I hooked up my trusty old Logitech speakers to see if they still worked. They did, so I booted a game and sheepishly turned the volume way down in fear of annoying my neighbors, immediately remembering why I had these stuffed in a closet for almost 10 years.
Even if I lived in a soundproof house in the middle of nowhere I'd still be self-conscious enough to just use headphones instead 
Headphones make me anxious cos I can't hear my surroundings. I just use a sound bar and keep it low volume. Unless you have paper thin walls its not an issue, even when i lived in a house share my speakers didn't cause a problem.
