The MM 550-X Around-Ear Stereo Bluetooth Wireless Headset from Sennheiser is a high-quality wireless headset that allows you to enjoy your music with virtually any Bluetooth-enabled device, as well as make phone calls with Bluetooth-enabled multimedia smartphones. The headset is compatible with iPhones, iPods, iPads, Android devices, and more. It also supports the Apt-X codec, which provides enhanced audio quality when the MM 550-X is used in conjunction with an Apt-X-enabled device.

The headset features Sennheiser's active NoiseGard 2.0 noise-cancellation technology, which improves audio quality and reduces environmental noise by up to 90% so you can focus on your music instead of your surroundings. It also has a TalkThrough function that lets you hear your surroundings without having to take off the headphones, ideal for listening to announcements or having a brief conversation. Switchable SRS WOW HD simulated surround sound is also built into the headphones for added depth and realism.

The headset has a collapsible design for terrific portability. The around-ear design and soft ear cushions provide excellent comfort and noise isolation. The patented DuoFol diaphragms and neodymium magnets deliver detailed, natural sound with terrific bass. The integrated microphone is invisible and out of the way, but provides excellent vocal pickup. Controls for volume control, track skip, play/pause, and answer/end call are conveniently built right into the headset, giving you full control without having to remove the headset.

In situations where wireless listening isn't ideal, a detachable cable is included that turns the headset into a pair of wired headphones. The cable has a standard 3.5mm plug for compatibility with MP3 players, CD players, laptops, and more. A dual-prong airplane adapter is included for use with in-flight entertainment systems, while a 1/4" adapter offers compatibility with pro-level gear and home theater systems. The headset has a replaceable battery that charges via a USB connection, and a multi-country wall adapter is included so you can recharge practically anywhere. A carrying pouch is included for convenient storage and portability.

Note! Due to the nature of Bluetooth technology, users may experience a slight audio latency when watching video on a portable device. This is a characteristic of all Bluetooth headsets. Latency is not an issue for audio-only use, or when using the included detachable headphone cable for a wired audio connection when watching video.

      Comments about Sennheiser MM 550-X Around-Ear Stereo Bluetooth Wireless Headset:

      I use this for phone conferences and listening to music. The sound quality matches my bose unit (bluetooth and with the cord). Generally I leave noise cancellation off, except when flying. And then it is quite effective. Reviews on another site repeatedly mention low volume, even at maximum levels. It is not clear why this is perceived as an issue since max volumes are never needed.The only negative, and it is not really a negative, is you do need to read the manual to use these effectively.

        Comments about Sennheiser MM 550-X Around-Ear Stereo Bluetooth Wireless Headset:

        These are 'Made in China' NOT in Germany. For headphones in this price range, you'd think they could manufacture in a developed country. That being said, they feel solid for Chinese manufactured goods. Also, what's up with the really cheap soft case for such expensive earphones? Even the Bose QC15 comes with a solid case, but these have a smaller footprint in your bag, and the Bose wire is so flimsy.

        I own several other pairs of headphones, which include: Bose QC15 (wired overear), Jaybird (BT earbuds), Shure SE535 (wired earbuds), and Beats (wired earbuds).

        SOUND QUALITY: no comparison to Shure SE535 from bass to all the way through soprano (I used Le Nozze Di Figaro using fairly low compression)(at the high-end, they are respectable but it lacks the crispness and support for the notes that is present in the Shure SE535, and the low-end sounds more mushy than the Shure SE535). I know, not a fair comparison b/c wired to BT. That being said, I can hear very immaterial differences at both ends of the spectrum, when put up against the Bose QC15 and those too are wired. Against the Jaybirds (both BT wireless using iPhone 5s), assuming one can get a perfect plug with the Jaybirds, these best those. Whereas the Jaybirds rely on a higher volume, you can tease out more detail in the music. I can hear individual instruments in the orchestra but not in way where any single instrument sounds out of place, or annoying, or clustered. Forget the Beats. Those are expensive iPhone 5s earbuds with absolutely disasterous bass and sound, in general. Only other thing to note about sound quality, yes these are NOT as loud as the others ... like a volume limit, but it's not necessarily bad because IMHO it's loud enough without blowing out your eardrums. With my Shure SE535 I forget the volume I left my iPhone and plug them in and WHOA!!! It hurts my head. Here, I don't have the option of blowing an ear tube. :)

        BLUETOOTH: Awesome!!! Works with every device I own: iPhone 5s, Galaxy S4, MacBook Pro, iMac, and even my cheap work computer. I've not lost connection and their pair up very easily.

