I had been put off from buying the Boostaroo T794 for awhile by unfavorable user reviews here and for their battery-powered versions, but as I read more of them I began to suspect that some were by people who had no notion of the relationships embodied in Ohm's law. Boosteroo's tables of specifications clearly show that the battery-powered and AC/USB models are identical, except for their power sources, and that Boosteroo's effectiveness related directly to the rated impedance of the headset connected to them, dropping off as the impedance level went beyond 24 ohms. However, some people just don't get it. I do, and am very happy with their product: the best little amplifier I've ever tried - hands down.

My endorsement is based on several decades of listening through various audio devices since I have lived with a hearing impairment since age 12 (now 62). So I have had many disappointments along the way. Not with Boostaroo, however. As soon as I received it, I ran a non-scientific test, finding the weakest audio signal station on our new HDTV and, with my 24-ohm Sony Studio Monitor headphones connected directly to it, adjusted the TV volume to the level at which I no longer had to lip read to understand what was being said. That level was 90%. I then connected the headset to my new Boostaroo and increased volume from zero to the same hearing acuity level. That reading was 20%! In fact, I couldn't go beyond about 40% without risking damage to my ears or the headset. In my book, that signal boost is better than outstanding, especially since I could detect no distortion or noise at any audio frequency. Amazing! I no longer have to drive others out of the room turning up the volume on our external sound system so that I can hear. I can now just use the separate, pre-wired headset directly from the mini-plug circuit on the TV for my level of stereo audio while they listen to their level from the room speakers.

Don't hesitate to buy this product if you want a top quality in-line amplifier for your headphones. Just be sure your headset speakers don't have a super-high impedance rating (listed on the box). Great product - I'll be buying more!

The T794 increases volume about 50%. The best feature is the USB power suppy. I do presentations and I am always on the road. This allows me to do a quick setup and I don't have to worry about IT dept. slowing me down. I don't have to look for power outlets and carry an ext. cords.

This product has been a great little friend, being on the road a lot, I can jam in my hotel room, and it takes up very little space. I use boosteroo with Harmon Kardon ball speakers and my laptop and/or Ipod and I have a nice sound system

Pros- very small, USB Power supply, connect mulitple speakers,

Cons - not much power

I have 2 previous Boosteroos and they were fine,this one for the fine is worthless-it has a TINY amount of boost-maybe a 30% or so volume increase at most.NOT worth the money, I am unlikely to ever buy a boosteroo product again. The vendor was very good, the product stinks.

Using to boost volume to small speakers connected to little LCD TV in kitchen. Wife was complaining all the time that she cant hear the TV over the kids when their being...kids. Powering unit using USB port on TV so it turns on and off with the TV. Significant volume increase to speakers (external speakers plugged into headphone jack on TV) quick easy fix when external speakers still weren't giving enough volume.

I wanted something to boost the line level output of my mp3 player in the car. I got a Fiio unit which was very nice BUT the problem was that it has a soft power button so needed to be turned on every time. I wanted something that could be buried and just come on with the ignition. This unit has a regular on / off switch and the boost is enough to make the line level much much better. Clean sound too.

If your device isn't sending a strong signal, this is the cure. Hooked between tv and auxiliary speakers, this Boosteroo works flawlessly, giving the punch to the sound that we needed.

The amplifier worked as described and I was able to increase the volume normally going to a headset, connected instead to the Boosteroo and then by a Y cable to the audio inputs on a digital television set. I have no electronic measurements, but only a subjective opinion that I could increase the volume 20 to 30 percent. The volume increase definitely helps, but I would like more. I like the fact that I can control volume with the TV remote rather than using the volume control on the laptop.

The Boostaroo works wonderfully to give the loudest, cleanest sound possible when splitting audio connections. Completely worth every penny I paid for it.

I did a research before order the item. However, the item is an used one and doesn't have the feature I need.

The return policy is great. After I return the project, I got full refund.

So, I would say the company is ok, however the product is really really bad. Not worthy for the time and money spend.
