Sennheiser HD 4.50 BTNC Noise Cancelling Wireless Headphones
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 we gave it our NoiseGard™ active noise cancellation – the power to eliminate any noise that could come between you and your music, which the HD 4.50 BTNC delivers to you in the renowned Sennheiser sound.
Enjoy your musical freedom – unwired and undisturbed. Everywhere. Every day.
The HD 4.50 BT is about freedom of movement. Thus, no cable. Instead you get the latest wireless technology and audio codec with Bluetooth 4.0 and aptX for reliable transmission and true wireless Hi-Fi sound. While Near Field Communication (NFC) ensures immediate and simple pairing with compatible devices.
Want to take or make a call, change a track, adjust the volume? With the intuitive ear-cup mounted controls and the integrated microphones of the HD 4.50 BT all this is actually fun.
Elegantly minimalistic – using tough, high-quality materials: That is how the HD 4.50 BT was designed. Its sleek frame not only makes it more comfortable to wear, it also makes a statement of timeless class.
Being out and about often means being apart from proper power outlets. Fortunately, the battery of the HD 4.50 BTNC lets you enjoy NoiseGard™-protected music for up to 19 hours (it lasts up to 25 hours with NoiseGard™ switched off).
