The following two statements do not jive

1) "Tembo Trunks don’t use batteries"

2) "Tembo Trunks amplify the music from your iPod’s earbuds to 80dB of clarity-enhanced Stereo Sound (3x the sound)"

Powerless sound amplification!

Additionally, "clarity-enhanced"? Fur realz? Lets hook N of these bad boys up in series and get N times the clarity!
