Choose your must-haves

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 2 Plus

What it brings

Nothing rates 14 hours per charge and 61.5 hours with the case using AAC with ANC off, or 7.5 and 33 hours with ANC on.
Manufacturer source
It supports LDAC and dual connection, and its Personal Sound profile, powered by Audiodo, is built from a pure tone audiometry hearing test.
Manufacturer source

What to check

The case charges over USB-C only; no wireless charging is listed, and LDAC works only with supporting Android phones and cuts rated playback to 5.5 hours with ANC on.
Manufacturer source
The earbuds are IP55, but Nothing's own page is inconsistent about the case (IPX2 in the table, not water-proof rated in the footnote).
Manufacturer source

Beyerdynamic AVENTHO 300

What it brings

Supported codecs are AAC, aptX Lossless, aptX Adaptive and LE Audio, so a phone or computer that supports one of these can use it instead of a basic connection.
Manufacturer source Manufacturer source
A rated 50 hours with ANC on, 10-minute quick charging for 5 hours and a supplied hard case and 3.5 mm cable suit long trips.
Manufacturer source Manufacturer source

What to check

SBC is not in beyerdynamic's codec list, and the sources do not say whether the USB-C port can carry audio.
Manufacturer source Manufacturer source
beyerdynamic does not state the test conditions (source, volume) behind the 50-hour battery figure, so real runtime may differ.
