👍 Great for

Ideal for bass enthusiasts, users who want to leave the charging case at home, and those needing durable, washable earbuds for sports.

✓ Pros

• Magnetic Switch allows for easy power management and case-free portability [S1][S2]
• Exceptional battery life: up to 25 hours on earbuds alone (NC off) [S1][S2]
• IP55 water and dust resistance, allowing the earbuds to be washed with water [S1][S4]

Review

The ATH-CKS50TW2 is a True Wireless Stereo (TWS) earbud from the 'SOLID BASS' series, designed for those who prioritize powerful low-end frequencies. Its most innovative feature is the 'Magnetic Switch,' which allows users to turn the power ON by separating the earbuds and OFF by snapping them together magnetically [S1][S2]. This design enables a lifestyle where the charging case can be left at home [S4]. Equipped with a 9mm SOLID BASS HD TWS driver and an acoustic duct, these earbuds are engineered for deep bass [S1][S2]. They feature hybrid digital noise canceling for immersion, alongside 'Hear-through' and 'Talk-through' functions for environmental awareness [S1][S2]. Battery life is a key strength, offering up to 25 hours of playback on the earbuds alone (NC off) and up to 65 hours with the case [S1][S2]. They are IP55 rated for water and dust resistance, making them washable and suitable for sports [S1][S4]. They also support LE Audio (LC3 codec) for lower latency and power consumption, provided the connected device is compatible [S2].
