Third impression... Very Impressive
Edit.. We are going in for a third time on these boys. Not because I want to, but because they deserve it. !Using the personalized sound profile EQ is REQUIRED to get these to perform at their full potential but once you do, they open up beautifully like a decanted wine and turn into a different set of buds entirely. So my first impressions weren't spot on with just the normal EQ. (the other review clearly didn't take the time to use this feature and neither did I at first, they sound gorgeous afterwards.) After well over 30 hours listening time with these and going back to back to back repeatedly with Bose QC ultras and Jabra 10 elites... These are relentlessly impressive. I'm going all in, 5 stars. I will find myself saying, I want to know what this song sounds like with the momentum 4s if I'm using anything else.. So even my second impressions weren't spot on. The sound is just so crisp and clean with a stark separation between vocals and each instrument with sharp notes and rumbling bass (although i still wish we had an extra click or two of bass). You can hear every little detail perfectly. The jabras give you more bass, a more full bodied intense harmonious and louder sound but its not as clean and distinct. while the jabras have the passion, the momentums have the precision. the bose are just meh by comparison in everything except ANC and honestly dont compete well with either after extensive testing. These sound clean, crisp, tight, and full. It's like the artist is playing the music next to you rather than through a speaker. You can hear delicate parts of the music Bose and Jabra can't even touch. The momentum 4s give you a very pretty, intricate sound where the jabras give you a powerful bold sound, so depending on your taste and type of music you like, jabras may be your preference. The momentum 4s kind of dominate on pure sound with the extra EQ although I stand by that the ANC is average like sony/apple etc and isn't a huge difference between it being on and off. The fit and passive noise cancelling is phenomenal so you get pretty great performance overall, just not like Bose which is like turning the world off. Maybe someday other companies will crack the code like Bose did. The software is beautifully designed with lots of customization features, a very cool personalized sound profile which drastically changes the sound potential of these buds and you need to take the time to use it! Fully changeable touch features, other audio goodies people like. they are extremely comfortable over long periods, have a nice masculine clean look, touch controls are great and responsive, they connect to 2 devices seamlessly. zero connectivity issues, solid battery life, beautiful english accent to the voice prompts. case is great and i like how its not slippery as its covered in weaved fabric. they are encroaching on perfection. They could use a little more bass and ANC needs work. They don't get quite as loud as others but I just turn them up higher? You won't be maxing them out I can't imagine. if you really appreciate music and want to feel like the music is in the room with you and hear every detail clearly, these are a winner. Easily in the fight for the top ear buds in 2024. They could be the best for you depending on your taste. ... show more

Unreliable & Worst Customer Service
Let me start off with the pros. They sound great, and their app lets you personalize the audio however you wish. The fit is snug and the earbuds never fell out. They also last quite a while before needed to be recharged. And the quality LOOKS great. That’s about where the pros end, and the cons begin. First off they don’t sound much better than AirPod Pros, and yet they’re $50 more. Then comes the worst part - the reliability. I had these earbuds for roughly 2 months before they started having issues, specifically the right earbud. At first it would struggle connecting and wouldn’t charge at random point even though the left one was doing just fine. Then, roughly around the month and a half mark, the right earbud stopped working completely. Would not charge, play music, or even connect. It was completely dead. At around the 2 month mark, the left earbud followed suit. So I sent in the earbuds to one of their warranty claim centers, and it has been a downward spiral ever since. I’ve have dealt with customer support many times before, but this has to be the worst customer support I’ve ever dealt with. Here’s why: First off, finding their support number is not easy, as Sennheiser does not have a support center now that they are owned by Sonova. And to find their RMA website is even more difficult. Next, I never received any updates on the status—not even an email confirming receipt. I called shortly after the earbuds were expected to be delivered to check if they even received it and was told that they did but the facility is “offline” meaning they will only email you once the package has been sent back to you. On top of that, they informed me that it would take roughly 2 weeks (10 business days all in all) to get everything dealt with. I said okay and moved on. That wasn’t the end of it. Sennheiser finally emails me to ask me for proof of purchase, to which I quickly reply with a screenshot of the purchase details from Amazon. In the email it said that if I did not reply within 5 business days of the email, they would send back the earbuds. Now, 4 business days later, I receive an email saying that the receipt did not the proof of purchase details necessary, giving me less than a day to deal with this. Last thing to note, I did some research when I started seeing these issues and it appears that the malfunction I had with my earbuds has been around for a few years now, ever since their 2nd series of these earbuds. It’s clear that the issue hasn’t been fixed by Sennheiser since then. Overall, I would not recommend these by a long shot. I always heard everyone praise Sennheiser’s headphones and earbuds so I thought it would be a smarter buy than AirPod Pros. Unfortunately I am now regretting that decision as the AirPod Pros would’ve lasted me far longer and Apple support would have dealt with any issues much more efficiently than these people have. ... show more

