Do speakers all sound different?

Something very strange happened today, for a couple of hours I noticed that my cellphone loudspeaker emits completely different tones than usual (darker tones and the cellphone is quieter than usual). At first I thought my speakers were broken, but my best friend had the same problem immediately afterwards. Same problem with his and my TV. Does my brother have his laptop too, and even my Nintendo Ds? Something is really fishy. Is it coincidentally because of the extreme snow today? I don't know that's happening for the very first time today, and there's nothing on the internet either.

Maybe it's your ears. Or you should take off your hat, it muffles the noises.

I just googled again, everything speaks for a sudden hearing loss.
