What you’re dealing with
The long battery is the real advantage. Where AirPods give you a five-hour window, a Sony pair gives you days.

Once the battery is gone: Thirty hours of playback and a long standby mean a pair lost this week is very likely still transmitting.
Where it usually is
Overhead lockers and seat pockets
The single biggest cause of lost over-ears. If the last-seen pin is an airport, this is the answer.
Office drawers
Put away to keep the desk tidy, in a drawer that is not yours.
The car boot
In the bag you took out and put back.
A gym locker
Left hanging on the hook when the bag came out.
How to search for it
- Check the last-seen map firstBefore you search a room, find out which building. A pin saves you from searching the right way in the wrong place.
- Scan from the middle of the roomNote everything that appears, then select the device you want so the rest of the list drops away.
- Walk and watch the signalSweep in a straight line, give each position a few seconds, and turn 90 degrees when the reading stops rising.
- Search inside things, not across themA strong signal with nothing visible means it is underneath or inside something. Fabric and metal block Bluetooth badly.
Tips specific to sony wh-1000xm headphones
- Search the scan list for WH-1000 rather than the friendly name, the advertised name is the model string, not whatever you named it in the Sony app.
- If two people in an office have the same model, save yours in My Devices so it is pinned and named in every scan.
- Fold-flat cases block signal. If the reading is weaker than expected, the headphones are probably in their case inside a bag.

Common questions
What does LE_WH-1000XM4 mean in my Bluetooth list?
It is the Bluetooth Low Energy advertisement name for the Sony WH-1000XM4. LE marks the low-energy profile and the rest is the model number. Seeing it means a pair is nearby and powered on.
Can I find them if they auto-powered off?
Sony headphones enter a standby rather than a hard off after auto power-off, and generally remain discoverable. A pair that has been fully drained will not appear.
