A closed-back studio headphone that most sources — eight measurement rigs, two labs, the studio and audiophile press and most owners — call one of the best-balanced closed-backs available: close to neutral with a sub-bass lift, a relaxed upper midrange and treble, little urge to EQ, and an unusually open sound for sealed cups. Comfort is the near-universal highlight (272 g, low clamp, soft hybrid pads that work with glasses), and isolation is good for a passive closed-back though it lets low rumble through. Opinion splits on the bass: the rigs agree it is deep and plentiful below 100 Hz, and most reviewers hear it as tight and well judged, but a sizeable minority hears it as soft, sub-heavy and short on mid-bass punch — a gap the measurements trace to a dip around 180 Hz and to a seal that glasses or hair can break. Build also divides: serviceable and built to last for most, light plastic that feels cheap for $399 (with hinges one lab calls a weak point) for others. Smaller camps find the relaxed treble a little dark or soft and the price high against cheaper closed-backs like the FiiO FT1, and the long coiled cable is the most common gripe.
About this product
The closed-back studio headphone Sennheiser's professional division launched in April 2026 — a sealed-cup counterpart to the open-back HD 490 PRO, built on the same 38 mm driver chassis and the same light, glasses-friendly frame. Sold as the HD 480 PRO (soft bag) and the HD 480 PRO Plus (travel case); the two are acoustically identical. Not the open HD 490 PRO, the consumer-division HD 620S, or the 1990s HD 480 of the same name.
Sennheiser's HD 480 PRO is the closed-back sibling of the well-liked open-back HD 490 PRO: the same 38 mm driver chassis and the same light, glasses-friendly frame, but with sealed cups aimed at tracking, monitoring and working in rooms where open headphones would leak. It arrived in April 2026 at $399 (the Plus version adds a travel case for $40 more), from the professional half of Sennheiser rather than the consumer brand that makes the HD 620S.
Six months on it has become one of the most-recommended closed-backs around — measurement sites, studio magazines and audiophile reviewers mostly agree on its balance and comfort. The arguments that remain are narrower: whether its sub-bass-heavy low end feels punchy or soft, whether its light, mostly plastic build feels right at the price, and whether its relaxed treble is a virtue or a little too polite.
