New iMac Supports High-Impedance Headphones
The new 24-inch iMac with the M3 chip supports high-impedance headphones, according to an Apple support document updated today.

The built-in 3.5mm headphone jack on the left side of the new iMac features impedance detection and adaptive voltage output, and the computer now has an improved digital-to-analog converter with support for sample rates of up to 96 kHz, allowing for users to listen to high-fidelity, full-resolution audio with supported headphones.
Apple's list of all Macs that support high-impedance headphones:
- iMac introduced in 2023
- MacBook Air introduced in 2022 or later
- MacBook Pro introduced in 2021 or later
- Mac mini introduced in 2023
- Mac Studio introduced in 2022 or later
- Mac Pro introduced in 2023
The new iMac launched today after being introduced at Apple's event last week. Key new features include the M3 chip, Wi-Fi 6E, and Bluetooth 5.3. The all-in-one desktop computer has the same design as the 2021 model with the M1 chip.
