Audio-Technica ATH-CKS50TW2 Review: 15-Hour ANC Battery Monster

Quick Verdict: Who is the ATH-CKS50TW2 For?

The Audio-Technica ATH-CKS50TW2 is built for endurance and practicality rather than ultra-compact style. It is an excellent choice for travelers, commuters, and bass lovers.

Design & Comfort

Unlike many modern earbuds that focus on miniaturization, the ATH-CKS50TW2 takes a function-first approach. The earbuds are slightly larger than average, but the benefit is battery longevity and stronger low-frequency performance.

The Magnetic Snap Feature

A standout feature is the magnetic snap design. When you attach the two earbuds together magnetically, they automatically power off — even outside the charging case. This is surprisingly useful for desk work or short breaks, preventing accidental battery drain.

Fit and Feel

• Commuting & Gym: Offers a stable fit suitable for active use.
• Sleeping: Slightly bulky for sleeping or lying sideways.
• Isolation: The silicone tips offer decent passive isolation on their own.

Sound Quality

Audio-Technica leans into its heritage here. The CKS series is known for deep, punchy bass, and the CKS50TW2 continues that tradition. If you primarily listen to pop, EDM, hip-hop, or podcasts, you’ll likely enjoy the tuning.

• Bass: Strong, warm, and impactful without being muddy.
• Mids: Clear vocals with good separation.
• Highs: Smooth rather than sparkling; a safe tuning that avoids harshness.
• Soundstage: Moderate width. It is not expansive, but it feels natural.

Note: Audiophiles chasing analytical detail or ultra-high-resolution codecs might find it less exciting.

Active Noise Cancellation (ANC)

ANC performance is solid but not class-leading. It effectively reduces office chatter, traffic hum, and airplane cabin noise. However, it struggles slightly with sharp, sudden sounds.

For daily commuting and flights, it is more than sufficient. Additionally, the Transparency Mode works naturally and is useful for conversations or street awareness without removing the earbuds.

Battery Life – The Main Selling Point

This is where the ATH-CKS50TW2 shines. Most competitors offer 6–8 hours with ANC, making the CKS50TW2 one of the longest-lasting ANC earbuds in its price range.

• ANC ON: 15 hours
• ANC OFF: 25 hours
• Total (with case): Up to ~60 hours

The magnetic snap feature adds another layer of convenience by preventing idle drain, ensuring you get the most out of every charge.

Connectivity, Controls, & Durability

The earbuds utilize Bluetooth 5.3, ensuring stable connections. Multipoint support is included, allowing you to connect two devices simultaneously.

Physical vs. Touch Controls

The physical buttons are more reliable than touch controls, especially during workouts or rain. You don’t have to worry about accidental touches adjusting your volume.

Regarding durability, with an IP55 rating, these earbuds can handle sweat, light rain, and gym sessions without worry. There is also a low latency mode that is acceptable for casual video viewing.

Buying Advice

You’ll love the ATH-CKS50TW2 if you: Travel frequently and need long battery life, listen to bass-heavy music, work long shifts or remote jobs, or want durable, reliable earbuds with minimal charging anxiety.

You might want alternatives if you: Prioritize ultra-compact design, demand audiophile-grade codecs, or mostly listen to classical or acoustic detail-focused music.

Final Verdict

The Audio-Technica ATH-CKS50TW2 isn’t trying to be the smallest or flashiest earbud. Instead, it focuses on endurance, practicality, and reliable sound. Its battery life alone sets it apart in the crowded true wireless market, and the magnetic snap feature is surprisingly useful in daily life.

For travelers, commuters, and bass enthusiasts, this is one of the best value long-battery ANC earbuds available. While it may not satisfy hardcore audiophiles or minimalists, it excels at what most people actually need: lasting power, solid sound, and dependable usability.
