Product Description

Style: MM 450 Flight

From the Manufacturer

An ideal headphones for frequent fliers who want to be enveloped in their music rather than the drone of outside noise, the Bluetooth-enabled Sennheiser MM 450 noise cancelling headphones provide a detailed sound image, while patented NoiseGard-2.0 technology minimizes background noise in trains or planes.

It also keeps you in touch by mobile phone wherever you are--answer calls wirelessly by simply by pressing a button on the ear cup. The easy-to-use controls are within optimum reach and provide concise "click" feedback, and the invisible high-performance microphone ensures that conversations are clear--making this headset the perfect all-in-one sound solution. It also includes a direct cable option, enabling you to listen as a wired headphone when Bluetooth is not permitted (mobile phone conversations require Bluetooth).

These closed mini headphones are embedded with NoiseGard 2.0 technology, which provides up to 90 percent active noise cancellation. They are also equipped with TalkThrough function, which is able to distinguish between background noise and speech, enabling you to continue your conversations with fellow travelers without removing the headphones.

When not in use, the MM 450 can simply be folded away and stowed in the included carrying case.

Sennheiser's NoiseGard Technology

Sennheiser's NoiseGard 2.0 technology guarantees undisturbed music enjoyment and ensures that you have a relaxed journey. Irritating background noise is minimized by anti-noise, a technology that was initially developed for pilots and which has already been used successfully in the cockpits of major airlines for several decades.

And if you want to talk to the person sitting next to you, that's no problem either. The convenient TalkThrough function enables you to conduct a conversation without removing the headphones. At the push of a button, miniature microphones mounted on the outside of the headphones pick up the surrounding sounds while an electronic circuit filters out the voice of the person speaking to you and plays it clearly through the headphones.

The sound is great.

I would not buy this particular set again and probably will not buy Sennheiser brand again depending on how the warranty and replacement set works out.

Style Name: MM 450
Updated, October 2010:

I stand by many of the comments in my original review. First impressions were mostly accurate.

I sleep with these headphones a lot, and they get a fair amount of abuse. So far, they don't show a sign of wear - well, not outwardly. And they have also loosened up a bit, and are not as tight as they were to start with, though I doubt these could ever be as comfortable as a headphone which enveloped your ear entirely. Maybe that's the price of portability.

These cans are well built, and aside from the slightly awkward and less than ergonomic volume and shuttle controls, evoke warm fuzzies for many aspects of their design and engineering.

But one observation has me moving this product into the "Do not buy" category, and that is the battery life. It's atrocious. The battery is so small, and so poor at holding a charge that I find them frustrating to maintain. I have enough devices nagging for a charge as it is, I sometimes feel as though I am running a daycare center for gadgets - or a nursing home. That these can't even outlast a fully charged iPhone say a lot. And it's easy to see why - the battery is *TINY*.

I guess the good news is that the battery is user swappable, and can be charged outside of the headphones. So if you can get hold of an extra one, you could always just pop in an extra one that is charged. The bad news is I still haven't seen them for sale anywhere, though to be fair I haven't looked in a while.

Still - it's a shame and a fatal flaw of this model at least. I think they could have doubled the size of the battery without bulking things up.

Difficult item to review completely as I've only had them a short time.

I am not sure where to start!

I own several Sennheiser products including the HD 580, HD 590, HD 600, HD 650, and PXC-450s.

Since I am using my smartphone (Nokia N900) more & more and it works well with bluetooth, I decided to try and replace my TWO year old Plantronics 590A.

The main reason for the purchase of the MM 450s was the "noise-canceling".

Well, after several days of use including in work areas with a lot of "voices" in the background, I have given up on the MM 450s. They sound great but the noise canceling doesn't work very well. I can hear other people's conversations quite clearly when I am in a phone conversation with noise-canceling on (I thought I had it off)!

The MM 450s have also disconnected from my Nokia N900 and Nokia N97 quite often (I have never had this problem with my Plantronics 590s which I currently use all day (+10 hours)).

IF the MM 450s were ~$250, I would keep them because of the great sound... but for $450, I want great sound + noise canceling.

So my set of MM 450s are going back to Amazon!

UPDATE 01/16/2010:

I replaced the MM 450's with my 2nd choice, the Nokia BH-905s! After several days of using them, I think they are almost as good as the MM 450's and the price was only $209.00 delivers (much better than the $450.00 for the MM 450s).

Comparison between both:

Sennheiser MM 450:
------------------
+ Fold up smaller for travel.
+ Sound is best I have heard for bluetooth.
- Price
+ Battery is user replaceable
- Case is CHEAP
- Battery life with noise canceling on was about 10 hours.

Nokia BH-905:
-------------
+ Price is around $200 if you shop around.

While these are pricey, the sound is by far the best that I've ever heard from a bluetooth headphone.

I'm not an audiophile, but I do like good sounding cans. I've got a set of ER 4Ps, SE 530s, Denon AH D5000s, Nokia BH 905, and now these. The sound is certainly not as rich as the SE530s or as Spacious and complex as the Denons, but the lack of wires... I mean, it's like when I got my first iphone after years of running on treos: a breath of fresh air. But I digress (will come back to the wireless though). The sounds are head and shoulders above the Nokias. I actually bought the nokias first, after buying (and then returning) the PXC310s (which are the non microphone enabled version of the MM450s). i immediately fell in love with the 310s' sounds, but couldn't get over the lack of a microphone (using on my iphone). The sound difference (vs. the Nokias) was like the difference between the iphone and the treo 680 screens--not only resolution and color depth... but.. it's when a difference in amount becomes a difference in kind. Where the nokias didn't sound like bluetooth headphones, the sennheisers sounded like good headphones, period. I could still pick out the glass clicking and people whispering in the background on Ella and Louis' rendition of "Baby it's cold outside"--my defacto test for headphone qualitiy-- I was first (pleasantly) startled by these background sounds when listening to the recording on my er4ps years ago and have since used the recording to audition. The base is tight and punchy; the treble is clear and floaty, and when you turn on the noise canceling the sound is amplified and given even more depth.

Now back to the wireless. Once I went wireless, I find it hard to go back. These have replaced by SE530s.
