The perfect travel companion
One of the most wonderful reasons to travel, the MM 450-X TRAVEL allows you to enjoy superb music quality while on the road. Connect it wirelessly to your mobile, laptop, iPad or any other Bluetooth®-enabled device and take charge of phone and Skype calls, music or audio books. When you are flying, simply connect the cable provided in the convenient travel case and keep listening.

MM 450-X features NoiseGard™* technology, developed by Sennheiser to remove the annoying background noise that can often be heard in calls made from loud locations. As an added benefit, the headset enhances the latest apt-X®-enabled mobile phones and computers with supreme CD-quality sound reproduction.

Hassle-free listening
A must for travelers, the MM 450-X TRAVEL comes with Sennheiser’s TalkThrough function, which lets you speak to a neighbor or flight attendant without removing the headset. Just press a button and an external invisible microphone lets you hear everything that is going on around you.

MM 450 TRAVEL-X comes with volume and playlist controls integrated on the ear cup. And because the closed-back capsule design of the ear caps enhances passive noise reduction, you can keep your music entirely personal and relax in the knowledge that you won’t be irritating fellow travelers.

    Hearing problems-this is the one for you

    I am a Widex Passion RIC user and I tested so many headphones. Only the Sennheiser 450MM gave me what I needed. Crystal clear sound on the phone and excellent microphone. No feedback on my hearing aids.
