Headset-Get what you pay for
eBay eBay eBay.......
Something like a headset you should not skimp on. They give your hearing protection, improve communication (safety) and comfort improves enjoyment.
A bad cheap head set that breaks or has inferior performance is not a bargain.
Go to eBay and get the best head set you can. Research the main brands, Lightspeed, Peltor, D/C and so on. You don't have to get the top of the line to get a good head set, but these boys look like like el-chepo headsets. Even if you are just getting them as a spare for a passenger, go to eBay and get a good headset. There are always many on there. Know what they go for new and don't bid too much. Cheers George
