Introduction:

BoostarooT.jpg (2479 bytes)Every so often you come across a product that is so simple and so functional that you say to yourself, "why didn’t I think of that". In this review we are going to take a look at such a product. It’s called the Boostaroo which is a miniature audio amplifier that claims to enhance audio listening quality and also extend battery life of any personal audio device. The better quality sound is a result of not having to push your system as hard to get the desired volume level thereby reducing distortion.

Boostaroo is the brain child of Tom Parker and is manufactured by Bowman, Inc. Parker came up with the idea on a flight to Hawaii with his wife. On the flight they tried to share a portable CD player by using a Y-splitter and was disappointed to find that the sound output when using headphones was about half of what he could get without the second set of headphones attached and there came the idea for the Boostaroo. Now I must interject into this story to note when I tested with a dual stereo headphone jack with my AIWA portable AM/FM cassette player I did get a volume decrease but it was not close to a 50 percent drop in perceived loudness.

Suffice to say that using a splitter does result in a volume loss which will vary depending on your output device and the impedance of your headphones. If you already have a portable system then your ears will tell you just how much volume loss you personally experience.

Getting back to the Boostaroo, it’s not the first time I have seen a device like this as several headphones come with an inline volume booster but its the first time I have seen it in a stand alone product. In this review we will tell you if we think the $19.95 Boostaroo hits the mark.
