Sennheiser Momentum True Wireless 4 Review: Worth Buying?

Great sounding earbuds are easy to find in 2026. Great sounding earbuds that also handle noise, calls, apps, and future Bluetooth standards are much rarer.

The Sennheiser Momentum True Wireless 4 tries to be that rare set. It carries a premium price, a 7mm TrueResponse driver, and a feature list that reads like a wish list for audio nerds.

I spent weeks with these buds on trains, at desks, in gyms, and on flights. This review covers what they get right, where they slip, and who should actually buy them.

In a Nutshell

Here is the short version for readers who want the verdict fast.

• Sound quality is the headline feature. The 7mm TrueResponse driver delivers deep bass, clean mids, and detailed treble. Independent lab scoring from HEAD acoustics gave these buds an excellent timbre score of 4.9 out of 5, which is close to the top of the category.
• Noise cancellation is strong but not class leading. Lab testing measured roughly 83% average noise attenuation. Bose still wins the silence contest, yet these buds block enough engine drone and office chatter for daily use.
• Battery life beats most rivals. Testing showed 7 hours and 45 minutes on a single charge at normal volume, plus around 30 hours total with the case. Qi wireless charging and an 8 minute quick charge are included.
• Connectivity is future proof. You get Bluetooth 5.4, aptX Adaptive, aptX Lossless, LE Audio with LC3, Auracast, and multipoint pairing. Android owners gain the most here.
• The microphone is the weak spot. Voice pickup is fine indoors but struggles in wind and busy streets. Heavy call users should look elsewhere.
• Price has softened since launch. These launched near $300 and now sell lower during sales, which changes the value story a lot.

Sennheiser Momentum True Wireless 4 Overview

Last update on 2026-08-28 / Affiliate links / Images from Amazon Product Advertising API

The Momentum True Wireless 4 sits at the top of the Sennheiser earbud lineup. Sennheiser built it to fight the Sony WF-1000XM5, the Bose QuietComfort Ultra Earbuds, and the Technics EAH-AZ80.

Sennheiser has a long audio history. That history shows in the tuning choices here, which favor musicality over gimmicks.

The buds use a single 7mm TrueResponse transducer per side. This is the same driver family Sennheiser has refined across four generations of Momentum earbuds.

Adaptive noise cancellation runs on a hybrid mic array. The system reads your surroundings and adjusts filtering strength on the fly.

The charging case is small, fabric wrapped, and pocket friendly. It supports Qi wireless charging, which the previous generation lacked.

Sennheiser also loaded this model with software features. Sound Personalization, Sound Check, a 5 band equalizer, Sound Zones, and a fit test all live inside the Smart Control app.

The buds carry an IP54 rating. That covers sweat, dust, and light rain, though it will not survive a swim.

Colors include black copper, graphite, white silver, and metallic silver. The metallic ring around each bud gives them a jewelry look that stands out from black plastic rivals.

The core promise is simple. Sennheiser wants you to buy these for sound first and treat the smart features as a bonus.

Design, Build Quality and What Is in the Box

The Momentum True Wireless 4 looks expensive. Each bud has a flat outer face with a polished metal ring, and the finish resists fingerprints better than glossy plastic.

The buds are larger than AirPods Pro. They stick out from the ear a little, so people with very small ears should check the fit carefully.

Build feels solid. The plastic does not creak, the case hinge snaps shut with confidence, and the magnets hold the buds firmly.

The case deserves a mention. It uses a soft fabric wrap that feels warmer in the hand than the slick plastic used by most brands.

One odd choice sits on the front. The USB C port faces forward instead of sitting on the back, which looks unusual but works fine.

Inside the box you get the earbuds, the charging case, a short USB C cable, four sizes of silicone ear tips, and three sizes of concha fins.

Those concha fins matter more than people expect. They lock the bud into the outer bowl of your ear and stop the buds from rotating during movement.

The documentation is brief. Sennheiser expects you to use the app, and honestly you should.

At around 6 grams per bud, the weight sits in normal territory. The size is the bigger factor for comfort, not the mass.

Overall the design reads as grown up rather than sporty. These look at home in an office or on a plane, less so in a boxing gym.

Comfort and Fit for Long Listening Sessions

Fit decides everything with these buds. Sound quality, bass response, and noise cancellation all collapse if the seal is poor.

I started with the medium tips and medium fins. That combination worked for about two hours before the outer edge started to press.

Switching to a smaller fin fixed the pressure completely. After that change I wore them for a full workday with only short breaks.

Run the fit test in the Smart Control app before you judge these earbuds. It plays a tone, measures the seal, and tells you if each side passes.

