Best Versatile Headphone Amp, works great!

This amplifier works in nearly any situation. Crystal clear sound, volume, impedance adjust, 6.35mm - 1/4", 3.5mm 1/8", RCA imputs/outputs, plus iPhone/pod docks. Boot up and power light. Fits headphones and can be used as 1W Preamp.

Product most versatile I found so far. Can use for many devices, not limited as other brands.

I recommend this product.
