Buying wireless earbuds under ₹2,500 can feel like walking through a maze.
Every brand claims “deep bass,” “strong ANC,” and “long battery.” But once you start using them, reality often looks different. Weak noise cancellation. Battery draining fast. One earbud stopping randomly. App not connecting.
That is exactly where cmf by nothing buds 2a enters the picture.
At ₹2,449, it promises 42 dB Smart Active Noise Cancellation, a large 12.4mm driver, Ultra Bass Technology 2.0, 35.5 hours battery life, Bluetooth 5.4, dual device pairing, and IP54 protection. On paper, it looks like a serious contender in the budget ANC segment.
But specs do not matter if real-world usage disappoints.
In this detailed cmf by nothing buds 2a review, I will explain everything in simple terms. Sound quality, bass performance, ANC strength, call clarity, comfort, battery life, connectivity, and whether it is actually worth buying in 2026.
Another reason the cmf by nothing buds 2a is attracting attention is its positioning in the market. It sits in a very competitive price bracket where buyers expect more than just decent sound. At ₹2,449, people want ANC, strong bass, stable connectivity, and reliable battery life in one package.
That expectation creates pressure on brands. When a product tries to deliver all these features together at this price, it deserves careful evaluation. This review focuses on whether those promises actually translate into real daily performance rather than just impressive marketing lines.
Let’s break it down clearly so you can decide confidently.
Experience powerful 42dB ANC, deep 12.4mm bass and up to 35.5 hours of playback with the CMF by Nothing Buds 2a at just ₹2,449.

Here are the important specs in a simple format:
Key Specifications | |
|---|---|
| Driver Size | 12.4mm dynamic driver |
| Bass Tech | Ultra Bass Technology 2.0 (adjustable) |
| Tuning | Dirac-tuned audio |
| ANC | 42 dB Smart Active Noise Cancellation |

Now let’s move beyond specs.
When looking at specs, it is important to understand how they work together. For example, a large 12.4mm driver combined with Dirac tuning suggests that the brand is not only chasing loud bass but also controlled sound balance.
Similarly, Bluetooth 5.4 paired with dual-device connectivity indicates a focus on modern usability. Individually, each feature sounds good. But collectively, they suggest that the cmf by nothing buds 2a is designed for practical, everyday users who multitask across devices and environments.

Detailed Review of CMF by Nothing Buds 2a
Sound Quality
Sound is the main reason anyone buys earbuds.
The cmf by nothing buds 2a comes with a 12.4mm driver, which is quite large for this price. A larger driver usually means better air movement. That directly affects bass depth and overall sound fullness.
In simple terms, music feels bigger and more energetic.
It also comes with Dirac tuning. Dirac is an audio technology brand that focuses on sound correction. What that means for you is cleaner audio balance. Vocals feel more defined. Instruments do not overlap too much.
Now let’s talk about bass.
Ultra Bass Technology 2.0 allows you to adjust bass levels. That is important. Some people love heavy bass. Others prefer balanced sound. This feature lets you fine-tune according to your taste.
For example:
- Listening to EDM at the gym? Increase bass.
- Watching a podcast? Reduce bass slightly for clearer vocals.
- Listening to classical music? Keep it balanced.
In daily use, the cmf by nothing buds 2a delivers punchy bass without drowning vocals. It feels lively rather than flat.
For ₹2,449, the sound performance is impressive and competitive.
Another important aspect is volume handling. Some budget earbuds distort when you increase volume above 70 percent. Distortion means the sound becomes harsh or unclear when played loudly. With the cmf by nothing buds 2a, the larger driver helps maintain stability at higher volumes.
That means you can increase volume during workouts or travel without the audio becoming muddy. Still, for long-term ear health, it is always better to listen at moderate levels, especially when ANC is already reducing outside noise.
Design and Comfort
Design matters more than we admit.
The orange color option stands out. It does not look boring. It feels modern and bold. The finish mixes matte and glossy elements, which gives it a premium touch for the price.
The earbuds are lightweight and ergonomic. That means they are shaped to sit naturally inside your ears.
Fit plays a huge role in sound quality and ANC performance. If the earbuds do not seal properly, bass reduces and outside noise leaks in. The ergonomic design of the cmf by nothing buds 2a helps create a proper in-ear seal for most users.
Choosing the right ear tip size is essential. A proper fit improves comfort, enhances bass response, and strengthens ANC effectiveness. Spending a few minutes testing different ear tips can significantly improve overall experience.
Comfort during long use?
Yes, they are comfortable for extended sessions like:
- Watching a 2-hour movie
- Attending long online classes
- Listening to music during travel
The seal is decent, which also helps passive noise isolation.
There is also a lanyard hole on the case. That may sound small, but it adds practicality. You can attach it to a bag or key loop.
IP54 rating means protection against dust and light splashes. Safe for workouts and light rain.
Battery Life and Charging
Battery is one of the strongest points of cmf by nothing buds 2a.
Total battery life is 35.5 hours with the case.
In practical terms:
If you use them 2–3 hours daily, you may charge the case once or twice a week.
Fast charging is impressive.
10 minutes charge gives 5.5 hours playback.
That is huge in this price segment.
Imagine you forgot to charge overnight. Plug in for 10 minutes while getting ready, and you are sorted for the day.
Full case charging takes 89 minutes, which is reasonable.
Battery anxiety is almost eliminated here.
Battery longevity over months of use is also important. Frequent full discharges and constant fast charging can affect battery health over time in any electronic device.
The strong battery backup of the cmf by nothing buds 2a reduces the need for constant charging cycles. Because the case offers extended hours, you are less likely to push the battery to zero daily. That indirectly supports healthier battery life over the long term.

