This is a pair of battery operated hearing aids that my dad no longer uses. They are behind the ear aids with receiver in the canal type. Uses the smaller of the two main battery style batteries. they work well but my dad went the rechargeable way. I believe they are Phonak brand but can only see the numbers inside the battery compartment of CE0453 and 17. you will most likely need to have them programed to your hearing loss. They are clean and ready to use other than the programming. Priced to sell quickly at $30
