Sennheiser HD 4.40 BT Bluetooth Headphones

Sennheiser – the name stands for the establishment and development of trends. We do not just react, we are always reinventing the future. Here our passion goes to such lengths that we are only satisfied with a solution when we see it as being perfectly adapted to the needs of the given case. So the trailblazing ideas of our developers have made Sennheiser products famous throughout the world, and repeatedly met with an enthusiastic response from audio aficionados. Our achievements have won us numerous international awards: two innovation prizes of German industry, the ‘technical Oscar’ (the Scientific and Engineering Award), a Grammy and the most significant television prize in the USA, the Emmy Award.

The Sennheiser HD 4 Series – Let everyday sound great
Take your music with you, anywhere. Versatile and vibrant, the new HD 4 series comprises the complete Sennheiser quality package in a range of durable, closed-back, over-ear headsets that redefine the quality of sound.

Strong ties that will free you
The HD 4.40 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.

Control is all at your fingertips
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 4.40 BT all this is actually fun. Have a try

Comfort to make you feel at home – everywhere
The HD 4.40 BT was made to go places with you – and make these places more pleasurable. With its around-ear design and deep, ergonomically designed ear pads it offers comfort even during extended listening sessions. Its robust foldable headband design that can be easily and compactly stored in the supplied protective case makes for perfect portability.

Style as clean as the sound
Elegantly minimalistic – using tough, high-quality materials: That is how the HD 4.40 BT was designed. Its sleek frame not only makes it more comfortable to wear, it also makes a statement of timeless class.
