✅ 1. Your PC is using the wrong Bluetooth driver (MOST COMMON)
If your PC is using a generic Microsoft Bluetooth driver, it often fails to load:
- A2DP Stereo (audio out)
- HFP Hands‑Free (mic + audio)
So the headset shows up as input only.
✔ Fix
- Press Windows + X → Device Manager
- Expand Bluetooth
- Look for your adapter (Intel, Realtek, Qualcomm, etc.)
- Right‑click → Update driver
- Choose Search automatically
If it still doesn’t work:
✔ Install the manufacturer driver manually
- Intel Bluetooth → Intel Driver & Support Assistant
- Realtek Bluetooth → Your laptop/PC manufacturer website
- Qualcomm → Manufacturer website
Once the correct driver installs, Windows will suddenly show both:
- PLT V5200 Stereo
- PLT V5200 Hands‑Free
✅ 2. Your Bluetooth adapter does NOT support audio profiles
Some desktops (and cheap USB dongles) support keyboard/mouse only, not audio.
If your Bluetooth adapter does not support:
- A2DP (audio out)
- HFP/HSP (headset mode)
…then the PLT V5200 will never show as an output device.
✔ Fix
Use a Bluetooth adapter that supports A2DP + HFP.
The most reliable ones:
- TP‑Link UB500
- ASUS USB‑BT500
- Avantree DG80 (audio‑focused)
✅ 3. Windows paired the headset in “Call Control Only” mode
Plantronics headsets sometimes pair as “Headset” only, not as “Headphones.”
✔ Fix
- Go to Settings → Bluetooth & devices
- Click your PLT V5200
- Click Remove device
- Turn off the headset
- Turn it on again and hold the call button until it enters pairing mode
- Re‑pair it
After re‑pairing, Windows should show:
- PLT V5200 Stereo
- PLT V5200 Hands‑Free
