Sennheiser Momentum True Wireless 5: Audiophile‑grade Earbuds That Feel Right at Home

When I slipped the new Sennheiser Momentum True Wireless 5 (MTW5) into my ears, the first thing I heard was a tiny bit of Elton John – “Blue Jean Baby, L.A. Lady” – playing like a whisper around my skull. I’m a 50‑something writer, so I’ve kinda made it a ritual to test any new audio gear with a classic tune. Today, though, I wasn’t just hearing a song; I was hearing the whole package click into place.

Let’s start with the look. The old Momentum 4 buds were a little… boxy, with silicone wing‑tips that felt more like a headset than an earbud. The MTW5 drops that clunky silhouette for a sleek, pebble‑shaped design that actually looks good on a coffee table. They weigh about 7 grams each and come in five metallic finishes – Denim, Cream, Copper, Graphite and Lavender – so you can pick a color that matches your jacket, or your mood, whatever. I have fairly average‑sized ears, and the buds sat snugly for hours, whether I was lounging on the couch or sprinting on a treadmill. Smaller‑ear folks might have a different experience, but the IP54 rating gave me confidence that sweat and a bit of rain won’t kill them.

What really makes the MTW5 feel like a step forward is the replaceable‑battery concept. Both the earbuds and the charging case use tiny, user‑serviceable cells. Yes, you need a small Phillips screwdriver and a plastic wedge, but it’s doable. When the battery finally starts to sag – which it will, as with any rechargeable device – you can swap it out instead of tossing the whole thing. It feels oddly satisfying, like fixing a tiny piece of tech you actually want to keep around.

On the tech side, each earbud houses six microphones and two bone‑conduction accelerometers. That combo powers adaptive ANC, a Transparency mode that lets you hear the world when you need to, and decent call quality (I still avoid using earbuds for calls, but they work). The touch controls are straightforward, and you can turn them off if you prefer handling everything through the SmartControl+ app.

Sound‑wise, the MTW5 is an interesting beast. Out of the box the tuning leans a touch toward a warm, bass‑friendly profile – not as boomy as a cheap true‑wireless, but definitely more forgiving than a clinical audiophile reference. The 7 mm TrueResponse driver, built in Sennheiser’s Irish factory, delivers clear mids and punchy lows without turning the mids into a mushy swamp. Vocals sit on top, instruments stay separate, and there’s enough detail to enjoy a podcast as much as a synth‑laden track.

If you’re the type who likes to tweak, the app offers an 8‑band graphic EQ, a handful of presets and a “Sound Personalization” wizard. It isn’t a parametric EQ with infinite finesse, but you can still pull down a little excess bass, boost the high‑mids, or shape the treble to taste. After a few adjustments, the sound moves closer to Sennheiser’s flagship IE 900 IEMs – a nice blend of flesh and refinement.

Connectivity is another area where the MTW5 shines. It supports Bluetooth 6.0 with SBC, AAC and a Snapdragon Sound Series 5 Gen 3 chip that unlocks aptX Adaptive and even aptX Lossless when paired with a compatible transmitter. In a quiet room the extra bandwidth translates to more depth and definition; in a crowded cafe, you might notice occasional stutters due to RF congestion, but it’s still generally reliable.

The active noise cancellation is solid, though not industry‑leading. It does enough to hush the gym treadmill or the hum of an airplane cabin, and the Immersive Mode with head‑tracking adds a bit of spatial flair for gaming or movies. When you need to hear the world, the Transparency mode lifts voices and ambient sounds cleanly, without the “hissy” quality some competitors suffer.

Overall, the MTW5 feels like a genuinely usable, future‑proof true‑wireless set. It’s not a luxury headphone replacement, but for $299 it offers audiophile‑grade drivers, decent ANC, a handy EQ app and – most importantly – a path to keep them alive longer through replaceable batteries. If you value sound quality and want a pair of earbuds that won’t become electronic trash in a year or two, these are worth a serious look.
