Using Newer Laptops with a Single Audio Jack
Most modern laptops include a single 3.5mm 4-pin combo port for both audio in/out. Many headsets still use separate headphone and microphone plugs that require an adapter.
How This Adapter Helps
Converts your single audio jack into two dedicated 3.5mm ports:
- Headphone output
- Microphone input
Works with dual-plug headsets, microphones, powered speakers, and single-jack mobile devices.
Headset Connectivity
1. Plug your headset’s headphone connector into the headphone port.
2. Plug your microphone connector into the microphone port.
3. Connect the adapter to your laptop’s audio jack.
You’re ready to go.
Microphone & Powered Speaker Setup
If you prefer not to use a headset, connect:
- A microphone into the mic port
- Powered speakers into the headphone port
Then plug the adapter into your laptop.
Ideal for Travel
Compact and durable—easy to pack with your laptop, tablet, or phone for mobile meetings and calls.

Please Note
- Not a headphone splitter; cannot output audio to two sets of headphones.
- Some devices may not work with all external microphones due to hardware impedance differences.
