Wireless Earbuds

True, Natural Sound Quality
High-Performance Sound Quality
The earbuds’ high-performance 9.8mm 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.
Convenient, Wireless Design
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.
Great Battery Life
The USB-C battery jack enables a quick charging time of two hours, after which the earbuds can be used continuously for up to eight hours. To help prolong battery life, the earbuds turn off automatically when left unconnected to a device for five minutes or in “waiting to be connected” status for 30 minutes.
Sweat/Water Resistant
The ATH-CKR300BT earbuds also have an IPX2 rating for water-resistance, which means they are protected from dripping water, such as rain and sweat.
