I bought a pair of Kyonon 8x30 Porro binoculars on eBay to keep me going while I search for the ones. The name sounds Japanese(?) but the two descriptive terms on the binoculars themselves are in German. Weitwinkel, meaning wide field (8°) and Vergütet, which I think means Coated(?), though the lenses seem colourless. Does anyone know anything about these?
I bought them because they looked in good condition, looked identical to some Pentax Porros I've seen, and were cheap. They seem pretty good; light, sharp and bright. Well worth the money. The image quality falls off pretty badly near the edge, but that doesn't matter the way I use them. Early impressions are that they do much worse against the light, even compared to my wife's 7x21 compacts, but for £15 I wasn't expecting miracles.
The only things I'd like to be able to improve are the eyecups. They're the rubber, fold-down kind, but seem pretty hard and unyielding. Is there something that I can treat the rubber with to make it softer and more face-friendly?

The rubber won't fold back? I have some porros that are uncomfortable, I fold the rubber back and rest them on my face above the eye sort of near the eye brow. These are not made to use with glasses, and I do not use glasses with them. Not the ideal way to hold it, but it is more comfortable.
You can also cut the rubber rims off, but you can't put them back on.