The nozzle is circular and fairly shallow. You do not need to push these deep into the canal, which suits people who dislike the plugged feeling of deep insertion buds.

Ears with narrow canals may still struggle. The circular nozzle shape fits some ear anatomies less naturally than an oval nozzle.

For workouts the IP54 rating and the fins hold up well. I ran 5 kilometers with no slippage, though heavy sweat sessions may need a wipe down afterward.

Long flights are where these shine. The light clamping force and shallow fit avoid the ear fatigue that deeper buds cause after four or five hours.

Glasses wearers face no issues since nothing touches the temple arm. Sleepers should skip these because the buds sit too proud of the ear.

Sound Quality Across Music Genres

This is the reason to buy the Momentum True Wireless 4. The tuning is warm, wide, and detailed in a way that few wireless buds match.

Bass arrives with weight and control. Kick drums land with a firm punch instead of a loose thud, and sub bass extends low without smearing the mids.

Vocals sit forward and natural. Female vocals in particular carry texture and breath, which many bass heavy rivals flatten.

Treble is bright without being harsh. Cymbals shimmer, string plucks sparkle, and long listening sessions do not cause fatigue.

The soundstage is the real surprise. Instruments spread wider than the earbud form factor suggests, and stereo imaging places each element clearly.

Independent testing supports my impressions. The HEAD acoustics MDAQS panel scored these buds 4.9 for timbre, 4.4 for immersiveness, and 4.8 overall.

Rock and metal benefit from the clean separation. Layered guitars stay distinct instead of blending into a wall of noise.

Electronic music is a highlight. The bass boost preset adds a few decibels below 300Hz, which turns club tracks physical without muddying vocals.

Jazz and acoustic recordings sound honest. Upright bass has body, brushes on snare have grain, and piano notes decay naturally.

The 5 band equalizer gives you real control. Small adjustments go a long way here because the default tuning is already balanced.

One caveat applies. Bass lovers who want a boomy signature out of the box may find the default tuning too polite before EQ.

Top 3 Alternatives for Sennheiser Momentum True Wireless 4

Not everyone needs audiophile tuning. These three sets solve different problems at similar prices.

The Sony WF-1000XM5 is the all rounder. It offers stronger noise cancellation, a smaller body, better call quality, and around 8 hours of battery life.

Sony also wins on app features for casual users. Speak to Chat, adaptive sound control, and 360 Reality Audio add convenience that Sennheiser skips.

The Bose QuietComfort Ultra Earbuds is the silence king. If you fly weekly or work in an open office, this is the set that removes the most noise.

Bose Immersive Audio also creates a convincing out of head effect. Battery life is shorter at roughly 6 hours, and the buds are chunky.

No products found.

The Technics EAH-AZ80 is the connectivity champion. It pairs with three devices at once, which no rival matches, and the 10mm driver delivers rich sound.

Technics also nails comfort with a small housing and a wide tip selection. Call quality is excellent, making it a smart pick for remote workers.

Pick Sony for balance, Bose for silence, and Technics for multipoint and calls. Pick the Sennheiser if pure sound quality and codec support top your list.

Active Noise Cancellation Performance

The adaptive ANC here is good rather than legendary. Lab measurements landed around 83% average noise attenuation, which places these in the upper tier without topping it.

Low frequency rumble disappears well. Plane engines, bus drone, train rattle, and air conditioning fade into the background quickly.

Mid frequency noise gets softened but not erased. Nearby conversation drops to a murmur, and you can still tell someone is speaking.

Sudden sharp sounds still get through. Doors slamming, keyboard clacks, and train announcements cut past the filtering more than they do on Bose buds.

Passive isolation carries a lot of the load. With a correct seal, the physical blocking alone reaches nearly 50dB in some ranges.

The adaptive mode adjusts strength automatically. On quiet streets it eases off, and in loud stations it ramps up without any pumping or hiss.

You can also set fixed ANC levels in the app. I preferred maximum ANC on flights and a lower setting while walking.

Sound Zones is a clever addition. You can save GPS locations and assign ANC settings to them, so your office triggers full cancellation automatically.

No pressure sensation appears at high ANC levels. Some people feel a vacuum effect with aggressive cancellation, and Sennheiser tuned that out well here.

For most buyers this ANC is plenty. Only frequent flyers chasing absolute silence need to consider Bose instead.

Transparency Mode and Awareness

Transparency mode on these buds is genuinely useful. Voices sound natural, and the processing avoids the hollow tunnel effect that cheaper buds produce.

You can adjust the passthrough level in the app. I left it at default because that setting sounded closest to open ears.

Ordering coffee works without removing a bud. The barista sounds present rather than piped in through a speaker.

