It plugs into the wall (120V AC) and has an internal power supply, no external transformer. It is not battery powered. Mine is connected to a desktop PC and sounds very good. I expect that it should sound just as good on a laptop.

Scott, you will need access to a wall outlet for these speakers. There is no way to power them without the wall plug.

The subwoofer unit will plug plug into your wall with a "wall-wart" style transformer. The amplifier is in this box and powers both the sub and the stereo satellite speakers. Just connect the mini 1/8" stereo plug to the line out on your computer and you're good to go. With the proper EQ setting, these cheap speakers really sound quite nice!

My speakers came with a Dell desktop PC & require connection to an AC 120V electrical source to work. They connect to audio out on the PC via a miniature jack.

No... Speakers must have a powersource. They are portable, if you have an AC power source. Great pair of speakers

Yes, this needs usb power to function at all. You don't have to use the sound, but usb is always necessary.

No only a receiver try to connect your computer to the receiver and you will get great sound

im tired of seeing people say this can only be used with Dell Monitors... thats completely untrue.... i have this exact soundbar, and ALL you need is to get the extra AC power adapter to use it with any other laptop or computer or whatever u want. I have it hooked up to a HP laptop right now with the AC adapter going to a power outlet. The sound is amazing. it doesnt have a place to hook onto tho, so you have to improvise there.

You need a receiver (with a built-in amplifier) and then a connection from your laptop to the receiver. These are not powered speakers. The speaker wire connects to each speaker and then to the channels in the back of the receiver.

Sorry, but no. The speakers get their power from a powered USB port on the connected device. There's two cables that come from the speakers - one is a USB connector that plugs into the PC or Mac for power and the other is an audio connector that plugs into the headphone jack of the PC or Mac. I bought these speakers to connect to a used Mac that had no audio to the speakers (but still had headphone audio) and they work great. Unlike the iPad Mini, the Mac has a powered USB port. I suppose you could try connecting the USB connector of the speakers to a USB charging plug, but I don't know if that will work and that seems inconvenient for a mobile device like the iPad Mini.

The speakers are powered via the USB connector, you don´t need an extra power source.

They are just speakers. They don't currently have anything powering them. So the short answer is no. Maybe they could if you added a reciever and hooked your computer to that, but you'd be better off (and will save money) if you go with a powered set made for a computer.

NO. A friend had a different speakers from a different manufacture that when he hooked them up to his computer he had it made some noises. He moved the speakers a way from the computer it work excellent. Hope this works for you.

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.

No. It is connected to the computer via USB. It connects to your audio system via RCA or XLR outputs depending upon the capabilities of your audio component(s). If you are using a preamp/power amp setup, the output will, of course, be directed to the preamp.

no. what I do is connect my laptop to two speakers used for the pc with a usb port. I use just fairly cheap $25 speaker set and then plug in a mic to the behringer. this works fine and I get good results.

No they don't. I have it hook up to my laptop & cell phone. but I have to choose which one to listen too. I hope that helps.

NO. External only. The whole deal with external sound cards, which this is on a miniature scale, is to by-pass the laptops super cheap on-board sound processor and hand off the process to a dedicated, full featured Digital Signal Processor, DSP. The laptop circuitry is optimized for size and cuts corners, clipping high and low tones. The sound card fully processes the signal for a richer, fuller sound. But.... it's an external, pre-amp signal for an external amplifier. The internal speakers are completely by-passed.

Yes, unless your amp Is passive, then you should connect the speakers through the back, normally speakers don't need an amp to power if they need 3.5mm jack to power, if the speakers/monitors are active (aka, have their own plugs and inside amplifier) then you do not need the amp to power them, as long as this wire is used you can plug strait into laptop/computet/phone anything with a 3.5mm jack
