Google today teased new wireless Pixel Buds that will arrive next year for $179.

At a press event in New York City, Rick Osterloh, Google SVP of Devices and Services, talked up hands-free access to the Google Assistant and a long-range Bluetooth connection. The Pixel Buds will stay connected up to three rooms away indoors, he said. Outside, they'll work in a space as large as a football field.

The Pixel Buds should have 5 hours of listening time or up to 24 hours when you're using the wireless charging case.

The new Pixel Buds feature a custom battery, speakers, and sensors, Osterloh said. The battery is usually what bulks up wireless earbuds, but Pixel Buds sit "almost flush with the ear," he said. "It's easy to forget you're wearing them."

Spatial vents in the Pixel Buds are intended to let in the right amount of sound, and they'll dynamically adjust based on your surroundings—increased volume for a noisy cafe or the subway and lower for the privacy of your home, for example.

When you're on a call, beam-forming mics will focus on your voice.

Look for the Pixel Buds in spring 2020, when Oserloh promised more details about features like on-device machine-learning chips.

The original, wired Pixel Buds arrived in 2017. In our review, we found that despite the promise of helpful voice assistant features, Google combines an uncomfortable design, mediocre performance, and a high price tag for an unappealing pair of wireless headphones.
