The Crown pub has single, small cans (10)

Ross

I believe the answer is:

headphones

'cans' is the definition.
(I've seen this before)

'the crown pub has single small' is the wordplay.
'the crown' becomes 'head'.
'pub' becomes 'ph' (public house).
'has' is a charade indicator (letters next to each other).
'single' becomes 'one' (I've seen this before).
'small' becomes 's' (abbreviation - e.g. clothes size).
'head'+'ph'+'one'+'s'='HEADPHONES'

(Another definition for headphones that I've seen is " cans".)

I've seen this clue in The Independent.
