A:AnswerThese speakers are not wireless, they do require you to plug them into your computer. They have a small wired remote you can put on your desk to control volume, but also plug in your headphones right there instead of digging around behind a desk or computer to find the plug for your headset.
A:AnswerYes! I hooked my Logitech - Z313 speaker system to my 40" 1080 HDTV, and it sounds awesome when I watch BluRay movies or play my PS2+PS3 games. If your tv has a headphone/audio output jack it should plug into it ok. :)
A:AnswerThe green plug on the back goes to your computer.
The 2 small speakers plug into a black stereo mini jack on the back of the subwoofer. Look at the metal plate on the back of the subwoofer; that's where you plug the satellite speakers in.
A:AnswerYes you can connect your iPhone to these speakers just connect the cord from the subwoofer to the headphone jack of your phone if it's a newer iPhone you'll need to use the lightning to 3.5 mm connector included with your phone
