Sennheiser MB Pro 2 UC ML (506046) - Dual-Sided, Dual-Connectivity, Wireless Bluetooth Headset | For Desk/Mobile Phone & Softphone/PC Connection| w/ HD Sound & Major UC Platform Compatibility, Black

I purchased two competing Bluetooth headsets for my business, and this Sennheiser was one of them. I needed a primary unit, and a backup unit just in case (my consulting business demands very long telephone calls throughout the day). I chose Sennheiser being a long-time user of their products (forty years!) and a fan of their build and sound quality. The build quality of the MB Pro2 is excellent, just as you would expect from Sennheiser. Solidly constructed, yet light and easily worn, the MB Pro2 feels good on the head and comfortable on the ears. The headset just seems to fit naturally, a testament to Sennheisers design team. I REALLY appreciate the integrated charging stand, easily the best feature overall of this headset (keep reading). Pairing the MB Pro2 to both my Macs (running Yosemite) and my iPhone (iOS 8.1) was easy, and I was up and running in just a few minutes. In order to test the headset, I performed a Skype test call (you record for 10 seconds and Skype plays back your recording). I immediately noticed that the sound quality was good, but a little grainy (as is usual with Bluetooth headsets). Whether this is a result of the Bluetooth codec, the mic, or the earphones, I'm uncertain. But, strangely, the boom mic just didn't pick up my voice to the extent that I was expecting -- it sounded dim and slightly distant, even though the mic is literally 2 cm from my mouth. I adjusted the headset volume to its highest level, but no joy -- still the same dim and distant presence. I was able to compensate by talking a little louder, but my voice level is noticeably unnatural at that volume and it seems like I'm being verbally assertive. After about a half-hour of testing, including disconnecting and reconnecting via Bluetooth (to see how robust the connection capability is), I felt that I understood the headset and was ready to use it. To contrast, my other headset is a BlueParrott B350-XT in a very similar configuration, but with only one earpiece (and, sadly, no integrated charging stand). The BlueParrott is solidly constructed and feels good on the head, but -- in my limited subjective testing -- has better sound quality, and at a better recorded volume than the Sennheiser. I wasn't expecting this at all. I don't have to elevate my voice with the BlueParrott, and the sounds is slightly less grainy (more "fluid"?) than the Sennheiser. So, the bottom line is this: the Sennheiser MB Pro2 XL is a very good headset, with good quality sound and excellent design features (especially the integrated charging stand) and the welcome stereo ear cans; it is a core part of my daily work life and workflow. However, if I had to do it all over again, I'd probably elect to simply get a second BlueParrott B350-XL as a backup headset as the sound quality is subjectively better, even though it doesn't come with the nifty integrated charging stand and has only one earpiece. *** One-week Update *** Long story made short, I discovered that my headset was operating on a very old release of firmware (1.0.x). I was able to determine how to update the firmware from the Sennheiser site, and was able to get the firmware up to the current 1.1.x level. Both the questionable quality audio (slight raspiness) and the poor voice pickup on the mic are now history and calls are very clean in both directions. Now, the only complaint I have is that one of the headset ear cups rests on the base of the stand when the headset is mounted on its charging station. This may actually be an intentional design feature that stabilizes the headphones while being charged. My only concern is that the matte surface on the headphones may wear down over time by regularly scuffing the base of the stand. Not a big deal, but something to note. This is now my primary headset and it now works flawlessly. I've relegated the BlueParrott to my computer bag for travel. I'm raising my rating to a full five stars. I'm absolutely thrilled with this purchase. Note that the Sennheiser updater is a Windows-based program, so you'll need access to a Windows machine (such as a family member's or friend's system) or operating system instance (such as a Windows 7 virtual machine running on your Mac) in order to perform the update. Once the update procedure is complete, you'll be able to continue using your headset on your Mac, iPhone, etc. The updater is NOT required in order to use the headset on a Mac, iPhone, etc. *** Five-month Update *** This headset is absolutely rock-solid and performs flawlessly. I use this thing for 5-8 hours per day on a daily basis, and, frankly, couldn't imagine working without it. Absolutely no complaints at this point. It's comfortable and wears well. It is well designed and everything is "in its place". The boom is the perfect length and stays just out of the way. The headset has just the correct weight (not too heavy, not too light), and it has that intangible "feeling of quality". It behaves well via Bluetooth signaling (i.e. informs my iPhone that it has been picked up off the stand which then answers the call, etc.) Sound quality remains superb, and people tell me that my voice is crystal clear on the other end. The charging stand is a God-send and keeps the headset constantly charged without me having to think about it. This has been a fantastic purchase and one that I would do again in a heartbeat. I wish all products were as well developed and integrated as these 'phones. Reiterate: 5-stars. (P.S. And, no, I have no affiliation with Sennheiser whatsoever, other than the many decades that I've been a customer of theirs).

