The lightweight, ergonomic design of these Sony earbuds perfectly matches the shape of the human ear. That means they're super comfortable and stay in better - perfect when you're working out. With Active Noise Cancelling, you can block out life's annoying distractions so it's just you and your music. But when you need to listen out for your order at the coffee shop, Ambient Mode lets the world come flooding back in. And, if you get a call, Precise Voice Pickup with AI keeps it crystal clear, even when its noisy around. For hardcore music lovers, Sony's Digital Sound Enhancement Engine restores the harmonics that are lost during music compression, so your tunes sound more authentic. You'll hear every lyric, riff and beat exactly the way the artist intended.
