“ The sound from my iPod Classic via The Total Airhead into my Shure SR440 headphones are truly great, and with four AAA-batteries it's an acceptable playing time too. The only problem I have experienced is contact problems both into the amplifier from the player and from the amplifier to the headphones. Apart from that I have no problems to reccomend this product to anyone with more than...” --Airheadfreak
“ I bought the BitHead as a replacement for my work laptop, where it is a big improvement over the cheap onboard sound card. Trivial to install and sounding very good. Highly recommended for this kind of job. On my desktop though I get mixed feelings. There I have an Asus D2X and a cheap Behringer HA400 headphone amp.

This is about a decade old amp, so I figured why not send it through the paces versus my big Fully balanced Audio GD? I got this amp through a trade recently I'm running the HeadRoom Little Amp With More Power Supply through my Audio GDs DAC Line out, set...” --Mshenay
“ A couple of years ago I had a big amp like this one but one with 4 headphone inputs and sold it on headfi. I can't remember very well how much difference there is between balanced operation and unbalanced (I only remember there was a difference in sound level - when I listened to a balanced and unbalanced HD650 both at the same sound level then the balanced HD650 phones sounded a...” --alexdemaet
