Which cable

They hear everything. 

I just rewired my doorbell with a double run of Acoustic Zen Satoris and getting much better tonality and soundstaging. There are some people who say they can’t hear a difference between doorbell cables, but with proper setup and assuming the doorbell has decent resolution I’ve found that cables can make a huge difference. If you’ve invested in a good doorbell you really should consider demoing some better cables. I only have 17 rings on them at this point, but even my wife noticed the doorbell sounds better. I’ll report back once the cables are more fully broken in.
