Bottom Line
Choose the ATH-CKS50TW if you want marathon battery life and a warm, bass-friendly sound; Skip them if you need class-leading ANC or a compact pocketable case.
Best for
Listeners who want huge battery life and a warm, bass-forward tuning they can fine-tune with EQ, plus multipoint for daily phone-and-laptop switching.
Not for
Anyone who needs a tiny pocketable case, effortless controls or top-tier ANC/transparency, or who relies on wear-detection auto-pause.
Verdict
Audio-Technica’s ATH-CKS50TW are built around two real strengths: marathon battery life and an energetic, warm sound with genuinely excellent low-end. The Connect app adds a proper EQ, codec toggles and latency/ANC controls, and multipoint plus IPX4 make them easy daily drivers for commuting or workouts. The tradeoff is ergonomics: the buds and especially the case are bigger than most, and the small top-mounted buttons can feel fiddly and may nudge the fit. Noise canceling and hear-through are useful but not best-in-class, and there’s no wear-detection auto-pause.
Pros
-
Battery life is repeatedly described as best-in-class, commonly around 20 hours in the buds (about 15 with ANC) plus roughly 30 more from the case.
-
USB-C charging is consistently included and straightforward.
-
Water resistance is consistently positioned as workout-friendly (commonly IPX4, with some coverage citing higher ratings on newer variants).
-
Low-latency mode delivers good audio-video sync, with most reviewers reporting minimal lip-sync delay for video and casual gaming.
-
aptX/aptX Adaptive support makes these particularly attractive for Android users seeking higher-quality Bluetooth audio.
-
Codec support is a strength, with SBC/AAC plus aptX and aptX Adaptive mentioned often, and some app control over codec selection.
-
Stability is generally strong once fitted, with multiple workout and head-movement anecdotes indicating the buds stay put.
-
Tuning trends warm rather than strictly neutral, but multiple reviews call it well-balanced across the range with good overall coherence.
-
Android support is strong thanks to features like Google Fast Pair and aptX/aptX Adaptive compatibility.
-
Multiple ear tip sizes are included (often four), helping with fit and seal, even if durability concerns pop up in a few reviews.
-
Build quality is widely seen as robust for the price, though a few note the silicone tips feel thin and may wear over time.
-
Bluetooth stability is typically strong (including longer-range anecdotes), but a few users report occasional dropouts, especially in multipoint or obstructed scenarios.
-
Charging is USB-C with strong fast-charge results (about 10 minutes for roughly 90 minutes playback); most reviews note no wireless charging on the CKS50TW.
-
Bass is the headline: deep extension and punch are repeatedly praised, though it can sound forward on bass-heavy mixes.
-
The seal provides solid passive isolation, sometimes good enough to reduce noise even before ANC is enabled.
-
EQ customization is a highlight, offering a five-band EQ and useful adjustments to tailor bass/vocals and overall balance.
-
Across reviews, sound is described as warm and engaging with strong detail for the price, especially after EQ tweaks; a minority find it merely average without tuning.
-
Separation and imaging are strong for the class, keeping transient details in context, but it does not match higher-end audiophile flagships.
-
Multipoint is widely appreciated for switching between phone and computer, though there can be slight delays and occasional reliability quirks.
-
Soundstage is often called convincing and well-staged for true wireless, though a few impressions place it closer to average rather than expansive.
-
The Connect app is feature-rich (EQ, noise modes, codec selection, updates, extras like soundscapes and ear-profile tools) and is generally reported as stable.
-
Comfort is generally good once the right tips are found, but the larger housings can feel bulky or less secure for smaller ears.
-
Preset EQ modes (such as Bass Boost and Clear Vocal) are frequently cited as helpful and can meaningfully change the listening profile.
-
Noise control is adjustable in the app with ANC on/off and hear-through options, making it easy to tailor for different environments.
-
Weight is noticeable for some (and a few describe the fit as unbalanced), but others find the buds comfortable for long sessions.
-
The app includes a locate/find function for the earbuds, which is useful if you misplace them.
-
Sidetone/side-talk features help you hear your own voice more naturally during calls, which several reviewers appreciate.
-
Call quality is mostly clear in quiet settings, with mixed results outdoors or in noisy rooms; some experiences are excellent while others report average performance.
-
Midrange is generally clear, but the stock tuning can let bass mask lower mids and push vocals back; the Clear Vocal/EQ options help restore presence.
-
Treble is usually smooth and non-fatiguing; some reviewers want more sparkle or sharpness, while others note it stays crisp at higher volumes.
-
Hear-through/transparency is generally usable and fairly natural, but it can be mild and is not on the level of the best implementations.
-
The case is generally sturdy with clear battery indicators and secure retention, but its large footprint is a common complaint.
-
ANC performance ranges from average to solid-for-the-price: it reduces low-frequency rumble well but is not class-leading versus premium models.
-
At very loud listening levels, some note dynamics can feel slightly compressed or squashed, even if clarity remains decent.
Cons
-
Physical buttons help avoid accidental touches, but their placement and size can be fiddly; some find multi-tap actions or locating the buttons frustrating.
-
Design is functional but plain, and the size is frequently called bulky compared to sleeker rivals.
-
Noise reduction on calls is inconsistent, with wind and busy-street noise sometimes bleeding through and degrading intelligibility.
-
Spatial audio/360 Reality Audio is a mixed bag: some find it immersive, others dismiss it, and it is limited by supported services.
-
Portability is the main physical downside: the case is chunky and the buds are large, so jeans-pocket carry can be awkward even if bags and jacket pockets are fine.
-
Voice assistant support is limited in some coverage, with at least one review noting a lack of built-in voice-assistant control compared with certain rivals.
-
Wear-detection sensors are a notable omission in multiple reviews, so playback does not auto-pause when you remove a bud.
FAQ
How long does the battery last in real use?
Most reviews highlight roughly 20 hours in the earbuds and about 50 hours total with the case; with ANC on, many cite closer to 15 hours in the buds. Actual results vary with volume, codecs and ANC settings.
Do these support multipoint Bluetooth?
Yes. Multiple reviews describe multipoint pairing for two devices (for example, phone plus laptop), though switching can sometimes have a brief delay.
Is there wireless charging?
Most coverage of the ATH-CKS50TW notes USB-C charging with fast-charge but no Qi wireless charging. If wireless charging matters, verify the exact package/version before buying.
How good is the noise canceling and hear-through mode?
ANC is generally described as useful for everyday rumble and office/commute noise, but not on the level of top-tier models from Apple, Bose or Sony. Hear-through is workable and fairly natural, but not best-in-class.
Do they auto-pause when you remove an earbud?
Several reviews call out missing wear-detection, so playback may not automatically pause or resume when you take a bud out or put it back in.
