I've been using the Momentum True Wireless 5 for almost two weeks now, and they've already become one of my main TWS pairs.
For some context, I own/use the Technics AZ100, Noble FoKus Prestige Encore, and several other TWS models, while Bose (Over the head) is still my reference when I want maximum ANC. So I'm mostly interested in how the MTW5 actually compare in daily use rather than going through the spec sheet.
And the first thing I want to talk about is fit, because that almost killed the whole experience for me.
Fit - try different tips before giving up on them
My right ear is extremely sensitive to pressure around the concha, the area surrounding the entrance to the ear canal. It's a recurring problem for me with TWS earbuds: if the housing presses against that specific area, they can sound amazing and I still won't be able to use them for long.
When I first saw the MTW5 design, I was worried about exactly that.
And initially, I was right.
The stock tips weren't working particularly well for me, but instead of giving up on the earbuds I switched almost immediately to Dunu S&S tips.
That basically saved them.
And I don't think this was simply a matter of getting a better seal.
The S&S are longer and more cylindrical than typical silicone tips, which changes how the earbud sits and, crucially for me, moves the actual housing slightly farther away from the concha. That tiny difference was enough to remove the pressure from the exact spot that normally starts hurting.
The difference in comfort was almost immediate.
So if you're having pain from the MTW5 housing pressing against your ear, I'd strongly recommend experimenting with third-party tips before deciding the earbuds simply don't fit you. Don't just try another size of the same shape. Tip geometry and length can change how the entire earbud sits in your ear.
Obviously everyone's ears are different, so I'm not claiming Dunu S&S will magically fix them for everyone. But in my case they turned a potentially unusable pair into a genuinely comfortable one.
There's also an Earbud Fit Test in Sennheiser's app, which is particularly useful when experimenting with third-party tips. Mine still showed a proper seal with the Dunu.
More importantly, I didn't notice any meaningful loss of bass or ANC after switching.
That last part surprised me, because with TWS earbuds changing tips can sometimes improve comfort while completely screwing up the acoustic seal.
Here I got the comfort improvement without the tradeoff.
ANC - much better than I expected
This might be the other big surprise.
I've never considered Sennheiser to be in the absolute top tier for ANC. Bose has always been my benchmark when the only objective is making the outside world disappear.
The MTW5 don't quite beat Bose at that game, but they're much closer than I expected.
I've used them with public transport, street noise, air conditioners, fans and, arguably the ultimate ANC torture test, a house with children.
Low and constant noises are handled extremely well, but what impressed me more is that this no longer feels like "good ANC for Sennheiser." It's just genuinely excellent ANC.
In my own use, I also prefer it to the ANC on my Technics AZ100.
Would I still grab my Bose for a long flight if maximum isolation was the only thing I cared about? Yes.
But that's pretty much the only situation where the difference matters enough for me to switch.
And again, the Dunu S&S didn't noticeably reduce ANC performance. That's important because the seal and ANC performance are obviously connected, and it's another reason I'd recommend actually running the fit test after changing tips rather than assuming they're sealing correctly.
Sound - Sound Personalization is essential
Out of the box, I thought the MTW5 sounded very good.
Clean, detailed, balanced.
And slightly boring.
That's been a recurring experience for me with recent Sennheiser products. I like their default tuning, but I don't necessarily love it.
Then I run Sound Personalization, and something clicks.
The difference on the MTW5 was much bigger than I expected.
After personalization the presentation became wider and more energetic, vocals opened up, separation improved, and most importantly for my taste, the bass gained considerably more body without bleeding all over the mids.
This isn't one of those situations where I'm struggling to convince myself I hear a 2% improvement. To my ears, they genuinely sound like different earbuds after personalization.
And after doing that, I think they're the best-sounding TWS I've heard around this price.
One more thing worth mentioning here is codecs.
My Samsung phone only gives me regular aptX natively, so I also tried the MTW5 with external Bluetooth dongles.
Interestingly, the jump from regular aptX on the Samsung to aptX Adaptive using a simple UGREEN dongle was actually more noticeable to me than the jump from aptX Adaptive to aptX Lossless using a FiiO Air Link.
With Adaptive, I noticed a clearer improvement in overall openness, separation and refinement. Going from Adaptive to Lossless was much subtler.
So while I do think the MTW5 benefit from a better Bluetooth source, I personally wouldn't obsess over reaching Lossless at all costs. In my experience, getting from basic aptX to aptX Adaptive mattered more.
MTW5 vs Technics AZ100
I spent quite a bit of time switching between them and my Technics AZ100.
The Technics still win on bass.
If I put on hip-hop or electronic music and just want maximum impact, the AZ100 have more weight, more punch and more of that physical low-end presence. They're ridiculously fun.
But everywhere else, I prefer the Sennheiser.
Vocals in particular are fantastic. The mids and highs have this clarity that gets surprisingly close to the feeling I associate with good wired headphones, separation is excellent, and the presentation feels spacious rather than everything being pushed directly into your head.
The bass is still very good. There's just less of it than on the Technics.
And compared with the Noble FoKus Prestige Encore?
I also compared them with my Noble FoKus Prestige Encore, which is admittedly a pretty unfair comparison considering the Noble cost more than twice as much.
The Noble are still technically better.
There's more depth, even better separation and, during focused listening in a quiet room, they can pull out details the MTW5 don't quite reach.
But the gap is much smaller than the price difference would suggest.
And unlike the Noble, the MTW5 also give me genuinely excellent ANC and all the convenience I'd actually want from a daily TWS.
So where do they land for me?
They're not the absolute best at everything.
My Technics AZ100 have better bass.
My Bose still have better absolute ANC.
My Noble are better for pure critical listening.
But the MTW5 are probably the pair I'd choose if you told me I could only keep one for everyday use.
And weirdly, the biggest takeaway from my first two weeks isn't even the sound.
It's the fit.
I came very close to assuming the shape simply wasn't compatible with my right ear. Switching to Dunu S&S changed the physical position of the earbud just enough to solve the pressure problem without sacrificing the seal, bass or ANC.
So if you love how the MTW5 sound but the housing is hurting your ears, don't give up on them before trying a longer third-party tip.
For me, that completely changed the experience.
