Test piece for earphones?

Hi all

I use Etymotic 6is ( among others) which have filters which eventually get clogged up and need replacing. Sometimes one side/channel goes pretty dead so easy to know and replace as necessary.

Last week though I noticed that the vocal in one of my favourites was slightly "to the left" - not much - and the right earpiece still working (@about 95%?) I replaced filter and all well again. But it set me thinking - is there any "test piece" or "tones " or something which can give early warning of this ?? I'm thinking of things like - a tone plays and voice says centered (!) then you get "2 metres left" or whatever!!!

Obviously this isnt a crucial issue at all (to me anyway) but I'm just intrigued if there's anything out there!

PS my own personal "test piece" is the opening of John Mayall's Blues from Laurel Canyon. A jet engine goes from far left across to far right - now if only it stopped every 10 metres and asked you to check your phones!!!! (LOL)

Stereophile used to have a test CD they gave out to magazine subscribers that did what you want. I have two of them...don't know where they are, though. You might email them or phone them to see if you can acquire one some way.

Since you are using the 6i, I think you might want to know that you can pull the filter out by your finger tips and clean the filters so you can save some money on the replacement. Just submerge the filters under some pharmacy grade peroxide solution (usually 5%) and wait for 15 minutes before rinsing them, than let it air dried and you got yourself a clean pair of filters.

A slightly belated thanks from me too regarding the filter cleaning idea!! It sounds slightly "fiddly" - but certainly worth a try (nothing to lose!!).

Thanks again to all.
Regards.
