Transparency mode is a useful feature found on many new noise-canceling headphones, like theand the , the and , the and . Each manufacturer might call it something slightly different, but at its core, transparency mode is a clever way to help keep you aware of the world around you. It's designed for the moments when being fully absorbed in your music or a phone call isn't ideal.
Transparency mode might be useful for letting you hear the traffic around you, ordering a coffee from a barista, or just wanting to check if you really did hear someone knocking on your door (how dare they!). It lets you hear as if you don't have earbuds in or headphones on, without actually taking them off.
How it's implemented varies a bit depending on the headphone, but how it works is basically the same regardless of brand. And how does it work and how should you use it? Glad you asked.
What is transparency mode?
There's more to this mode than meets the, uh, ear. Most earbuds are designed to have a certain amount of passive noise isolation. Some are better at this than others. At one end of the range is the standard AirPods design, which hangs off your ear but doesn't go into your ear canal. At the other end of the range are most noise-canceling earbuds, which are designed to have a secure fit to block out as much ambient noise as possible. This is great for concentrating on your music or phone call, but there are countless situations where some ambient awareness is important.
by using microphones on the outside of the headphone to listen to the noise around you, then creating an inverse wave to reduce the volume of the incoming sound. Transparency mode does half that. It uses the same microphones to monitor the sound, but that sound is then just passed through the headphone, just like any other audio.
So why not just remove an earbud? That's certainly an option, but often isn't necessary. Say you're walking around an unfamiliar city. You still want to listen to your music, but being able to better hear traffic, train announcements and bike bells is invaluable. Maybe some rando starts talking to you and you want to see if it's a worthwhile conversation before you take out your earbuds. Or maybe you want to have your hands free for the short conversation, to use your phone for instance, without having to dig out your headphone case to store an earbud for a few seconds.
How to use transparency mode on AirPods, Bose, Sony headphones and more
How the mode works varies a bit depending on the headphones. On the AirPods Pro, for instance, you can toggle between no processing, noise canceling or transparency. On the Bose, if you remove one earbud, the other automatically goes into full transparency. Or you can enable it manually by cycling through the noise-canceling settings.
Sennheiser's Transparent Hearing mode is adjustable in its app so you can choose if the mode, when activated, keeps the music playing and mixes in ambient sound, or pauses the music and just has the sounds of the world around you.
Sony's Quick Attention mode drops the volume and ramps up the ambient sound when you touch an earbud. There's also an Ambient Sound Control slider in the app that lets you dial in exactly how much transparency or noise cancellation you want.
As a long-time fan of noise-canceling headphones, and as someone who regularly wanders through unfamiliar places, transparency mode can be super helpful. It's worth checking if your noise-canceling headphones have it, or if you're considering a pair, check the reviews to see how well it works.
