireless Earbuds ANC will not completely silence the world in the same way a pair of flagship Sony or Bose headphones might. One user correctly observed that the noise isolation is “not as good as the XM1004s etc, but it is good.” And “good” is exactly the right word—in fact, for this price, it’s astonishingly good. The 48 dB of noise reduction is most effective against low-frequency, constant drones. On our train commute, the deep rumble of the engine was reduced to a faint hum, making podcasts and audiobooks perfectly clear without needing to max out the volume. In a bustling café, it effectively muted the background chatter and the whir of the espresso machine, creating a productive bubble of focus.

The key to maximizing the ANC performance, as a wise user pointed out, is getting the right fit. We found the pre-fitted medium tips were slightly too small, creating a weak seal. Switching to the included large tips made a night-and-day difference. Suddenly, the passive noise isolation improved, and the active cancellation had a much stronger effect. The Nothing X app also offers an “Environmental Adaptive” mode that adjusts the ANC level in real-time, which we found worked surprisingly well when moving from a quiet street into a loud subway station. The Transparency Mode is also well-implemented, allowing you to hear your surroundings clearly for conversations or announcements without a strange, artificial sound. This level of ANC performance makes the daily grind significantly more pleasant and is a key reason to consider these impressive earbuds.

Call Quality and Connectivity: The Unsung Heroes

Often overlooked in reviews, call quality and connectivity are crucial for a daily-driver set of earbuds. CMF has equipped the Buds 2 with a formidable array of six HD microphones combined with AI-powered Clear Voice Technology. We tested this by taking calls while walking down a windy street, a notoriously difficult scenario for earbud mics. The results were impressive. The person on the other end reported that our voice was clear and prioritized, with the wind noise being significantly suppressed. This makes them a reliable choice for both personal calls and professional video conferences on the go.

The connectivity is equally robust. We experienced zero dropouts or stuttering issues during our testing, though we noted one user had to return their pair for this reason, suggesting occasional quality control issues might exist. The multi-device pairing is a game-changer for productivity. We had the CMF BY NOTHING Buds 2 Wireless Earbuds ANC connected to our laptop and smartphone simultaneously. When a call came in on the phone while we were listening to music on the laptop, the earbuds switched over automatically and seamlessly. The touch controls are responsive and, crucially, customizable within the app. We set up a double-tap for track skipping and a triple-tap to summon our voice assistant, and it worked flawlessly every time. It’s these quality-of-life features that elevate the Buds 2 from just a pair of headphones to an essential everyday tool.

All-Day Endurance and Durability

The advertised 55-hour total battery life is a headline feature, and in our experience, it’s not an exaggeration. With ANC on, we got just over 7 hours of continuous playback from the earbuds themselves. With ANC off, that stretched to well over 10 hours. Combined with the charges stored in the case, we went through an entire work week of moderate use—including commutes, a few gym sessions, and several hours of focused work each day—without ever needing to plug in the case. This epic endurance removes any battery anxiety and makes them perfect for travel or for those who are simply forgetful about charging their devices.

Furthermore, the IP55 dust and water resistance rating provides genuine peace of mind. We wore them during several intense, sweaty workouts and even got caught in a light drizzle on a run. The earbuds didn’t miss a beat. This durability means you don’t have to baby them; they are built to be a part of your active life. This combination of marathon battery life and robust build quality solidifies the CMF BY NOTHING Buds 2 Wireless Earbuds ANC as a reliable workhorse, ready for whatever your day throws at it. It’s a level of dependability that we rarely see in products at this competitive price point, making them an excellent investment for long-term use.

What Other Users Are Saying

The general consensus among users is overwhelmingly positive, with most feedback centering on the incredible value for money. One detailed review perfectly captured this sentiment, stating, “Very impressive for the money! I’ve got quite a few pairs of headphones… value wise, these are brilliant.” Many, like the user who bought them to replace broken AirPods Pro, found them to be “excellent for the money,” praising the painless pairing and good sound quality. The deep bass is a recurring point of praise, with one person rating it a “9/10.”