So, I came from Sony xm4s which fried (loved those buds) I was stricken with whether to upgrade to the Sony xm5 or switch off. Found this in comparison videos and glad I did. These are better than xm4s. If you were comparing both I know it's a hard comparison. The battery is great, noise canceling is better than the Sony 4. With music playing you can't really hear the world (even walking next to heavy traffic. I took a call next to a busy road and the caller told me it almost sounded like I was in a quiet room assuming I was still at work though I was next to the road which is interesting. I could hear her perfectly fine too. I haven't played with their equalizer it's stock right now. I was a bit conflicted by sound quality initially. It sounded good but I felt something was slightly missing. I changed the standard on my phone to the hi res aptx. I have a Samsung s22 ultra (upgrading to s24 ultra soon) and the quality improved despite hearing Samsung shouldn't support that. Unless it's better but not true res or there was a supporting update idk. But it sounds just about flawless. Idk what the Sony xm5 sounds like but I know the controversy surrounding it. All in all I'm very happy. Also, I haven't noticed any hissing sound I've heard past reviewers mention though I heard an update addressed it. I'm very very happy.... last thing only negative. Sometimes they do wear on my ears. My ears do get tired (sometimes) a bit bulky but they fit very good. I don't have small ears, if you do Goodluck. ***Update- about 2 years later. So these bad boys fried roughly 2 years in started crackling and audio went out. They were used daily and very heavily for many hours. What I can say is I've dropped them several time on concrete etc. They been out with me in the conditions. I live in Vegas. I believe what fried them eventually was heat and possibly sweat getting inside. They fried one at a time right then days later the left. Luckily It was prime day and I got my new ones the next day after the left went out a wopping 150 dollars cheaper for 200. I usually always upgrade when I need to so this is rare for me to pick up the same pair that fried on me. However my experience with them was phenomenal. Nothing lacking. Case always sturdy reliable just darken with age and wear but still looks good despite it being a fabric feel. Sound quality great throughout the 2 years. It literally felt like im putting my old pair back in with the new ones. So.. why I didnt upgrade to another brand? Couldn't find any worthy to fit my preferences, and I do very heavy research. The sennheiser buds stayed strong till the end. Again I believe the elements eventually caught up to it. Fit and sound is always subjective but these were always great for me. Hope to make these last and upgrade beyond this pair. Side note im splurging on over ear headphones for my at home podcast/ music from beyerdynamics. I aaaalmost picked up the HD 660s2 from sennheiser which im still drawn to but wanted the more premium headset build. These earbuds are my go to daily. Went from copper to black as shown in pictures. ... show more

There are definitely other options in this price range with better sound quality
Color: Black
Sennheiser MOMENTUM True Wireless 4 IEMs feature a 7mm dynamic driver, wireless connection and noise cancellation, allowing you to switch between ANC and aware modes. The wireless design can be both an advantage and a disadvantage. Modern DACs can deliver excellent quality in a tiny package, but having the Bluetooth receiver and DAC inside each earbud means there’s less room for additional or larger drivers. And it shows—this model has the least impressive drivers of the IEMs I tested recently: just a single 7mm dynamic driver in each earbud. A single driver can be fine, if it's a planar driver. Planar drivers in my opinion are a revolution in headphones and IEMs. Unfortunately, Sennheiser MTW4 use a dynamic driver. To be honest, in my experience, really good sound in IEMs starts at $300, so I didn't have much hope for this Sennheiser model which I got for $200, but which often costs closer to $300. But my friend highly recommended them. Plus, they have powerful bass, and after buying 2 x 18" subwoofers I've temporarily become a basshead :) I'm sure this bass addiction will pass, but for now I'm enjoying lots of ultra low bass. So, the first thing I did with the Sennheiser MTW4s was to test the bass response. It's truly powerful and amplified. I checked the frequency response graphs, and at 20 Hz it's about 4 dB higher than on my favorite Fiio FH9. So for bass, these are good. The second positive thing is that these IEMs are not fatiguing. I didn't notice any peaks at any frequencies (besides the bass, obviously). Third, they fit comfortably. Unfortunately, for me, that's where the positives end. On to the negatives: The downside of non-fatiguing sound is that it feels muffled, dull, too warm, and has softened highs. Secondly, instrument separation isn't great—these can't compete with truly high-end, expensive IEMs or headphones. Third, the soundstage feels too narrow, again compared to pricier and better-performing IEMs. Fourth, the max volume is probably the lowest among all IEMs I've ever tried. And finally, while the bass is powerful, in my opinion, its quality isn’t great. It’s not very tight, and it doesn’t remain clearly separated when multiple instruments are playing. This difference became especially obvious when I compared the bass to my next contender—the Campfire Audio SuperMoon. I don't want to bring even more negatives about Sennheiser... I love this company, and they produce some of the best headphones and IEMs in the world. For example, their HD800 open headphones got the 2nd place in my selection of headphones in $2000 price range (HIFIMAN HE1000 v2 won for me and I kept them). However, I feel like Sennheiser got too comfortable with being a leader in the world of hi-fi headphones and they start losing the battle to relatively new brands, like Chinese Fiio or HIFIMAN, or some US brands, like Dan Clark. These competing manufacturers constantly increase the sound quality by using multiple drivers, or using planar drivers, or using new revolutionary technologies. Dan Clark, for example, uses exclusively magnetic planar drivers, and are renowned for delivering a sense of openness and spaciousness (in their closed headphones) typically associated with top-tier open-back models like the Sennheiser HD 800 S or advanced HIFIMAN models. This "open-like" quality stems from a combination of innovative engineering, precise tuning, and materials science that minimizes the usual sonic drawbacks of closed designs—such as boxy resonance, compressed staging, and veiled highs—while retaining isolation benefits. Sennheiser, for some reason, is not really growing or improving. For example, one of their top IEMs: IE 600 (costing $700 - $800), also uses just a single 7mm dynamic driver. I'm afraid if it continues like this, Sennheiser may go out of business if they don't start improving rapidly. ... show more

