 High-quality and versatile, but the Pro edition is even betterSep 03, 2008
By zemes
First of all, please note that they make two different versions of this thing. Make sure that you're getting the "Pro" version, which is not presently offered at Amazon.com, but sold by some vendors at very similar prices. The difference is that (1) the Pro version has both 1/4 and 1/8 (3.5mm) jacks for each channel, while the non-pro version has 1/8 (3.5mm) only; and (2) the Pro version has both 1/4 and RCA jacks for input, while the non-pro version has only 1/4 not RCA. But other than the connections, both units share the same electronics so should have the same performance.
This is a very well made unit, and can have variety of uses. I currently use it with an HDTV so that several people can watch TV wearing their headsets without disturbing others. The sound quality is top notch and the build quality is also excellent. Other apparent benefits include:
(1) Does not require the home electronics device (TV, for example) to have a headphone output to be used with this headphone amplifier (just to mind you, strangely many TVs don't have a headphone jack).
(2) Does not run the risk of damaging the headphone jack of the electronic device due to frequent plugging and unplugging.
(3) AC powered and does not require a battery.
(4) Has four channels, each with independent volume control.
(5) Can be used by maximum eight people (two headphones per channel).
Another thing worth noting is that, because this is an external microphone amplifier, it behaves quite differently from the headphone jack built-in the TV (or any other electronic devices). The microphone amplifier and the headphone(s) are essentially independent from the TV audio control. This has its inconvenience but also has its advantages. In the following, I'll list a few things. These may either be a plus or minus depending on your habits and use.
(1) Using an external headphone amplifier like this does not mute the TV speakers automatically like using a built-in headphone jack usually would. I personally found this to be an advantage because it allows you to leave the headphone plugged in all the time without the trouble and confusion of frequently plugging and unplugging the headphone. When you don't use the headphone, just put it down and watch your TV as you usually would. Sure the headphone would be working all the time, but headphones don't consume much power and don't really get worn by merely carrying a signal. Practically, if you're not wearing a headphone, you are not really using it. I leave my headphone plugged in all the time. The only time I think about it is when I pick it up to use it. How convenient. If you have frequently used a headphone, you would admit that the biggest hassle is to find your headphone every time when you need it, plug it in to use it, and unplug it after you're done. Having got used to my "perpetual headphone" with the external headphone amplifier, I would never go back to that business again.
(2) On most consumer electronics such as TVs, the volume control does not affect the line output, and thus does not affect the output signal level sent to the external headphone amplifier. As a result, the volume control on your TV does not affect the volume you here on the headphone. This again can either be a negative or positive depending on your use. You will need to manually adjust the volume of your headphones using the volume controls on this unit itself, which is somewhat inconvenient because it does not come with a remote control. But on the other hand, the fact that you can adjust the TV speaker volume independently (including completely turning it off by setting the volume to zero), could be a plus. For example, say you have a bunch of people watching TV while talking to each other making a noisy environment. You can plug in a sound insulating headphone into this unit to get much better sound from the TV program without having to change the TV volume or mute it to affect others. With a traditional built-in microphone jack, it's an either-or fight and you can't have both.

I love this beefy little amp!Jun 30, 2008
By S. E. Ellis
I've used this little amp for about 4 years now with a set of Sennheiser HD280Pro's. I use this with my computer at work to let me switch between headphones and my desktop speakers and it helps boost normal PC audio to new levels. I can get rich bass and as well as very high treble. More than a few times I've heard parts of music that I've never heard while listening to it anywhere else.
Once I even had the bass so well tuned that it rattled the coffee I was drinking in my mouth. It's a great buy and works quite well at work for me.
I've had a number of people ask what is that and where can I get it? I'm glad Amazon has it now.

The Rolls Royce of Headphone AmpsJul 22, 2008
By John L. Ebel
This headphone amp is small, good looking, and extremely well built. It feels and looks like it was made by the Swiss or Germans. Each of the four channels has its own volume control with outputs for 1/4" or 1/8" plugs. Inputs are 1/4" or RCA phono plugs. The sound is superb. I have it connected to my new HDTV.
I watch Classical, Opera, and Jazz DVD's. I'm glad I found this unit. You won't be disappointed.

 Rolls 4 channel Studio headphone amplifierFeb 08, 2011
By Barb Mullen
"acubarb"
I have had this product before.It is a good sturdy piece of equipment. However, my second one......ordered for convenience, had missing pieces.I didn't notice until days later until it was too late. I tried to contact the seller but couldn't. I also tried Amazon.com and got no reply. In the past this company has been good. Be careful!

Rolls Headphone AmpNov 29, 2008
By Stephen P. Clark
This is a great unit at an outstanding price. I use it to play audiobooks through a pillow speaker to fall asleep. Previously I was using a 200-watt stereo attached to a multi CD player. I dropped the stereo and played through this Headphone amp and saved a lot of electricity, heat, and noise (the 200-watt steereo had a fan). The price was great, the alternatives I saw were over a thousand dollars.
