are these speakers self powered?

No. It uses a 5.2V Power Supply that plugs to the back of one of the speakers.

The speakers aren't powered through any computer connection and require to be plugged into an outlet.

Hello,I see you had a question, to answer your concern: these speakers donot require batteries, nor do you have to plug into a electrical outlet. A USB plugin and sound input is all that's required.

These speakers are powered. As long as you have a standard line level audio out it should work. These speakers have a 1/4" phono jack and an XLR jack for inputs. A standard 1/4" male to male cable should plug the two together.

No, these are not self-powered speakers. They need some sort of amplification.

Yes they do- The usb cord coming from the speakers acts as a power source- unless you use a bb or iphone charger for the wall

no, these are not powered speakers and the volume would be controlled with a powered amp (stereo receiver). they have a very nice white grill. you can't see the speaker with the grill.

No they're passive speakers. You will need 'powered' mixer that also acts as amplifier.

Yes. They are NOT self powered speakers such as you would have when connecting to computer or iphone. They are traditional speaker that connects to a stereo or AV reciever. Of course you could buy an additional mini amp to use with them so could connect up a phone or midi source but that a whole other piece of equipment and topic.

No... That's a line-level output and these are not powered speakers. You could buy a stereo or surround-sound receiver to power these speakers and use a stereo 3.5mm plug to dual RCA plug adapter cable (or cables for surround sound) to connect the sound card to a line level input on the receiver (CD, DVD, tape, etc...).

These are standard 500 watt 8 ohm PA speakers. You will need an external amplifier to use them. These are not powered. I have had really good luck with these speakers.

No they are not, they are like stereo speakers with little clips on the back that the speaker wires plug into. In the four years I have had these speakers I have had no problems with them.

No, these speakers get power from a USB port and source input from a hard wired auxiliary cable. There are no other inputs or outputs

You will need some kind of power amp to drive these. Although small they are just a standard speaker as opposed to a powered speaker. Have a look at the Topping digital amps. I think they are great.

These speakers are not powered speakers. They connect using speaker wire to a receiver or amplifier. I have a pair of these connected to an inexpensive tripath amp and the amp takes the aux connector from a laptop or smartphone.

Wow, so many wrong answers!! These are passive speakers. They don't plug into a wall receptacle; they must be powered by an amp.

They are self-powered. As long as the device has a 3.5 mm jack, they will work with anything.
