Before you ask.
Can I make my guitar amp Bluetooth?
Yes — the 6dot35 plugs straight into a 1/4" input, so any guitar amp, bass amp or PA speaker becomes a Bluetooth speaker for streaming music or backing tracks at line level.
Bluetooth receiver with 6.35mm jack?
The blafili 6dot35 is exactly that: a 1/4" TRS (6.35mm) Bluetooth 5.1 music receiver with aptX HD, TWS stereo pairing and a 10-hour rechargeable battery.
What should I do if I hear a pop or crackle after pausing music?
If you notice a sudden pop or crackle about 30 seconds after pausing playback, a firmware update is available to resolve it. Contact blafili support with your model name (XLR or 6dot35), and we’ll provide the correct update and guide you through the steps.
