SennheiserConsumer Audio Momentum 4 Wireless Headphones - Bluetooth Headset for Crystal-Clear Calls with Adaptive Noise Cancellation, 60h Battery Life, Lightweight Folding Design, Black (509266)

(Updated bottom)I want to start by saying I'm glad I went with Sennheiser despite the bugs early on & so on.I have yet to experience any issues with the exception of my dedicated BT transmitter I use for the TV but that happens with every pair or BT headphones I have so it's not a Sennheiser momentum problem.Keep it to one or two sources & only play one at a time my transmitter would create popping sounds when its connected to that & my phone both playing audio.The transmitter is the Avantre BT transmitter.Wanted to get that out of the way I'm also on the latest version of Android 15 & updated the headphones so I'm having smooth sailing & oh man I'm a audio snob but these can satisfy me.The bass is nice not like Sony were everything else sound muffled & you can control the EQ to your liking. For me I turned the bass down the -3.0 doing so gets these bad boys close to the Harmon curve. My only gripe are the mids but reducing bass helps a lot.The bass hits hard but never bloats like bears or Sony headphones will.Highs are crisp almost too much for me but theyre nice.Mids are there & can be improved as mentioned above.The fit of these feels like a glove & I will say they're big head approved I have a 24 1/2 size head & these are comfy if not a bit toasty after a while.Volume controls are nice & will work well once you learn not to over input.Bluetooth works well haven't had issues say for my transmitter mentioned above.Money wise I'd agree for the money especially on sell they're a steal & a good value.My final thoughtsI will absolutely be keeping these along with my B&O & HD600 headphones.That & the app actually works where as B&Os app is straight up grabage.Well done Sennheiser.While I still love these the sound is really nice but the earpads get hot & sweaty. The material is bad it gets every bit of sweat or face grease in them & they're a pain to it off. Again they sound great & are very comfortable as I like the higher clamping force but man the earpads are a pain they aren't peeling or anything just something to keep in mind. For a bit more context it's like the PU leather with greese & no I'm not a filthy person I shower & take care of myself but this is a lot of its more noticeable on these.I got some interference here & there but turning of my BT transmitter for my TV fixed that as I was listening to music on my phone.The case could be a bit bigger you have to fight them a little to get them on the case safely.With they sold larger options so I could keep my headphones a bit extended & not have to resize each time & there's not click or numbers present on the headband to get them sized right easily.I solved this by having a place on my closet shelf for them to lay safely out of their case.These updates are just me largely nitpicking but I thought it would be nice to share these as you might also experience them.Regardless I'm keeping them they to good & the plastic seems of higher quality then most use.

