Make the connection with your music quick and wire-free, with the NFC Bluetooth-equipped Sennheiser HD4.40BT headphones.

Wireless freedom via Bluetooth aptX NFC

Thanks to Bluetooth aptX connectivity you can listen to your music in the highest quality, without the hassle of cables. The aptX system gives a more natural and dynamic performance, creating a sound that's closer to a wired connection than ever before (partnering device must feature aptX compatibility). NFC (Near Field Communication) makes connection to your device possible by a simple swipe.

Class-leading Sennheiser sound
World renowned for their professional and consumer headphones, Sennheiser are one of the best brands in the business. With their closed-back design, the HD4.40BT’s not only block out much of the outside noise but also let you hear every detail from the powerful Sennheiser drivers. Smooth and evenly balanced, the HD4.40BTs work well with all types of music – not just the most bassy.

Long-lasting power
The HD4.40BTs use rechargeable batteries that provide up to 25 hours of playback and recharge in just 2 hours. There's a USB cable for recharging and, with the supplied standard 3.5mm cable, the music can continue even when the batteries are exhausted.

Designed to travel
With a slick folding mechanism, these headphones fold rapidly away when not in use. They're also supplied with a carry case to keep them protected when not in use.

Intuitive control via the ear pieces
An integrated microphone lets you make hands-free calls with your smartphone, while on-ear music controls allow you to adjust the volume, play/pause and skip forward/back through your music.

Get the Sennheiser sound, without the wires, with the impressive HD4.40BT.
