5. Cumail suas
5.1 Glanadh
Regularly clean your earbuds and charging case to ensure optimal performance and hygiene. Use a soft, dry, lint-free cloth. For eartips, remove them and gently wipe with a damp cloth, then allow them to dry completely before reattaching. Avoid using abrasive materials or harsh chemicals.

5.3 Stòradh
Nuair nach eilear gan cleachdadh, stòraich na fònaichean-cluaise anns a’ chùis cosgais aca gus an dìon bho dhuslach, milleadh, agus gus an cumail fo chasaid. Stòraich a’ chùis ann an àite fionnar, tioram air falbh bho sholas dìreach na grèine agus teòthachd anabarrach.
6. A ’dèanamh trioblaid
If you encounter issues with your FIIL Key Pro earbuds, refer to the following common solutions:
- Gun fhuaim: Dèan cinnteach gu bheil na fònaichean-cluaise air an cur air cosgais, air am paidhreachadh gu ceart, agus gu bheil an tomhas-lìonaidh air an dà chuid na fònaichean-cluaise agus an inneal agad air a thionndadh suas.
- Cùisean Paidhir: Turn off Bluetooth on your device, then turn it back on. Place earbuds back in the case, close, then reopen to re-enter pairing mode. Try pairing with another device to isolate the issue.
- Fòn-cluaise nach eil a’ togail cosgais: Thoir sùil air a’ chàball USB-C agus an inneal-atharrachaidh cumhachd. Dèan cinnteach gu bheil na ceanglaichean cosgais air na fònaichean-cluaise agus taobh a-staigh a’ chùis glan agus saor bho sprùilleach.
- ANC gun a bhith èifeachdach: Ensure earbuds are properly seated in your ears with a good seal. Try different sized eartips.
- Aon earbud nach eil ag obair: Place both earbuds back in the case, close it for a few seconds, then reopen. Re-pair the earbuds with your device.