Let me say upfront I am a long-time audiophile. I've been immersed in all things high-end audio for more than 40 years, and listened to a lot of stuff, including headphones. Until recently, I've avoided all BT/wireless headphones because they presented too much compromise for my tastes. Noise cancellation adversely effected audio quality and/or gave me a headache. Bluetooth simply didn't cut it for prolonged enjoyment because of the lower, compressed resolution and frequency.But, that all changed in late 2022. On a whim, I tried the newish Sony WH-1000XM5 and was surprised at how good they sounded. The noise cancellation was excellent with little of the rushing elevator sound--and boy, the sound was terrific. For the first time I felt like using a wireless headphone wasn't a big step-down from wired. The M5's soundstage was truly impressive, rivaling my Focal Clear MG wired 'phones. Plus, the M5s were much lighter, more portable, and a bit more fun. The new Sony's were a magnitude better than the older Sonys, as well as anything wireless I'd heard before.That got me wondering: If the Sony's are this good, maybe something by Bowers and Wilkins or Sennheiser would be even better. After all, Sony caters to the mass market, which is generally not that discerning when it comes to audio. Whereas, B&W and Sennheiser typically aim more for the smaller, high-end, audiophile market. So, I started comparing the MX5 to the new B&W Px7 S2 and new Sennheiser Momentum 4 Wireless.Here's what I found:In the past, like the Sonys, the B&Ws and Sennheiser wireless 'phones were disappointments, falling far short (for me) of their wired, non-NC counterparts. No longer, because the new models are dramatically better. Without going into lots of detail (something audiophiles love to do), both the Px7 S2 and the Momentum 4 are a leap forward in every way than their predecessors. Are they better than the MX5, yes, but not by much. As others have said, the MX5 has better software, better NC, is very portable, and pretty comfortable. For many, the slight compromise in audio quality may not be a big deal. I could easily live with the MX5. However, my priority is sound quality since I seldom use NC, and, even if the software of the B&Ws and Sennheisers is only acceptable.Therefore, it came down to the Px7 S2 vs. Momentum 4 for me. The Px7 S2 is much nicer to look at, exuding high quality. The Momentum 4, not so much. In fact, they look like an MX5 knock-off with a few upscale touches. The software of both the Px7 S2 and Momentum 4 is mediocre at best, albeit functional.Now about the sound. The Px7 S2 sound really, really good. Bass, Midrange, Treble are all top notch, if not perfect. They're fun to listen to, with a wide soundstage and energetic dynamics. That said, they're tuned to emphasize the lower frequencies a bit too much for my tastes. At first, this makes music and voices more vibrant and robust, but, over time, it gets tiring, and you're realize what you're hearing isn't all that accurate. If I hadn't listened to the Momentum 4s, I probably would have been quite happy with the Px7 S2.But, I did listen to the Momentum 4. It edges out thePx7 S2 and MX5 with its overall excellent balance and accuracy. Nothing is exaggerated: voices, instruments, timbre, tone are all just right to my ears. Maybe not as exciting as the Px7 S2 upon first listen, but the Momentum 4s seduce you the more you use them. There's no need for lots of equalization, or fiddling to get the sound right; its all been done at the factory. Besides the accurate representation of voices and instruments, the Momentum 4s are monsters when it comes to soundstage. The placement of everything is wide, yet accurate. You can feel the space and air between different instruments, and where the singer is in the studio or stage. Layering and detail are pretty amazing considering these are bluetooth, closed-back 'phones. Sennheiser (Actually: Sonova, because Sennheiser sold their headphone division to this maker of hearing aids in 2021.) did their homework when it came to the Momentum 4. Plus, that 60 hours of battery life is icing on the cake.Let me say this in conclusion. You won't go wrong with any of these three headphones. They're all great. I preferred the Momentum 4 because it represents the overall most satisfying package for the money, but you might prefer the Px7 S2, or the MX5, more. One last word, regarding the buggy software of the Momentum 4: I found none. With the latest updates, Sennheiser/Sonova seems have fixed the issues of poor connectivity and consistency. All system functions worked perfectly the entire time I've been using the Momentum 4s. Enjoy!

I've been using Bose QC line for about a decade across several versions. I have several headsets that I've kept at work and personal computers as well as traveling. I decided to give these a try after seeing several good reviews and finding the Bose QC line is largely stagnant for better and worse in a few ways.What I like about the Momentum 4's is the sound quality first and foremost... I would put the sound as a bit more full than the Bose QC, which is surprisingly nice. The noise cancellation are about on par. I have a fairly large head, and they fit very well, not quite as comfortable as the Bose for me, but definitely not bad, and most people with probably not have any issues at all.Now for what I don't like... I don't like the gesture controls at all... If I do anything beyond start/pause I find myself having to dig out the card trying to remember. I'd much rather have a couple extra buttons on the side near the power/connect button. This is where they lose a star for me.All around the sound is definitely fantastic, fit is very good, but the controls could use some rework and maybe even some reversion back to more manual controls.I can't really speak to the mic quality as I'm mostly using them with a computer and on conference calls it's easier to use my webcam mic... BT modes for calls kinda suck, especially in linux and I just try to avoid it altogether.