--My context-- I'm not on the phone for a living, but I take 5 or 8 calls per day on this device. With a normal call being 5 or 8 minutes and a long call being 30 minutes to an hour. I work in standard office building that has a closed floor plan (offices with real walls, not cubes). --This headset is almost perfect-- -Battery life is as advertised, and it charges lighting fast when it does run out. -it's very comfortable, light & adjustable - parts and construction seem very sturdy - everyone can hear me clearly (mic is great) - the button for answering or ending calls is easy and intuitive to find without looking - the rocker switch for volume has too many functions and motions (it depresses awkwardly for muteing the mic), this overloading causes it to be a little clumsy/small to address. I'd much prefer to see a wheel for finer and faster tuning the volume, and a separate switch or button for mic muting (ideally put that on the mic itself) - the Bluetooth itself is pretty reliable. it seems to pick up my Bluetooth iPhone and connect 96% of the time (not bad, but not perfect). But when it doesn't pick up my iPhone Bluetooth, usually a single press of the call answer button picks it up right away. For me this reasonably fixes that 4% issue of not connecting. And to be fair, it's not clear if this issue is the phone or the headset. -The computer dongle connects on Bluetooth a bit more reliably than my phone. Can't recall ever having a connectivity issue there. -The software in the phone is awesome. It does a fantastic job of seamlessly working simultaneously with the computer dongle and the phone. There is nothing you need to do but answer calls or make calls and it just works - it's fast and seemless. Also, surprisingly there is a useful and pleasant voice that tells you things like "recharge headset" or "iPhone connected", etc. It turns out that voice is crutial and useful because there is no other way you'd know such things (no visual user interface). The voice software telling you status does a fantastic job, tells you the right things at the right time without being annoying. - the one thing that sucks, and the only reason I gave this 4 stars is ... the maximum earphone volume and isolation isn't good enough for crowded environments. The max volume on this device is about every other headsets medium volume. This is usually fine for me, but if I walk to a cafe to work, it is hard to hear the call... and to make it worse, it's easy to hear the ambient noise of the room (related but different issues). This is the number one thing Senheiser needs to fix. Give me better isolation in the headphone from ambient noise, and give me a volume notch for "eleven". I'll buy this again, right away, if they fix that issue. The last thing that doesn't suck, but it is only maybe 3 stars is range... I'd say the range is well less than advertised. After about 50 feet of distance there is a very noticeable and exponential decay in call quality. It's really only usable within less than 40 ft in my opinion. This isn't a deal breaker for me at all though. overall this is definitely still a must have if you like taking calls hands free in an office, and want that to work seemlessly for both phone and computer on one headset device.

