I can hear hissing sounds coming out of my Icon product. Is it defective?

 

Generally speaking, this is not a problem related to the product. Some people with sensitive hearing and/or a noisy computer will end up hearing some low-level noise. In some cases, this could be an issue with the quality of the USB signal coming from your computer. Below are the results of an experiment we conducted to test the uDAC-2 combined with a Mac Power Book vs. the uDAC-2 and a ThinkPad PC. Highest Noise: Connected uDAC-2 to ThinkPad (X200), ran Foobar2K and paused the music. Could hear noise at around 12 o'clock volume setting. Moderate Noise: Connected uDAC-2 to ThinkPad without running Foobar2K. Could hear noise at maximum or after 3 o'clock volume setting. Less Noise: Connected uDAC-2 to Mac and ran iTunes, then paused the music. Could only hear slight noise at maximum volume setting. Least Noise: Connected uDAC-2 to Mac then switched Sound Device settings to Internal speaker and muted the volume. Could hardly hear any noise at maximum volume setting.
