Sennheiser HD1 Red In-Ear Headphones

Luscious listening. This earphone is the smallest member of the HD1 product family. Still, it offers uncompromisingly clear, brilliant and powerful sound like all HD1s, as well as a wealth of valuable quality details – from the nano-precise, stainless-steel sound tunnel to the three-button multifunction remote with integrated microphone.
 

Inspired by people with Momentum
 

• Some people live for sound. They go further than others. They go where nobody has ever been. They do things that nobody else has done before. They redefine the boundaries of sound. They have MOMENTUM. Together with a group of talented artists we developed the MOMENTUM project. Get inspired and check out the artists and their videos.
   

HD1 In-Ear
 

• The true dimensions of the Sennheiser HD1 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.
   

Sleek and sophisticated
 

• The design of the HD1 In-Ear 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.
   

Brilliant and powerful
 

• 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.
   

Adaptable and ergonomic
 

• You can forget about the HD1 In-Ear. With their ergonomic, adjustable angle of 15°, the buds adapt so well to your ears that you’ll forget they are there. Thanks to the extra-small sound tunnel and a choice of four ear sleeves to fit any size ear, all you’ll experience is the pure sound.
   

Functional and durable
 

• The range of In-Ear accessories is as broad as the In-Ear itself is tiny. Including a sturdy hard-shell case, intuitive remote for iPhone and Android, elliptical cable that minimizes tangling and sound loss, gold-plated jack and integrated hands-free microphone.
