Feel like you've dived into the front row of the concert, and turn the moment on with the ULT POWER SOUND™ series. Built for music lovers, it produces powerful deep sound designed to make your heart tremble. Prepare to feel the bass.
With two microphones in each earcup and Dual Noise Sensor technology to capture ambient sound, you can block outside noise everywhere you go, so the only thing you hear is your music.
With dual noise sensor technology and the Integrated Processor V1, ULT WEAR takes digital noise cancelling to the next level. Now you can truly shut out the world and enjoy a party for one—just you and your music.
The Integrated Processor V1 helps to eliminate external sound, with a low processing delay to make the Noise Cancelling more effective than ever.
Carefully designed with you in mind, a lightweight, ergonomic construction makes the most of the 35 hours battery life and will stay comfortable for long periods of listening.
In Ambient Sound mode, the ULT WEAR headphones allow in more ambient sound, thanks to precision feedforward and feedback mics, so you can enjoy a natural listening experience while staying connected to your environment. Plus, the Sony | Headphones Connect app allows you to adjust the ambient sound in 20 levels, or use the Focus on Voice setting to chat without removing your headphones.
Adaptive Sound Control is a smart function that senses where you are and what you're doing, then adjusts ambient sound settings for the ideal listening experience. It even recognises locations that you frequently visit, such as your workplace, the gym, or a favourite café, and switches the sound modes to suit the situation.
With 360 Reality Audio certified headphones and the Sony | Sound Connect app, optimise your experience by analysing your individual ear shape, and enjoy the ultimate immersive music experience2.

Just take the headphones off and the music stops—a capacitive sensor knows when you are wearing them. It also helps improve detection accuracy and design. Put the headphones back on and the music starts again.
Change track, adjust volume and take or make calls by tapping or swiping the touch panel on the side of your headphones. Need to quickly hear voices or sounds around you? Just place your hand over the housing to instantly turn your music volume down and let ambient sound in.
