Compare Audio-Technica ATH-CKS50TW Earbuds vs Sennheiser Momentum True Wireless 4 Earbuds

ANC performance was the most divided feature: some reviewers found it strong or effective, while several called it average, mediocre, or disappointing versus leaders.

Reviewers generally find ANC good to very good, strong for commute noise, though several say Sony or Bose can still block more.

Android pairing was praised through Google Fast Pair and straightforward setup on Android devices.

Android compatibility is praised where Snapdragon/lossless support and Android EQ options matter, with no Android issues in one test.

The Connect app was broadly praised as thorough, useful, and feature-rich, with repeated appreciation for customization, updates, and extra controls.

The Smart Control app is widely praised for useful features, fit tests, EQ, battery options, and customization, though one review found it somewhat overwhelming.

aptX support was treated as a positive for higher-quality or potentially better fidelity, especially for compatible devices.

aptX support is valued for Android users, but one reviewer found the aptX lineup confusing and hard to distinguish in practice.

Low-latency performance and video sync were a clear strength, with reviewers repeatedly reporting little to no perceptible delay.

Latency is usually acceptable for video, calls, and casual gaming, though one review warns competitive shooters may still be less ideal.

Auracast is viewed as meaningful future-proofing, even if its current usefulness depends on wider adoption.

Bass was a major strength for most reviewers, described as deep, warm, thumpy, or great, but a few noted it could obscure mids or lacked flagship-level cleanliness.

Bass is a major strength: reviewers describe it as deep, controlled, punchy, warm, and rarely overpowering.

Battery life was the clearest consensus strength, with reviewers repeatedly calling it epic, insane, best-in-class, or unusually long.

Battery life is generally competitive and often praised, but some reviewers note it is not class-leading or may be short for some listeners.

Bluetooth performance was generally stable and reliable, with strong connection praise, though one reviewer reported random signal drops in some multipoint use.

Bluetooth and wireless connectivity receive strong praise from most reviewers, with a few caveats around iPhone issues or high-codec stability.

Build quality was mostly viewed positively, with reviewers praising sturdy construction or non-cheap materials, though one reviewer criticized the build as not amazing.

Build quality is consistently considered premium, durable, and well finished.

Hi-res capability is discussed through lossless/high-resolution Bluetooth playback rather than a separate DAC, with enthusiasm tempered by device requirements.

Button usability split reviewers sharply: some preferred responsive physical buttons, while others found them fiddly, hard to locate, or awkward to press.

Case quality was generally positive for sturdiness, magnets, finish, or design, although size hurt portability rather than perceived construction.

The fabric-wrapped case is widely liked for feel and build, despite repeated complaints that it is bulky.

Charging was mixed: fast charging drew strong praise, but multiple reviewers criticized the lack of wireless charging on the original model.

Charging is praised for wireless charging, fast top-ups, and battery-protection options.

Codec support was praised as a strong spec highlight, especially around Bluetooth 5.2 and aptX Adaptive.

Codec support is treated as a premium strength, especially on Android, though benefits depend on compatible devices and settings.

Comfort was mostly positive despite the bulky housings, with several reviewers wearing them for long periods, though one TW2 review found the design less comfortable.

Comfort is mostly positive for long sessions, but some reviewers found size, wings, or weight limiting after hours.

Design impressions were mixed to negative: some liked the subdued look, but many called the buds or case bulky, plain, or not especially attractive.

Design is seen as stylish and premium, although several reviewers note it changes little from the previous generation.

Fit was generally secure and comfortable for some reviewers, but fit concerns remained for smaller ears or wind-noise isolation.

Fit evidence is mixed: many reviewers get a secure seal, while small ears or thin tips caused problems for others.

One review praised the four tip sizes as giving plenty of range to find a comfortable fit.

Ear-tip and fin options are praised because they help users find a better seal.

EQ customization was one of the strongest software features, with reviewers praising the ability to tune sound and create more personalized profiles.

EQ and sound personalization are considered useful and often effective, but one reviewer found the built-in five-band EQ limiting.

Reviewers described the overall tuning as balanced or safe, with the frequency range generally represented without harshness.

Frequency response measurements are acceptable but not perfect, with one review pointing to a clarity-related upper-range issue.

Instrument separation was praised when reviewers heard transient details and individual elements clearly, but one reviewer found separation below audiophile rivals.

Instrument separation and imaging are repeatedly praised as clean, precise, and unusually spacious for true wireless earbuds.

Reviewers who evaluated the built-in microphones found them useful or strong for calls in favorable conditions, though noise handling could struggle outdoors or in busy spaces.

Integrated microphones are good enough for calls in favorable conditions, with stronger praise from some reviewers than others.

The snap-together magnetic bud design on the TW2 was strongly praised for reducing loss and battery drain outside the case.

One reviewer values the ability to use either earbud solo without issue.

Lossless support is a major selling point for compatible Android/Snapdragon users, though some reviewers found the audible gains slight.

