Got these speakers just so I could have sound, but the speakers turned out to be better then I expected. The sound good and they have plenty of volume. I adjusted everything to full volume and it was way too loud. The only knock on these speakers is their built in volume knob is on the speaker cable and hangs below my desk (no big deal for me I set the hardware volume to almost max then adjust with my software volumes. The USB power made setup easy and they are compatible with anything with a line out port. Good speaker at a great price.

Bang for your buck!

Size: 1 Pair, Color: Black

Bought these for my Dell computer because the built-in speakers were hard to hear. These made a big difference right away. Sound is much louder and clear for music, videos, and everyday use. They don’t have a lot of bass, but for the price I really can’t complain. Good speakers if you’re looking for a simple and affordable upgrade.

Best used with Laptop

Size: 1 Pair, Color: Black

These speakers are of better quality than they seem and will probably surprise most if used properly. When hooked up to a computer or laptop (via usb and aux), they work AMAZING. But when I tried to hook them up to my ps5, the quality went way down— the sound ceiling and especially base is almost non existent when plugged into a gaming system. I still use them for my ps5 but only because I live in an apartment—when I move, I’m upgrading. However, the quality for the price is so good that I bought another pair for my classroom. It’s more than enough sound to get the job done. Classic, Solid Amazon brand quality getting the job done.