Connectivity and Controls
Bluetooth 5.4 is the latest version here.
What does that mean?
- More stable connection
- Less random disconnection
- Better power efficiency
In daily use, pairing is quick and smooth.
Dual-device pairing is another big advantage. You can connect the cmf by nothing buds 2a to your laptop and phone at the same time.
For example:
Watching YouTube on laptop and suddenly get a call on your phone? It switches smoothly.
This feature is very useful for students and office users.
Touch controls are responsive. You can manage music, calls, and ANC modes easily.
Dual-device pairing is particularly useful in hybrid work situations. Imagine working on a laptop and attending meetings while also keeping your phone connected for personal calls.
Instead of manually disconnecting and reconnecting every time, the cmf by nothing buds 2a handles switching more smoothly. This reduces small daily frustrations, which might seem minor but significantly improve long-term satisfaction.
Active Noise Cancellation (ANC)
The cmf by nothing buds 2a offers 42 dB Smart ANC.
Let’s simplify that.
ANC uses microphones to detect outside noise and create opposite sound waves to cancel that noise.
42 dB is strong for this price.
Smart ANC means the system adjusts noise cancellation based on surroundings. While it may not be as advanced as premium flagship earbuds, it still adapts reasonably well between indoor and outdoor environments.
For example, at home it mainly suppresses fan noise, while outdoors it reduces low-frequency traffic sounds. This adaptability makes the cmf by nothing buds 2a practical for mixed usage rather than limited to a single environment.
In real-world use:
- Fan noise reduces clearly.
- Traffic hum reduces noticeably.
- Café background chatter softens.
Is it flagship-level ANC? No.
But for under ₹2,500, it performs better than many competitors.
Based on user review data, one user rated noise cancellation 3/5, which suggests that while good, it may not block everything in very noisy environments.
Still, for commuting and daily use, it works effectively.
Call Quality
The cmf by nothing buds 2a includes 4 HD microphones with AI-powered Environmental Noise Cancellation (ENC).
ENC focuses on improving your voice during calls.
In real life:
Indoor calls are clear.
Outdoor calls are manageable in moderate traffic.
One user rated mic quality 4/5, which aligns with expectations for this segment.
If you attend office calls or online classes, it performs reliably.
AI-powered ENC works by identifying your voice pattern and reducing background noise digitally. It does not completely remove loud background chaos, but it prioritizes your voice in the audio stream. In real-life usage, this means your voice remains clear even when mild environmental noise exists.
For students attending online classes or professionals joining virtual meetings, this reliability adds real-world value to the cmf by nothing buds 2a.
Real User Feedback Analysis
Looking at Indian reviews:
Positive feedback highlights:
- Strong bass
- Good value for money
- Solid battery life
- Decent sound quality
However, there are some negative reviews mentioning:
- One earbud stopped working
- App pairing issues
- Battery draining fast in some cases
This tells us something important.
Most users are satisfied, but quality control consistency may vary in rare cases. That happens in budget segments across brands.
If you buy, always test within the return window.
Honest reviews build trust, and it is important to acknowledge both sides.
It is also worth noting that negative reviews in budget electronics often highlight either isolated defects or usage misunderstandings. For example, pairing issues sometimes occur due to not resetting the earbuds properly before first use.
That does not invalidate complaints, but it adds context. Evaluating user feedback helps form a balanced view of the cmf by nothing buds 2a, rather than relying solely on promotional material.
