Beyerdynamic is a German audio manufacturer founded in 1924 by Eugen Beyer and based in Heilbronn — one of the oldest headphone makers — known for its hand-assembled studio headphones and microphones.

Beyerdynamic filed down the treble spike and built it like a tank — then the rigs found a 4 kHz notch and owners found the headband glue.

A gaming-and-studio favourite with a vast stage and a famous treble spike — thrilling, fatiguing or a quick fix, depending on whose ears.

Tank-built, fast and hard-hitting — wrapped around an 8 kHz peak that every rig measures and listeners love, fix or send back.

The 8 kHz peak was narrowed, not tamed — and whether that is “finally manageable” or “still Beyer” is the whole review.

The closed Beyer grew a bass shelf and lost its impedance — and reviewers still can't agree whether the treble got fixed.

Beyerdynamic's closed-back studio workhorse: tank-built and phone-drivable — but reviewers describe its sound like three different headphones.

The tamed Beyer: the flattest of the trio, and the one you either call honest or call boring.

The studio workhorse everyone owns — and everyone argues about its treble.
