| First of all, please note that they make two dfiefrent 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 dfiefrently 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 that 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 as using a built-in headphone jack usually would. I personally found this to be an advantage because this allows you to have the headphone plugged in all the time without the trouble and confusion of constantly 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 have my headphone plugged in all the time and the only time I think about it is when I pick it up to use it. How convenient. If you have frequently used the 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 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 volume to the external headphone amplifier. 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. 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 a much better sound from the TV program without having to change the TV volume to affect others or to mute the TV itself. With a traditional built-in microphone jack, it's an either-or fight and you can't have both. |
