    Comments about Livewire HA04 4-Channel Stereo Headphone Amplifier:

    I wasn't expecting much for the price, but I am pleasantly surprised! Very clean, and quiet (well...see below), good frequency response and can get VERY loud.
    For the *slightly* bad. The metal case is not wired to ground when shipped. When I would touch the case, I could hear buzz. Opened it up, soldered a wire to the case and to the ground on the board, and the buzz is gone.
    Still would recommend this, and if you are good with a soldering iron, you'll have a great little headphone amp.

      Comments about Livewire HA04 4-Channel Stereo Headphone Amplifier:

      Works well. Only issue is with the connection from the device to my audio interface. It requires 1/4" male connectors on both ends. Hard to find one less than 10 ft. If the unit supplied a 1 or 2 ft chord, that would have been ideal.. Also would be nice if it accepted 1/8" plugs as well.

          Does what it do. Only gripe, in channel 4, when you boost it to about 8, there is a lot of 'trash' (static). Other than that I am pleased with the purchase.

          Bought this to amplify my Headphones connected to my TV

          By intanet

          from Bronx, N.Y.

          Comments about Livewire HA04 4-Channel Stereo Headphone Amplifier:

          I got this to amplify my headset attached to the Optical output on the back of my TV. But first, I had to get an adapter (Optical Coaxial Toslink Signal to Analog Audio L/R RCA Digital Converter Adapter) but, unfortunately, even though my headphones have their own volume control, the volume was too low, even when all the way up. So I bought this HA04 and it did the trick. I connected it to the headphones and the adapter and I put the volume leaver all the way up on the amplifier channel I used and now, I have a volume range on my headphones. And, not only do I now have good volume range, it is not distorted all the way up either. Love it for that.
