Hi, a_yush. Welcome to Nokia Support Discussions. :smileyhappy:
What happens to the headset prior to this issue? By the way, what is the exact model of the Nokia Purity headset? Is it the, Nokia Purity Pro Wireless Stereo Headset by Monster BH-940? If yes, you may try resetting the hardware by doing the following steps:
- Unfold headset to power-on
- Go to Bluetooth pairing mode by long-pressing Bluetooth key
- When in Bluetooth pairing mode perform factory reset by pressing simultaneously the Bluetooth and Play/Pause keys.
- After the successful reset you hear the voice prompt “Factory settings restored”.
- Fold and unfold device to power it on again.
- The unit is not OK if it is failing to perform this hardware reset operation.
Just let me know if it makes any difference. 👍