        NOISE CANCELLATION: I agree they are not as good as the Bose QC15, but they sound better without the N/C. Also, 110% agreed that the N/C really diminishes the sound quality, which was of pinnacle importance to me. Here's the rub though. I found that w/o the N/C, it still did well to seal out enough noise on the NYC Subway, and no sound leakage that I can tell, so go ahead and blast Backstreet Boys. :)

        BATTERY: I routinely get 10+ hours, but I still bought a couple spares to keep in the pocket of the carrying case, just in case. Enough said.

        TALK QUALITY: I've taken some business calls with these headphones and nobody even knew I was using headphones, which means either these are good, or the people I speak to are all half deaf.

        COMFORT: I wear these 10+ hrs. a day at work in my office, to listen to music and help me concentrate. I feel NO ear fatigue at the end of the day -- something I couldn't do with those jam in your ear buds. The cups are a bit small, but sufficient to cover my ears. If you have larger ears, you'll probably appreciate the QC15's larger ear cups, but those are not wireless. Added benefit: it's been COLD in NYC and these actually keep my ears nice and toasty when I am commuting to/from work and client's offices. :)

        OVERALL: Great earphones from reputable brand, even if 'Made in China.' 2-yr. warranty is nice too. I considered the Parrot Zik too, but considering my #1 priority for earphones is SOUND QUALITY, I think I made the right choice. BT headphones have come a long way, and I'm sure more improvements to come.

        * This product is essentially used for home-use: listening to Pandora or TuneIn Radio from either my LG Phone, or Blackberry, or iPad.

        **** Great:
        1. The quality is above average for sure. The controls are smooth and easy to operate - as long as you read the instructions.

        2. The Bluetooth connection (recognizing and connecting to devices) is pretty smooth and straightforward.

        3. The additional electric adapters and connectors (AC Plug, replaceable battery, airplane and stereo hook-ups) and battery length (7-8 hours) are all wonderful!

        4. The connection to iPAD is simply amazing. I can go and listen to it wirelessly (via Bluetooth) from almost anywhere in the house

        5. BH Photovideo store delivered the product quickly and in an outstanding fashion! Thank you!

        * Not so Great:

        Only one: my Bluetooth connection to my Smartphone LG Optimus is not ideal if I'm not carrying the phone in my pocket.

          Comments about Sennheiser MM 550-X Around-Ear Stereo Bluetooth Wireless Headset:

          I bought a pair of the Sennheiser MM 550-X Bluetooth Headphones about two months ago and waited to write this review to experience the good and bad features of these headphones. Because of the cost, I did a bit of research before I made my decision. In my research, I found reviews, some good and some not so good. Some reviews indicated that the sound quality and noise canceling qualities were not as good as it should be. Trying to maintain an open mind, I questioned some of these reviews because some of the individuals that consider themselves as an "Audiophile" seemed a little prejudice. Their reviews basically indicated that the sound quality of the MM 550-X headset was not as good as other headphones such as, the wired Dr. Dre's and other like headphones; additionally, the noise canceling qualities were not as good as the Bose QC-15s. After reading these reviews, I found no evidence that an analysis was conducted with calibrated audiometric equipment to substantiate their technical opinion and that most of these reviewers either did not have or indicated that they were holders of credentials to support their remarks other than their opinion.

          So for what it is worth, here is my opinion. After opening the box, I found that the headphones to be well made, small, and comfortable to wear. The noise canceling features of the headphones are fantastic, one of my office mates has a pair of the Bose QC-15s and I would say that they are about equal in noise cancelling qualities and from my prospective I did not hear a dynamic audio difference that would cause me to buy the Bose over the Sennheiser. I found that the sound quality, for purposes which I use the headphones, the size of the headset, and the wireless Bluetooth; the sound quality is fantastic. I am sure that there are headphones out there that have better sound quality than both of the Bose or the Sennheiser. However, before you decide to buy based on noise canceling qualities of a headset, I recommend that you visit You Tube, "Product Tour: Sennheiser MM 550-X Around-Ear Foldable Bluetooth Stereo Travel Headset", I guarantee that you will be surprised.

          Comments about Sennheiser MM 550-X Around-Ear Stereo Bluetooth Wireless Headset:

          NoiseGard: it cancels most of the noise on the bus, haven't try them on a plane yet.
          SRS thing: don't like it on. I think the music sounds better without it.
          Bluetooth: really good. when you turn the head phones on, they auto pair with the last bluetooth device they connected. I can leave my iPod in my backpack and just forget about it. Every control that I need if on the headphone.
          Build: very durable and nice looking/feel. also very portable.
          Battery: with bluetooth and noisegard on, it can last about 9hrs (3hrs a day for 3 days)

          Note:
          The volume control on the head phone is for the headphones only, not for the music player.
          With the wired configuration, it has a lot of noises when the headphone is on. However, if you turn your headphone off the noise goes away...
