My only worry is really that the previous user did something that would weaken the band in the long-term. Ive used both th e S-500 (Active) and T-500 (regular). But then, earphones arent supposed to withstand that abuse. It is plastic ear cups , but the headband is Pleather wrapped metal. or anywhere else! The inside of the box has sticky spots where someone spilled soda in it. My trusted vet uses this to clean my pets ears. My friends tell me the voice chat is clear and sounds good. Spot on. But after a month or so of regular wear, they wear out on the bottoms.
