What really drives me nuts about these Bluetooth wireless IEM’s on Banggood, is that they all seem to be “about the same.” Each listing looks very similar to the next, with some variation in pricing, but specifications will be inconsistent with amount of info provided, while info that is indicated looks similar. It makes me wonder if there’s just ONE technology at hand being repacked multiple times in slightly different casings. Flood the market with all these to keep the consumer confused so they just go ahead and impulsively buy what they THINK is the best choice, when in reality, it’s all the same stuff.
