Costco Kirkland Signature 8.0 Comparison | Hearing Aids Review.

The 8.0 is also similar to the Rexton Emerald 8C.

The Costco Kirkland Signature 8.0 hearing aid was released in February 2018. For more information regarding the release of the KS 8.0 check out this post on Hearing Health & Technology Matters: https://hearinghealthmatters.org/blog/2018/costco-kirkland-signature-8-hearing-aid-mfi-sale-price-1599/

Getting your hands on a pair of Costco Kirkland Signature 8.0 hearing aids is sometimes easier said than done. At Costcos throughout the greater Phoenix area, the wait list to be seen can be months. So for the purpose of this video, we are comparing the Signature 8.0 with it’s closest counterpart the Signia 7Nx devices.

You can see the specification sheets for both devices here: Signia – https://www.signia-pro.com/wp-content/uploads/sites/74/2017/11/Signia-Nx_detailed-feature-table_2018-02.pdf Kirkland Signature 8.0 – file:///C:/Users/Clifford%20R.%20Olson/Downloads/Kirkland%20Signature%208.0.pdf

In terms of form factor, both devices look nearly identical. They both use size 312 batteries, have a rocker switch for volume and program adjustment, and both use identical receivers that can be outfit with custom ear molds if necessary.

Let’s take a look at the core features:
1. Both have 48 channels
2. Both have 20 adjustment handles for programming
3. Both have access to 6 program slots
4. Both can connect directly to an iPhone for streaming
5. Both can connect to Android without streaming
6. Both have Own Voice Processing, they just call it different things.

This is where things get a little more complicated. We know the Kirkland Signature 8.0 hearing aid is a defeatured version of the Signia and Rexton devices, but it can be confusing on which features have been limited or removed.

For instance, how good is the Noise Management feature? Signia devices have Speech & Noise Management with 7 adjustment steps, Sound Smoothing with 3 adjustment steps, and Directional Speech Enhancement with 3 adjustment steps. In the Kirkland Signature 8.0 devices, it only indicates that Noise Management is available, and that it has Sound Smoothing with 3 adjustment steps.

How about Feedback Cancellation? Signia’s feedback cancellation is really good, but is the level of feedback cancellation in the Kirklands the same? The spec sheet tells us it is available, but it is impossible to tell if it is the same.

The Kirkland Signature 8.0 Spec sheet doesn’t tell us how high the Input dynamic range is in the device. The Signia Nx devices have an input dynamic range of 113dB. Why is this important? Because the higher the input dynamic range the better. Ultimately, it helps you hear better in background noise. It us unknown if the Kirkland Signature 8.0 hearing aids has as high of an IDR.

There are a few things that we know have been removed from the Costco Kirkland Signature 8.0 hearing aids and first is the Tinnitus Noise Notch Therapy and tinnitus masking features. In fact, no hearing aids sold at Costco have tinnitus features. So if you have tinnitus, Costco hearing aids probably aren’t for you.

The second thing that differs is the bandwidth. Signia Nx devices have a bandwidth out to 12,000 and the Costco Kirkland Signature 8.0 have out to 10,000. Since speech clarity resides in the high-frequencies, the higher the bandwidth, the better.

Ultimately, Costco Kirkland Signature 8.0 hearing aids are good devices. They are similar to Signia 7Nx devices but not identical.

Just remember, it does not matter how good your hearing aids are unless they are fit, programmed, and serviced correctly by your hearing care provider. This is true at Costco, an independent audiology clinic, or an ENT clinic. So before buying hearing aids anywhere, make sure you do your homework on the provider at that clinic.

You state that we must know if the technician knows what he/she is doing. How does one find that out?

Chelsey Michaud says:

I am a ‘Costco’ audiologist, and can confirm that the adjustment steps for noise management and sound smoothing are the same. Overall, clients have found benefits with the noise management programming (of course, this would be depend on their individual ability to process noise (we test the QuickSin to get an approximate idea). Additionally, the feedback manager works fairly well, as long as the appropriate coupling is selected for the user’s hearing loss.

All in all, I would say I have been pleased with the KS08, and do strongly agree that having the right audiologist to program the hearing aids and provide support/counselling will lead to much more success, than the level of technology in the hearing aids alone.

Arturo Benedetti says:

I Appreciate the attempt to evaluate but you cant do an honest assessment if you do not have the actual product. You can only compare specs from a cut sheet & best guestimates from your personal knowledge-base. Disappointed you did not have the product to assess.
I would not write an evaluation of electronics without personally having the actual product.

no mention of the price on the 7nX hmmm…
also please note, when i went to an independent hearing place, they charged me $2500 for a mid range hearing aid! so i took advantage of the money back guarantee and returned them and went to COSTCO, and got a top of the line model for only $1249 !!!
there was a great article on the hearing aid racket on cbs a few months back, a great read!

Richard Johnson says:

I need a hearing aid wich I know the ENT is going to tell me this via the audiologist I’m a poor working man can’t afford The amazing prices that was quoted to me do you recommend used hearing aids like purchase on Ebay or Amazon

Can you mute the microphone when paired to an iPhone?

Armando Dilello says:

In your Eargo review at 7:50 you correctly state that today’s hearing aid technology is unable to put out meaningful amplification past 7K, yet in this review at 4:15 you list it as a defeature against the Kirkland Signature 8.0 that the marketing/spec sheet indicates up to 10k instead of the 12k of Signia product. Care to explain?

John Boardman says:

Thank you Dr Cliff for an honest assessment and taking the time to give us information that can be used to make an informed decision on such an important matter.

Joel Pendleton says:

Costco’s biggest downfall is locking their devices so other audiologists cannot enter them to adjust anything. I bought Resound Linx for a great price thinking I could buy them at Costco then fine tune them at my normal audi clinic. You can’t, only Costco can access them and tune them and unfortunately Costco Audi’s at my location are horrendous.

Jim Davis says:

Great Review. Do you think signa aid are better than the New Phonak Marvel. I don’t dispense seaman’s products at this time. Thanks.
