I think I hear one instead of on?
Maybe there's something a little bit off with the female voice... the male one sounds fine to me. Anyway, even if you hear 'one', you should discard it as "nosi" definitely doesn't suit it grammatically.

He wears a wide pair of trousers
what about "baggy" pants?
Or 'flared trousers'?
"He is wearing wide pants" is not acceptable?
why not pants
What are wide pants?
Those that do not really touch the skin too much?
That is accepted.
