Pixel Buds A-Series has a built-in 12mm dynamic speaker driver that provides clear, natural sound, and Bass Boost. Pixel Buds A-Series includes up to five hours of listening time on a single charge or up to 24 hours using the charging case. And with the ability to get a quick charge — about 15 minutes in the case gives you up to three hours of listening time, while it doesn’t support wireless charging but it has a USB Type-C charging port.
The new Pixel Buds A-Series come with Adaptive Sound, which increases or decreases the volume based on your surroundings. This comes in handy when you’re moving from the quiet of your home to somewhere noisy like a city street, or while jogging past a loud construction site.
Also, Pixel Buds A-Series use beamforming mics to focus on your voice and reduce outside noise, making your calls crystal clear (though of course, overall call quality depends on signal strength, environment, network, and other factors). Once your call is over, quickly get back to your music with a simple “Hey Google, play my music.”
