iFi iSilencer 3.0 USB sound booster

We are told ....

More and more audio products connect to devices like phones and computers via USB. This is convenient, but there’s a problem… USB connections are not designed specifically for audio; they’re electrically ‘noisy’ and swimming in EMI, which affects the quality of the audio signal. The iSilencer 3.0 solves this with Active Noise Cancellation derived from military radar technology, cancelling out noise by generating a signal that’s identical but in the opposite phase. This clever little gadget is a must for anyone who uses USB to connect an audio device and wants to maximise sound quality.
