Snapshot
The 30-Second Version
The Momentum 4 Wireless delivers elite, best-in-class sound and ANC that rival wired setups. It's heavy and the comfort lags behind, and the price floor has risen, but it's still a steal under $200. Worth it for audio purists who don't mind a tight fit.

The proof
Performance
The 42mm drivers deliver audio that sits in the 98th percentile—this is reference-level clarity with deep, controlled bass that doesn't muddy the mids. ANC is equally top-tier, easily hushing a busy train or open office. Battery life hits a real 60 hours with ANC on, and a quick 5-minute top-up buys you 4 hours. Connectivity is flawless with aptX Adaptive and rock-solid multipoint. The four-mic array punches above its weight for calls, though the 13th percentile comfort score stings: after an hour, many will feel the clamp. Build is solid but plasticky, lacking the premium feel of rivals.

vs Competition
Stacked against the Sony WH-1000XM6, the Momentum 4 wins on raw detail and battery stamina, but Sony's lighter build and slightly more polished ANC keep it ahead for all-day wear. The Bose QuietComfort Ultra is way comfier, though its sound signature lacks the Sennheiser's depth and sparkle. Bowers & Wilkins Px8 S2 brings a similar audiophile flavor but costs more and taps out earlier. New challengers like the Sony ULT WEAR and TOZO HT3 offer solid alternatives at lower prices, but they can't match the Momentum 4's sheer audio fidelity. Easy pick: if sound is your North Star, the Sennheiser leads the pack.

Price
Value & Pricing
At full MSRP, $300 feels steep. The floor has crept up to $181, so the days of snagging these for $151 are gone. Still, at under $200, you're getting elite sound and ANC for less than many mid-range pairs. Even around $220, it's a bargain if you can live with the comfort trade-offs. Shop around and avoid paying list price.

Overview
Sennheiser's Momentum 4 Wireless ditches the retro vibe for a sleek, fold-flat design that packs a massive 60-hour battery. The sound is undeniably Sennheiser: rich, detailed, and backed by aptX Adaptive for high-res streaming. But there's a catch—comfort lands at just the 13th percentile in our database. At 454g with noticeable clamping force, these aren't the headphones you'll forget you're wearing.
If you can look past the heft, you're getting some of the best audio and noise cancellation on the market. The adaptive ANC is among the elite, calls are crisp, and Bluetooth multipoint works without a hitch. It's a powerhouse for commuters and sound nerds alike, as long as your ears can handle the fit.
Common Questions
Q: What size are the headphone drivers?
They use 42mm dynamic drivers, the same as the previous Momentum model but tuned for a wider 6Hz–22kHz range.
Q: How long does the battery really last?
Up to 60 hours with ANC on, and a 5-minute charge gives you 4 hours of playback—plenty for most commutes and flights.
Q: What is the length of the detachable cord?
The included 3.5mm cable is about 1.2 meters long, handy for wired listening when the battery dies or you want zero latency.
Who Should Skip This
Skip these if all-day comfort is non-negotiable—the weight and clamp will likely grate on you. If you need neutral, studio-accurate monitoring, the Momentum 4's 75.2 studio score means it's not the flattest tool in the shed. For sheer featherweight wearability, go with the Bose QuietComfort Ultra instead.
Verdict
Get these if you want the best-sounding wireless headphones under $300, even with the higher entry price. Commuters and office warriors will love the noise cancellation, and call quality is more than solid. Just try them on first: if the weight or clamp bothers you, you'll regret it.
