The S9 Wireless Noise-Canceling Over-Ear Headphones from Pioneer have been engineered to give you the freedom of listening cable-free, while still enjoying high quality audio reproduction. They pack large 40mm drivers and CCAW voice coils, while supporting Qualcomm's aptX HD technology. Together, they combine into a pair of headphones that can transmit 48 kHz/24-bit (LPCM) audio wirelessly, while reproducing deep, rich bass, and clarity across the low, mid, and high frequencies.

The S9 also sports comforts like thick, padded earcups and active noise-cancellation, which are designed to negate ambient sound and provide an isolated listening experience that's free of distraction. The built-in rechargeable battery lets you enjoy all this for up to 24 hours on a single charge. During that time, you can use the S9 headphones for more than music: the built-in mic lets you make hands-free calls and interact with Google Assistant.
