THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Nothing CMF Buds 2a

What it brings

  • They include Adaptive ANC, Transparency mode, dual connection and find my earbuds support.
    Manufacturer source
  • Each earbud weighs 4.28 g and the case 42.75 g, and the case has a lanyard hole for carrying.
    Manufacturer source

What to check

  • Rated playback is 8 hours per charge and 35.5 hours with the case with ANC off, falling to 5 and 23 hours with ANC on.
    Manufacturer source
  • ANC is rated to 42 dB over up to 2900 Hz, calls use four microphones (two per earbud), the listed codecs are AAC and SBC, and the IP54 rating covers the earbuds but not the charging case.
    Manufacturer source

Nothing Ear (3)

What it brings

  • For calls, each earbud has three MEMS microphones and a voice pickup unit that senses vibrations from your jawbone, and the case holds Super Mic: two beamforming MEMS microphones you switch to with the case's Talk button, which Nothing recommends holding about 5 cm from your mouth in loud places.
    Manufacturer source
  • The case charges both over USB-C and wirelessly, and with AAC Nothing rates up to 10 hours per charge (ANC off) and 38 hours with the case.
    Manufacturer source

What to check

  • Using LDAC cuts rated earbud playback to 3.5 hours with ANC on (5.5 hours off), against 5.5 and 10 hours with AAC.
    Manufacturer source
  • Dust and water resistance is IP54, and Nothing says turning on dual connection affects Super Mic behaviour, so the two features do not fully work together by default.
