Answer

Josh has a Brighton accent.

Ollie has a London accent (not Cockney).

Answer

I know they are from the UK, but I'm interested with more precise answer. I can hear Ollie's is different to Josh's.

Answer

Thank you for your answer!

Answer

They sound like they're from England to me.  (Someone from England could tell you the region.)

Corrections:  I'm interested IN that, but I'm not a native English speaker so I can't tell.  Can anyone help me with that?
