With second new hip (8-2)

I believe the answer is:

switched-on

'hip' is the definition.
(switched-on can mean hip or trendy)

'with second new' is the wordplay.
'new' indicates anagramming the letters.
'with'+'second'='withsecond'
'withsecond' anagrammed gives 'SWITCHED-ON'.

(Another definition for switched-on that I've seen is " Aware, up to date".)

I've seen this clue in The Times.
