It's 32 ohms without any added circuitry so even though custom for Phonak, the driver may now have new home since Phonak is no longer a customer. I bet it measures about 22 ohms with a meter.smile.gif  I took a pair apart to find this driver, a Sonion 2354. Either version 1033 or maybe it was made the 33rd week of 2010.


I guess we're getting OT, but someone I knew threw a DC ohm meter across the PFE112's 2354 (driver only, no cables, etc.), and it read 5.2 ohms, so it's not a custom version... not quite sure how Phonak's getting the 32 ohm reading, but perhaps it has additional passive components in the... Y-split, hard strain relief, cable?

to be exact, what series of the Hippo amp that is the most suitable with the Hippo ProOne? (for getting the most hippo sound signature)
