Sennheiser Momentum True Wireless 5: A Comfortable, Upgradable Earbud Experience

When I slipped the Sennheiser Momentum True Wireless 5 into my ears, the first thing that hit me was… well, a subtle smile. It’s not often that a new pair of earbuds manages to feel both familiar and fresh at the same time. Think of it like meeting an old friend who’s just come back from a good vacation – the same personality, but with a few new stories to share.

At $299.95, the MTW5 lives in the same price bracket as its predecessor, but Sennheiser decided to shave off a few grams and a lot of the boxy visual baggage. The buds now look like polished pebbles, each weighing a mere 7 g, and they come in five muted‑metal finishes – Denim, Cream, Copper, Graphite and Lavender. The rounded shape nests nicely in most ears, though folks with very small ear canals might still need a little extra wiggle room. I wore them for hours on a treadmill, through a crowded subway, and even while binge‑watching a series on the couch. The IP54 rating gave me confidence that the inevitable sweat didn’t turn into a soggy mess.

Inside each earbud lives a tiny tech zoo: three microphones, one bone‑conduction accelerometer and a second‑generation Snapdragon Sound processor. Together they drive the adaptive ANC (which is solid, if not world‑shattering), a transparent mode that lets you hear the world without pulling the buds out, and a call system that is, well, functional. I’m not a fan of making phone calls from earbuds, so I barely used that feature, but it works when needed.

Perhaps the most conversation‑worthy change is the replaceable‑battery concept. Both the earbuds and the charging case have tiny Phillips‑head screws that let you swap out the cells when they start to lose juice. The spec sheet claims 12 hours of playback without ANC and six hours with it turned on, plus up to 40 hours from the case. In practice, the numbers feel about right, and the ability to replace the cells means you aren’t forced to toss the whole set when the battery ages. It’s a small eco‑gesture that feels surprisingly forward‑thinking.

Sound‑wise, the MTW5 lands a bit on the warm side straight out of the box – a gentle boom in the low‑mids that reminds me of the larger Momentum 5 headphones that cost $400. The 7 mm TrueResponse driver, manufactured in Sennheiser’s Irish facility, delivers clarity that holds up well across everything from Elton John’s piano‑driven ballads to the gritty basslines of New Order. Vocals sit right up front, instruments stay distinct, and the overall presentation feels balanced, not overly bright.

If you like to tinker, the SmartControl+ app opens up an 8‑band graphic EQ, a handful of preset personalities and a “Sound Personalization” wizard that tailors the response to your ear shape. The sliders aren’t as surgical as a parametric EQ you’d find on a $500 headphone, but they’re more than enough to nudge the bass tighter, pull back a harsh treble, or add a little sparkle to the mids. After a quick tweak, the earbuds move from a pleasant consumer sound to something that sits comfortably next to true‑audiophile gear like the IE 900 in‑ear monitors.

Connectivity gets a bump too. Bluetooth 6.0, a Snapdragon Sound 5 Gen 3 chip and support for aptX Adaptive and aptX Lossless mean you can push 24‑bit/96 kHz streams when you pair the buds with a compatible source, such as Sennheiser’s BTD 700 adapter. The soundstage opens up a notch, and the detail retrieval feels noticeably richer. Of course, the wireless link can hiccup in RF‑crowded places – a reality for any modern Bluetooth device – but the ability to switch between a standard iPhone connection and a higher‑resolution codec on a laptop is a welcome flexibility.

There’s also an Immersive Mode that uses head‑tracking to keep audio cues anchored to the screen, making movies feel a little more cinematic. It’s a gimmick that works better in some titles than others, but it’s another proof that Sennheiser is trying to give users more than just “play‑music‑and‑go.”

All things considered, the Momentum True Wireless 5 is a solid evolution rather than a revolution. It feels lighter, looks sleeker, lets you replace the batteries, and offers a tunable sound that can satisfy both casual listeners and audiophiles who like to fine‑tune their audio. If you’re already on the fence about true‑wireless earbuds, the MTW5 gives you a good reason to jump in – and to stay for the long haul.
