Waterproof Hearing Aids:

If you are pretty deaf like me you can’t do much well in the outdoors without waterproof hearing aids. Unfortunately Siemens (now Signia) have stopped production of the Aquaris model of waterproof hearing aids, so I can no longer buy a spare (though I will be looking out on eBay – Gumtree is better for this)

They have two new models which are mildly water proof 1P67: the Motion and the Cellion. These new models also have updated hearing technology, so if you are after a new pair of hearing aids you will be hearing better than ever with them! They even claim you will hear better than folk with normal hearing!



(Pictured above Signia Motion – they also take the ultra-thin ‘Life Tubes’)

However, I have spoken to Signia/Siemens at length and they say neither of these products will stand being submerged (particularly the receiver in canal (RIC) of the Cellion, so I can’t imagine what this rating is all about, The Motion is likely to fare better than the Cellion – and should withstand sweat and some light rain, but will not stand being submerged, they say – though it will probably dry out and start working again (and would be covered by a warranty) There is nothing now which is suitable for swimming or canoeing (ie when you fall out, which you always do sometime!) The best you can do is maybe source a pair of second – hand Aquaris. Good luck with that. You will have competition.

Below is what the IP stuff is (supposed to be) all about:

IP (Ingress Protection) ratings IP67 & IP68:

First digit: Solid particle protection:

6 Dust tight No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.


Second digit: Liquid ingress protection:


7 Immersion, up to 1 m depth Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). Test duration: 30 minutes – ref IEC 60529, table 8.

Tested with the lowest point of the enclosure 1000 mm below the surface of the water, or the highest point 150 mm below the surface, whichever is deeper.

8 Immersion, 1 m or more depth The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and/or duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion. Test duration: Agreement with Manufacturer

Depth specified by manufacturer, generally up to 3 m

The rechargeable nature of the Cellion (and the ‘soluble RIC!) means that I would have to carry a charger and a power source (as compared with two spare hearing aid batteries – perhaps), so they would increase my pack weight by perhaps 200 grams or more. Unacceptable. I will be going with the IP67 ‘Motion’ model when the time comes to update my Aquatris ones – unless I can find something better! They are available here from US$1195 ea –Nov 2017: http://www.thehearingclub.com/SiemensSignia-MOTION-and-Orion-2-BTE-Models_c_121.html

Siemens claimed their Motion binax was IP67 waterproof to 1 metre for 30 minutes: https://www.bestsoundtechnology.com/pro/siemens-hearing-product-portfolio/binax/motion/

PS: I managed to buy a second hand model of the Motion Binax on Gumtree for A$250. This is wonderful news for me.
