Cerushield

Bought for Phonak Audeo M90-R hearing aids, these are necessary for prevention of dust, moisture, earwax or anything blocking the tube, any of which would prevent hearing. They work and this seller provides them at great value and shipped quickly. Recommend!

Good value

What can you say about Cerushield filters? These are not some sort of optional extra that you may or may not choose to buy, they are only useful for one thing and if you too have Phonak Marvel hearing aids with in-ear buds then you'll need them and at less than four quid you can't really argue with the price (after all it's less than the price of a pint in my local).But, and there is always a but, but this all seems to be a bit over-designed and under-engineered. The process for replacing the guards is a bit fiddly, especially if you can't see too well and/or your fingers aren't as agile as they once were and the dispenser disc requires a combination of knack and brute force to rotate [but it's a beautiful design concept] and that's why it's only four stars from me and time for a rethink from Phonak I think.

Hard of hearing

Once you've bought a phonak heraring aid you are left with no option but to use these. Cheaper than Boots, where I bought my aids, but essentially not that easy to use, wherver you buy them!

Bought every colour!

As I have recently changed my hearing aids now have to use these wax guards. Easy to use and does the job!

Essential tool for bi-monthly maintenence of my new Phonax Paradise hearing aids. Easy to operate and reasonably priced comparably.
