Was this working ok previously or is this the first time setting it up? It sounds like it's ready to pair.

Does resetting them by holding the two volume buttons down simultaneously for at least 5 seconds help ?

It sounds like the device may have just lost it's pairing and need pairing all over again. Delete any historical profile of pairing for the device on your phone/audio streaming device then start the process all over of searching for nearby Bluetooth devices. Hopefully the T450BT will appear in the list.

Hello Mr. John, it appears, but the problem persists. I managed to pair the device and hear about 7-10 seconds plus the device turns off.

Some people have found that it does this when still plugged in to charge. Is yours still connected Mario ?

Ok... but when you do charge it it appears to charge ok ? It takes the normal amount of time for the charging complete ? I'm wondering if it has a bad internal battery.
