Perhaps consider a radio interference test, I find that turning on the microwave really hammers some earbuds, and not so much others, especially at the range of being a couple rooms away. This is one area where the jlab shines, I can microwave and not have my podcast interrupted, others like skullcandy are less resiliant, while the jib trues have the same range they start to stutter when near the microwave, the anc fuels just get wiped out completely, haylou gt6 along with this jlab weather the interference no problem. Goes to show price isn’t perfectly correlated to antenna design.
