The Nokta Makro 2.4GHz wireless headphones (green edition) offer solid wireless performance with the Simplex+, but the initial pairing process can be tricky if you don't follow the steps precisely. Here's the exact procedure that works reliably.
Quick Pairing Steps
Before starting, make sure your Simplex+ is powered on. The headphones' blue LED indicator should be on the same side as your detector for optimal wireless signal strength.
- Enter pairing mode: While holding the white button on the headphones, switch them to "on" position. Keep holding the white button until you hear the battery status beep.
-
Check battery status: The headphones will beep to indicate charge level:
- Five beeps = fully charged
- Four, three, or two beeps = medium charge
- One beep = low battery (charge before detecting)
- Continuous short beeps = critical battery level
- Start detector pairing: The blue LED will blink every 2 seconds. Now press the plus (+) and minus (-) buttons on your Simplex+ simultaneously. You'll hear a high-pitched beep.
- Complete connection: The blue LED switches to blinking every second, the wireless icon appears on your detector screen, and pairing completes.
Troubleshooting Connection Issues
If you're getting audio distortion or interference from nearby detectors, change the wireless channel. Access the wireless connection setting on your Simplex+ and use the plus/minus buttons to cycle through channels 1-5. Channel 0 turns off wireless completely.
Low battery is the most common cause of connection drops. When the battery gets weak, the headphones will unpair randomly during your hunt. Always charge fully before heading out.
Volume and Audio Settings
Don't look for volume controls on the headphones themselves - all audio adjustment happens through your Simplex+ detector settings. This keeps things simple once you're paired up.
After the initial pairing, your headphones and detector will connect automatically when you power both on. No need to repeat the pairing process unless you've used the headphones with a different detector.
Maximizing Wireless Performance
Keep the headphones' blue LED on the same side as your detector to maintain strong signal strength. If you're switching between ears frequently, you might notice occasional dropouts.
When you're not using wireless headphones, set your Simplex+ wireless setting to position 0. This saves battery life on both devices and prevents interference issues with other detectorists nearby.
Alternative Headphone Options
While the green Nokta wireless headphones work well with the Simplex+, some detectorists prefer wired options for guaranteed connectivity. The Simplex+ also pairs with other Nokta wireless models if you want to upgrade later.
For underwater detecting, you'll need waterproof wired headphones since the wireless models aren't submersible. The Simplex+ handles both wired and wireless connections seamlessly.
