I had Big Ears custom speaker/earplugs made at the Tennessess Rally last July. They arrived in September, sent them back and a new set appeared in the mail yesterday.
My first test for these is to turn the television on with loud volume output. When I put in regular disposable earplugs, the sound virtually disappears. Bliss.
When I put in the Big Ear speaker/plug, I repeat the same test, same tv volume with no Ipod attached. The volume is only very, very slightly muffled; hardly noticeable. If they don't block external noise in the house, I expect that they won't give me much protection from wind noise at speed. Hence, not very practical for riding.
If you have custom made earplugs/speakers, do they actually block noise, even without music being connected?
I will be contacting Big Ear again about my problem with their product.
I had heard good things about the Big Ear product and therefore bought from them. So far I am disappointed.
