But while exceptional sound quality may be at their core, we certainly don’t skimp on the convenience, either. For starters, the ATH-CKS50TW earbuds provide best-in-class battery life, with up to 20 hours of continuous use on a full charge. There’s also a fast-charge option that gives you roughly 90 minutes of use from a quick, 10-minute charge. The multifunction buttons on each earbud let you easily control music playback, volume and calls, plus select noise-cancelling and hear-through functions to block out and hear ambient noise, respectively.
Designed to connect people through sound, these hybrid headphones are equipped with advanced features making the ATH-TWX9 optimal workout headphones or commuter headphones. The splashproof headphone design (IPX4®-equivalent) makes these perfect for rain, water, and sweat. Choose from five preset noise-cancelling modes or optimize noise cancellation for your current environment simply by pressing the touch sensor on the left earbud. These non-slip, compact and ergonomic headphones are designed to ensure a secure, comfortable fit. Customize your experience with twelve different fitting eartip designs (4 diameter sizes, 3 stem lengths) for the most comfortable noise cancelling headphones.
With approximately 6 hours of continuous playback with up to 18.5 hours of extended use, these in-ear Bluetooth headphones are newly designed with 5.8 mm high-resolution drivers to deliver an extended high-frequency range and improved sound detail. Experience crystal clear call quality thanks to the Qualcomm® cVc™ Generation 8.0 technology. Minimize sound delay while playing games or watching videos with Low Latency mode. Compatible with Google Fast Pair , Sony’s 360 Reality Audio, multipoint pairing, and the A-T connect app, these headphones provide a customizable and seamless experience across devices.
Combining innovative acoustic technology with a snug, comfortable fit and convenient controls, the ATH-TWX9 lets you create an intimate sound space that’s all your own.
With five preset noise-cancelling modes to choose from, plus options for adapting noise cancellation to your current environment or for hearing the people around you, the ATH-TWX9 puts you in control of ambient noise.
Newly designed 5.8 mm high-resolution drivers deliver an extended high-frequency range and improved sound detail – perfect for use with the advanced Qualcomm® Snapdragon Sound™, Qualcomm® aptX™ Adaptive audio, and Sony 360 Reality Audio technologies.
