The cult $30 studio headphone everyone recommends with an asterisk — big bass and a big stage for the money, a treble lift every rig confirms, and plastic that doesn't always last.

The cheapest door into Sennheiser's 600 series — now closed, and still arguing about its treble.

Thirteen measurement rigs agree it is quiet at both ends. Reviewers split on whether that is restraint or absence.

Focal's analogue nearfield with the beryllium tweeter: praised everywhere for detail, stage and bass, measured low in distortion — and heard as silky by most, a little hot by some.

The best-measuring dongle of its day, argued over for its price, its voice and the word "self-developed".

A $350 twelve-track sequencer for small hybrid rigs — agreed on its value, size and generative tricks, split on whether its screenless, alt-key workflow ever stops being a puzzle, on how readable its white-on-white grid is, and on how rough its launch firmware was.
The dictionary
A boost in the bass and lower mids that gives music a rich, cozy, easy-on-the-ears character.
The perceived three-dimensional space of a recording — how wide, deep, and tall the sound appears.
An emphasis on the upper midrange and treble — vivid, clear, and sometimes sharp.
An even-handed sound with no part of the spectrum pushed forward or held back — balanced and reference-like.
