How to Find Your Lost Sony WF-1000XM4 in Minutes
Losing your $248 WF-1000XM4 is stressful. But if they still have battery, they're broadcasting an invisible Bluetooth Low Energy signal right now. EarBuddy turns your phone into a radar that can detect that signal and guide you straight to them.
Why Headphones Connect Isn't Enough
Like its successor, the WF-1000XM4 can only be located through Sony's app when actively paired. There's no standalone find feature for disconnected earbuds.
How EarBuddy Finds Your WF-1000XM4
Because Sony uses Bluetooth Low Energy (BLE 5.2), your WF-1000XM4 constantly broadcasts a short-range signal — even when disconnected. EarBuddy scans for this signal and shows you real-time signal strength on a radar display, guiding you physically to the device.
Open EarBuddy and start a scan.
Walk around the area where you last used your WF-1000XM4.
The BLE signal from the earbuds will appear on EarBuddy's radar.
Move toward stronger signal readings.
Search the area thoroughly when the signal is at maximum strength.
