How to Find Your Lost Sony WF-1000XM4 in Minutes
The WF-1000XM4 introduced Sony's V1 integrated processor and were notably heavier at 7.3g per earbud than their XM5 successor, which makes them more likely to work loose from smaller ear canals during physical activity. A well-documented issue with the XM4's foam ear tips degrading over time can cause fit problems that lead to unexpected drops. EarBuddy picks up their BLE 5.2 signal at a consistent 30 feet, and because the XM4 case uses a distinctive rounded-square shape, it often gets mistaken for a small container and shoved into miscellaneous drawers.

Why Headphones Connect Can't Find Your WF-1000XM4
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.
Step-by-Step: Find Your Sony WF-1000XM4 With EarBuddy
Your WF-1000XM4 uses BLE 5.2, broadcasting at 2.4 GHz with a typical range of 30 feet indoors. With up to 8 hours (24 with case) of battery life, there's a good chance it's still transmitting. Here's how to track it down:
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.
