With one headset, you can listen to music wired or wirelessly, take calls over Bluetooth, cancel 90% of ambient noise and chat with seatmates-- all without removing the headset.  And with the implementation of the Apt-X, you can obtain hi-fi quality sound over that Bluetooth link.

With the MM 450-X you can switch between calls and music -- delivered in superb stereo sound.  NoiseGard 2.0 eliminates up to 90% of background noise for your most peaceful flight yet.  A convenient TalkThrough function lets you carry a conversation with a seatmate at the push of a button.

The invisible high-performance microphone ensures that conversations are clear, making this headset the perfect all-in-one sound solution for the hottest digital device in your pocket.

The MM 450-X folds up for the ultimate in portability.  The replaceable battery charges via USB or a wall adapter.  For situations where Bluetooth is not permitted, you can use the included audio cable for a direct connection- making the MM 450-X at home in any situation where a super quality headphone is required.
