Transparency mode is a listening feature that lets you hear the world around you while still enjoying your audio. Instead of sealing you off from ambient sound, it uses the headphones’ built-in microphones to pass outside noise through to your ears. This can be useful when you need to stay alert to traffic, hear announcements, or have a quick conversation without removing your headphones.
What is transparency mode?
Apple’s support documentation describes Transparency mode as a setting that “lets outside sound in, so you can hear what’s going on around you.” It is available on AirPods Pro, AirPods Max, and later AirPods models that include active noise cancellation. The feature is the counterpart to Active Noise Cancellation (ANC), which uses outward-facing microphones to detect external sounds and then counters them with anti-noise. Transparency mode, by contrast, allows those external sounds to pass through intentionally, so you remain aware of your environment.
On supported AirPods, you can also use Adaptive Audio, which Apple says adjusts the noise cancellation automatically based on your surroundings. With certain models, listening modes can even reduce your exposure to loud environmental sounds. Switching between Transparency mode, ANC, and Off is done by pressing and holding the force sensor on the stem of an AirPod, or by using the Control Center on an iPhone, iPad, Apple Watch, or Mac. The exact steps vary by model, so it is best to follow the instructions in your device’s manual.
How transparency mode works
Apple’s setup guide explains that Transparency mode relies on the same outward-facing microphones used for noise cancellation. Instead of generating anti-noise, the headphones pass the microphone signal through and play it through the speakers so that ambient sound reaches your ears naturally.
Because the feature depends on a good seal, Apple notes that Active Noise Cancellation and Transparency mode work best when your AirPods Pro fit well. If the eartips do not create a proper seal, the balance between outside sound and your audio may be less effective. Some models also allow you to customize which listening modes cycle when you press the force sensor or the listening mode button, so you can set up the controls to match how you use the headphones most often. Our guide to how active noise cancellation works covers the other side of these controls.
Open-ear designs: a different path to ambient awareness
While transparency mode uses electronics to let sound in, open-ear headphones take a physical approach. According to beyerdynamic’s explanation of open-ear technology, these headphones sit outside the auditory canal rather than inside it. Because the ear canal remains unblocked, ambient noise such as traffic or nearby conversations is still audible while you listen to music or podcasts.
Open-ear headphones transmit sound either through bone conduction, where vibrations travel through the skull bones to the inner ear, or through air transmission, where small speakers positioned in front of the ear canal send sound waves directly to the eardrum. Beyerdynamic says air transmission delivers high frequencies more clearly than bone conduction. The company points out that the maximum volume is naturally limited by the open construction, which can be a safety benefit in itself.
This design also brings other advantages. beyerdynamic highlights safety, because you can hear traffic and other hazards during outdoor activities. Hygiene is improved because nothing is inserted into the ear canal. Wearing comfort is often better, as there is no pressure inside the ear, and the headphones can be so light that you almost forget you are wearing them.

Safe listening and staying aware of your surroundings
Being able to hear what is happening around you can contribute to safer listening habits, but it does not replace the need to manage volume and exposure time. The World Health Organization (WHO) explains that noise-induced hearing loss can result from regular exposure to loud or prolonged sounds. Sensory cells in the ear can become fatigued after a loud event, causing temporary muffled hearing or tinnitus. Over time, repeated exposure can lead to permanent damage.
WHO recommends several practical steps to protect your hearing. Keep the volume on your device at no more than 60% of its maximum, or use an app to stay below an average of 80 decibels (dB). Well-fitted, noise-cancelling headphones can help you avoid raising the volume in noisy environments. In very loud places, earplugs or earmuffs are advised. The safe listening time drops quickly as sound intensity rises: at 80 dB you can listen for up to 40 hours per week, but at 90 dB the safe duration is only four hours per week. For reference, WHO gives examples such as a doorbell at around 80 dB and shouted conversation at roughly 90 dB.
If you often use transparency mode or open-ear headphones to stay aware of traffic or people around you, it is still important to monitor your overall sound exposure. Many smartphones have built-in sound level monitoring, and free apps can track your in-ear sound dose. Warning signs that you may need to have your hearing checked include persistent ringing in the ears (tinnitus), difficulty hearing high-pitched sounds like birdsong, or trouble following conversations in noisy places. If you notice any of these, WHO advises contacting a health professional. For any hearing concerns, see a doctor or audiologist.
Frequently asked questions
Can I use transparency mode with only one earbud?
Apple’s support documentation indicates that on AirPods Pro you can enable a setting called “Noise Cancellation with One AirPod” in the Accessibility section of your iPhone or iPad settings. Once turned on, pressing and holding the force sensor on a single AirPod will cycle through the available listening modes, which can include Transparency mode. The exact behavior depends on your model and how you have customized the button cycle, so check your device’s manual for details.
How is transparency mode different from open-ear headphones?
Transparency mode uses the headphones’ microphones and internal processing to capture outside sound and play it back through the speakers. Open-ear headphones, as described by beyerdynamic, physically sit outside the ear canal and allow ambient sound to reach the eardrum naturally, without any electronic pass-through. Both approaches let you hear your surroundings, but the technology behind them is different. Open-ear designs do not require a battery for the awareness feature, while transparency mode is an active feature that needs power.
Does using transparency mode help protect my hearing?
Transparency mode itself is not a hearing protection feature. It helps you stay aware of your environment, which can be useful for safety, but it does not reduce the sound level reaching your ears. The World Health Organization emphasizes that protecting your hearing depends on keeping the volume at safe levels, limiting listening time, and using hearing protection in loud places. If you have concerns about hearing damage, consult a doctor or audiologist.
