The easiest and simplest thing to do to hear the TV better is to increase the treble and decrease the bass.  This is free and easy to do.  Check your TV manual for instructions or call a TV technician. 

Turning up the treble and decreasing the bass oftentimes can make the sound more clear and sometimes helps to reduce the annoying effects of the background music which can be annoying.