Traffic awareness is solid. Cars, bikes, and footsteps register with enough directional information to keep you safe on sidewalks.

Wind does create some rustle in transparency mode. Turning the level down reduces the effect but does not remove it entirely.

A single tap on the left bud toggles transparency. That shortcut is fast enough to use mid conversation without fumbling.

Music keeps playing during transparency by default. You can also lower media volume automatically so speech cuts through more clearly.

Anti Wind mode helps outdoors. It trades a little cancellation strength for far less buffeting noise.

Compared to Apple and Bose, Sennheiser sits just behind on pure naturalness. The gap is small and most listeners will never notice it.

The practical result is fewer bud removals per day. That alone makes the feature worth learning.

Battery Life and Charging Options

Battery performance is a clear win. Real world testing produced 7 hours and 45 minutes of playback at a safe listening volume.

Sennheiser rates the buds at 7.5 hours with ANC off and around 7 hours with ANC on. My results matched those claims closely at moderate volume.

Loud volume changes the math. Pushing past 80% volume with full ANC brought me closer to 5 hours per charge.

The case adds roughly three extra charges. Total runtime lands near 30 hours, which covers a full week of commuting for most people.

Fast charging works well. Eight minutes in the case delivers about an hour of listening, which saves you during rushed mornings.

Qi wireless charging is included this generation. Dropping the case on a pad at the desk removes cable clutter entirely.

Battery Protect Mode is the smart addition. It charges slower and stops short of a full charge, which extends long term cell health.

That feature matters more than it sounds. Earbud batteries degrade fastest when they sit at 100% constantly, and this mode prevents that.

The app shows separate percentages for each bud and the case. Voice prompts also announce battery level when you insert the buds.

Compared to rivals, only Sony matches this endurance. Bose falls well short at around 6 hours.

Bluetooth 5.4, Codecs and Auracast Support

Connectivity is the most future proof part of this package. Bluetooth 5.4 handles the link, and the codec list is the longest in the category.

Supported codecs include SBC, AAC, aptX Adaptive, aptX Lossless, and LC3. That covers every phone type sold today.

Android users with Snapdragon Sound phones gain the most. aptX Lossless delivers CD quality audio over Bluetooth when the source device supports it.

iPhone users are limited to AAC. Apple implements AAC well, so the buds still sound great, but the lossless advantage disappears.

LE Audio support arrived through a firmware update. LC3 improves efficiency, which means better quality at lower bitrates and less battery drain.

Auracast is the forward looking feature. It lets you tune into public broadcast audio at airports, gyms, cinemas, and lecture halls.

Auracast adoption is still growing in 2026. Venues are rolling it out slowly, so treat this as insurance rather than a daily benefit.

Multipoint pairing connects two devices at once. Switching between a laptop call and a phone call worked reliably in my testing.

Connection stability was excellent. I walked through a crowded station with zero dropouts, which is not always true of premium buds.

One limitation exists. The case cannot act as a Bluetooth transmitter, so airplane entertainment systems still need a separate dongle.

Smart Control App and Sound Personalization

The Sennheiser Smart Control app is one of the better companion apps available. It loads fast, avoids clutter, and hides advanced tools without burying them.

The 5 band equalizer sits front and center. Presets include Bass Boost, Podcast, and several genre options, and you can save custom curves.

Sound Personalization is the standout tool. It plays test tones and builds a hearing profile, then adjusts output to match your ears.

Sound Check works differently. It presents pairs of sound profiles and asks you to pick a favorite, then blends the results into a custom tuning.

The fit test takes 15 seconds. It reports pass or fail for each ear and suggests trying a different tip size when the seal is weak.

Sound Zones use GPS to trigger settings. Your gym can load bass boost with transparency while your office loads full ANC with a flat profile.

Firmware updates arrive through the app. Sennheiser has pushed several meaningful updates since launch, including the LE Audio rollout.

Control customization lets you reassign every tap gesture. You can also disable gestures you trigger by accident.

The app does request an account for some features. Data collection warnings appear during Sound Check, though the processing is standard for this type of tool.

Nothing here feels like filler. Every tool has a clear purpose, which is rare in earbud software.

Touch Controls and Daily Handling

The buds use capacitive touch plates on the flat outer face. Touch controls avoid pushing the bud deeper into your ear, which protects the seal.

Default gestures are logical. A single tap on the right plays or pauses, and a single tap on the left toggles transparency.

Double tap skips tracks forward on the right and backward on the left. Triple tap cycles ANC on the left and calls the voice assistant on the right.

Long press controls volume. Left lowers it and right raises it, with steady steps rather than jumps.

Response time is quick. I rarely had a tap ignored, and false triggers while adjusting the buds were uncommon.

