re: being concerned that you didn’t try others besides the Jabras. It’s common with the first pair of aids to want to try several different models, and with four brands to choose from in the current Costco lineup, that is an advantage of Costco compared to many private audiologists. But personally, as someone who started with a private audiologist and tried three different makes with two-week at-home trials, I got confused by it. With two pairs, you’ll have a preference. Three or more can be confusing. If there’s one standout pair among three or four you try, then sure, that makes sense. But often you’ll be thinking, gee, in some ways I liked #2 better than #3, and then in other ways it was the other way around, and now I forget what #1 sounded like.
I have a pair of Jabras on order from Costco right now. That was the only one I trialed in the store, and it was the one the tech said thought would be the best fit for my moderate-to-severe loss, and it just felt right to both of us. I’m in a different place though, with 16 years of experience wearing aids. I will say that Costco isn’t known as many others are for favoring one model over another for reasons such as sales commissions, bonuses, or promotions. Generally their advice will be very sound advice. And Costco’s almost unbeatable 6-month return for refund-or-exchange policy is exceptionally generous.
The quality of the fitting and the service you get from the tech can overcome minor differences in first impressions among models. Prescription eyeglasses are generally plug-n-play; after a 5-minute store adjustment, you’re probably good to go for several years. Hearing aids, especially for first-time wearers, benefit from several visits of fine tuning to the settings. They’ll usually sound much better after you go through that process than in the in-store trial.
It doesn’t sound like you ordered the Jabras yet. If you did order the Jabras, I’d advise you to go with what you ordered and see if it works out, as it likely will. If you didn’t order, go with your gut: if you really want to try one or two different models before deciding, it’s not an unreasonable request. Don’t overthink it though; a few patients do and never pull the trigger.
