These headphones differ in design, sound quality, battery life, connection stability, and additional features such as noise cancellation or touch control. Each model is designed for specific users - from budget options for everyday use to more advanced headphones for music enthusiasts or active users. Below, we will review the main differences between these three models and help you choose the most suitable option for your needs.

CMF Buds 2

The CMF Buds 2 headphones feature an 11mm dynamic driver with Ultra Bass Technology 2.0 for powerful, balanced sound and Dirac Opteo™ audio tuning. Dirac Opteo™ helps even more basic headphones sound like higher-end devices, providing a more enjoyable and professional listening experience.

These headphones feature surround sound and 48dB hybrid ANC. With noise cancellation enabled, they can last up to 13.5 hours, and with the case, up to 55 hours. The headphones feature 6 microphones with advanced noise cancellation technology and are IP55 certified for dust and water resistance. Dual device connectivity and ChatGPT integration are supported.

CMF Buds 2a

The CMF Buds 2a are a more budget-friendly model, featuring a larger 12.4mm bio-fiber driver with Dirac tuning. While they also support Ultra Bass Technology 2.0, this model lacks surround sound or LDAC codec support. The noise cancellation level is rated at 42dB, and the battery lasts up to 8 hours of use with the earbuds and up to 35.5 hours with the case.

There are 4 microphones built in and the resistance class is IP54. They also support dual connectivity and low latency mode, 105 ms latency is only available with Nothing phones when the “Game Mode” is enabled. When using the headphones with other devices, the “Low Latency Mode” mode still works, but the latency may be higher.

CMF Buds 2 Plus

CMF Buds 2 Plus is the most advanced model in this series. They have a 12 mm LCP speaker, support Hi-Res audio transmission via LDAC and surround sound. The sound quality is one of the best in this segment, and 50 dB ANC ensures extremely effective noise cancellation. The battery lasts up to 14 hours, and with the case - up to 61.5 hours. Like Buds 2, this model has 6 microphones, IP55 resistance and ChatGPT integration and dual device connection.

CMF Buds 2 / 2a / 2 Plus comparison

The main differences between the models lie in the audio drivers, ANC capabilities, battery life, additional features such as LDAC, surround sound, or ChatGPT support - the CMF Buds 2 Plus offers the highest quality sound and the most features, the CMF Buds 2 is a balanced mid-range option, and the CMF Buds 2a is a simpler but valuable solution at a lower price.
