Sennheiser Consumer Audio Momentum 4 Wireless Headphones - Bluetooth Headset for Crystal-Clear Calls with Adaptive Noise Cancellation, 60h Battery Life, Customizable Sound, White (509267)

After a couple of months of listening to various music, calls and meetings, I'm very happy with this product. The sound quality is generally excellent, calls are clear and mics work as expected, battery life is outstanding and managing sound preferences are easy to do with the Sennheiser app. These are also a bit more comfortable to wear over extended hours than I expected. As in most/all cases with music, the source material quality, headphones setting to low res or high res audio & Bluetooth or wired connection will make a difference in sound quality. Impressed with the quality/detail of music over Bluetooth covering a wide range of music. The app usually works well and my minor gripe is that the app seems to require "refreshing" at times after stepping away from the phones for 15 - 30 minutes. After re-enabling the app, control actions on the right ear work as designed again. The motions on the right ear cup are also a bit more sensitive than I expected. Overall, very happy with the experience and recommend.

I just received these Sennheiser Momentum 4 cans about 7 days ago. I bought them for $270, and now I see you can get them $20 less. I made the purchase, despite the negative reviews posted on Amazon simply because I have learned that reviews don't tell the whole story. Such as often times when it comes to Bluetooth devices, there will be a new firware/update that will need to be done, depending on how old the product is. In my case, that was the case. The firmware update was easy, took maybe a minute or two, and I was off and running. I have owned, and sold several headsets, from JBL, Beats, SkullCandy, Sony and yes, Bose. Now, for me, and how I like my music to sound, the Sennheiser 4s are by far the best sounding Bluetooth headphone to grace my melon. Mids, highs and lows work amazingly well. Wind and string instruments sound crisp, and suppurb! The lows/bass work harmoniously with the above mentioned. The Sennheiser equalizer is easy to use, and gets the job done. Touch controls: they take getting used to, but, once you adapt, it works great. Yes, at times you may pause music when touching the right ear cup, but again, you will adapt and recover. Comfort. These cans are extremely comfortable. Even for my large head. Ear cushions are comfy, as is the head cushion. Could it use more cushion? Maybe if you wear them for 8 hrs straight. Weight. Yes, they way a tad bit more than the competition, but, that is to be expected as the battery is slightly larger...hence why you can get up to 60hrs of life on these bad boys! The cans don't feel cheap, they feel solid. And that is something I can appreciate. Are these cans perfect? They are as close to perfect that you will get (IMHO) on Bluetooth headsets. Are there better cans out there? Sure, If you go wired, and spend a few hundred more, then yes. Even Sennheiser wired headsets (depending what model you get) are better, but that's because they are wired. Of course they will sound better.One thing I didn't discuss is noise canceling. They get the job done in fine fashion. I have tried the Sony 5s, and they are slightly better than the Senn 4s. I have made several phones calls, FaceTime calls and the voice activation works wonderfully! I am 7000+ miles away from home, and not one complaint on how I sound, or, how the other end sounds. Lastly, battery life. It claims you can get 60hrs of life once fully charged. That is a fact, as I have tested that claim and 59+ hours the first charge, not quite there for the second charge. Mind you, it will lose an hour or two depending on what you have activated.Accessories. Well, you can listen to these cans wired, especially if you run out of charge. You will need a dongle (I purchased one from Amazon) and they sound great. It will sound different, and you may need to adjust you equalizer. The case the cans come with is a solid, good quality case with charging type C cable, 3.5 wired jack, and an airplane adaptor to plug your cable into so you can listen to movies or music that the plane is playing. And it all is neatly stored within the case.Final thoughts:I honestly feel that alot of the issues that some people reviewed on Amazon is these headsets have "buggy" issues, or connectivity issues. Perhaps some just don't know how to do firmware updates, the phone they are using is dated? Not sure, all I know is mine cans fired right up, and I did the update straight away. These cans have Bluetooth 5.2, so it should be able to connect to any device that's out there currently. Yes, touch panel does take some getting used to. Much like driving a truck, then driving a sport car. It may take a moment to get familiar with the vehicle, but once you do, it's a piece of cake.I decided to take a chance, I did my research outside of Amazon reviews, and watched the pros on YouTube, and that's how I ended up buying these. Big risk considering I am a world away. Give em a try, you can always return them if they aren't for you.

They're pretty good for the price, but they aren't the most dynamic or bass heavy. The audio sounds good and I enjoyed listening to a variety of genres on them. The plastic build feels lightweight but also cheap. The app is very good and it has good EQ customization. They're better than BOSE for example, but I think I will try out B&W after these.I think for this price range they are one of the better headphones out there. Certainly not a bad audio quality, just not good by audiophile standards.

Here's my opinion and rating after using these non stop for about a year nowAudio quality - 5/5The audio quality on these headphones are phenomenal. Straight out of the box they sounded excellent, and provide a great neutral-feeling sound signature without boosting the lows or highs too much.Comfort - 5/5The headphones fit very nicely and have rarely caused strain on my ears. The headband and foam around the ears are very soft. I have worn these for 5-6 hours at a time and have not noticed discomfortBuild - 5/5I've seen some people complaining about the build quality for the price, but I personally don't see their reasoning at all. The headset is made of lightweight plastic, but it doesn't take away from the premium feel and look. I love the fabric on top of the headband, and the version I have of these with the black-copper color scheme looks very fancy.Noise cancellation and transparency mode - 4/5The ANC is nothing notable, but it is far from bad. I have brought it on planes and had no issue with the noise levels. Transparency mode also works great.Battery life and charging - 5/5The battery life on this is insane. I can go about 2 weeks with constant use before I need to charge. They advertise something like 60 hours of battery life, and even while using ANC the headset delivers.Connectivity - 4.5/5The reason I rated this a 4 is because I have had some issues with my headset connecting to my devices. Every so often my headset audio will cut out every couple of minutes for about a second. It's not a big issue, as it eventually remedies itself or I can just power my headset on and off to stop it, but it was worth noting. Other than that, connection is pretty smooth. I do like how my headset switches automatically between my phone and computer to whatever device is playing audio at the time.Extra features - 5/5The app feels well-integrated with the headset, and it provides many options to customize your listening experience. I changed the touch control inputs on the side of the headset to feel more intuitive, as well as turning off some features I personally found annoying like the on-ear detection. The EQ also allows me to create my own sound signatures, and as a result I usually have the lows boosted.Other notable things -I haven't had many issues with the touch controls, and although I probably would prefer buttons, this works just fine.The headset does have quite a large footprint when packing, so I wouldn't recommend them for travel unless you have space.Putting it around my neck feels a bit awkward compared to previous headsets I've owned, but maybe thats just me.These work great for gaming, low latencyI'm just a regular user, not an audiophile. I mainly use these for listening to music and gamingOverall review - 5/5 (If you have the money for it)You'll have to sell your left kidney for these, but it's worth it for people who use headphones every day, all the time. There isn't a part of this headset that is not good, and it excels at being a comfortable pair of premium headphones.
