Excerpt: I hooked thes up to a raspberry pi (including drawing power from the Pi's USB) and I was moderately suprised to see that everything worked, even with the other USB port powering a WiFi dongle. I was just playing short announcements and the sound quality is more than good enough for my needs.
Summary: This is a great option for powerful, low cost external speakers (I picked these up for $15). I was looking for something to add to my desktop machine to listen to lectures and youtube videos. You can really jack up the volume and it comes through clearly without distortion.
Summary: Very good cheap speakers, they are of good quality for the price, they have a nice look and are easy to position the distance from the laptop through leaves munch to be desired. the leads at the Back get tangled easily and then that greatly reduces the positions for the speakers.
Summary: These speakers were bought as a last minute thing, but they are excellent. They plugged in all easy with the on/off switch and volume on the side and they're really compact. Great value for money and quite a clear sound.
