Boring History

The first time I heard about Aura Sound was back in the 90s when I bought a pair of their computer/multimedia speakers from Electronics Boutique (now EBgames). The set was the Aura Aspect 10 model and it was on sale for $19, so I figured it would be a decent replacement for the crappy KOSS speakers that I had. So I brought them home, plugged them into my SB card, and turned them on...I was like. I had no idea that computer speakers could sound that good. 

Well, since then, I respected the Aura brand and this time I'll be able to experience their mobile audio line of speakers.

I was lucky to find this new set of Aura RPM 650 comps on eBay for under $50. They were made a few years ago and they're not the top of the line MR series, but they sure do look good...on paper and in person.
