My review is based on the comparison with the Bose QC45 as I needed a clear winner and see which one to keep. At first, I got the Bose Qc 45 while they were on sale for $229 on Black Friday, and got the momentum for $300. I take the subway every day going to work, and that's where I tested both QC 45 and Momentum 4. There are my conclusions: When it comes to the Bose QC 45: The comfort is just DIVINE (Piccolo approved ;-) ) ! the Bose QC 45 is SO LIGHT that I easily forget that I have them! I have no problem wearing them for an entire day without any fatigue! they are that light and comfortable and you barely remember that you wear them and are my always go-to! The sound quality is FANTASTIC (I just wish it had more bass), the EQ won't bring a drastic change but it's a welcome feature. The ANC is just TOP TIER as someone who takes the NYC subway every day, I always enjoy my music and podcast while on the train. Transparency is Great but not airpod max level. Now let's talk about the Momentum 4: The reason why I bought the Momentum 4 is that I needed my sound to be a bit louder and I wanted more bass without paying the price of the Sony XM5, moreover, when it comes to calls, the Bose 45 is not the best when you are in a noisy/ windy environment (subway and street) and I got quickly frustrated on calls as people would constantly have a hard time listening to me. The Momentum 4 has AMAZING SOUND QUALITY (better than the Sony XM5 but that's for you to appreciate) ! The bass is crazy, all of that without touching the EQ (when you play with it, it's even better) !!! The comfort is close to the Bose QC45, however the clamping force is a bit strong vs the bose, and sometimes you will need to take them off to relieve your head of the pressure, but Bose stays way ahead in terms of comfort ( as I said Piccolo approved) and can be worn for an entire day without fatigue ( for me ) , and the call quality with the momentum 4 is just GREAT and very close to the Sony XM5, I made phone calls while in the subway with trains passing by and people on the other side of the line had no problem listening to me (what a relief !) ! No one ever complained about how I sounded. The battery is just crazy almost 3 times the Bose (60 hours) ! ANC is Top tier too, and so is transparency but still not Airpod max level, but enough to hear your surrounding properly. my biggest issue with the Momentum 4 which is a big strength of the Bose is Bluetooth Connectivity and power on and off. Several times I had to check if the headphones were connected to my device or I had to turn off and restart the headphone to be sure it was connected, an issue I NEVER HAD with the Bose (just switch on and press play). Sometimes it's hard to know if it's ON or OFF as it turns on automatically and it's a bit confusing to know wether you really switched it off or not. I hope Sennheiser will address that with a software update. A personal one : I wish the momentum 4 had more buttons like the bose ( easy to operate in any season and no room for confusion) Do I recommend the momentum 4 ? ABSOLUTELY! What about the Bose QC45? Perfect Comfort , great ANC (the best for very long listening and travel).

Absolutely adore these headphones. I purchased them on a pretty deep Black Friday discount, as I was looking for over-ear headphones to use in university for studying and the like. Pros: - Wonderful sound quality - BY FAR the best I've heard in any Bluetooth headphones. Additionally, the wired options improve it even more. - Excellent build quality. These headphones are incredibly comfortable and feel very "premium" (if that word even still has meaning). They do not feel flimsy and feel very well designed. - The battery life. The battery is excellent. I have not once ran into an issue with the battery. - Touch controls. This is an area I've seen a lot of contention about online. I have personally found them to be very intuitive, and I've had little to no issues with them in the month I've been using these headphones. I am someone who has longer hair and likes to lie down, and I've rarely if ever had any unwanted inputs. Additionally, the controls respond well. I think the inputs are a bit precise, which may be an issue for some. - The look. The brown color is a little bit darker than it appears in online, and I think they are absolutely gorgeous. They are very easy to accessorize with, and if you're someone that wears earthier tones like I, this is the color you want to go with. Cons: - The noise cancellation. This is not incredibly important to me, but if noise cancellation is your biggest deciding point (which, these are noise cancelling headphones) I would suggest looking elsewhere. It is not bad, but there are certianly better on the market. I find that my AirPods Pro 2 beat them in many scenarios. - Windows PC usage - I primarily use Apple devices (iPhone, MacBook) and they are incredibly seamless and connect easily for those. However, I also use a Windows PC, and they seem to have some issues with that. It is resolved, but sometimes it's a couple minutes of messing with them until they work. Never unbearable, but a minor inconvenience. Overall, I find these headphones incredible. The sound quality is unlike any other bluetooth headphone I've tried, and the wired capabilities bring that even higher. Despite lackluster noise cancellation and Windows connectivity troubles, these are minor grievances to me and they more than make up for it elsewhere. I would highly recommend these to anyone looking for quality over-ear headphones.

