This is a Review of Sennheiser Momentum 2.0 Wireless Bluetooth headphones (M2 AEBT). http://en-us.sennheiser.com/momentum-wireless-headphones-with-mic , also available on Amazon: http://amzn.to/2h7RoFU
While waiting to receive my review unit of recently introduced Sennheiser Momentum 2 Wireless headphones, I was both excited and a bit concerned. Personally, I thought it was a risky move for Sennheiser to make a leap from a wired headphone world where they are a well known audiophile player and into a wireless universe dominated by products fueled with celebrity endorsements and exaggerated bass. Wireless Bluetooth technology has been maturing year after year, and now with BT4.x and aptX codec the performance of BT headphones have improved significantly with a sound being less compressed, more dynamic, and with a better transparency through a digital domain delivered to your headphones. But you still need to consider D/A conversion, amplification, and transport of analog signal to your headphone drivers. This fusion of digital wireless domain and analog driver tuning is the biggest challenge to tackle in order to deliver a transparent natural sound, something Sennheiser wired headphones are well known for. So, was Momentum 2 able to accomplish this wirelessly? You BETTER BELIEVE IT!!! Here is what I found.
Arrived in a sturdy cardboard box packaging, I had to pause for a second while looking at the cover picture. Even so it was a familiar image from my review of the original wired Momentum, I still took a moment to enjoy sexy lines of their design. Before opening the box, I usually like to take a tour around it to get acquainted with key features, list of accessories, design details, and technical spec data. Some of this info really stands out with key features of 22 hr battery life, BT + aptX support, NFC pairing, Active Noise Canceling (ANC), foldable design, wireless and wired connection, and 2 year warranty – quite an impressive list to get you excited for what awaits inside of the box. With a cover off, you will find a compact case made out of a soft material (kind of reminds me of suede texture) inside of a foam cutout, a familiar display setting I found with other Momentum models, though case material usually varies.
Unboxing.
In addition to this soft touch case with a yellow stitching around the edges, other included accessories (all inside of the case) were a detachable audio cable, usb to micro-usb charging/data cable, a flight adapter, a soft draw-string pouch with headphones inside and the pouch placed in the case, and a comprehensive quick guide. Personally I prefer a more heavy duty hard shell case and eventually will look for one which shouldn’t be a problem to find since Momentum 2 has a foldable design, but I do have to admit this case looks really sweet with a yellow stitching matching the one used on leather headband. Audio cable has a right angled gold plated slim connector going to your audio source and 2.5mm twist-on connector going to earcup. This is the same connector used in the original wired Momentum, and my only comment here is that I would have liked to see some kind of an alignment marker so you know when connector is engaged and twisted correctly inside of earcup, but with a few tries you get used to it anyway.
Flight adapter is rather rare to see nowadays, but it also very appropriate since a lot of people use headphones with ANC during their travel, and sometimes you're required to turn off Bluetooth on a plane (putting your phone in airplane mode). Having a wired connection gives you the flexibility to use headphones when battery is low or when you don’t have access to Bluetooth or in a situation like an airplane. USB to micro-usb connector is obviously for charging, but there is also another undocumented feature which I’m going to talk about later in the review.
Accessories.
I already mentioned that unfolded Momentum 2 looks just like its original predecessor. You get the same stainless steel metal arc headband, split at the top, partially wrapped in premium leather with a dense foam padding inside and yellow stitching around the edges. Instead of a typical height adjustment mechanism and headphone yoke, you can slide the earcup up/down across a slit of exposed stainless steel headband sides. The sliding adjustment is very fluid and easily controlled with one hand without being too tight or too loose. The earcup itself is attached to a mounting pin and has a full 360deg pivoting rotation to adjust comfortably to the anatomy of your head and your ears. This adjustment mechanism has a pure German engineering quality written all over it, and at the same time it has a very fashionable modern-classic look. The wires from earcups going to headband are flexible and still have a heavy duty shielding. At the point of their entry to headband you will find 4 metal screws for additional security.
One of the most noticeable design changes introduced with Momentum 2 (both wired and wireless) has to be a foldable headband. Such mechanism is easy to implement with a traditional headband where you can design-in foldable hinges. Looks like Sennheiser decided to challenge themselves keeping the original design, making it look identical from outside, and adding a durable locking hinge on inside right at the point where leather band wrapping begins. This is another example of well executed German engineering - done with a slim hinge which is hardly noticeable from outside. The only comment I have here, you have to be careful when folding earcups in to make sure metal endpoints of the headband don't brush against leather earpads.
And speaking of earpads, you will be pleased to know these have been updated with a bigger opening in comparison to the original Momentum headphones. I never had issues with those original Momentum earpads, though my ears are just average and about 60mm in height. For me with original earpads it was tight but still comfortable. The new earpads are just perfect with an approximate opening of about 65mm in height, but that doesn't mean that 70-75mm ears won't fit in. The earpads are deep, with memory foam and a soft leather wrapping. According to a quick start guide, they are removable and replaceable, so it's definitely a big plus. The donut shape of earpads is not symmetrical where the thicker part is faced toward the back making fitment more comfortable. This also means that you can't flip left/right sides and always have to put headphones one way. The L/R marking is inside of the headband, right underneath of the hinges, and you also get 3 dimples on the outside of the left side at the folding edge, though I wish those dimples would be a little bigger for a “blind” id.
Looking closer at earcups, you will find the Left one having NFC pair up area and what appears to be a two microphone grills. A spec of M2 Wireless lists NoiseGard hybrid feature using 4 mics where I assume these are two of them. Right earcup is where you will find the actual controls. First of all you have a port for 2.5mm cable with twist-on lock, and also micro-usb port for charging and USB DAC input (more about it later). As a right handed person, I prefer cable attachment on the left side, but it’s not an issue moving forward since I’m planning to use these headphones mostly wireless. Right next to it you have another long microphone grill and 2 control buttons. One is a Power button (with led next to it) which also serves a purpose of initiating BT pair up once you hold it down. The other control has a spring-loaded rocking multifunction push button where you push it once for Play/Pause/Call and rock it up/down for a volume control. Furthermore, double and triple click while playing audio will trigger skip track next/prev, and double click and hold or triple click and hold will trigger a fast-forward/-back transport control. In idle, triple click informs you about battery status.
