ComfortWe refined the details of comfort, creating a new class of in-ear headphones with a customizable fit that forms an exceptional seal for Active Noise Cancellation. You’ll feel your music, not your headphones. Choose from three sizes of soft, flexible silicone tips that click into place - Large, Medium or Small. These internally tapered tips conform to your ear shape, keeping AirPods Pro secure. And with vents helping equalize pressure, you feel like there’s nothing in your ears.Active Noise CancellationAirPods Pro are the only in-ear headphones with Active Noise Cancellation that continuously adapts to the geometry of your ear and the fit of the ear tips — blocking out the world so you can focus on what you’re listening to. Noise cancellation is continuously adjusted at 200 times per second for truly immersive sound, so you’re fully tuned in to your music, podcasts, and calls.Want to hear what’s happening around you? Just press and hold the force sensor on the stem to jump between Active Noise Cancellation and Transparency mode — which lets outside sound in, and allows things to sound and feel natural when you’re talking to people nearby.Audio qualityPowerful bass is delivered by a custom-built high-excursion, low-distortion speaker driver. An inward-facing microphone hears sound as you do. AirPods Pro then fine-tune the audio by adjusting the mid and low frequencies. The amplifier powers the speaker driver to remove background noise and works with the H1 chip to control listening levels. A super-efficient high dynamic range amplifier produces pure, incredibly clear sound while also extending battery life.Performance and designTech-packed yet compact, AirPods Pro are built around our System in Package design — featuring the H1 chip that powers everything from sound to Siri. The Apple-designed H1 chip employs 10 audio cores, creating incredibly low audio processing latency that enables real-time noise cancellation. Use the force sensor to easily control music and calls, and switch between Active Noise Cancellation and Transparency mode.BatteryMore 24 hrs of listening time with multiple additional charges in the case.Up to 4.5 hrs of listening time on one charge.Around 1 hr of listening time on only 5 minutes of charging.
