Are there any differences between the Resound hearing aids sold at Costco and other Resound hearing aids?

The ReSound Cala is essentially the same as the ReSound Linx2-9 product, with the exception of the absence of the tinnitus management feature.  Costco generally gets its products from the manufacturers about 12-18 months later than independent offices do (i.e. they are older products).  ReSound will likely release a new product within the next six months for regular accounts that Costco would have access to some time in 2018.  Regarding the tinnitus management feature, Costco specifies to the manufacturers that they do not want tinnitus features in their products since tinnitus patients require significantly higher levels of service than traditional patients with hearing loss alone.

Based on a visual comparison, the ReSound Cala is the same as ReSound LiNX2. Unfortunately, ReSound doesn't allow independent providers access to the technical specifications of their Costco line of hearing aids. In fact, Costco purchased hearing aids are software "locked" and can only be adjusted at Costco hearing aid locations. Typically, Costco hearing aids are a hyrbid level of technology (between low-to-mid or mid-to-high) and at least one generatation behind the latest technology. I am not sure if this is currently the case with ReSound. 

i recently had a patient come to my office.  She had been given a set of ReSound hearing aids from a friend whose family member had purchased the aids and then passed away.  they were clearly resound aids but i could NOT read them at all - wirelessly or hardwired.  She called her out of state relative to find out where the aids were purchased and they had been bought at Costco.

There are differences, Resound has maintained a “policy” of keeping their offerings to Costco one generation behind what is currently available.

There are obvious other differences between the patient care and experience but I hope this helps answer your question!

As a side note, Costco is going to stop carrying ReSound hearing aids soon and go to all Rexton (Sivantos) per this article.

So you might want to ask and make sure they will continue to service the ReSound hearing aids for many years to come.
