Opinons on Siemens Orion 2 vs Costco Kirkland 4.0

I’ve been using Kirkland 4 for a bit over two years and am generally satisfied. My new insurance will cover new hearing aids, but only through HearUSA. The “best” they’ll cover without any out-of-pocket expense are the Siemens Orion 2. How will the sound quality compare to my Costco Kirkland 4.0? The Orion 2 won’t take rechargeable batteries, but does come with an app to turn my phone into a remote. But I’m really interested in whether the sound quality will be better. Thanks.

Well, if they are “free”, you’d at least have a backup pair. You could then try Costco’s trial which is now 180 days.