Wear detection pauses music when you remove a bud. It resumes within a second when you put the bud back.

The touch surface is large enough to hit reliably. Gloves reduce accuracy in winter, which is a common limitation for capacitive panels.

Voice assistant access works with Google Assistant, Siri, and Alexa. Response speed depends on your phone rather than the buds.

Pairing is simple through Fast Pair on Android. iPhone owners pair manually in about 20 seconds.

Daily handling is smooth overall. The case opens one handed, the buds seat magnetically, and nothing about the routine feels awkward.

Call Quality and Microphone Performance

This is the weakest area. Sennheiser tuned these buds for listening, and the microphone system shows it.

In quiet rooms your voice sounds clear enough. Callers reported normal clarity with a slightly thin tone.

Office noise causes problems. The system attenuates constant background sound but lets sudden noises through at full volume.

Street calls suffer more. Traffic and passing conversation bleed into the pickup, and your voice loses body against that background.

Wind is the biggest failure. Even light breeze creates buffeting that badly damages speech intelligibility.

Compare that to Technics or Sony and the gap is obvious. Both rivals suppress background noise far more consistently.

Sidetone is available in the app. Hearing your own voice helps you avoid shouting, and I recommend enabling it.

Video calls at a desk work fine. Zoom and Teams sessions from a home office produced no complaints from colleagues.

Bluetooth call latency was low. No echo or delay appeared during any of my test calls.

Judge these buds accordingly. If half your day involves outdoor calls, this is a real reason to choose a different model.

Price, Value and Who Should Buy the Momentum True Wireless 4

No products found.

These launched at around $299.95. Street prices have dropped meaningfully since then, and sale pricing often lands well below the original figure.

At full price the value argument is tight. At sale prices the value becomes strong, because nothing else at that level sounds this good.

Buy these if sound quality is your top priority. Audiophiles, genre hoppers, and anyone stepping up from budget buds will hear the difference immediately.

Buy these if you own a modern Android phone. aptX Lossless, LE Audio, and Auracast only pay off with the right source device.

Buy these if you want long battery life. Nearly 8 hours per charge removes daily charging anxiety.

Skip these if calls dominate your day. The microphone is the one component that does not match the price tag.

Skip these if you need maximum silence. Bose still owns that title by a clear margin.

Skip these if you have very small ears. The housing size and circular nozzle do not suit everyone.

iPhone users sit in the middle. The buds still sound excellent through AAC, but you leave the headline codec features unused.

Check the current price before deciding. These buds move between good value and premium value depending on the deal available.

Pros and Cons Summary

Here is the balanced view after weeks of testing.

The strengths are easy to list. Sound quality leads the category with warm bass, natural vocals, and a soundstage that feels wider than the hardware suggests.

Battery life at nearly 8 hours beats most premium rivals. The case adds roughly three more charges and supports both wireless and fast charging.

Codec support is unmatched. aptX Lossless, LC3, LE Audio, and Auracast give these buds a longer useful life than most competitors.

The Smart Control app is genuinely helpful. Sound Personalization, Sound Zones, and the fit test add real value rather than novelty.

Build quality and materials feel premium. The metal accents and fabric case justify the price visually.

The weaknesses are equally clear. Microphone performance disappoints in wind and street noise, which limits mobile call use.

Noise cancellation trails Bose. It handles low frequency drone well but lets sharp sounds through.

The buds are large. Small ears may struggle even with three fin sizes available.

The case cannot transmit audio. Airplane use still requires an extra adapter.

Full retail pricing is steep. Waiting for a sale changes the value equation completely.

Final Verdict on the Sennheiser Momentum True Wireless 4

The Momentum True Wireless 4 earns a strong recommendation with one clear condition. Buy these for how they sound, not for how they handle calls.

Sennheiser built a set of earbuds that treats music seriously. The tuning rewards good recordings and makes familiar albums feel new again.

The supporting features hold up well. Battery life is excellent, the app is useful, and the connectivity list is the most future proof in the category.

Noise cancellation is good enough for commutes, flights, and offices. It just is not the best available, and honest buyers should know that going in.

The microphone remains the one genuine flaw. Sennheiser has improved it through firmware, though it still trails Sony, Bose, and Technics.

Score wise I would place these around 8.7 out of 10. Sound quality pushes the number up, and call performance pulls it down.

Anyone upgrading from midrange earbuds will hear an immediate leap in clarity and bass control. That upgrade feeling lasts well past the first week.

Android owners with modern phones get the most complete experience. iPhone owners still get a great sounding set of buds with fewer bonus features.

These are the best sounding mainstream true wireless earbuds you can buy right now. If that sentence matters to you, the decision is simple.
