So I hate to be that guy, but I'm about to take a dump all over these IEMs. If you're a fan, look away!
I was in need of buying a ton of cables from Monoprice for a laboratory setup, so while I was at it, I decided to order the 8320s. Just figured I'd give them a try, because for 7.11, why not?
Well, honestly, I think they sound terrible. I mean, for the price, they're not bad, because what can you get these days for 7.11? Maybe my pair is defective but you couldn't pay me to listen to these. I genuinely would rather listen to the stock Samsung earbuds that came with my smartphone or a set of EarPods. These just don't sound good, lack clarity all over the spectrum, and have a horrible muddy bass.
Save your 7.11 (actually 7.52) and put it toward a better set of headphones or a nice hearty double double-double with animal fries at In-N-Out.
EDIT: To clarify, maybe these might punch above their wallet-friendly weight and into the $20-30 range. I'd probably agree with that. But honestly, that's not saying much as that entire price range is ripe with mediocrity and overpriced versions of the same OEM product. So sure, it's better than it's price indicates, but that doesn't mean it's actually any good still, because in my humble opinion, it's not. Koss' KSC75 remains the champion in that price category, period.
