"The ShockWave SU-201s were less than impressive and a letdown. The sound quality was only marginally better than what comes with my laptop, and they require power provided by the USB port while a second TRS connection is needed for the audio. The layout of speakers is also disappointing due to the location of the volume control dial. As the volume is increased on the SU-201s, distortion takes over and whatever you are listening to becomes nothing more than a muddy mess."
