The Marshall Code 50 I bought losses sound while in use. Turn the power on and off sometimes fixes it and also disconnecting it from the bluetooth device. However, recently I don't even connect a bluetooth device like my phone to avoid it, it still happens. Already tried installing the lates firmware, done factory reset, and still having this problem. I'm from the Philippines, the seller did not reply when I asked for assistance. I also don't know where I could bring it for technical support.
Our distrubutor in the Philiphines is Kraft Design Studio, they can be contacted on email@example.com and they will be able to suggest a service centre to look at your CODE50.
