Guides
Every guide here starts with what is actually possible, including when the answer is “nothing, and here is why”. Bluetooth finding works well within a room and not at all on a flat battery, and being clear about which situation you are in is most of the work.
- How to find lost Bluetooth earbuds that are turned off
The three states earbuds are actually in when you think they are off, a 60-second test to tell them apart, and what finds them in each case — including one lost bud.
- How to find a lost Bluetooth device that is off
Off, asleep and out of range look identical and need different responses. Diagnose which you have, then run the matching search — live scan, last-known location, or a grid search.
- How to find lost AirPods, including when they are off
Find My in the right order, why the charging case confuses the location, what the Find My network does and does not cover, and what to do once the battery is flat.
- How to find lost Galaxy Buds, including when they are off
SmartThings Find can ring the left and right bud separately and locate them through nearby Galaxy devices — while they have charge. Plus the non-Samsung fallback.
- How to find lost Bluetooth headphones
Over-ear headphones are the easiest Bluetooth device to find: big batteries keep them broadcasting for days, and they are usually still paired to a laptop somewhere.
- How to find a lost Bluetooth speaker
Speakers transmit strongly and hold charge for days, so they should be easy — until the idle timeout powers them off. Why the first hour matters more than the technique.
- How Bluetooth finder apps work (and what they cannot do)
Advertising packets, RSSI, and why no single phone can point an arrow at your earbuds. Read this before you trust a distance estimate.
- Bluetooth signal strength and distance: reading RSSI properly
What a dBm reading means, roughly how it maps to distance, and how much each wall, cushion and body costs you.
Where to start
If something is missing right now, go to the device-that-is-off guide and run the diagnosis at the top — it takes a minute and decides which of two very different searches you should be doing. If it is specifically earbuds, the earbuds guide covers charging-case behaviour and the single-lost-bud case in more depth.
