The truth about Dyson "Air Purifying" Headphones...

This video is not sponsored. Aint nobody got money for a 500 dollar vacuum. Everybody has money for a JerryRig Knife though. Grab your new LTT Orange edition before we run out! Canada is giving the Tech Tip's fam a hard time at the border but their knives will be back in stock asap. Dyson is rolling out their new line of air purifying headphones. Pretty interesting technology! However... is it any good? Does overpressure air purification even do anything? NASA, Tesla, and 3M seem to think so.
