Audio-Technica ATH-CKS5TW Solid Bass Wireless In-Ear Headphones

The ATH-CKS5TW in-ear headphones with Bluetooth® 5.0 technology pair powerful, high-fidelity sound with the convenience and freedom of a truly wireless design. Featuring auto power on/off, the headphones turn on and are ready to go as soon as you remove them from the included charging case. Return them to the case and they power off and begin charging. The headphones offer 15 hours of continuous music playback on a full charge, with 30 hours of additional power available from the charging case, so you can take your music with you wherever you go. Plus, the case is equipped with a USB-C battery jack, allowing you to recharge the case quickly when you need to do so.

The headphones are equipped with exclusive 10 mm drivers with dual-layer diaphragms. The combination of hard and soft diaphragm materials results in clear, full-range audio with superb bass. The sound is further enhanced by the included silicone eartips (available in four sizes: XS, S, M, L) whose thin, flexible design allows them to fit perfectly in the ear for excellent isolation and high-frequency sound delivery. Silicone 3D loop supports are also included to offer an even more secure fit.

As there are no wires connected to the headphones, controls and a built-in mic are situated on the headphones’ housings, giving you full, convenient control of your music and phone calls without needing to touch your smartphone or other paired device. Call quality is greatly improved by Qualcomm cVc™ (Clear Voice Capture) technology. Call audio also plays in both headphones, making conversations even clearer.

The ATH-CKS5TW headphones have an IPX2 water-resistance rating, which means they are protected from dripping water, such as rain and sweat. They are also compatible with the high-quality Qualcomm® aptXTM audio and AAC codecs for excellent wireless audio transmission.
