KukoCLI understand that. However, at this price point, it's not like they're going to be good enough to take advantage of the open back design. Lack of isolation just makes cheap ear buds worse.
dafolzeyTechnically, they're not open back.
The dynamic-driver sits in a semi-hollow shell which adds some pretty stellar open sound-stage.
Also they sit just outside the earcanal which gives them no sound isolation and adds an airiness sound to them, if that makes sense.
What makes these better than earbuds (not iems btw) found at pharmacy/dollar stores is they're build quality is stellar for the price. Strong magnet for the driver, smooth chassis with no protruding plastic that can scratch the ear and a pretty good rubberized cable, not that cheap hard-plastic or "braided" cables.
I'm not trying to convert you. I'm just stating why 22,000+ people have purchased these from Massdrop. I may be biased because I own a bunch of monks but these cannot be compared to CVS trash. I've also tried numerous other earbud brands (philips, sony, etc.) and they don't even compare to VE Clan's product.
