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.

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 it brings and what to check

Beyerdynamic DT 770 PRO

What it brings

The closed-back design gives about 18 dBA of passive noise attenuation, and its dynamic driver with bass-reflex system is rated 5–35,000 Hz at 80 ohms.
Manufacturer source Manufacturer source Manufacturer source
A 3.5 mm plug with a screw-on 6.35 mm adapter covers both common headphone sockets, and the ear and headband pads can be replaced by the owner.
Manufacturer source Manufacturer source Manufacturer source

What to check

The supplied straight cable is 3 m long.
Manufacturer source Manufacturer source Manufacturer source
It weighs 375 g with the cable and is built for a firm professional fit; beyerdynamic's pages give the headband pressure as about 3.5 N in one place and 3.5–5.5 N in another.
Manufacturer source Manufacturer source Manufacturer source

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).
