Size: !Only Bluetooth 2.0Color: black Vine Customer Review of Free Product ( What's this? )
The MM 450-X are probably the 10th set of active noise cancelling headphones I have tried. I currently own a pair of the less expensive Creative noise cancelling headphones and they have done well for me during my long flights and weekends cutting the grass. I have owned and returned 2 different versions of the Bose headphones and I have even owned and returned an earlier version of the Sennheiser MM's (the 350 I believe). The 450-X is the first wireless/bluetooth headset that I've tried.

First, the build is very similar to other Sennheisers. They are foldable for easy transport yet are quite beefy so should stand up with some light abuse. I wouldn't beat on these like I do some of my other headphones but they are pretty solid for the style.

I have used these primarily with my Iphone 4S and have used it for both wired and wireless/bluetooth connections. I listen to music on my Iphone every morning on my way to work on the train (mostly through music loaded on my device). It took me a bit to understand how everything turns on when I first opened them. You have to hold the side button down for about 3 seconds to turn on and 4 seconds or so to turn off. If you start in the off position, holding down the button for longer periods will put them into pairing mode which was super easy to pair with my iPhone. No issues at all.

To activate the bluetooth, you simply push and hold the little bluetooth button on the underside and it will automatically pair with your device once the power is turned on. To activate the noise cancelling, you have to hit and hold the other button for a few seconds. If you just hit the button and release, I believe it activates the talk through capability.

Size: !Only Bluetooth 2.0Color: black Vine Customer Review of Free Product ( What's this? )
I have to confess I am not an audiophile but Sennheiser is starting to change that. A year ago I got Sennheiser PXC 310 BT Compact Noise-Canceling Travel Headphones with Bluetooth Technology (Black) and I have fallen in love with them. When I got a chance to get a review pair for MM 450's I jumped. These are ever bit as good as old ones and I can't wait to use them on a flight soon.

--Use: It is very easy to pair these to blue tooth devices. I mostly use these in conjunction with an iPod Touch. In the evening I usually switch from speakers to headphones so as not to annoy the neighbors and the headphones take over immediately when I turn them on. Also I enjoy being able to skip forward and backward in the playlists by tapping the buttons on the ear piece. I still have issues with missed phone calls, but I get absolutely no distractions when working with them on (short of a fire alarm.)

--Sound: The Sennheiser sound is better than any headphones I have ever had. I'm not a big fan of base and at first I felt that they did not get loud enough, but now I appreciate that I cranked my headphones to get over room noise. With the noise canceling this is not an issue.

--Design: I love the folding design. they fold flat and fairly narrow and fit into its well designed carrying case well. The smaller ear muffs are not as hot as the full sized ones which is nice and fit comfortably on the head, although sometimes I feel a little twist due to the folding hinges. But all in all they are well crafted and comfortable.

First off, my review is from the vantage point of my primary use for these headphones -- and that is playing poker. So far I've worn these headphones for about 60 hours.

I will be the first to admit that the noise cancelling, while very good (IMO), is nowhere near as good as the QC15 headphones by Bose. I'm lucky that I have both sets of headphones, and I find myself using the Bose when flying simply because they are better for that purpose.

Once I land at the casino however, the Bose headphones stay in the room and these come out.

-- Size: They're smaller than the QC15s or the MM550s. Spend a few hours wearing them and you'll grow to appreciate the fact that your ears aren't sweating! Being smaller, it's also easier to leave muff off the ear so you can hear everything going on around you. The carrying bag is much smaller than the QC15s or MM550s (duh) and it has everything I need (headphone wire, USB cable to charge and extra battery). It is small enough to go in a cargo pocket.

-- Bluetooth Part 1: My original reason for ordering these was simply because I was fed up dealing with tangled wires. I knew there were plenty of "in ear" Bluetooth designs, but I also knew from experience I wouldn't like them (I can only wear "in ear" headphones for so long before it becomes painful).

-- Bluetooth Part 2: Buttons, baby -- buttons! Not only do I no longer have a cord hanging out of my pocket, but now I don't even have to take my cell phone out to skip or repeat songs! Receiving calls and talking on the phone is a breeze.

-- Battery life: Sennheiser claims eight-hour battery life (if memory serves). When I first ordered these, I ordered a backup battery, because those claims never seem to be true. The claims are true!
