Sennheiser HD1 IN-EAR HEADPHONE // Black-Chrome

The true dimensions of the Sennheiser In-Ear Headphones can be measured not only by their uncompromising sound, but also in a wealth of little details - from the nano-precise, stainless-steel sound tunnel to the three-button multifunction remote with integrated microphone.

The design of the In-Ear Headphones speaks a clear, consistent language. Over 200 contrasting red stitches grace the black-lacquered zipper on the soft-covered case that safely protects your earbuds. The black-and-red cable leads to a red, high-gloss housing. And the outstanding design also extends to their fit, with comfortable tips that sit just right.

There's only one way to deliver uncompromising sound in a small package: by combining top-quality materials with superior craftsmanship. That's why the acoustic components contain no plastic. They are made of high-quality stainless steel, manufactured using precision milling technology. It's not a difference you can see - but one you'll hear in the powerful yet nuanced sound signature.
