Great sound and pairs easily with bluetooth and my Iphone. Self powered so no preamp or amplifier required, only one wire to a wall outlet and cable to tie the two speakers together. I have to say again what nice soud these speakers have and they have enough power to fill a normal size living room with plenty of volume if needed.

These speakers sound great. The mids and highs are crisp and clean. The lows are decent. A sub could help. The Bluetooth connectivity is very useful. Remember, these speakers are made for home use by audiophiles, not for professional work... although I don't think I would hesitate to use them for professional work in a pinch. Great value overall!
