No, a standard MacBook Pro’s 3.5mm jack will not work with a TRRRS plug, and it may not fully work with TRRS plugs, as the jack is typically designed for TRS stereo headphones and may not be wired to correctly receive a microphone signal from a TRRS plug or handle the signal from a TRRRS plug.

While some older MacBooks with 3.5mm jacks support TRRS headsets, modern MacBooks with only USB-C ports require a 3.5mm to USB-C adapter to use TRRS headsets. [1, 2, 3, 4]
Understanding Plug Types

  • TRS (Tip-Ring-Sleeve): This is the standard for stereo headphones, with two black bands on the plug. [2, 5]
  • TRRS (Tip-Ring-Ring-Sleeve): This is common for smartphones and tablets, adding a microphone or control function, with three black bands on the plug. [2, 6]
  • TRRRS (Tip-Ring-Ring-Ring-Sleeve): This is less common and has even more conductors than TRRS, but it is not supported by standard computer audio ports. [2, 7, 8, 9, 10]

Why it Doesn’t Work

  • Incorrect Wiring: The 3.5mm jack on a MacBook Pro is typically designed for TRS connections, but many phones have TRRS jacks to accommodate both audio and microphone input. [1, 2]
  • Microphone Detection Issues: When a TRRS plug is inserted into a TRS jack, it may create a short circuit that prevents the laptop from detecting the microphone, even if you hear audio. [1, 11]
  • Electrical Shorts: If a TRRS plug is inserted into a TRS port, it might cause a short between the microphone and ground conductors, which can lead to a poor connection and no sound or a faulty connection. [7, 11]
  • Lack of Support: Even if the port is designed to be TRRS compatible, there is no standard and the connection may not work. [1, 2]

Solutions for Modern MacBook Pros
If you have a newer MacBook Pro with only USB-C ports, you will need a USB-C to 3.5mm adapter to connect a TRRS headset. These adapters allow you to use your existing headset by translating the signals to work with your MacBook’s ports. [3]
For a working TRRS headset connection:

  • Use a USB-C to 3.5mm adapter on your MacBook Pro. [3]
  • Connect a TRS/TRRS cable with correct wiring and impedance. [1, 5, 12]
