I'm going nuts trying to put together a sound system for my Ipod. I've tried the Iasus speakers with no success. I've tried the MixIt2 mini amp. But when I turn up the volume it distorts. I tried to call the guy at their website, but he hasn't returned my call. I took a pair of Sony Headphones, broke the headband off. & fitted them in my helmet. (took that idea from another thread) and they sound very good, but not loud enough. I've bought a couple of mini amps of Ebay. Going to try them when they arrive. I'm not a fan of "in the ear" phones. I don't want to have to stop, take my helmet off & adjust them. I use them a lot on my job & I know how they are. Anybody out there tried amplifiers? I know people talk about this a lot.
