Hiss is due to sidechannel and can be turned off through software.
A great USB sound card for the price.
By default, this card has microphone monitoring/sidechannel. That means that if you use a headset with this sound card, you'll hear the microphone input. This feature is very useful if you use close-back headsets. However, this also results in a low hiss that is audible at all volume levels.
Without sidechannel, the sound card will still hiss if you have very low impedance headphones. I only found the hiss noticeable with the volume slider on my headset set to 90-100%.
To turn off microphone monitoring/sidechannel:
1. Install the Sound Blaster software that comes with the sound card
2. In the Sound Blaster Play! 3 Control Panel, go to the [Mixer] tab.
3. Under Playback -> Speakers -> Monitoring -> Microphone, either move the slider to 0, or click the mute button on the right of the volume slider.