By far the best business-oriented wireless headset I have ever used (and I did use quite a few, wireless and wired ones). Here is a quick overview (after ~6 months of everyday business usage). PROS - Lightweight. Can stay on for a few hours w/o any discomfort - Great battery life. I use it every day (~1hr, sometimes more) and still only need to recharge once a week. - Great sound quality (both ways, mic and headset). - Room Presence is wonderful (I turned it on and after getting used to it, left on permanently). I really like it as it does make conversations more natural sounding. - Ability to connect both phone and computer at the same time is very convenient (as some meetings would not support computer-based audio so one has to dial-in) - Exceptional with iPhone 6 - Great Mac OS X compatibility (up to El Capitan 10.11.x; latest at the moment). - Great Microsoft Lync for Mac compatibility (to the point it even muted the mic when you join a Lync meeting or presenter has elected to mute all participants). Also works great with AT&T Connect (Mac) for those who use it. - Supplied USB dongle enables high quality of sound (voice) and is recognized by Mac OS X w/o any drivers CONS - Originally, I thought the price was high (I could not have imagined spending that much on a headset). Now, after 6 months I think it is very reasonable considering the overall features/performance. - Music quality sucks. Don't consider that you can use this headset for music; it is not designed for that. It's low frequency response is cut ~150Hz so lows do not exist here. Imagine Senheiser headphones with dark sound signature (subtle highs) but w/o lows? No, not for me. - (not really cons, just a note) One must use supplied USB dongle. While headset supports standard bluetooth profiles, if connected directly to Mac (no dongle), voice quality through Lync is terrible (occasional dropouts/cannot understand anything). This never happens through the supplied USB dongle. Overall, very happy with it and would definitely highly recommend it for business usage.

I'm a software engineer. Like a good mechanic years ago could tell you what was about to go wrong with your car just by listening to it, or like Rolls Royce can tell with sound and vibration sensors when an aircraft engine is going to fail, or like Uptake can predict when train locomotives are going to fail; I can usually tell when there are software bugs causing a problem. These have software issues with the digital signal processing, Bluetooth, or firmware. The bugs are intermittent, inconsistent, and no doubt difficult to reproduce, but the result is that people randomly can't hear you, you can't hear them or sound quality in either direction is poor. Also, the microphone noise canceling implementation is inconsistent. Mostly you drop out and people can't hear you. Interference you say? Nope, happens in the corn fields too, but even so, Bluetooth operating on the same 2.4Ghz spectrum as WiFi, and USB 3.0 operating at 2.4Ghz is a reality; it can and must be mitigated with software. How do I know? Because my Samsung Bluetooth ear buds don't have these problems. Bummer, I wanted this headset for years and finally purchased a pair. They feel great! Extremely nice physical quality and comfort. And nothing should be able to compete with a boom mike for noise canceling and speech clarity! ...but sadly Sennheiser, or Epos, or whatever they call themselves these days mismanages or mis-hires their firmware developers. I don't want to throw them in the trash, but I can't have clutter lying around in my house nor be dropping out in meetings at random moments. :(

I tried several head phones before landing on the Sennheiser. I wanted a device that was comfortable, with longer lasting batteries and especially one that would pair with both my laptop and cell. This one does the trick perfectly. It has great sound and noise cancellation. Others have commented on the high quality of my sound on Zoom. And it switches without any action on my part to in coming cell call if I simply tap answer on the phone. After the cell call it links back to the laptop (and if active) the Zoom call. It is easy to lock onto the charging stand and turns off when so mounted. One draw back, it does require the unique Sennheiser charging stand as there is no separate USB plug connection. An inconvenience as I travel and this requires me to unplug the stand and carry it along. But the stand does hold the headset in an upright position and it is very easy and quick to take the phones from the stand and put on with minimal effort.

I had a EPOS Sennheiser wired headset and was happy with it so I decided to get a wireless one. Most importantly it sounds good, the mic works well, the battery lasts all day and it is light and comfortable just like the wired headset. Their are some issues which I haven't figured out a solution for though. 1) I can't upgrade the firmware. I downloaded EPOS connect and it showed two devices. The BTD-800 dongle and the MB PRO 2 headset. And they both needed firmware updates. The dongle updated without problems, but I still can't get the headset to update. It gives me a message to plug the headset in directly and hit continue. So I popped off the earpiece and plugged in a micro-usb to USB-A cable, then plugged it into my computer, clicked ok, then waited. After about 30 sec it says update failed. If I try to refresh the update page with the USB cable already plugged in, it doesn't recognize the headset at all, it just shows the dongle. I tried this with my Mac as well with the exact same results. I've also tried using different cables and every USB port on my PC and Mac. I just can't update the firmware on this. 2) The only way to adjust the volume is with the physical button on the headset. The windows volume controls do nothing even though it says that the current device is EPOS BTD 800. I've spent hours trying to figure out how to fix the above issues with no luck. For a $150+ product you would expect the software and firmware to be useable. This just shows massive lack of quality control in my opinion. And like I said this is both PC and Mac software, neither version works. I returned the first headset I received thinking that maybe I just received a broken device, but the second one has the exact same issues. I think I'll keep it, but I doubt I'd ever buy an EPOS product again.

