Sennheiser Momentum 5 TWS review

The Sennheiser Momentum 5 TWS is easy to like for the reasons that actually matter. It has competitive noise cancelling, good transparency, a sensible redesign, and, most important, user-replaceable batteries in both the earbuds and the case. In a product category that too often behaves like a countdown to e-waste, that is not a small thing.

My hesitation is equally straightforward. For my own use, especially walking outside and hiking, I ran into a seal-related crackling issue that happened with ANC or transparency engaged, making bodily vibration from footsteps a bit of a problem. So this ends up being a very good earbud with one caveat that may or may not be a dealbreaker depending on how you use it.

What changed

Sennheiser went with a full redesign here, and the headline changes are Bluetooth 6.0 and the repairable battery approach. The battery is replaceable in both the case and the earbuds, and Sennheiser includes a tool for that. I think this is exactly the direction the category should be moving in, especially because battery degradation is not hypothetical on true wireless earbuds. It happens.

The stated battery life is also strong: up to 12 hours on a single charge and up to 40 hours total with the case. I can only report those figures as stated, but they are part of why the overall package stands out.

I also think the timing matters. Sennheiser is bringing this out around the period when new EU rules on replaceable batteries are expected to come into effect in early 2027 (though the rep tells me it's now 2028, but Sennheiser is still doing it). Whether that regulation was the full motivation or just part of it, the result is still good for buyers.

Design and comfort

The case is one of my favorite parts of the Momentum 5. It is better looking, better feeling, and less bulky than Sennheiser's older designs. More importantly, it is easier to fit into a pocket, which sounds mundane until you've lived with one of those older cases that feels like it was designed by somebody who has never worn pants.

For the earbuds themselves, I found the shell fairly small and quite comfortable. With the medium tips, I got a good seal and excellent general comfort. The included tip selection is useful too: extra small, small, medium, and large. I also like the understated look. These do not scream for attention.

There is some flexibility with third-party tips because the nozzle is circular rather than oval or rectangular. I was able to use Moondrop Pudding tips, although they did not solve my core seal inconsistency problem and I found them less comfortable than the stock tips.

Battery and repairability

This is the real differentiator. I think the user-replaceable battery setup is the best thing about the Momentum 5, not because it is flashy, but because it addresses the most predictable long-term failure point of true wireless earbuds. If you want to keep a device for years, battery wear is usually the thing that turns it into disposable electronics. Here, at least in principle, it does not have to.

That makes the Momentum 5 one of the first ANC true wireless earbuds in this lane that does not feel inherently temporary. In my view, that alone gives it a relevance most competitors simply do not have.

Noise cancelling and transparency

I found the noise cancelling to be a meaningful step up over earlier Sennheiser iterations. It is competitive with the Bose QC Ultra Gen 2, although not in exactly the same way. My impression was that Bose still had the edge for higher-frequency attenuation, but the Momentum 5 was impressively strong through the lows, low mids, and mids.

Transparency mode is also very good. In fact, I preferred it to the Bose QC Ultra Gen 2 in one specific and very practical respect: when I was speaking, my own voice sounded clearer. That matters for calls and for general situational awareness. I still would not put it at the level of what I hear from the AirPods Pro 3 for total transparency, but I came away impressed.

On microphones and call behavior more broadly, I had a good experience. The way my voice came through made the Momentum 5 feel especially usable for calls.

Outdoor usability

This is where my recommendation splits. When I walk outside with either ANC or transparency enabled, heavier footsteps can cause a crackling sound in my ears. My read is that vibration travels through my body, the seal becomes inconsistent, and that seal shift creates the crackling effect. It does not happen constantly, but when going downhill or walking with heavier impact, I found it rather annoying.

This seems fit-dependent. With the medium tips, I got the best seal, but also the crackling issue. When I switched to smaller tips, the issue mostly went away for me, but then I no longer got as good a seal, which means the noise cancelling performance suffers. That is an annoying tradeoff, and I don't love having to choose between stable outdoor behavior and better ANC.

It is also worth noting that I had a similar issue with the Momentum 4, while I did not have it with the Bose QC Ultra Gen 2, AirPods Pro 2, AirPods Pro 3, or Sony's recent models mentioned here. So I don't think this is just a generic true wireless problem. It seems more specific to how these Sennheiser tips and my ear canal interact.