One reviewer noted that dynamics could feel slightly compressed at louder volumes, making maximum-volume clarity good but not perfect.

Maximum volume clarity receives strong praise in one review for remaining distortion-free at max volume.

Microphone noise reduction was a repeated weakness, with reviewers noting struggles against noise, exterior sounds, or wind.

Microphone noise reduction is the weakest recurring area, especially in wind, subway, and noisy street conditions.

Call quality was usually acceptable to good in quiet conditions, with some strong praise, but several reviewers found it only average outside controlled environments.

Call microphone quality is mixed: quiet-room calls can be clear, but noisy or windy conditions reduce reliability.

Midrange clarity was mixed: some reviewers heard clear vocals and lead instruments, while others said vocals or lower mids were pushed back by the bass-forward tuning.

Midrange is usually praised for clarity, vocals, realism, and texture, though one review found upper mids lacking.

Reviewers found phone-and-laptop use helpful, with multipoint and cross-device switching making the earbuds practical across platforms.

Multi-platform compatibility is mixed: Android gets the best feature support, while iPhone use loses codecs and showed some issues.

Multipoint was consistently valued for switching between phone, laptop, computer, or other devices, with reviewers describing it as useful, seamless, or reliable.

Multipoint works well for some reviewers and makes device switching convenient, though one review only found it OK in limited testing.

Passive isolation was usually strong when the seal fit well, though one review noted fit-related wind-noise leakage.

Passive isolation is praised when the fit is right, with reviewers noting strong physical blocking and seal benefits.

Portability was a recurring weakness because the case was often described as bulky, clunky, hard to pocket, or inconvenient, despite battery-life tradeoffs.

Portability is limited mostly by the chunky case, even when reviewers still like the case quality.

One reviewer said the Clear Vocal preset effectively fixed a vocal-detail issue, supporting a strong score for preset EQ usefulness.

Preset EQ quality is mixed; one reviewer preferred sound personalization over simple presets because presets reduced clarity.

Sensors were a clear weakness where reviewers wanted wear detection and criticized its absence.

In-ear detection is praised as highly accurate in one comparative test.

Sidetone was treated as useful for calls, helping users monitor their own voice or making the earbuds more office-friendly.

One review described initial setup as simple and fast, supporting a strong software/setup score.

Setup is usually described as simple and hassle-free, helped by the app and quick Bluetooth pairing.

Sound leakage is praised in one long-term review because the seal produced no leakage.

Reviewers mostly found the earbuds enjoyable and capable, with repeated praise for warm, detailed, or impressive sound, though one reviewer found the sound merely okay.

Sound quality is the strongest consensus area, with most reviewers calling the Momentum True Wireless 4 excellent or among the best-sounding earbuds.

Soundstage depth was praised by Expert Reviews but underwhelmed one YouTube reviewer who expected more depth from the large housings.

Soundstage depth/imaging is repeatedly praised for precision, holography, and immersive placement.

Soundstage width drew strong praise from some reviewers for wraparound or convincing staging, while one reviewer expected more width from the large earbuds.

Soundstage width is frequently praised as wide, spacious, expansive, or more open than competitors.

Spatial audio opinions were divided, ranging from disappointment or superfluousness to strong immersion and impressive 360 Reality Audio effects.

Spatial audio is a limitation: reviewers note it is missing, though one reviewer personally did not mind the omission.

Stability ranged from excellent in workout/head-shake testing to less reassuring on the bulkier TW2 design.

Physical stability is strong for many reviewers, with multiple reports that the buds stay put during movement or flights.

Touch controls are mostly praised as responsive and customizable, but one reviewer found accidental triggers very annoying.

Transparency/hear-through mode was useful for awareness and conversation, but reviewers disagreed on quality, ranging from invaluable to merely okay.

Transparency mode is often praised as natural and lifelike, but a few reviewers mention hiss or that AirPods/Bose still perform better.

Treble generally stayed clear and non-harsh, but several reviewers said highs lacked some sharpness, space, or detail compared with stronger competitors.

Treble is usually praised as crisp, refined, and non-harsh, though some reviewers found the default highs too restrained.

USB-C is present, but the only opinionated evidence is mild criticism of the front-facing port placement.

Value was generally positive because of battery life, sound, and features for the price, though one reviewer argued $150 was too high.

Value is mixed but favorable: reviewers often justify the premium price through sound and features, while others expected more upgrades for the money.

One review criticized the lack of built-in voice-assistant control, making this a weak point for hands-free assistant use.

Reviewers who commented on volume found adequate headroom and loud output, without major volume complaints.

Volume output is a minor weakness in one test, where the earbuds needed near-max volume for some tracks.

Water and sweat resistance was treated as useful for workouts, outdoor use, and peace of mind, though not as full waterproofing.

Water/sweat resistance is treated as useful and adequate for workouts, rain, sweat, and light moisture.

One review specifically described the earbuds as light and relatively inconspicuous, supporting a positive weight-comfort impression.

Weight comfort is mixed: some find the weight distributed well, while others feel heaviness after long sessions.
