Summary: At its highest volume, I can barely hear the speakers. I regret having purchased them. I didn't use them immediately, and by the time I did, I felt it was too late to return them. Don't waste your money.
Summary: Pros- For it's size I was impressed. It uses the power of a computer port to drive an amplifier which means you don't need batteries or a wall wart for power. It has an on/off and adjustable tone and volume. Cons- It uses one of your USB ports if your limited for ports.
Summary: I purchased these speaker because they were recommended by a friend. I am very pleased with sound quality at such a reasonable price. The service was very prompt I will recommend these to others. These speakers are of higher quality than others I purchase at a higher price.
Summary: A LOT SMALLER THAN I EXPECTED, BUT THEY SOUND DECENT FOR TINY SPEAKERS (6" HIGH) AND A GOOD DEAL FOR $11 DELIVERED. HAVEN'T HAD THEM LONG SO I CAN'T SPEAK FOR THEIR LONG TERM PERFORMANCE BUT SO FAR THEY ARE DEFINATELY WORTH IT.
