High impedance headphones on MacBook Pro 2021

Good news for audiophiles out there. Apple’s new M1 Pro and M1 Pro Max MacBook Pros feature an adaptive voltage headphone amplifier, meaning it optimizes itself to the headphones you’re using. With these two models, gone is the concern whether 80 ohm or 250 ohm headphones will work.

“When you connect headphones with an impedance of less than 150 ohms, the headphone jack provides up to 1.25 volts RMS. For headphones with an impedance of 150 to 1k ohms,┬áthe headphone jack delivers 3 volts RMS. This may remove the need for an external headphone amplifier.”

So, if you love Beyerdynamic’s DT 990 Pro 250 ohm Open-back Studio Headphones, you can rest assured that your new MacBook Pro will power them with aplomb.
