These headphones can be used to listen to music and answer calls, and are well suited for use with smartphones, MP3 players, tablets, and other portable devices.

The HD 4.40 BT are built to be portable and can make travel more pleasurable.

Their robust, foldable-headband design can be easily and compactly stored in the supplied protective case.

Control at Your Fingertips
If you want to take or make a call, change a track, or adjust the volume, the intuitive earcup-mounted controls—along with the integrated microphones—allow for easy operation of the headphones.
High-Quality Sound with No Strings Attached
These wireless headphones are about freedom, musically and physically—thus, no cable. Instead, to appropriately complement the Sennheiser speakers, this headset comes with state-of-the-art wireless technology, aptX audio codec for reliable transmission and true wireless Hi-Fi sound, and provides immediate and simple pairing with compatible devices via Near Field Communication (NFC).
