Duet – Add More Headphones

You can add more headphones by putting the Duet into pairing mode again and pairing each new headset one at a time.

Quick Check

1.  Turn ON the transmitter

● Slide & hold it to PAIR until lights flash red/blue

2.  Turn ON the new headphones

● Slide & hold them to PAIR until lights flash red/blue

3.  Wait ~3–5 seconds → lights turn solid blue = connected

Most Common Issue

The devices aren’t in pairing mode at the same time, so they can’t “find” each other.

💡 Tip:

• Minimize Interference: Wi-Fi routers, access points, and microwaves operate on the 2.4GHz frequency and can interfere with the signal. Keep these devices at least 2 meters away from your transmitter and headphones for best performance.
• You can pair up to 100 receivers—including Duet extra headphones, Harmony extra speakers, Quartet extra headphones, or Audiplex extra receivers—with the Duet transmitter.
