Break in and room acoustics are both very important. Find a playlist, any playlist on your favorite streaming service and let them rip for a couple of days. Then try listening to them again. Carpet, book shelves with books, curtains are some simple things you can use in your room. Here’s a cheap way that I still use. I bought one of those cheap, foldable room dividers and tossed a comforter over it.
All the best.
