This listing is for 1 brand new never used Phonak Marvel speaker / Receiver.

Side: Right

Length: Size 0

Strength: Medium Power (M).

This receiver is only for Phonak Marvel hearing aids. They are NOT backwards compatible to older models as they have a 3 prong connection. Likewise older speakers with a 2 prong connection will not work with the new Marvel line of hearing aids.These new speakers are an upgrade to the older 2 prong connection. They have 3 different strengths (Standard, Medium and Power) and they use 4 different types of domes (Cap, Open, Vented and Power) in 3 different sizes (Small, Medium and Large) all of which can be found in our eBay store.
