Do these speakers need to be plugged into the computer's audio output, or do they have only the USB plug-in?

You need to connect both to the computer. Audio plug is for audio output and USB plug is for power supply.

These speakers just have connectors to hook up stereo wire from an amplifier to the speakers. They are not designed for use with a computer - It may be possible to do so, however, but you would probably need to have an amplifier between the speakers and the computer.

No audio outlet because speakers are built in.USB connection that you much change your sound output destination each time you switch back to your laptop speakers.

It is no way to plug these speakers into an audio jack, they only plug into the USB jack.

The usb is simply for power. You need to plug them into the headphone jack for it to produce sound.

the speakers are powered by plugging the USB cable into your computer. I turn my computer off at night, so they turn off as well. If you leave your computer on 24/7, You would have to unplug them when not in use.

It depends on your computer. Unless it is a "basement special" it probably has speaker "outs." Just plug in the logitechs. Best wishes. I really enjoy mine.

Sorry Don, they are plug in only. I am still more than pleased with the monitors. They are very very sensitive as far as picking up any sounds! Plus, the parent monitor is quite loud at its highest setting.

You plug the USB in then there is a little jack prong you plug in as well. In all honesty I liked them at first but not to impressed with them after a while. They do not interact well with all computers. I would try a different product if I were to repurchase this type of product.

You do have to plug them in to an AC outlet, but these are great little speakers, particularly if you have an office set up where you use more than one computer. Very versatile.

The plug is not USB. It is 'single pin' to the headphone/speaker port on your computer. Do note, that the speakers do require to be plugged into a wall outlet for power.

No speakers, no USB; just power, DVI, and VGA connections. Speakers would be setup through your computer.

You need to plug them into the wall outlet to power the built in sub-woofers. As others have said, if you don't you are not fully utilizing the full functionality.

Yes, just plug them into your USB (that's the only way you can). I've bought other brands that required plugging them into the USB, but this was the only brand I've purchased that worked as advertised.

You cannot plug these directly to your computer. You can hook these up to a receiver/amplifier and use one of the inputs on the receiver/amplifier to connect the line-out from your computer sound card.

The plugged in speakers override the laptop speakers. As soon as you unplug them the laptop speakers will be in play. I had to adjust volume on the speakers via the laptop though. If there were a volume control on the speakers it would be so much easier.