I recently got the Sennheiser Momentum 4 Wireless headphones, and after weeks of using them, I can confidently say they’ve exceeded my expectations in almost every way. Whether I’m working, commuting, or just relaxing at home, these headphones deliver an unbeatable experience. Comfort and Design: Let’s start with comfort—these are some of the most comfortable headphones I’ve ever used. The ear cups are super soft and fit snugly without feeling tight, even during long listening sessions. The lightweight design also means no fatigue after hours of wear. While the look is more minimalist compared to previous Momentum models, I actually like the understated style. It feels modern and premium. Sound Quality: The sound quality is phenomenal, as you’d expect from Sennheiser. The audio is rich and balanced, with crystal-clear highs, smooth mids, and deep, punchy bass. Whether I’m listening to classical music, hip-hop, or podcasts, the Momentum 4 adjusts beautifully. They also support high-resolution audio codecs like aptX Adaptive, so streaming from services like Tidal or Spotify feels like a live concert. Active Noise Cancellation (ANC): The ANC on these headphones is top-tier. I’ve used them in noisy environments like coffee shops, airplanes, and even during commutes, and they block out almost everything. What’s impressive is how natural the transparency mode feels when I need to hear my surroundings—no weird robotic sounds. Battery Life: The battery life is insane—up to 60 hours on a single charge. I only have to charge them once a week, even with daily use. The fast-charging feature is a lifesaver, too—a quick 10-minute charge gives several hours of playback. Connectivity: Pairing these headphones is seamless with Bluetooth 5.2. The multipoint connectivity is a game-changer—I can connect to both my phone and laptop simultaneously, which is perfect for work and calls. The touch controls are responsive, and the companion app lets you customize the sound profile to your liking. Use Cases: I’ve used these headphones for everything—music, binge-watching Netflix, taking calls, and even editing videos. The mic quality is fantastic for calls, so I never have to switch to another headset during meetings. They’re also perfect for traveling, thanks to the long battery life and excellent noise cancellation. Final Thoughts: The Sennheiser Momentum 4 Wireless headphones are worth every penny. They deliver incredible sound, unmatched comfort, and the best battery life I’ve experienced in headphones. If you’re someone who values premium audio and features that genuinely make your life easier, these are an excellent investment. I honestly can’t imagine going back to anything else.

Sound quality is top tier (with the use of the app, else it sounds flat out of the box). Sound quality is clean, spatial, and full. It feels like the singer is singing right into my ears. Each instrument is well balanced and placed; no instrument overpowers the other. ANC is very good too. I cannot hear the loud construction that's right outside. I come from the Skullcandy Crusher Evo which is specialized for bass and percussion. The bass and percussion on the M4s are exceptional, but are not as impactful and intense like the Evo's. This shouldn't be a concern for most listeners, but this is something to consider if you have a preference for bass and percussion. This isn't a dealbreaker but the sound quality is the best at high volumes (> 80%). Thankfully the ear pads are soft and comfortable. But wearing these for several hours at > 80% volume is definitely not recommended for the sake of ear health (which is obvious common sense for any headphones). My main deal breaker is I can hear more from my right ear. I wore the headphones backwards and could hear more from my left ear. The stereos are slightly angled, so the sound is the clearest when my ears are closer to the stereos. Regardless of how I wear it or what I listen to, I still can hear more from one ear. I checked my settings and nothing looks off. Other than that, I recommend the headphones for the A+ sound quality, 60 hour battery life, exceptional ANC, and comfortable ear pads.

As a long-time devotee of Bose accessories, I was hesitant to stray from my comfort zone. However, after more than a month with the Sennheiser Momentum 4 Wireless headphones, I'm happy to report that I'm a convert. These headphones deliver a compelling combination of superb sound quality, effective noise cancellation, and impressive comfort, making them a worthy contender in the premium headphone market. A Bose User's Perspective: I've been using the Momentum 4 Wireless for 8 hours a day for meetings, music, and everything in between. The comfort level is outstanding. I can wear them for my entire workday without any discomfort. This is a huge plus for me, as someone who spends a lot of time on conference calls and listening to music. Pros: Superb Sound Quality: Sennheiser's audio expertise shines through. The sound is well-balanced, with clear highs, rich mids, and punchy bass. Whether I'm listening to classical music or podcasts, the audio is immersive and enjoyable. Effective Noise Cancellation: The adaptive noise cancellation effectively silences the world around me, allowing me to focus on my work or lose myself in my music. The ability to adjust the level of noise cancellation is a welcome feature. Long Battery Life: With up to 60 hours of playtime, I can go days without needing to recharge. This is a significant advantage over my previous headphones. Comfortable Fit: The lightweight design and plush earcups provide exceptional comfort, even during extended use. Intuitive Controls: The touch controls are responsive and easy to use, allowing me to adjust volume, playback, and noise cancellation seamlessly. Cons: Design: While functional, the design is less stylish compared to the previous generation and my Bose headphones. App Experience: The Sennheiser Smart Control app can be a bit finicky at times. I've experienced occasional connectivity issues. No Folding Design: The lack of a folding design makes them a bit less compact for travel. Overall: The Sennheiser Momentum 4 Wireless headphones have won me over with their exceptional sound quality, effective noise cancellation, and remarkable comfort. While the design and app could be improved, the overall performance is outstanding. If you're looking for a premium pair of headphones and prioritize audio quality and comfort, these are definitely worth considering. Recommendation: If you value sound quality, comfort, and long battery life, the Sennheiser Momentum 4 Wireless are an excellent choice. Even for a die-hard Bose fan like myself, these headphones deliver a compelling experience that's hard to beat.
