A listener rushed out, transfixed! (7)

I believe the answer is:

speared

'transfixed' is the definition.
(spearing is a kind of transfixing)

'a listener rushed out' is the wordplay.
'a listener' becomes 'ear' (body part which hears or listens).
'rushed' becomes 'sped' ('speed' can be a synonym of 'rush').
'out' is an insertion indicator.
'ear' put into 'sped' is 'SPEARED'.

(Another definition for speared that I've seen is " hit by javelin maybe!".)

I've seen this clue in the Evening Standard.
