ATH-CK1TW Buying Guide: Washable Wireless Earbuds

The Audio-Technica ATH-CK1TW is designed for those new to true wireless earbuds or those prioritizing daily usability [S2]. **Key Features and Performance** Designed to fit comfortably even for users with smaller ears, it includes four sizes of soft silicone eartips (XS, S, M, L) [S1, S2]. A standout feature is its IPX5/7 water resistance, which allows the earbuds to be washed with water [S1, S2]. However, it is explicitly stated that they should not be used in high-temperature or high-humidity environments like bathrooms, as they are not completely waterproof [S2]. **Call Quality and Connectivity** Equipped for telework and online classes, the earbuds feature a microphone layout that reduces wind noise and a noise reduction function to minimize ambient domestic sounds [S2]. The 'Sidetone' function allows users to hear their own voice during calls, reducing the feeling of occlusion [S1, S2]. Connectivity is stabilized via a simultaneous left-right transmission system, supporting Android Fast Pair and multi-pairing across multiple devices [S1, S2]. **Battery and Control** It offers approximately 7 hours of continuous playback, extending to a maximum of 21 hours with the charging case [S1, S2]. Operation is handled via an intuitive one-button system, which also allows users to toggle a Low Latency Mode to reduce audio-visual lag during gaming or video playback [S1, S2].