Top 3 Best Sound for Buds
Color: Black
Review Image by Mr. Amazon

Review Image by Mr. Amazon
BACKGROUND: I love sound. An 11.1 home theater system is my reference, and due to my love of movies, deep, rumbling bass is my preference. Music requires more precision in a subwoofer (sealed vs vented enclosure typically), but if I can only have one, my bias is towards theater use. I also prefer "bright" speakers over more neutral or warm, so Klipsch is a favorite of mine. So, the bronze on black Sennheiser Momentum 4's tugged on my heartstrings a bit. COMPARABLES: I've previously had Samsung buds (Buds Live and Buds2 Pro) due to their integration with their phones, but was looking for better sound. I've had Sennheiser wired buds before and loved them, but was also interested in the Technics AZ-80's due to stellar reviews. I also looked into the Denon PerL Pro's, but they didn't make it into my cart due to their large "dinner plate" design. They get rave reviews for sound quality, but I draw the line on aesthetics somewhere. SOUND: So, the shootout was between the Technics and Sennheisers and neither is a clear winner. The Technics sound a bit more natural and "cleaner" while the Sennheisers sound more punchy and lively. Both sound great, but if I had to pick one for overall sound for every application, I'd lean toward the Technics. They just sound clean and detailed. The Sennheisers are more customizable however. The app really let's you tinker with the sound profile, especially after you set up an account (a must for all the extra features). Out of the box, Technics sound better, but with adjustments, the Sennheisers close the gap. The Denons require tinkering as well to get them fine-tuned to your ears. FEATURES: The Sennheiser app is much more robust than the Technics app. Here it's not close - Sennheiser is a clear winner. Changing settings, customizing the eq and sound profile, and adjusting parameters is pretty straightforward here while a bit less so in the Technics app, which is a bit less intuitive to use. The ANC is ever-so-slightly better on the Sennheisers, but not enough to make a decision on that alone. FIT AND FINISH: Both sets look the business, but the Sennheisers are lower profile and fit more securely in my ears. Every ear is different, so this is a "try before you buy" situation, but for me, the Sennheisers were a clear winner for fit. The Technics case is petite in comparison however. It slips in a pocket and feels svelt while the Sennheiser case feels enormous. The cloth texture is a unique and premium touch and I'm a fan... But the size is noticeable. The charge port is also on the front, which I don't like whereas the Technics puts it in the back where it should be. The charge light is also better on the Technics, both in form and function, having a light on the outside and inside of the case showing battery and charge status. The Sennheisers only have a light on the outside of the case, partially obscured by the charge cable if plugged in. Technics case is a clear winner. VERDICT: Both of these buds are great, and each have their pros and cons. I like the fit and app of the Sennheisers way more than the Technics, but the Technics case is better and the sound is better out of the box. Technics' Three point pairing is an added bonus, but only at normal sound quality, which makes the feature moot for me. Technics seem to have a bit better quality control with less reported issues, but I'm hoping firmware updates have sorted out most of the kinks by now. For me, the Sennheisers simply fit my ears better and the app made it overall a much more pleasant experience. With some tinkering, I might be able to fine tune the sound a bit more and make them the winner in that department as well. The Klipsch (or Duracell) color scheme is pretty sweet on the Sennheisers, but the silver on the Technics is slick as well. ... show more

