CMF BY NOTHING CMF Buds 2a Wireless Earbuds Active vs TOZO NC9 Hybrid Active Noise Cancelling

Design and build quality

The CMF BY NOTHING CMF Buds 2a feature a stylish and ergonomic design that has been refined over years of development. They are described as lanyard-ready, suggesting a focus on portability and active lifestyles. The build includes an IP54 rating, providing confirmed protection against dust and water splashes. In contrast, the TOZO NC9 headsets are ergonomically designed to fit snugly in the ears. While the TOZO model emphasizes a secure fit for all-day wear, the provided data does not specify an IP rating for water or dust resistance. The CMF model holds an advantage in documented build durability due to the explicit IP54 certification.

Sound quality and drivers

Audio performance is driven by different technologies in each model. The CMF Buds 2a utilize studio-grade 12.4mm Bio-fiber drivers co-tuned with DIRAC, a renowned audio provider for luxury vehicles. This combination aims to provide a warm soundstage with rich mids and crisp bass. The TOZO NC9 features built-in 10mm drivers paired with exclusive OrigX Acoustic 2.0 sound technology. This technology is designed to deliver deep, rich bass and precise audio clarity. While the TOZO drivers are smaller, the proprietary acoustic technology aims to enhance the overall experience for music and movies. The CMF model offers larger drivers and a recognized audio tuning partner.

Noise cancelling performance

Active Noise Cancelling (ANC) is a key feature for both earbuds. The CMF Buds 2a offer 42dB Smart Active Noise cancelling, which is tailored for common daily listening scenarios. Users can adjust settings with Off or Custom options. The TOZO NC9 boasts a Hybrid Active Noise Cancelling system with a maximum noise reduction depth of 45dB. This higher decibel rating suggests a potentially deeper isolation from the outside world, allowing users to focus on music without distractions. While both models offer ANC, the TOZO NC9 claims a higher maximum reduction depth on paper.

Microphone and call clarity

Communication quality relies on microphone arrays and noise reduction technology. The CMF Buds 2a employ Quad HD ENC mics equipped with Clear Voice Tech and Wind Noise Reduction 2.0. This setup is designed for crystal-clear communication wherever the user is located. The TOZO NC9 utilizes a 6 Microphone Call system with ENC Ambient Noise Reduction. This system actively filters out background sounds to ensure clear call quality even in noisy environments. With six microphones compared to the quad setup on the CMF, the TOZO model provides a higher count of hardware dedicated to capturing voice and reducing ambient noise.

Connectivity and compatibility

Modern connectivity standards are crucial for seamless pairing and stability. The CMF Buds 2a are equipped with Bluetooth 5.4, delivering a secure connection. They also support Fast Pair features for both Google and Microsoft ecosystems, enabling quick switching between devices. The provided product data for the TOZO NC9 does not specify the Bluetooth version. While they function as wireless earbuds, the lack of specified version information places the CMF model ahead in terms of documented connectivity standards. The CMF advantage lies in the confirmed Bluetooth 5.4 specification and broad fast-pair compatibility.

Comfort and fit

Both manufacturers prioritize ergonomics to ensure the earbuds can be worn for extended periods. The CMF Buds 2a come with multiple in-ear headphone tips to ensure comfort for all ear shapes, celebrating design accolades for comfort. The TOZO NC9 headsets are designed to fit snugly and include a choice of six sizes of replaceable tips. The specific mention of six sizes for the TOZO model offers a quantifiable metric for fit customization. However, both products emphasize ergonomic design intended for all-day wear, making comfort a competitive category where both offer substantial inclusion of tip sizes.

Price and value

Value is determined by the features offered relative to the cost. The CMF BY NOTHING CMF Buds 2a are priced at $43.02. They offer premium features like DIRAC tuning and Bluetooth 5.4. The TOZO NC9 is priced at $26.57, which is significantly lower than the CMF model. Despite the lower price, the TOZO model offers higher claimed ANC depth and more microphones. For budget-conscious consumers, the TOZO NC9 presents a compelling value proposition by delivering core features like hybrid ANC and transparency mode at a lower cost entry point compared to the CMF alternative.

Which one should you buy?

Choosing between these models depends on prioritizing build specs versus cost efficiency. If confirmed durability with an IP54 rating and the latest Bluetooth 5.4 connectivity are your primary concerns, the CMF Buds 2a are the suitable choice. They also offer larger drivers and recognized audio tuning. However, if your main goal is to maximize value and noise cancellation performance per dollar, the TOZO NC9 is the winner. It offers a higher ANC depth of 45dB, more microphones for calls, and a transparent mode at a significantly lower price point, making it the practical choice for most users.