Connectivity and features

You do get aptX lossless and adaptive support, along with a lossless mode option. With that said, I want to be blunt here because this gets overstated all the time: codec support is usually not what determines whether a wireless earbud sounds good. In most cases, codecs are already good enough. The much bigger variable is whether its frequency response agrees with your anatomy and preferences.

The app is also generally good and easy to use. You get Dolby Atmos, immersive audio with headtracking, a manual wind cut filter, and multipoint. I actually appreciate that the wind cut filter is manual rather than fully automatic because it lets me decide when I want it.

One of my favorite practical features is the ability to disable all touch controls. I hate touch controls on earbuds, and Sennheiser simply lets me turn them off. That is the kind of anti-nonsense option I wish more brands would include.

Sound quality

My overall take on the stock tuning is that it is mostly okay, and in this product segment, mostly okay already puts it ahead of a surprising amount of the field. The neutral preset has some forwardness around 200Hz, which gives it a slightly soupy or muddy character there. There is also a dip around 3kHz, though I personally do not mind that much because I tend to prefer a somewhat relaxed ear-gain presentation.

Treble is where my main complaint sits. I hear a spritzier, spicier rise starting around 7kHz, plus plenty of upper treble around 15kHz. Subjectively that can make the Momentum 5 a bit sibilant, and on percussion and cymbals there is some harshness. It is not disastrous, but it is not as smooth or natural as I would want.

Even so, I still think the stock sound is better than what I hear from the AirPods Pro 3 and Sony WF1000XM6 or XM5 by default. It is also competitive with the Bose QC Ultra Gen 2, just with a different voicing. The main advantage the Momentum 5 has over much of the competition is that the midrange comes through with more clarity. It is still a V-shaped tuning, make no mistake, but it is less cartoonishly store-demo V-shaped than a lot of mainstream ANC earbuds.

For my own anatomy, I still hear some lower-treble forwardness that gives certain sounds a slightly clacky, etched quality. But I would still call this one of the better stock tunings in this class.

EQ and app tuning

The app gives you a fixed-band EQ, and I think that is both good and frustrating. Good, because the filters are placed in sensible regions, including around 6kHz, 15kHz, 3kHz, 125Hz, and 325Hz. Frustrating, because there is no parametric EQ. At $299, I think that is a miss. Cheaper products have managed it, and I really do not buy the idea that premium brands cannot.

Still, the fixed-band EQ is useful. I was able to trim down some of that muddy upper-bass to low-mid energy and get a clearer presentation. For my taste, once adjusted, the Momentum 5 ended up sounding rather good, even better than the Bose QC Ultra Gen 2.

There is also a Sound Personalization feature. I find it genuinely interesting but I am not fully sold on it just yet. It works through a kind of psychoacoustic preference-based mapping process where you determine how you like certain instruments and elements of the mix to sound, and how you scale volume for these different elements relative to one another determines the sound. This doesn't just impact the frequency response, it also applies volume-dependent dynamic equalization that impacts loudness for different parts of the music. The result can end up sounding dramatically different from the default signature.

My issue is that this approach seems stimulus-dependent and signal-dependent. It may work very well for some music and less well for others. So while I think it has potential and is worth experimenting with, I still prefer direct, intentional EQ as a more versatile tool.

Verdict

I think the Sennheiser Momentum 5 TWS is a compelling premium earbud. It has strong ANC, very good transparency, good call behavior, a better-than-average stock tuning for this category, useful EQ, and the single most important long-term ownership feature in the segment: replaceable batteries.

If my primary use case were transit or general everyday listening while sitting still, I would take this over the Bose QC Ultra Gen 2, the Sony options mentioned here, and the AirPods. When you consider all of that, the overall package for the Momentum 5 is rather strong.

But my primary use case for these types of devices is walking outside and hiking, and for that, the vibration-related crackling issue is a real problem. So my verdict is simple. If that specific seal issue does not affect you, the Momentum 5 is one of the most sensible premium ANC earbuds you can buy right now. If you use earbuds the way I do, it is harder for me to recommend, because that one flaw gets in the way of an otherwise excellent idea.
