Sennheiser MOMENTUM True Wireless 4 Black Copper

I compared three earbuds in the same bracket: - Sony LinkBuds Fit - Bose QuietComfort Ultra - Sennheiser MOMENTUM True Wireless 4 Sony LinkBuds Fit 🟊☆☆☆☆ The tap controls are highly unreliable. When tapping a bus twice (carefully, directly on the earbud), it might register zero taps, one tap, or two taps. Thus, your two taps will randomly do nothing, pause the music, or skip the track. Frustrating. I perceived no improvement on sound quality over my old $50 Anker Space A40s. Furthermore, Sony's setup app is malware: it hides among the legal agreements an "Agree" to data sharing. I don't know what Wirecutter is smoking; I liked nothing about these. Bose QuietComfort Ultra 🟊🟊🟊☆☆ I was so close to loving these. The noise cancelling is incredible. The "Immersive Mode" brings music to life in a way I hadn't experienced with earbuds. However, the deal killer was that the earbuds would disconnect from my phone every few minutes. This is apparently a common issue. Additionally, the tap controls are better than Sony's, but still bad: you're supposed to slide your finger along it to change the volume, but this often registers as a tap. All this said, you might nevertheless want to try these with your phone and cross your fingers that they can stay connected, because the noise cancelling and sound is that good. If they work for you, you've won the lottery, and you're a lucky bastard. Odds are, though, it will be glitchy and unreliable for you, too. Sennheiser MOMENTUM True Wireless 4 🟊🟊🟊🟊🟊 Great, reliable tap controls. Noise cancelling and sound is not quite as good as the Bose QuietComfort, but still sounds great. Stays connected. Doesn't force you to use a crappy app. Comfortable. Has a premium look to it. Ultimately, you want earbuds that sound good, stay connected, and aren't frustrating to use. This is it.

This is my 2nd pair of Sennheiser earbuds and I will never buy any other brand. My last pair lasted a few years and that was with me using them practically at full blast every single day at work from 8-5 so the price is well worth it imo. My favorite thing about this brand is how customizable they are in both the fit and sound. My ears are an odd shape so it's hard for me to find earbuds that fit while also not being bulky and feeling like they're going to constantly fall out. The different tip and wing sizes they give are perfect for finding the right fit for any ear shape so they're comfortable enough to leave in all day. On the app you can also customize the sound you want based on your own desires or music style you listen to as well which is perfect for me. The transparency mode on these is also amazing so I can leave them in all day and just pause my music when I want to talk to someone and not deal with taking them out. And the battery life these things have is amazing enough for me to do just that! 10/10 recommend these!

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.

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)

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.

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.

TLDR fantastic sound but so many other issues. Go with the Sony's. Pros: Battery life. (Asterisk. We will get to this later) These used to last me as long as I wanted/needed and I could just charge the case every couple days. Was great. Top tier sound for the price. No comments here. This is what I buy Sennheiser for. Durability is fine. Case feels like a significant upgrade over last generation however it still feels kinda cheap. Cons: The software apps are abnhorrent. Why did I have to download a NEW app to control these when the old app had all of the same functionality? And now that I got the new app, the old app doesn't work of course. And the only thing you really care about with these apps is MAYBE changing the controls? That's it. Battery. I've owned these for about a year and the care if refusing to charge over 30%. Yay. Isn't that amazing. I have cleaned the contacts to make sure one of the earbuds isn't staying on when put in the case and draining the battery. I have factory reset them. I have left the buds out and let them die to force disconnect from the case. I have tried several different chargers and the result is the same: I get the blinking charging light but no actual progress. Sennheiser this is unacceptable for $300-$400 earbuds. If you don't fix these issues then a lot of people are going to leave for the competition.

I have owned the Sennheiser MTW2, MTW3 and now the MTW4. Previous to that, I used wired audiophile earplugs such as the Shure and Westone very expensive professional earbuds costing between $400-$900. I needed a wireless alternative, that would be also good for calls, and I tried Jabras, Sonys, Samsung, B&0. Notice that audiophiles never mention Bose, Beats, or JBL. If you like the latter, you prefer very altered music with augmented bass and highs, very V-shaped curve response, which is the most commercial thing to do, because it fits pop and hip-hop, the most popular genres. The Sennheiser will not be your best choice if you are accustomed to heavily altered music. An audiophile sound reproduction looks for a flat frequency response that will not exaggerate any frequency. Only a flat response will transport you to the acoustics of the room or hall where the music was recorded and will fool your brain into believing you are in that room, because it provides accurate representation of all the reflections on the materials. The MTW2 where the first earbuds that convinced me to go wireless. What Sennheiser was able to achieve with just one driver, compared with Shure and Westone 2, 3 and 4 driver earbuds I had before, is simply amazing. Even today the MTW2 sound really impressive. The only issues with it was the codec it could use, and the not so good ANC. The MTW3 improved the ANC, the codecs and added extra bass boost to compete with the commercial trend of making everything bass heavy. It did without sacrificing clarity, and I used the feature. The main problem with the MTW3s is a design flaw that makes buds get unable to get charge, and I had to send them back to repair, under warranty, twice. With the MTW4, I hope them fixed that design flaw, time will tell... so far I don't hear complaints. The MTW4 improve ANC and provide better codecs, including lossless codecs. Bear in mind this means it will transmit lossless over bluetooth; so it will not add loss to the original file. To be truly lossless you'll need a lossless file streamed with the lossless codec. I tried that, and the difference between lossless and high quality lossy is only discernible in very good recordings, and it does sound a bit fuller and more present. But the cost and inconvenience of having lossless music providers is really not worth it. I'm happy enough with the highest quality lossy setting. As it has always been the case with every earbud, I never care to use EQ, custom EQ, so I won't review that part. I make sure the phone is not set to 'enhance' the music using Dolby, or any assistance for people that are older. If the earbud doesn't give a good sound by physical means, it is pointless to try to fix it electronically; that just alters the original recording and will give your ears a sugar rush that will eventually make you insensitive to certain frequencies, and hungry for more boost. But I tried and it has decent EQ capabilities.
