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.

FEATURES SIDE BY SIDE6 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC

Microphone

A built-in microphone matters for calls and voice chat. An audio-only headphone connection does not supply a microphone channel.

Nothing Ear (3a)Yes

Manufacturer specification · Three microphones per earbud (six in total) with Clear Voice Technology for calls; the buds also support call recording and Audio Snapshot where available.

Source 1

Beyerdynamic DT 900 PRO XNo

Manufacturer specification · Supplied cables end in a stereo headphone jack; no microphone is listed.

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

Nothing Ear (3a)

What it brings

Nothing rates up to 10 hours per charge and 42 hours with the case using AAC with ANC off, or 6 and 25 hours with ANC on.

Pinching the buds can record calls or save up to a minute of what you are hearing (Audio Snapshot), which is then managed in the Nothing X app; call recording depends on region.
Manufacturer source

What to check

The case charges only over USB-C according to the specification, with no wireless charging listed.
Manufacturer source
LDAC cuts the rated figures to 4.5 hours per charge and 20 hours with the case with ANC on, and dust and water resistance is IP54.
Manufacturer source

Beyerdynamic DT 900 PRO X

What it brings

A 48-ohm nominal impedance and a rated 100 dB SPL at 1 mW mean it is specified for use with laptops, tablets and phones as well as studio interfaces.
Manufacturer source Manufacturer source
The single-sided cable detaches at a mini-XLR connector and can be replaced by cables of different lengths and connection options; the ear pads and headband pad are also replaceable.
Manufacturer source Manufacturer source

What to check
