Audio-Technica ATH-TWX9 - True Wireless Noise-Cancelling Earbuds

The Audio-Technica ATH-TWX9 Wireless Earbuds are designed to provide a premium true wireless listening experience with immersive sound, advanced digital hybrid noise cancellation, and customizable ambience control. Newly designed 5.8 mm high-resolution dynamic drivers are used to produce detailed audio across an extended frequency range of 10 Hz to 40,000 Hz, while compatibility with Qualcomm Snapdragon Sound™, Qualcomm aptX™ Adaptive audio, and Sony 360 Reality Audio allows high-quality music, video, and calls to be enjoyed.

A personalized listening environment can be created through five preset noise-cancelling modes, optimized adaptive noise cancellation, and a hear-through function. Clear voice communication is supported by dual high-performance MEMS microphones, beamforming technology, and Qualcomm cVc™ Generation 8.0 technology. Bluetooth 5.2 connectivity, multipoint pairing, low-latency options, and flexible single- or dual-earbud use are also provided for convenient everyday listening.

Up to 6 hours of continuous playback can be provided by the earbuds, while up to 18.5 hours of total use can be achieved with the charging case. A deep-UV LED sterilization system is integrated into the case to help eliminate bacteria and viruses from the surface of the earbuds. An IPX4 splash-resistant design is provided for the earbuds, while extensive customization can be accessed through the Audio-Technica CONNECT app.
