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.
"Innovation has a new name: Cellion. It is the first hearing aid in the world to contain a lithium-ion power cell that can be charged contact-free. At the same time, it is based on our innovative and highly acclaimed primax platform. The future certainly has a lot more in store for us. We are working on it every day. But at this point, we can say with full conviction: You can't get more innovative than this."
"Learn how to charge your Signia Cellion hearing aids. The battery lasts for a particularly long time – up to two days* after a four hour charge and for at least seven hours after just 30 minutes express charging. This works contact-free in our new charging dock. You can either connect it directly to the supply mains or, for example, to a USB car adapter or the USB power supply of your smartphone. This is particularly useful when traveling."
