They're actually not bad sounding for the price, pretty warm. Used them on acoustic guitar, drum overheads and vocals with half decent results back in the day (have sold them now)
But I've found with all the Red 5 Mic's that they've got quite alot of self noise when compared to pretty much any decent mic from shure/sennheiser/audio technica etc.
I can post some clips in the next couple of days if you'd like?
