Koss SSR1 'Surround Sound Receiver (Discontinued by Manufacturer)

I'm not an audiophile but was quite surprised by the effect this little gadget can produce and with rechargeable batteries I never seem to be without it. It is portable which is a major plus just be sure if your using mp3's that you encode at 192 and not VB rate to keep the sound from being muddy. I have also found that you can easily spot fake lossless conversions with this because a low bit rate conversion will sound muddy or have a fluttering sound but without the adapter you would not notice. Which is faster than running through a spectrum analysis app.Cons: Poor volume make sure your input source has decent volume.

This is junk to any audiophile. The sound quality is very poor ie. distorted. Switches are unreliable, and there is no way to use external power so it eats batteries.
