AC power vs. USB: The trade-offs
Good speakers will produce full, detailed audio that sounds as the creator intended it.
Be aware, though, that finding strong bass response in this price range can be challenging. Without a subwoofer, 2.0 systems have trouble reproducing low frequencies. The manufacturers often use technological tweaks to beef up the bass notes, but these can sound boomy, and muddy the overall mix. If a deep, controlled bottom end is a priority, a 2.1 system might be a better investment. Both these options are prevalent in the sub-$60 price range. Usb-powered speakers reduce cord clutter, as they don’t need a separate power cable. However, they can’t supply as much juice as the AC variety, so they tend to produce lower volume and less bass.
