Product Information

Inspired by People with Momentum

The new HD 1 In-Ear Wireless Headphones combine sleek design, immaculate sound performance, and take-anywhere mobility. This premium neckband headset made of luxurious, high-quality materials, offers exceptional Hi-Fi wireless sound assured by Bluetooth 4.1 and Qualcomm apt-X. With NFC for simple one-touch pairing, an integrated microphone, and a ten-hour battery life, it is the perfect companion to mobile devices.

Some people live for sound. They go further than others - to where nobody has ever been. They do things that nobody else has done before them. And redefine the boundaries of sound. They have MOMENTUM. Together with a group of talented artists, Sennheiser developed the MOMENTUM project.

A New Way to Experience HD 1

Enjoy wireless freedom and unadulterated in-ear sound reproduction the HD 1 way: Ultra soft sheepskin nappa leather stitched onto the neckband. Precision milled stainless steel sound tunnels, mirrored chrome finish on the earpieces, tough, impact-resistant polycarbonate elements. And, of course, the fabulous sound and state-of-the-art wireless technology to match.

That’s the new HD 1 In-Ear Wireless Headphones.

Precisely What You Want to Hear

Well-conceived in every detail, the HD 1 In-Ear Wireless Headphones provide a rich, uncompromised experience. For superior acoustic precision, the stainless steel in-ear sound tunnels have been custom-machined. The high-quality dynamic speaker system delivers the signature HD 1 sound effortlessly: powerful bass response, detailed vocal projection, and a great sound stage.

Refined Wireless Technology

Free from cables, full of great sound. Thanks to Bluetooth 4.1, AAC codec support, and Qualcomm apt-X compatibility, the HD 1 In-Ear Wireless Headphones offer true transparent Hi-Fi sound, so you can experience your music to the full with all the freedom of cableless listening, while NFC one-touch pairing ensures immediate connectivity to smart devices.

Intuitively Yours

The neckband of the HD 1 In-Ear Wireless Headphones not only looks great, it also harbors a handy three-button remote and high-quality microphone, making it easy to stay connected and manage phone calls and control music on the go. The headset supports convenient multi-connection with up to 2 devices at once. Voice prompts notify you of the pairing-status and provide battery life warnings. Vibration alert for incoming calls and the support of USB audio with USB charging round up this comprehensive ease-of-use package.

Tailor-Made for Your Ears

A snug fit is crucial for in-ear buds. Thus, no less than four different sizes can be found in the ear-adapter set of the HD 1 In-Ear Wireless Headphones, guaranteeing maximum wearing comfort, excellent attenuation, and secure fit.

Out-of-Home Excellence

Made from tough high-quality materials, the HD 1 In-Ear Wireless Headphones are designed for the road. With batteries able to deliver 10 hours of legendary Sennheiser sound on one single charge and featuring 1.5 hour fast USB charging, you can go a long way. The included premium hard shell carrying case will protect your headset when it's not in use.

Attractive Ergonomics

The sleek and robust ergonomic around-the-neck design of the HD 1 In-Ear Wireless Headphones allows for comfortable all-day listening. With signature HD 1 details such as earpieces with a mirrored chrome finish and ultra-soft sheepskin nappa leather stitched onto the neckband, they offer luxury craftsmanship deserving of the unique HD 1 sound signature.
