I’m looking at switching from the Rexton BiCore that I love, to the Rexton Reach. The fitter has tried all kinds of domes and there is feedback. Could they be defective? They say no. Should i try on another pair at a different Coxtco ? Thank you very much.

Are they using the same prescription for the Reach pair as for the Bi-Corss? I just made the same switch and have not had a problem with feedback. I am using . Are you?

This is where seeing your is helpful. (Top of page, click on FORUM, click on My Hearing Tests) Sounds like you need a more closed fit: Depending on your audiogram : , power dome or custom mold. If they’ve tried multiple domes, sounds like a custom mold would be appropriate, but again seeing your audiogram would be helpful. Have they changed out the ? Sometimes a bit of wax can cause feedback.

If they tried different types of domes, then I would suspect the hearing aid is pulling on the receiver inside of your ear, creating a leak. This may be a case where the new hearing aid is setting on your ears differently. Using custom molds may help.

Yes, it’s possible the hearing aid is defective. Take the hearing aid to a different Costco to get a second opinion.

Note, if you return the hearing aid and go to another Costco, they are going to know and may deny a new hearing aid of the same brand.

So I would go to another Costco to see what they say, and try custom molds if they can’t get the feedback under control.

The first thing is get a set of custom molds made to try, as you’ve already tried all the different domes, so time for custom molds which will be a better fit and almost eliminate feedback, the most obvious and common reason is sound leakage which is quite common with domes, why your audiologist hasn’t suggested molds is a bit unusual ( well unless your loss is mild to moderate) it won’t be the , for both to have the same defect would be most unlikely, it’s a fit up issue I’d think, but do make sure your ears are clear of any wax build up (another common reason for feedback when there shouldn’t be )

The Rexton Reach improved over the Rexton BiCore like the Signia Pure Charge&Go 7iX improved over the 7AX. I read many reviews about that improvement and decided it was worth waiting for Costco to start selling the Rexton Reach, which I bought earlier this week.

The workflow changed with the Rexton Reach. It used to be that when you run critical gain (their feedback manager), it would check the box that says Limit gain to individual critical gain automatically. Now you have to click it yourself. This change will likely catch fitters off guard.

If the gain exceeds the critical gain, they may have feedback. Also if the individual critical gain isn’t calibrated, it will use statistical critical gain which is going to be random chance of whether you fit the statistics.

Overall, Reach has been fantastic so far. The one-vent dome that they inherited from Widex is versatile and a great alternative to a tulip dome or a vented sleeve. Minimal occlusion with decent isolation and streaming quality. That and the own voice trainer, which Rexton now suggests should be run for every person.

I was getting constant feedback with my Phonak Kirkland 10’s. Turned out I had earwax buildup that was so hard it wouldn’t flush out. I went to an who removed the wax from my ears, and all the feedback went away.

yes. Ear wax build up will cause feed back in hearing aids. I know this from long experience, confirmed by my specialist.
