Sennheiser HDB 630
Ten rigs agree it measures close to neutral. Reviewers still split three ways on what that sounds like — and owners add a quieter argument about volume, fit and staying power.

Sennheiser HD 25
The DJ booth's default for thirty years — unbreakable in reviews, fixable in practice, and argued over from bass to clamp.

Sennheiser HD 800 S
The soundstage-and-detail benchmark that measures lean and bright — agreed on for space, comfort and resolution, argued over for its treble, its tonality and its $2,000 price.

Sennheiser HD 620S
Sennheiser's first closed-back 6-series — it measures close to target, isolates well and sounds wide for a closed-back, yet whether its bass, mids and treble land depends on your ears, your seal and how much you love the open HD 600.

Sennheiser IE 200
Tiny, comfortable and tuned close to the modern target — if the tip covers the hole in the nozzle, and the cable survives you.

Sennheiser HD 600
Twenty-nine years as the hobby's yardstick — natural, honest and light, with a bass and a stage people still argue about.

Sennheiser HD 550
An HD 600-grade midrange in a featherweight 500-series shell — if its lower treble and its headband both happen to suit you.

Sennheiser MOMENTUM 4 Wireless
Reviewers love the sound and everyone loves the battery. The arguments are over bass that some call boomy, noise cancelling that splits the room in half, and an owner record of creaks and failures.

Sennheiser IE 900
Sennheiser's single-driver flagship has bass nearly everyone rates among the best in any IEM — and a hollowed-out midrange, and a service record, that split its owners.

Sennheiser HD 650
Hi-fi's most-recommended open-back — and the one its owners least agree on.

Sennheiser HD 599
Comfort nobody argues with, a mid-bass hump everybody does — the open-back that made and lost friends for a decade.

Sennheiser MOMENTUM 5 Wireless
Sennheiser finally fixed the noise cancelling. What reviewers still can't agree on is the bass, the top end, and whether $400 is a bargain or a stretch.
