About the Signia Cellion primax
Signia recently released Cellion primax, the world's most sophisticated inductive-charging rechargeable hearing aid. Cellion primax is technologically similar to Signia's Pure primax, but with the added benefit of rechargeability. Signia claims the Cellion primax can operate at least 24 hours, with unlimited audio streaming. If true, this places the Cellion primax in the lead (in terms of rechargeable battery longevity) against Phonak's new Audéo B-R rechargeable hearing aid. According to Signia, a 30-minute "powercharge" feature enables for more than seven hours of use. We're not sure if that 7 hours includes any audio streaming at this point.
Note: We've seen conflicting information about the IP rating for the Cellion primax (68 versus 67), so we're being conservative and assigning the lower of the two reported ratings.
