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.

SELECTED TOPIC

Microphone

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

Samsung Galaxy Buds3 FEYes

Manufacturer specification · Samsung lists 6 microphones in total, with a pre-trained machine learning model that filters noise on calls.

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.
