Recently bought 19" TV for kitchen. Good picture but unpleasant sound (not unusual for modern small TVs).
Looked into getting a mini amp and speakers but concerned about spaghetti junction behind TV. Noticed these USB Logitech Z120s and realised that the TV has a USB socket. Looked at the reviews but they all seemed to be about connecting to a PC/laptop.
So, for the record, I can report that I now have these speakers connected to the USB and headphone sockets of the TV. They work fine and provide much improved sound, well worth the price paid. They don't entail a separate mains lead with the associated issue of turning them on and off. They switch on when the TV comes on and at least in the case of this particular TV they don't draw power when the TV is on standby. If the TV has to be changed at some point they'll be available to supply the same enhanced sound for its replacement.
