1Mii Computer Speakers for Desktop Laptop Tablet, USB Powered PC Speakers, Small Speakers Wired with Volume Control, Stereo Sound with 3.5mm Audio Plug for Windows Mac Linux PCs

Volume is easy: because of the way sound carries in my house, all the bedroom TVs use a cheapo WIRED (you need a long aux cable or extension cables, those are cheap, and then plug in the power near the speaker) speaker on their headboard or nightstand so we don't all need to turn our TVs up to "public announcement" to hear them over each other. With our TVs we can set the speaker to a medium level and then up-down with the remote, but without a remote she could just turn the dial up or down. There are also simplified roku remotes on amazon etc.
