Sennheiser MM 450-X Travel

by: Sennheiser

With one Sennheiser MM450 X Bluetooth headset headphone, you can listen to music wired or wirelessly, take phone calls over Bluetooth, cancel 90% of ambient noises around you and chat freely with seatmates, all without removing the cans from your head. Employing the superior Apt-X codec Bluetooth transmission scheme, listeners can get true high-fidelity sound quality direct from a tablet, computer or smartphone without any encumbering wires in between. The MM450-X allows easy switching between calls and music, all delivered in superb stereo sound with Sennheiser's NoiseGard 2.0 technology working hard to eliminate environmental background noise for your most peaceful travels yet. Convenient 'TalkThrough' button lets you carry a conversation at the flick of a switch.

What We Think:
The Sennheiser MM450-X is very similar to the MM400-X model but adds proprietary NoiseGard 2.0 'active' (battery powered) noise-cancellation plus a handy 'Talk-Through' button for easier conversation without necessitating removing the headphones every time the steward walks by. The headphones can be used in either standard wired or wireless Bluetooth modes as desired by the listener and a 5ft audio cable comes provided. You can also choose to activate or turn off the noise-cancelling features at the flick of a switch. We hear the sound as pretty respectable in either setting, unlike some NC headphones whose sound quality plummets when the batteries are shut down. The overall tone is excellent for this category of headphone and presents a highly intelligible sound good for speech and film dialogue when watching movies on your laptop or tablet computer. For music listening applications, there's frankly not much better in the wireless headphone world without getting into something like the home/office-oriented [non-portable] SONY MDR-DS6500 or the Sennheiser RS220 wireless audiophile headphone systems.The Sennheiser MM 450-X hinged headband is superbly well-built and folds / collapses for the ultimate in easy travel portability. The MM450-X contains a replaceable lithium-ion battery able to charge either via USB or via an included AC wall adapter providing about 10hrs of listening time per charge. For situations where wireless Bluetooth audio transmission is not permitted (airline flights), you can use the included audio cable for a direct connection to your source making the MM 450-X effective in any situation where a super high-quality portable headphone is demanded on your travels.
