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!

These are like a lot of Sennheiser's other products. It has that signature sound profile that I only hear with Sennheiser. As for the ANC, it's all right; it does very well in a room with many distractions. I'll give an example. I have a fan in my room with ANC on I will not hear that thing at all. Which is very good, but when I'm riding in a car I can hear the radio and people talking, which isn't a big deal it does reduce quite a bit of noise, but nothing that completely ruins my listening experience. Another issue I have with is a product and the reason I can't give it 5 stars is, at times I have issues getting them to connect with my Mac laptop. The good is that once I get them connected, I have no issues, but sometimes I have to turn Bluetooth off, and put them back in the case, and take them out to try again. From a $300 dollar product, I would expect no connective issues so there is that. - ( works very well with phones have had no issues). The next thing is the case I love the thing it feels premium. The magnet is strong so unless your case, God forbid, drops on the ground, you have less of a chance of losing your earbuds. The last thing I want to mention is the app. It is a very well-designed app that offers a ton of customization for your earbuds. from sound quality to fit test Eq auto-pause when you take them out of your ears, a locator for the earbud in case you lose them, and many more. I am pleased with how Sennheiser has optimized their app for consumers, and I hope other companies will follow suit. Pros - great case - great sound quality - great app Cons - connective issues with Mac laptop - price - Only okay ANC All in all, I would recommend this product to anyone who wants to try this product, especially with Black Friday around the corner. 4.3/5 Will update this review after owning it for 3 months. So I've been using these earbuds for a little over 3 months. I officially can't recommend these products anymore. I have had a better experience with ToZo earbuds compared to these 300 E-waste earbuds. Not only does the Bluetooth disconnect randomly at times. I had many mornings of waking up to them not charged or close to 10% charge. I tried to love this product, but I can't with all of these serious problems that are hindering this product. Please, Sennheiser, do better. I think you guys have the best sound profile. I loved the PXC 550, but this is just sad.

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.

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.
