Bose SoundSport in-ear headphones – Charcoal : Product Description
Most wireless headphones use Bluetooth to communicate with the device, and in some cases, there may be a problem with the connection between the mobile app and the headphones.
If you are using wireless headphones with your mobile device, make sure your mobile device OS and headphone app are up to date.
Earphone-type wireless headphones are more susceptible to connection issues, such as broken connections, out-of-sync, and dropped calls than other wireless headphones due to their form.
In some cases, when communication is lost, your head itself is blocking the signal, which can be challenging to resolve.
Some headphone manufacturers say that updating the firmware may improve synchronization and other issues, but not all headphones.
Nevertheless, there may be solutions on the manufacturer’s website, including firmware updates, so you should check them out.
Of course, you need to keep your firmware up to date.
NOTE: If you see an authentication error, it’s too long. Move the device closer and try pairing again.
