for the money they are good, only thing that I have found is that one ear seems slightly louder than the other which is throwing off the balance a bit and the microphone clip could be a bit tighter to stop it from swinging around which should be easy to sort out. apart from those bits I would say they are a good buy for the money
sad for me the adapter not fit my head enought but it suit the rail well . earmuff is good , sound amplified loud and clear than i expect .
