Greetings, I just bought a brand new JBL 305p MK2 and it was playing very great first 2 days but today Its just playing at an insanely low level that i can barely hear. It's also making popping sounds here and their. Im still hearing bass but im hearing a loud Hiss noise when i put my hear close to the tweeters. Sometimes when i turn the volume knob at the back of the speakers up and down, after a while it will just start playing fine for a few minutes and then a pop and it start playing low again... Which makes me to believe maybe their is a loose wire of something inside the speaker? Im not an audio technition but I would appreciate your advice. Thank you

I'm using a 1/4 Inch TRS to 3.5mm Direct to my Laptop.

HI 868Christo! Welcome to Gearslutz

Probably best to contact JBL and put in a support request. Like any company they will have the expertise and want their product users to be happy.

One issue I can see from your post is that the 3.5mm to 1/4 jack is probably not optimal so I'd advise to read the manual and see what IO connections they recommend.

Good luck.

Best, Arthur
