Second generation The new Sennheiser Momentum headphones give you the freedom to listen to crystal clear sounds, without being attached to a cable. Now boasting wireless technologies and active NoiseGard noise cancellation, the headphones are perfect for use with your mobile phone, tablet device and MP3 player. Featuring Bluetooth 4.0 + EDR technology, the Momentum 2.0 can stream music directly from compatible devices, releasing CD-quality sounds to your ears for up to 22 hours. You can even control the sounds and calls from your Smartphone with an integrated in-line mic/remote. Combining high-resolution sound with a lightweight, puristic design and exclusive materials like stainless steel and real leather, Sennheiser have created a pair of closed circumaural headphones which can comfortably be enjoyed for many hours. The headband and ear cushions of the Momentum 2.0 are covered in a super-soft breathable Alcantara material, which have also been filled with a special two-layer foam. What's more, the ear cups are attached to high-end ball joints so you can conveniently position the headphones to suit. This makes for easy, laid back listening which you can look forward to after a long days work.
