How did this happen? 
This new headset was designed after the requirements of demanding listeners who are not content to just hear their music on the go, but want to enjoy it, no matter where. So Sennheiser developed NoiseGard™ active noise cancellation – the power to eliminate any noise that could come between you and your music, which the HD 4.50 Wireless delivers to you in the renowned Sennheiser sound.

Only your music gets in your ears
When you enjoy the sound of the HD 4.50 Wireless, you enjoy the sound of your music. Period. The rest of the noisy world will be shut out by NoiseGard™, the active noise cancellation developed by Sennheiser. Thus, you can indulge in the refined sound reproduction of this great close-back headset: The rich details, the vividness and the powerful bass – brought to you by proprietary Sennheiser drivers.

Great sound with no strings attached
The HD 4.50 Wireless is about freedom – musically and physically. Thus, no cable. Instead, to appropriately complement the Sennheiser quality speakers, this headset comes with state-of-the-art wireless technology and audio codec for reliable transmission and true wireless Hi-Fi sound. While immediate and simple pairing with compatible devices is ensured by Near Field Communication (NFC). 

Use your intuition
Everything about the HD 4.50 Wireless is well-conceived. Just get your fingers at the intuitive ear-cup mounted controls and you will feel what we mean. Together with the integrated microphones they make taking and making calls, changing tracks or adjusting the volume a breeze.

Comfort on every street
Streetwise, the HD 4.50 Wireless combines supreme comfort and maximum portability. With its around-ear design and deep, ergonomically designed ear pads it allows you to enjoy the most extended of listening sessions. While its robust foldable headband design can be neatly stowed away in the included protective case.

The joy of a long-lasting battery
Being out and about often means being apart from proper power outlets. Fortunately, the battery of the HD 4.50 Wireless lets you enjoy NoiseGard™-protected music for up to 19 hours (it lasts up to 25 hours with NoiseGard™ switched off).

Spectacular within, minimalistic without
If you develop a premium headset like the HD 4.50 Wireless a short-lived show look is not an option. We chose a sleek frame made of high-quality materials. Timelessly elegant. Making it a pleasure to behold, as well as to use – for many years to come.
