I needed new speakers after the knob on my old speakers broke off. They still worked but I just got sick of the knob falling off and having to put it back on. I was surprised how small these speakers were but I was even more surprised at how nice they sounded. They have no knobs just 3 little If you're looking for speakers that are affordable, small and easy to use you will love these. They are very simple plug and play nothing to figure out. Just plug them in and the computer will recognize them and install. They are not real powerful so if you're looking for major booming loud sounds you will be disappointed. They do the job they were meant to do which is to let you listen to music or videos and have a good strong sound. With a usb you can use these for laptops or desktops, and use only one cord so less clutter, and the speakers shut off when you shut down your computer. There is a volume up and down button and the middle button will mute the speakers, which is a nice feature. Good value for the money you can't go wrong with these.I think you would be happy with the sound on these small but powerful speakers. I have had these for three months and so far so good!! Sound Quality Pretty good if your just looking for sound so you can watch videos and listen to music. Ease of Use Very simple, plug and play, volume control and mute are on the front right speaker. Durability These have been dropped numerous times and still work like their new. There are no nobs to fall of either.
