 A must have gadget. October 23, 2008
The problem i had was that using my i-pod with small portable (battery operated) speakers while listening to spoken word ie. podcasts were that the speakers themselves were not powerful enough to hear unless you sat right beside them without any background noise. a quick search on google for an 'inline i-pod amp' took me to the boostaroo. it had mixed reviews but i decided to give it a go and was not disappointed. it really does what it claims. i find the a good amplified output that really adds to the audio you are listening to.
i do (or once did) however agree with some of the previous cons about the boostaroo.
1. it does distort music that is ripped at 128kps, though maybe thats the flaw of the low compression rating. listening to music ripped in 256kps or loss less in i tunes and its pretty perfect.
2. the battery choice for this is strange, i mean i had never heard of AAAA batteries before this, i think mini torches etc.. use them. i too could not find a rechargeable set anywhere; though a quick search again and i did find some, there are 6 of them inside a 9v duracell battery! the most incredible thing about the battery is not the size but how long they last. i read somewhere that is was 20 hours of playing time per set, not so. i bought my boostaroo just before christmas and changed the batteries (22/10/08) yesterday! despite the fact i use it every day in work (5 days a week) for about 6 hours, simply amazing!!
3. the battery cover is cheap and light but since you never (hardly ever) have to open it its not really a problem.
4. i must not have read the instructions because i just unplug the cable to turn it off but even i forget to its no big deal as the batteries last 10 months!
in summary i would say buy one of these if you need that extra bit of volume. yes it costs about 45 euro but it does the job brilliantly and i reckon it will last years and years. so pleased was i that i ordered another boostaroo just in case my first one broke; which it didnt.
i use the 'linx b-tube' speaker by the way and think its pretty good, the boostaroo just improves it. without it i couldnt really hear my podcasts in work, and they keep me sane!! :)
 Good amplification, but bad sound quality June 1, 2008
5 out of 5 found this review helpful
I bought this amplifier to solve the problem of low sound level using an MP3 player and good quality 300 ohm headphones. Certainly this amplifier produces more than enough amplification, but seriously messes around with the sound. The unit uses a crossfeed circuit that results in the sound having a permenant echo, like its gone through a reverb unit. It would be fine if you had the option to turn off this "distortion by design" feature, but you can't. I don't like all my studio recordings sounding like they're being played in a live concert environment. If you want to add this kind of sound effect, most MP3 players allow you to do this, so why build this in to the amplifier? I am very disappointed with this unit. So much so, that I have since purchased another amplifier that does a good job of amplification, and nothing else!
Grado SR80's on 160GB iPod Classic April 13, 2008

Yeah, very good volume increase - does what it says on the tin...
However, there is a small but noticible background hiss. This is actually heard as soon as you connect your headphones, ie. before you start playing any music. This hiss doesn't increase as you crank the volume up, so it's more noticible if you play on quieter tracks (acoustic, classical etc)
You may not notice quite as much on a cheaper pair of cans, and my Grados could have picked it up more perhaps? I'll try on my Senheissers when I get chance and report back...
Expensive and flawed.. but does the job. March 31, 2008
3 out of 4 found this review helpful
I got the black version of this. It was only necessary as I had foolishly replaced my trust Creative Zen Nomad Jukebox with a (black) 160gb Ipod Classic. As many may or may not know, any of these bought in Europe have a ridiculous (and so far unremoveable) 'Volume Cap' manufactured in. This means that if you happen to be on a plane, train bus - or even sometimes a car, you struggle to get the volume up to an acceptable level. And don't think expensive headphones will change this; I've got Bose Quiet Comfort 2's and I still struggled to hear some tracks properly over the engines on an Airbus!
So, after several months of trawling for software hacks/fixes etc, I came across the Boostaroo. My likes and dislikes are as below:
Likes:
+ Great sound - they really do enrich the sound from the Ipod (which is just as well!)
+Great Volume - Yes, they do provide a more than considerable boost to the output of my Ipod classic.
Dislikes:
- Expensive 30 is a lot of money to pay to pay for a pre-amp
- Build quality is poor.. pretty much on a par with something you'd find in a poundstore!
- The battery cover is almost impossible to get off - and its hasd/thin plastic so could snap easily.
- The Batteries: These are "AAAA" and so far I havent been able to find any rechargeable ones anywhere - the manual says they last about 3 hours - but I haven't fully checked yet..
- Fiddly; according to the instructions you can't just unplug - you have to follow a set procedure of disconnecting.
- You need a separate black lead (something else to misplace) and also I can't understand what the little thing on the case with the hole is for..
So, in summary, if you aren't happy with the volume on any MP3 player - this will fix it - and boost the quality at the same time. But is it worth around 30... The choice is yours.
