Sorry for the slow reply. I've looked and there doesn't seem to be any way to tell.
I've used them regularly for about 5 or 6 years now and the paint is wearing off. The only readable markings are the [L] and [R] indications for which goes in which year.
Nickel/neodynium bass drivers, quite large and chunky compared to cheaper Sony 'phones. The cables go into a separate fat little cylinder to which the earbud itself is permanently attached at a fixed angle.
However, they're not noticeable in the ear at all and they're very comfy to wear.
These are listed at £40 now but before the recent burst of inflation I think about half that is plausible.
