Random disconnections on the Sony WF-1000XM6 are super frustrating. Good news: they're usually fixable. Let's go through the most common causes.
#1: Wireless interference
This is the culprit more often than you'd think. WiFi routers, microwaves, wireless keyboards, baby monitors—all these 2.4GHz devices compete with Bluetooth.
Try: Move away from your router. Switch your phone to 5GHz WiFi if you can. Don't use your earbuds right next to a running microwave (yes, really).
#2: You're too far away
Bluetooth reaches about 30 feet in ideal conditions, but walls and your own body block signal. If your phone is in your back pocket while you're walking around, that's a lot of interference.
Try: Keep your phone closer, same pocket as usual, ideally same room.
#3: Multipoint is getting confused
If you have multipoint enabled with multiple devices paired, the earbuds might be switching between them unexpectedly or competing for connection.
Try: Temporarily disable multipoint in the app and see if that helps. Or unpair devices you're not actively using.
#4: Firmware needs updating
Sony pushes firmware updates that fix bugs, including connection issues.
Try: Open the Sound Connect app and check for updates.
#5: LDAC is being finicky
LDAC sounds great but needs more bandwidth. In wireless-congested environments (apartments, offices), it can get unstable.
Try: Switch to "Connection Priority" instead of "Sound Quality Priority" in the app. You sacrifice some audio quality for stability.
#6: Battery is low
Connection gets weird when power is critically low.
Try: Charge fully before troubleshooting anything else.
Nuclear options:
Still having problems? Factory reset (hold both touch sensors for 10 seconds in the case). Delete the pairing from your phone and pair fresh. Clear Bluetooth cache on Android. If absolutely nothing works and you're under warranty, contact Sony—you might have a defective unit.
