Refined style and sound. The HD 1, a winning combination of uncompromised performance, pure minimalistic style and luxurious high-quality materials, such as genuine leather ear cups, has now gained even more appeal by becoming the HD 1 Wireless Over-Ear. The hybrid active NoiseGard™ attenuates ambient noise, while the highdefinition aptX® codec carves out every aural nuance in finest detail. Furthermore, the built-in VoiceMax microphone enables you to conduct crystal clear conversations.

HD 1 without Limit

The new Sennheiser HD 1 Wireless lets you experience crystal-clear HD 1 sound without being attached to a cable. It combines high-resolution sound with a lightweight, puristic design and exclusive materials like stainless steel and real leather.

Our developers have combined the wireless freedom that you crave with our perfect signature HD 1 sound that you love.

High-resoluting and Deep-reaching

While the hybrid active NoiseGard™ attenuates ambient noise, the high-definition aptX® codec carves out every aural nuance in even finer detail. Thus, the trademark HD 1 sound becomes still more brilliant. Furthermore, the VoiceMax microphone, as an integral part of the headphones, enables you to conduct crystal-clear conversations without the need of an external microphone.

Experience a whole new quality in wireless sound. With the new HD 1 Wireless. Its large diaphragms and innovative technology deliver full HD 1 sound in new perfection. Clear, richly detailed and with a powerful bass.

Advanced and Smart

With the HD 1 Wireless setting up a wireless connection is even easier than to plug in a conventional cable. It is implemented via the integrated NFC™ at the push of a button. In an instant, thanks to Bluetooth® 4.0 standard. Connect and enjoy the sound.

Timeless and Immaculate

Love of detail is a main character trait of the Sennheiser HD 1 Wireless: With sliders made of stainless steel, and luxurious leather covering the soft, newly designed ear cushions. Its sound and its finish with accurately placed seams make the HD 1 a delight for all senses.

Without a cable the HD 1 becomes even more puristic, reduced to the max - maximum listening pleasure.

Comfortable and Variable

The ear cups of the new HD 1 Wireless are attached to high-end ball joints running steplessly in collapsible sliders made of brushed stainless steel. The individual adjustment to the head is important for both comfort and sound. And with its newly designed ear cups the HD 1 offers even more wearing comfort.

Thanks to high-quality materials the mechanical components of the Sennheiser HD 1 Wireless are especially durable and elegant.

Optional and Optimized

The new HD 1 Wireless can also be operated with a cable, just like any conventional headphones. The design of the jack plug, however, is not conventional at all: Its especially low profile was optimized for the use on mobile devices.

Fitted with jack plugs on both ends, the cable is completely detachable and can be replaced if necessary.
