Bluetooth accessories are a part of everyday life when using your iPhone – whether in the car, with headphones, or speakers. What many people don't know: iOS has a feature that helps your iPhone better recognize these accessories. This improves audio functions, measures levels more precisely, and accurately records hearing data. All you need is a quick trip to the settings.
Apple offers an option in iOS and iPadOS that allows you to categorize Bluetooth devices. It sounds simple at first, but it has a concrete benefit: Once your iPhone knows whether it's headphones, a car stereo, or a hearing aid, it can better adjust the audio output. This is particularly useful if you regularly wear headphones and want to keep track of your listening habits. It's also crucial for the accuracy of the volume display. This feature is quickly explained, but little known—and that's precisely why it's worth taking a closer look.
Marking Bluetooth accessories on the iPhone – what does it do
When you connect a Bluetooth device to your iPhone, iOS often automatically detects the device type. This works particularly well with Apple products like the AirPods or Apple Watch. For accessories from other manufacturers, however, the classification is often inaccurate or missing altogether. In these cases, you can manually assist. The selection of device types offered by Apple in Settings includes:
- Car radio
- headphones
- hearing aid
- Speakers
- Miscellaneous
The selected device type directly impacts the iPhone's behavior. For example, with headphones, the iPhone displays the current audio level in decibels via the Hearing Control in Control Center. These values are more accurate if the accessory is correctly categorized. Additionally, the Health app stores a history of your listening habits, including warnings when the volume is too high.
How to adjust the device type of a Bluetooth device
- Open Settings on your iPhone or iPad.
- Go to “Bluetooth”.
- Tap the info icon (circled "i") next to the Bluetooth device you want to edit.
- Select “Device Type”.
- Choose the appropriate category from the list.
If your accessory has already been correctly recognized, you don't need to change anything. If not, you can help it out by following these steps. This change is especially helpful for third-party headphones or speakers where iOS doesn't automatically determine the type.
What about AirPods and Apple Watch?
With AirPods and AirPods Max, the iPhone automatically recognizes them as headphones. Manual changes aren't possible, as they're unnecessary. The Apple Watch is also correctly identified. However, you can customize the name displayed in the Bluetooth list if you have multiple devices or want to distinguish them more easily.
