Hama "Passion Clear II" Bluetooth® Headphones, True Wireless In-Ear, ANC, App, b

If you have lost or misplaced your Bluetooth headphones, you can easily locate them using the "Hama Home" app. To do this, use the app to query the last known location via GPS where the smartphone and headphones were connected via Bluetooth. Tip: if the earpieces are still active or switched on, the Bluetooth connection can be re-established within a radius of 10 metres (depending on ambient conditions). If the headphones and mobile phone reconnect immediately, you know for sure that it is still where you last had them.
A prerequisite for the Find function for wireless headphones is that the app can retrieve location information. You can specify this in the app settings.
