I'm not in the City of Lights, rather in a more remote place actually.
My daughters arrived today
Extremely comfortable to wear. The latch to take them off is so convenient!!! A very sophisticated sound signature, for me definitely more focus than the 334.........
Extremely happy with purchase and so are my daughters, seeing their names on the earpieces.
