Ross

I believe the answer is:

mouse

I'm a little stuck... Click here to teach me more about this clue!

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

'quiet piece of' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
The remaining letters 'muse' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for mouse that I've seen before include "computer equipment" , "Small rodent - computer device" , "computer operator" , "Domestic rodent" , "PC device" .)

I've seen this clue in the Evening Standard.
