A:AnswerAccording to my scale they weigh a little over 1lb each. I don't know about a TV unless it has a plug for earphones. These are not surround sound speakers but do well for my PC.
A:AnswerI had looked at the manual for my Hp OMEN by HP Obelisk Desktop 875-0018 tower all I see in the manual is for a audio-out and audio-in jack it doesn't specify if its a 3.5 audio out jack?
A:AnswerI would think so! I have a Dell laptop computer and use the smaller Logitech speakers for that. Sound is great! The larger speakers I purchased were for a small flat screen TV. If you use those for gaming on your computer they would be amazing!
