Product Description

With the MM 550 you can switch between calls and music -- delivered in superb stereo sound as only Sennheiser knows how-- without wires! Luxurious, around-the-ear cups powered by NoiseGard 2.0 eliminates up to 90% of background noise for an incredibly relaxing flight. A convenient TalkThrough function lets you carry a conversation with a seatmate (or teammate) at the push of a button. Selectable SRS surround simulation adds excitement and depth to your audio on-demand.

The invisible microphone ensures that you have the added convenience of taking a call without wires, or hassles-- without changing headsets. Using a closed, around-the-ear design to block ambient noise, the MM 550 is an ideal companion for the frequent flier or baller. Advanced DuoFol transducers provide the kind of detail and frequency response you would expect from Sennheiser. The easy-to-use control panel is intuitive and simple enough to operate with your eyes closed-- a common way of enjoying Sennheiser's world-famous sound quality.

The MM 550 folds up to fit in any carry-on. 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 550 at home in any situation where a super quality headphone is required.

Sound quality is good when "wired."
The ear cups are not suited well for adult sized ears and were too tight.
Overall I'm very satisfied with my new headphones and I recommend them.

I've been using the MM550 for about 6 months now, including several international trips and it's performed superbly.

If you want a headphone that truly does everything, this is really it. Bluetooth works for video on the iPad/notebook/ then switch to the iPhone for seamless switching between music and phone calls. The detachable cable automatically switches off the Bluetooth, so it's easy on airlines. It comes with a world-battery chargers and also charges through USB. The TalkThrough function allows you to switch between the headphones an hearing whats going on around you (though I still find myself instinctively taking them off when someone wants to talk to me). The comfort is the best I've had, even better than the Bose QC3, which is very comfortable.

-- Noise Cancellation: As good as, if not better than my Bose QC3's, which was better than any headphones I ever had. What's nice about the Sennheiser's is that you can switch of the NC, which gives even better sound quality (if you're not in a noisy environment).

-- Sound Quality: Excellent! It reproduces everything very accurately. Crisp Treble with great Bass. I listen to everything from, rock, rap, blues, to classical, so I want a headphone that correctly interprets the output from the player, as this is how it was intended by the musician. I didn't want a headphone, as some do, that interpret the sound to one genre, such as excessive bass. These definitely fit the bill.

As with all NC headphones, the sound is best without NC. What's nice about these is that you have the option of switching off the NC.

-- Problems with not enough volume: Some user reviews complained that the volume was too low. This is obviously a big worry, so I was ready to quickly return them.

As background, I bought these headphones to replace a six-year-old pair of Bose QuietComfort 2 Acoustic Noise Canceling Headphones whose faux leather bits have literally disintegrated and also own a pair of Sennheiser HD-280 PRO Headphones.

I always loved the sound of the QC2s, particularly their great bass and fantastic noise-canceling ability. I've seen many reviews putting down their sound quality, but, as I'm an audio layman, they're the standard to which I compare other headphones. They're also the most comfortable cans I've worn, an area where the HD-280s fall far short. While the 280s sound good, I get a headache from wearing them for extended periods because the padding around the cans is not very soft and the headphones press very firmly against my head.

When I went looking for new headphones, I wanted something that sounded and felt as good as the QC2s. One thing I found annoying when travelling with them, though, is dealing with the cable. I found only a few headphones similar to the QC2s in terms of features that also supported bluetooth audio, and decided to give the Sennheisers a shot based on the company's reputation and my experience with the sound quality of the HD-280s. Choosing between this particular model and the older MX-450 was simple: I wanted to see what the latest tech would offer.

These are hands-down the best-sounding headphones I can remember -- if you leave noise-cancellation and SRS off.

These headphones are great. They pair easily, are very comfortable and sound fantastic. I have not noticed any delay when watching videos, as sometimes can occur when using a bluetooth headset. I tried the MM 400s, but found the on-ear style to be uncomfortable. The talk-through feature is great and the buttons are easy to use. These are really well thought-out headphones.

Many people complain about the price, and I suppose it is high compared to some other products. However, everything in life involves compromise. Features cost money, and quality costs money. Cheaper headphones are, well, cheaper. I was nervous about spending this much money on a pair of headphones but after using them for five minutes, I had no doubt that I would keep them.

Two final points: the sound quality really is outstanding. I've heard things in certain songs I never noticed before. The highs are crisp, the mid-range full and the bass robust. Maybe you can get better sound quality elsewhere, but it's hard to see how, unless you want to spend $1,000 or more for a professional, wired headset.

Related to the sound quality, it seems that some computers (like my imac) use different bluetooth protocols, depending on how you connect the headphones. Thus, when I connected in one manner, the sound was great, but when I connected in a different manner the sound was poor. I don't understand it, but that's my observation. Reviewers who are very critical of the sound quality might be experiencing this problem. Otherwise, I don't get it. These headphones might not be everyone's cup of tea, but there's no denying their high quality.