However, the feedback isn’t universally perfect, and it highlights some important considerations. Several negative reviews have nothing to do with the product’s performance but rather with fulfillment issues. Users reported receiving products that were “scuffed up and dirty,” missing accessories, or in one shocking case, an “empty box.” While this seems to be a seller or shipping problem rather than a defect in the product itself, it’s a valid concern for any online purchase. On the performance side, a user who experienced a “stuttering issue” had to return their pair, indicating that while our unit was flawless, isolated defects can occur. These points serve as a reminder to purchase from a reputable source with a good return policy.

How Does the CMF BY NOTHING Buds 2 Compare to the Competition?

While the CMF BY NOTHING Buds 2 Wireless Earbuds ANC shines in the budget category, the audio market is vast. Understanding where it sits in relation to other options—both within its family and in higher price brackets—is key to making an informed decision.

1. Bowers & Wilkins Pi8 True Wireless Noise Cancelling Earbuds

Placing the Bowers & Wilkins Pi8 next to the CMF Buds 2 is a study in market segmentation. The Pi8 is a premium, audiophile-grade offering for those who prioritize sound fidelity above all else and have a budget to match. It boasts a 24-bit wireless connection with aptX support, delivering a level of detail and clarity that the CMF Buds 2, with its more consumer-focused tuning, can’t replicate. The build quality is also in another league, using premium materials for a luxurious feel. You should choose the B&W Pi8 if your primary goal is critical listening and you want one of the best-sounding true wireless earbuds on the market, period. The CMF Buds 2 is for everyone else who wants great performance without the exorbitant price tag.

2. CMF BY NOTHING Buds Pro 2 Wireless Earphones

This is the most direct competitor and the logical step-up within the CMF family. The CMF BY NOTHING Buds Pro 2 offers an upgrade in key areas, most notably its more powerful 50 dB Smart Active Noise Cancellation. For users who find themselves in extremely noisy environments frequently, that extra 2 dB of cancellation could make a meaningful difference. It also promises enhanced “HiFi sound,” suggesting a potentially more refined audio experience. The choice here comes down to a simple cost-benefit analysis. If you love the CMF value proposition but need the absolute best noise cancellation the brand offers and are willing to pay a small premium, the Buds Pro 2 is the better pick. If the already-impressive ANC of the Buds 2 is sufficient for your needs, you can save some money and be perfectly happy.

3. Sonos Ace Wireless Bluetooth Headphones

The Sonos Ace represents a different form factor entirely: over-ear headphones. This is not a direct competitor in terms of portability but is an alternative for those seeking noise cancellation for different use cases. The Ace will almost certainly provide superior comfort for long-haul flights or all-day desk use, as over-ear designs distribute pressure more evenly. It also offers features like Spatial Audio with Dynamic Head Tracking and seamless integration with the Sonos home theatre ecosystem. You should choose the Sonos Ace if your primary use case is at home or in the office, you prioritize long-term comfort over pocketability, and you are invested in the Sonos ecosystem. The CMF Buds 2 remains the undisputed choice for on-the-go listening, exercise, and ultimate portability.

Our Final Verdict: Are the CMF BY NOTHING Buds 2 Wireless Earbuds ANC Worth Your Money?

After extensive testing, we can say with confidence that the CMF BY NOTHING Buds 2 Wireless Earbuds ANC are not just good for the price; they are simply a fantastic pair of wireless earbuds, full stop. They manage to pack in a feature set—effective hybrid ANC, stellar battery life, a highly customizable sound profile, and a durable, workout-ready design—that is genuinely shocking to find in this price bracket. The sound is fun and bass-forward out of the box but can be easily tailored to your liking, and the call quality is clear and reliable.

Of course, they aren’t perfect. The ANC can’t compete with flagship models that cost four times as much, and the plastic case feels built for function over fashion. But these are minor compromises in what is otherwise an outstandingly well-rounded package. We would wholeheartedly recommend the CMF Buds 2 to students, commuters, gym-goers, and anyone looking for a high-performance daily driver that delivers on all fronts without emptying their bank account. They prove that you no longer need to spend a fortune to get a premium audio experience. If you’re ready to upgrade your daily listening with a product that punches far above its weight, you can find the best deal on the CMF BY NOTHING Buds 2 Wireless Earbuds ANC right now.
