Headphone· $200· 2026-07-28Sennheiser HD 505
Sennheiser's best entry open-back yet — and a top end that lands differently on every head.

IEM· $1300· 2026-07-19Sennheiser IE 900
Sennheiser's single-driver flagship pairs some of the best bass in any IEM with a midrange the graphs — and its listeners — keep arguing over.

Headphone· $99· 2026-07-17Sennheiser HD 280 Pro
Two million sold, two different headphones under one name, and one long argument about whether it is flat.

- Headphone· $500
Sennheiser HDB 630
Everyone agrees it measures right. The argument is whether 'right' is the same thing as worth listening to — and whether $500 buys enough over the half-price Momentum 4.

Sennheiser HD 25
The 1988 broadcast tool DJs adopted by accident — and still argue about, octave by octave.
