One use for the pair and I haven't tried to power them indirectly with a usb adapter direct to an electrical outlet yet so don't know if that will work or not. Great sound for Small speakers and price and some cpu configs allow u to set them up as surround rear speakers if u ever get a better system down the road. My dell Inspiron i3000-3847 (bought via blind.com they Amazon for under $400 and as fast as a $2000.00 desktop) desktop set it up that way when I hooked my Bluetooth Sony soundbar and sub up and forgot to disconnect these. Very good vocal sound/treble for price but if u are a big music/movie buff u will want to upgrade and use these as ur backups like myself One use for the pair and I haven't tried to power them indirectly with a usb adapter direct to an electrical outlet yet so don't know if that will work or not.

Just one USB connection. All USB-powered speakers I've seen work the same way: the two speakers are connected by one wire, and one speaker has a USB cable and a stereo miniplug cable to connect to a computer. Interestingly, the first time I used them, I didn't have to connect to any audio source. As soon as I plugged into power, I picked up a local radio station. No thanks. I'd rather spend twice the money for ten times the quality. Walk away from these. Any Logitech set will make you happier.

Just one USB for the pair, in addition to a headphones jack. This is basically the same as what computers generally come with now. Excellent sound.

Actually, I checked. We have a pair here. As I thought, the power cable is on the far left speaker and the audio is on the right speaker. As I suspected, very poor design. I will not be purchasing these.

yes they do! I had the same question when I was looking to buy most of the vendors that sell them on Amazon stated it is one speaker. I had to call Harman Kardon to get the correct answer. the 2 speakers are connected to each other. I love mine I have them hooked up to my LED TV in living room and use Bluetooth to play music from my tablet.

Thank you for your inquiry. This bundle is just for the pair of speakers. You will need to purchase the cables separately.

Yes, the ones that I bought came as a pair. Good speakers for the money.....I would buy them again.

It is two, they come as a pair. I know you think for that price it is a steal, but they perform nicely for a surround sound speaker.

They come with a usb/audio combination cord. Basically you don't need to get anything else unless you want a usb extender or audio jack extender cable for more reach.

No, they all must be powered. I tried that at first and had to return the non-powered speaker. I bought a second powered speaker and they worked perfectly together. It's a little more expensive for the powered version but it was worth it for me.

It is a pair but only one will work after a couple of uses. DO NOT BUY THEM. One of my speakers broke the THIRD time I used it. Not due to carelessness, but because of poor quality. If you really want these, buy them somewhere other than on Amazon as you cannot return them despite this being a known issue with these.

They are wireless - you do not need a cable to connect them to a computer or your music-playing devices. However, they need a power cord and there is also a cable connecting the two speakers.

Yes. they are designed to be used as a set, stereo speakers for one device, cable to connect power source speaker to other speaker will sync them for this dual channel output.

These are not powered speakers, they need to be connected to a receiver or amplifier. If you wanted to use these with a computer you would first need to connect the pc's audio output to an amplifier.

Your provided with a link cable that connects both speakers together. So sound is heard from one source and out of the speakers.

No, you will need to purchase the power supply in addition to the speakers. There is an alternative model that comes with both.

They come in pairs. Sometimes amazon has specials where they will sell 2 pairs for a reduced rate. Just have to look around. Also, these are good speakers for the money but if your looking for good clean sound then step up to the KS line or better yet JBL or Polk/Infinity.

They have a standard headphone jack for sound. The USB port is for power only. They will work on any device that has a headphone port and a free USB port. Even without a USB port you can use a power adapter. We have used these speakers on a variety of devices.

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