I have had this headset for two months. I bought this for using at work so that I could switch somewhat seamlessly between computer, cell phone, and MP3 player. The headset will remember eight devices. But, it only stays connected to two at a time. In order to connect to a third device, you have two disconnect the Bluetooth connection for one of your connected devices. My typical use is to connect with my cellphone and the dongle on my Windows PC. I listen to Pandora and when a call comes in by Skype or cellphone, I can immediately answer the call by pressing the button on the outside of the earpiece where the microphone boom connects. When the call is over, press the button again or click the phone icon in Skype to hang up and the music from pandora resumes. The same operation works with my MP3 player. Volume is controlled by the phone or by the volume rocker switch in the headset (below the earpiece where the microphone boom is connected). People tell me that I come through loud and clear when speaking. So, the microphone is very good. The microphone boom has at least 270 degrees of rotation. So you can place the boom on either side of your head. The headset has standard Bluetooth range of 10 meters (33 feet) that is relatively unobstructed. Reception range will decrease going through walls. This headset does not get really loud. It is plenty loud for listening to music and speaking on the phone. But, you shouldn't expect that it will drown out other nearby loudness. The ear pieces muffle office ambient noise, like coworker conversations, but don't expect to shut out really loud noises (it will not keep out the noise of a lawnmower that you might be pushing). Also, don't expect to turn up your rock and roll tunes to ear popping levels. I listen to jazz, easy listening, new age, classical, pop, and western music. The headset has been fine for that. I don't expect serious audiophile listening in this use and this environment. But, the music sound very good. The headset is relatively light to wear. It has about four or five positions for head size. I wear a large size hat. When I walk, taking a short break, I put in my cap and adjust the headset so it's larger to go over the cap. I then connect the MP3 player and disconnect the computer. I cannot adjust the volume on the headset using the MP3 player. It's probably an issue with the Bluetooth protocol on implemented with the player. I am using a high definition Sony Walkman. But, the volume control on the earpiece works ok. I wish the volume on the headset would go a bit higher because when I walk down the busy street, I can hear the traffic noise. The overall build is good. But, I would not want to treat this roughly. I can see that it would break easily if you tossed it in your bag. The same thing can be said for the recharging stand. I couldn't find a carrying case for taking this while traveling, so I found a generic leather case. After traveling with it, I decided it would be a bit fragile and bulky to take on quick one or two day business trips. I really like the headset. It is advertised at 15 hours talk time. I can listen and talk all day on the headset without running out of battery power. It is supposed to recharge in 2 and one half hours with your computer. That doesn't seem to work for me. So, I plug the stand and let it charge overnight. I would definitely recommend this for someone working in an office. I love to walk around when I am on conference calls, and the headset works very well for that.

I bought the Sennheiser MB Pro 2 UC ML because I am on the phone a lot these days and being tied to my computer with a corded headset was less than ideal. I've used Sennheiser headsets for years and I am a fan. The sound quality is always good and people I talk to tell me the quality from my end of the call is excellent. But the cord..... And so I decided to go with the cordless headset. I use the USB dongle in my computer for connection and it works great. I can also use bluetooth to connect to my iPhone and that is also great for calls. The one thing this headset is not is ideal for music - the tones do not come through like they do on a pair of headphones intended for listening to music or high end audio. But that's not what I bought this for - I bought it to wear all day while talking on the phone, and for that (it's intended purpose) it's outstanding. The headset is comfortable to wear all day and the noise cancellation allows me to talk while doing other things without the person I'm talking to hearing lots of distracting background noise from my end of the call. The battery on this thing is amazing. I have used it all day, forgotten to turn it off at the end of the day and left it off the charger, then returned the next day and used it again all day without ever needing to charge it. It is pricey, but if you are on the phone like I am, and you are tired of poor fitting and poor sounding headsets, then pull the trigger and buy this one. You will not be disappointed.
