The ATH-CKR300BT wireless in-ear headphones give you true, natural sound quality in a comfortable, lightweight, easy-to-use model. The headphones’ high-performance 9.8 mm drivers are contained within specially designed compact housings to deliver rich, wide-range sound reproduction to ears of all sizes. Sound accuracy is further enhanced by each housing’s top-mounted PCB, which maximizes airflow for best performance.

The tethered wireless design of the ATH-CKR300BT places the in-line control, microphone, and battery pack all in the same convenient location, allowing you to easily control music and video playback, take calls, access the voice assistant on a Bluetooth® wireless device, and recharge the battery when needed. The USB-C battery jack enables a quick charging time of two hours, after which the headphones can be used continuously for up to eight hours. To help prolong battery life, the headphones turn off automatically when left unconnected to a device for five minutes or in “waiting to be connected” status for 30 minutes.

The ATH-CKR300BT headphones also have an IPX2 water-resistance rating, which means they are protected from dripping water, such as rain and sweat. Additional features include voice confirmation of power on/off, Bluetooth connected/disconnected, and low battery level; multipoint pairing function, which allows the headphones to connect to two Bluetooth devices at once; and AAC codec compatibility, for better wireless sound quality. The headphones come with four sizes of silicone eartips (XS/S/M/L), a 30 cm (12") USB-A/USB-C charging cable, and a carrying pouch.
