Sennheiser HD550 Audiophile Open-Back Headphones

HD550 Open-Back, Over-Ear Audiophile Headphones, by Sennheiser.

Your media is keeping secrets. No, not an encoded bitcoin key or Banksy’s real name — sonic secrets: the faint inhale of a singer, a fretboard squeak, whispered background vocals buried deep in the mix, faraway footsteps in an online game.

The Sennheiser HD 550 headphones are your cheat code to hear them all — in brilliant detail and lifelike presence. And you don’t need a roomful of expensive equipment to access the experience.

Detail & Precision

Lots of mainstream audio products give you the bathtub sound. They call it that because the frequency response curve is shaped like a bathtub. This means you are drowning in bass and treble, vocals are weak, and certain frequencies resonate too loudly.

The HD 550 is the opposite — no gaps or peaks. Instruments don’t get lost in the mix. You can hear everything, and clearly. Deep sub bass reproduces frequencies you feel more than hear. Treble extends far beyond human hearing.

Then there is soundstage. Basically, high-end headphones make it feel like each sound is coming from a specific location. Not just left, right, or centre, but also near and far, in front or behind you. Your ears do this 3D thing in real life, too. And with the right headphones, it works with recordings, games, and soundtracks.

Light & Comfy

The HD 550 design is heavily influenced by feedback from real people, who said, “make it light, make it comfy, and make it sound great.”

Sennheiser have revised the headband, using high-quality synthetic leather and softer foam. With such a low total weight, less clamping force was required. Which in turn allowed the use of soft, comfy ear pads with plush velour.

You get a fit that’s stable but so unobtrusive that even long sessions are no problem. Work, play games, or listen for as long as you like — without pinching, pressure, charging, or pairing.
