Great upgrade

I wish that I had done this sooner. I was using some old Sony MDR-V600 headphones with my even older Technics SA-GX100 receiver. They never sounded very well together. So, I just stored the headphones for 20 years. Then, a friend told me about your amp and how it would work with the mis-matched impedance ratings of my components. So, I contacted your company and got great advice. Because of this, I purchased your amp, put new muffs on my cans, and I am tickled by how good they sound. Thanks a Million!

fosi headphone amp works well with my laptop and musical applications

clean sound, provides for easy to reach control (volume and tone) of my laptop audio when performing on stage. usb power from the laptop is one less cable problem. 1/4 inch and 3.6 mm in/outs are good design. nice price/value ratio.

A very useful multipurpose product. An excellent preamplifier for adjusting the sound according to the user's wishes. It works perfectly as a headphone amplifier and as an equalizer...
