Costco Kirkland Signature 10.0 (Product Information)

If you want a spare pair of KS9, I’d jump on it. However, you can send your current pair in as they approach the end of their 3 year warranty and get a new pair that way. Who knows what available when they finally wear out.

Anyone know why they included the T-coil? Is there that much demand for it these days?

OK, clarificaton on dimensions. They seem to measure width differently than I do. I think they measure from the outside of the bottom to the inside of the top. Since they’re kind of built on a diagonal I think this gives the impression that they’re bulkier. Stated dimensions for my 312T are 1.14 in x .46 in x .29 in So rechargeables are .06 x .04 x. 02 inches bigger. So yes, they are bigger, but not dramatically so. If you want super tiny hearing aids, they’re likely not for you, but in reality they are pretty small. Go look at them in person to really get an idea of what they’re like. Numbers only go so far.

Thank you MDB for the quick reply. That is disappointing.

Does anyone have an idea what the recharging options are? It looks like the charging case requires an AC connection. Is there any option for recharging without AC or a DC adapter? Like a case with built-in battery, or a USB connector so I could use a power bank?

Always confirm this type of stuff, but going from memory the charger uses micro usb so should be able to charge with a power bank. Phonak also makes a Power Pack https://www.phonakpro.com/content/dam/phonakpro/gc_hq/en/products_solutions/hearing_aid/audeo_marvel/documents/quick_guide_phonak_power_pack_029-1092.pdf44

It’s possible Costco will come out with a second KS10 model later.
The original KS9 was not T-Coil. Costco came out with a second KS9 model with T-Coil at a later date.

I would not bet on this but it is possible.

My understanding is that they are mic ports and that Phonak put considerable effort into design to reduce wind noise. That’s one downside of the KS9 and 10 versions. I think it likely that the internals are the same, but this type of info isn’t readily available.

Now I have a dilemma - I love my KS9s and do not want to consider life without them, but I really don’t want rechargeables. To me it would be like having range anxiety with an electric car! So, I wonder how long the KS9 will still be on sale, and should I fork out now for a spare pair before they are discontinued. Or, might Costco come out with a 312 version of the KS10…decisions decisions…

Couldn’t agree more.

There was a post in another thread that Costco is not selling KS9 anymore.

Kirkland Signature 9.0 from Costco vs TruHearing

I was told yesterday that they are no longer allowed to sell the KS9 model.

Thanks MDB. Whatever they are, I can say that the P90s have been much better in wind for me, as compared to my old Brio2s which share the mic layout of the KS10s.

Another improvement perhaps related to mic placement is it’s been much easier to recognize the directionality of and distance to human speakers. Not so much initially with bird calls, but that’s largely resolved itself on its own.

Ah now that’s a pity - I’d better get in contact with my UK branch ASAP & see if they could slip in a final KS9 order for me.

Can you do this? I mean - even if there is nothing wrong with them? Get a replacement set for free?

Pretty standard to send has back near end of wty to get “checked” out and get new ones back. Really important with rechargeables.

That’s news to me! Thanks
