The product comes with a mini DSP-like array of features that allows you to tune the sound stage the way you would like it to sound. This means that you will never be constrained by the recording quality of any MP3 song or game as you would be able to tune the sound accordingly. However, even if you leave everything at default settings, the sound is already enhanced as compared to the onboard sound chip/card of your notebook/PC. This product is best matched to a 5.1 sound system. I was using a system (low budget at $55) with a 25 watt RMS subwoofer and the highs and lows, clarity and deep bass from the system has blown my friends away when played as it matches and even surpassed systems that would cost ten times more. They simply could not comprehend that music can sound so good with strong separation of channels and enhanced through stereo surround from 5 speakers. THe whole front area becomes a huge sound stage. The pinnacle of sound came when I managed to hook up a Cambridge Soundworks 5.1 megaworks with THX Certification and 500 watts of pure RMS power. Though old technology and already a defunct model, the whole setup made the same group of friends realise that you do not have to spent thousands to enjoy incredible sound. This also has caused them to rethink about going wireless when analogue can actually sound so good. My only grouse is that it would be great if the product can be a little smaller and come with a retractable/adjustable USB connection. The one given is a little too long. Highly recommended with 5.1 setup.
