Frequently Asked Questions
Need Help? We've got you covered!
I have severe hearing loss. Will these work for me?
How to avoid whistling?
Whistling is common in small amplifier and is known as 'feedback'.
It is caused by amplified sound leaving the ear and receiving back into the microphone and being re-amplified. The following tips will help reduce the effect of feedback/whistle noise:
1. Lower the volume.
Keep volume at lower setting before inserting the instrument in your ear.
2. Secure instrument fitted position
Feedback/whistling noise will stop when the instrument is best fitted/sealed in the ear with the best fitted dome size.
3. Clear the ear canal of wax or debris.
Seek your hearing care provider for excessive wax built-up
4. Replace the dome or tubing.
Change new dome with a better fitted size.
Make sure the tubing is not broken or torn.
Do I need to have a hearing test before purchasing these hearing aids?
No. After connecting the hearing aids with our free app SOUNDWEAR, you can complete a hearing profile in the app. Then tap "Fit with this Result" to customize based on your hearing loss.
If you already have an audiogram, you can input your audiogram by dragging and moving the dots in the audiogram chart, so as to fit your unique hearing needs.
Are the domes available in different sizes?
Each order comes with 7 pairs of domes:
2 pair of white double layer domes: S(10mm), M(12mm)

They are so easy to wear and set up. My dad has a moderate hearing loss and he can now hear the TV at low volume. He says it sounds even better than the old $700 aids. Highly recommended.
M
I did a lot of research on OTC hearing aids before ordering these from Wellue. I need these to be USA made because in my experience chips determine sound quality. I asked their customer service and after knowing that the chips were onsemi I ordered these immediately. I'm glad my hearing was clear with them. They have worked even better than my old pair that cost $1000.
C
The hearing aids is lightweight, I forget they're in sometimes. I like that I can adjust each hearing aid from my cell phone. You can have each ear adjusted to your exact needs. Once they're set, you don't have to mess with them, but you can retune them if your needs change.

I have moderate hearing loss and these hearing aids have changed my life! They are so easy to use. I follow the instructions on the app and they fit my hearing when complete hearing profile. I charge them overnight and they are ready to use all day. I can hear better now and no longer have to ask people to repeat what they said. Also love the different environment program mode feature.

I've been struggling with moderate hearing loss, finding it challenging to hear others. The cost of traditional hearing aids was prohibitive, prompting me to explore alternatives. After thorough research, I came across these hearing aids, which seemed to offer an excellent solution. These hearing aids are FDA approved with reasonable price. Since using them, I've noticed a significant improvement in amplifying sounds, making my daily interactions much clearer. Worth every penny!
M
It was great! Purchased these for my grandmother, and the improvement has been remarkable. Communication has become incredibly easy thanks to these hearing aids. The app instructions were clear and straightforward. I set for her and now she can hear again. Thank you Wellue.
K
They arrived quickly and in good condition, and the hearing quality is exceptional! I'm amazed at how clear these hearing aids perform. They surpass the performance of my previous $1000 set. Easy to set up and use. I particularly appreciate the design where I can simply touch a button on the top to adjust the volume while wearing them.
s
These were a Christmas gift for my mom, and she's thrilled! Clear sound and no more raising our voices. Adjusted settings using her audiogram on the app, now it's a custom fit. Easy to adjust volume and switch listening programs. An excellent choice for parents!
o
As someone new to hearing aids, these were a relief. I've been using these hearing aids for weeks, and they've been amazing. I'm impressed by the sound quality. They're comfortable to wear, and the Bluetooth app is super convenient. A definite improvement in my quality of life. Worth every penny!
L
The setup and charging were quite simple. I highly recommend putting it in your ear first and then turning it on to avoid feedback. I wore them a few hours for the first few days. There's an adjustment period for fit, but patience pays off. Now I can hear clearly and watch TV without having to turn up the volume to super loud levels. Battery life has been reliable. For those seeking affordable and effective OTC hearing aids, these are a fantastic choice!
