Can anyone recommend solid colored paper to make envelopes? Cardstock is too thick.

I am searching for an adapter with 3.5 or 4.4 mm male headphone jack on one end and usb c male on other end. This will allow me to hook up my DAP with my JBL Charge 6. Looking for a good quality connection. Does adapter quality matter or will any adapter give me great sound?
