HeadphoneAddict, I have a rather odd (stupid?) question & request for you.
Would you please check if the grey silicon tips can be used with the ES3X. I know they're meant to be custom IEMs, and you need to have ear impressions, but I'm considering getting them, and may have to wait for a while until to have impressions done, and so, I'd be using the grey tips in the meantime.
Use the grey tips with what?
