About the Sennheiser MM 450-X
The travel headset you've been waiting for
The travel headset you've been waiting for
Built with the world traveler in mind, Sennheiser's MM 450-X lightweight, portable headphones give you superb stereo sound, wireless convenience, and relief from the din around you. Now you can listen to your music in peace, manage phone calls, or chat with a seatmate, all without ever taking off your headphones.
Sennheiser's active noise-canceling circuitry quiets outside sounds, while Bluetooth technology lets you make hassle-free wireless connections to compatible devices, such as many cell phones, laptop computers, tablets, and MP3 players. Integrated volume, track skip, and call answer/end buttons built into the earcup provide convenient operation while your phone or music player remains safely in your pocket, purse, or backpack. Plus, the MM 450-X headphones support the latest aptX technology a sophisticated audio circuit that delivers true high-fidelity stereo sound wirelessly over Bluetooth with aptX-enabled sources.
Noise-canceling technology gives you peace and quiet
Sennheiser's NoiseGard 2.0 technology reduces extraneous sounds by up to 90%, such as engine roar, wind noise, and the conversation of surrounding passengers. Tiny microphones in the headphones pick up the sounds of your environment. Advanced circuitry then creates a signal that "cancels out" much of this external noise without affecting your music or phone calls. A handy "TalkThrough" function lets you temporarily override the noise-canceling circuit with the push of a button to carry on a conversation with a seatmate or give your drink order to the flight attendant.
Exceptional comfort, sound quality, and convenience
The MM 450-X's soft earcups feature plush leatherette cushions that feel great. An adjustable padded headband ensures comfortable listening for hours on end, making these 'phones ideal for long trips. Plus, they fold up into a compact package to fit inside the included carry pouch for easy transport. Sennheiser's patented Duofol diaphragms deliver detailed, crystal clear sound. And just in case you need it, Sennheiser includes a cable plus an airline adapter for a direct wired connection in situations where Bluetooth is not permitted, or you want to make use of in-seat entertainment and other wired sound sources.

Features
Overview: The Sennheiser MM 450-X headphones are an accessory that allows you to enjoy your digital music files on your mobile phone or portable music device, including those equipped with Bluetooth technology. The MM 450-X can be used wirelessly, or in places where Bluetooth isn't available, you can plug them in and use them as wired headphones.
Bluetooth Wireless Reception/Transmission: The MM 450-X features Bluetooth v2.1 wireless reception and transmission with a built-in microphone for cable-free use with select Bluetooth enabled phones and audio devices. Supported Bluetooth profiles include A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile), HSP (HeadSet Profile), and HFP (Hands-Free Profile). The MM 450-X saves the connection profiles of the last eight devices with which it was paired; when turned on it automatically tries to connect with one of those devices.
apt-X: The MM 450-X headphones are equipped with apt-X, an audio coding technology that works within Bluetooth to wirelessly deliver CD-quality audio from your portable music device to the headphones. With apt-X, you can listen to your digital music files in crisp, pure, and full stereo sound.
NoiseGard 2.0 Noise Cancellation: NoiseGard technology is an active noise compensation system, originally developed for use by pilots. NoiseGard uses tiny microphones to measure ambient noise (up to 1 kHz) near the ears. The phase of the noise is then inverted (180° out of phase) and added to the original noise, reducing background noise by up to 23 dB (90%). NoiseGard can be used with Bluetooth wireless reception or when the MM 450-Xs are wired; NoiseGard can also be turned off when not needed.
TalkThrough: The TalkThrough function allows you to have a conversation with the person next to you without taking the headphones off. When TalkThrough is activated, microphones mounted on the outside of the headphones pick up sound in the immediate vicinity and background noise is filtered out (the music is also turned off).
Controls: On the right ear-cup there are integrated controls for your connected phone or audio device. Audio controls include volume, skip forward or backward, fast forward or rewind within a song, play, and stop. Phone controls include volume, accept call, reject call, end call, redial, voice dial, and mute.
Battery Pack: The MM 450-X has a removable BA 370 PX Lithium-Polymer battery pack (3.7 volts DC/1 Wh) which provides up to eight hours playback using Bluetooth reception and NoiseGard, up to ten hours playback using Bluetooth without NoiseGard, and up to 20 hours using just NoiseGard (with Bluetooth turned off). A power supply with US, UK, European, and Australian plug adapters is included to charge the battery pack; charging time is approximately three hours. The headphones can also be charged using a computer's USB port.
Collapsible Design: These headphones feature a collapsible design with metal-reinforced headband to ensure portability and durability.
Cord & Adapter: The MM 450-X will also work as wired headphones, useful when Bluetooth connection is not an option. The headphones come with a 56" mini-jack cable terminated by a 3.5mm connector for a wired connection. A 3.5mm to full size 1/4" adapter and an in-flight audio adapter (dual mono 3.5mm) are included for added convenience.
Carrying Case: A nylon carrying case is included to protect the headphones during storage or transport.
