I bought new headphones, Sony XM5, they work GREAT! They block a little noise if you not listening to music or watching tv online. For over a year, I been having trouble in one ear, I have ear medicine. My ear is more than good now, I can hear way more, now I been having more sensory issues. Anyway, how can I be more careful with my headphones since it cost over $300? It came with a case, I been puting it in it case, I don't know if I will forget one day, I already dropped it once.
