A Great Pair of Small PC Speakers
Size: 1 Pair, Color: Silver, Size: 1 Pair, Color: Silver
These are great little pc speakers. They hookup easily, give off great sound, have an in line cord volume control and look great on the computer desk. The only thing missing is an on/off switch so you have to detach the usb to turn off the power, if desired, when the PC is on. My usb port is on the front of my desk top so it's easy.

Don't by used from amazon
Size: 1 Pair, Color: Black
Bought them used (don't do it plz) and they work well but at times I notice a hissing sound that always happens when I'm not playing any audio from them, and then there's times where there's no hissing sound. It's not the loudest but it can get kind of annoying. I'm sure it's because I bought them used but oh well, saved a few bucks and this is what I get. Other then that though the actual sound quality of the speakers is crazy good for the money. Speakers have nice weight to them and really decent bass to em as well. Just gotta give it 3 stars since Amazon didn't find it necessary to
1. Didn't clean the product before shipping so that it was in a presentable state, came to me hella dusty
2. Idk if anyone actually did long enough testing on this product when it got sent back, or else they would've fixed the hissing problem. I assume that was why it was sent back in the first place
3. Box was terribly packaged. No bubble wrap what so ever, the box the actual speakers were in also had nothing keeping them safe from getting smacked around during shipping. Multi billion dollar company can't even go the extra mile for the people who are paying them and keeping them in the business.

Perfect!
Size: 1 Pair, Color: Black
My husband wanted old-school plug-in speakers that had quality sound. These fit the bill and at an excellent price! They function exactly how the older speakers did, plug in and enjoy! No need to mount but you can if you wanted to. Easy to use and they have great volume. He does music making and video game development, so he needed the sound quality.

Unbelievable Performance!
Color: Black, Size: 6 Feet, Style: 5-Pack, Color: Black, Size: 6 Feet, Style: 5-Pack
I didn't expect such a great performance by these charging cables since even they are not brand. Decent price for a bunch of solid and plenty long charging cables. These are in high quality and charge fast the cell phone. Don't waste your money buying at the stores or the branded one.

Good reliable cable
Color: White, Size: 6 Feet, Style: 1-Pack
Very good quality cable works as expected with no issues at all. Easy to clean seems more durable than the OEM cable from Apple. Well pleased- I have several.