Amazing Earbud But Not Perfect
Was definitely wary with all the high return rate and review. I really wanted this pair with Bose and Sony as alternative. Figure I can return if needed. 4-Star as it's not perfect product and does have issue. At this moment, I plan on keeping these earbud. Here my experience with it. Case - Really nice cloth quality case - Charging LED is on the left side of USB-C. I wish it was on the top middle. - Size is about 7cm L x 4cm W x 3.5cm H. A tad bigger/bulkier than other case. Pairing: -No pairing or discovering issue. -Able to connect to my PC with Sennheiser dongle and S23 Ultra. - Can use each bud independently BT Connection Range - ~15-20ft. Battery Life w/ + Multipoint + 50% volume level + ANC off - About 5.5hr with Low-Latency Resolution. -Battery ECO Mode: I don't see myself using it but assume it would add 1-2hr - At 10%, you get alert of “Recharge Headset”. You can turn this alert to Tone Only or Off. Audio Resolution -Standard (default): I recommend to NOT use this. I get like ~7 crackling per hr. Most likely one of the reasons why many people are returning. -Low-Latency: No crackling in 5.5 hr movie session. Experienced like ~5-8 crackling in a 5 hr Live Stream. Way better experience. I feel like the crackling was due to video cycling with different audio rate and possibly streaming platform limitation. -Hi-Res and Lossless: No issue with movie, music and gaming. Same issue with streaming video above. Multi-Point: -Switching between PC dongle and Phone can give initial crackling/static for like 3-4 sec mainly on PC with Standard resolution. Low-Latency/Hi-Res/Lossless did not have this issue. -Seems like you must pause device 1 before it would connect to device 2. -No/minimal delay in connectivity between switching device. Wearing - Did not fall with vigorous head shake or light workout like jumping jack. I could feel it bounce like it going to fall out but it did loosen at all. Audio Quality - Amazing with crisp and clear audio from video, music and game. - Noticeable difference between S23 Ultra which doesn't have aptX codec and the PC with BTD600 dongle. The PC is better but the S23 is also good. - Gaming Fit Test - The pre-install ear bud was seemingly perfect fit for me but Fit Test deem it as invalid. Switching it to another size gave Good Fit. Repeat test can sometime change the result to like Poor/Fair Fit. - After 5 hr of wearing, I switched back to the one that was "comfortable" for me due to ear pain. So just use the Fit Test as a reference guide. ANC & Touch Control: - Have option of: Off/On or Off/Anti-Wind. - ANC seems average. "On" is better than "Anti-Wind" at noise reduction in my opinion. It reduce like my AC sound by like 80% and I cannot hear the AC with "tranquil" music playing at 70% volume. Transparency Level (hear through): -Has a slider and works with no issue. Touch Control: -x1, x2, x3 Tap and Hold. -Can customize each ear bud independently of on another. -Cannot customized touch control setting during phone call. x1 tap for Accept/Mute. x2 tap for Reject/End. Equalizer - Option for Bass Boost or Podcast - Has dB band slider for 63Hz, 250, 1000, 4000, 8000 (not for the average user to tinker with) - 7 preset for different genre (Rock, Pop, Movie,Jazz etc) and customize. Sound Zones -Allow to automatically change your sound based on your pre-configure location (i.e. home, room, basement etc) ... show more

They're great until they aren't
Color: Black
These earbuds work well and sound good. They're comfortable to wear for hours at a time. They charge quickly and the case is small enough to keep in a pocket for convenience and charging in the field. The biggest problem I had with them before now is that even putting your hand between them and the device they're connected to could sometimes disrupt the connection severely. For example, if I have my phone in my pocket the connection is fine, but if I put my hand in my pocket with my phone it interferes badly enough that I can't understand what I'm listening to. Unfortunately, 1 year and 1 month of use and the right earbud literally fell apart. The half with the charging connections separated from the rest of the unit. I thought I would be OK with just the left unit because I don't often use both of them at the same time anyway, but a few days later the left earbud now won't stay connected to my phone. I don't know if the left earbud requires the right to be in the case and charged to work properly or not. I've used the left on its one a few times before, but never when the right was completely dead as is now the case. I got a little over a year out of a nearly $300 pair of earbuds. I got them on sale so it could be worse, but it is not the quality I expect from a premium priced product. I am now looking for a new brand to put my trust into. ... show more
