Hmmm. We need to be careful and sensitive in responding to a post, lest we portray ourselves in a manner un-befitting. You have no idea if this person has a medical condition whereby he may be partially deaf in one ear or has tinnitus worse in one ear. Yet you have chosen to advice him to go check his hearing before he damages them. I will suggest if there's no direct answer to a specific gadget-related question, one avoids going on a tangent and offering advice, especially one that is medical in nature. Just my two cents.
