I have used the unit three times and have noticed that my ears hurt aftewards. Could this be causing hearing loss? Why would my ears hurt?

This device produces high-intensity ultrasonic vibrations. The word "ultrasonic" is used to describe vibrations above the range of human hearing (~20kHz, or 20,000 vibrations per second). The Labelle scrubber operates just outside this range at 24kHz, which is why you can't hear it, but if you have a cat or a dog, they can, and if they're close, it's probably quite painful to them. Even though you can't hear it, there are parts of your ear that are still affected by this frequency. Your tympanic membrane (eardrum) will probably be vibrating like crazy when you're using this thing, which is likely the source of your pain. There are some studies that suggest that ultrasonic devices like this can, in fact cause some frequency-specific hearing loss in audible frequencies, but the data are not definitive and are limited to cases of long-term, frequent exposure (daily use of ultrasonic dental instruments for example). I suspect this scrubber produces a similar sound pressure level to dental instruments, but you're probably not using it frequently enough to be worrisome. You can try using earplugs to help prevent the ear pain, but with this thing pressed against your face you might be getting most of the vibrations via bone conductance which would not be affected by the earplugs (especially on your cheekbones and forehead). Most importantly, keep your pets away while you use this thing; it's basically a high-powered dog whistle.

Mine did the same thing. I only kept this a week due to the poor sound quality. However, the problem seemed to go away after charging the unit a few times.

I have two devices that I use in alternation, one ear, then the other ear. I choose not to use both ear pieces at the same time due to the sound amplification beings "too loud". For me at least. But the devices work wonderfully well in amplifying high tone sounds and words, which is what I was lacking. Tom.

I have had mine for several years, and no problems whatsoever. It sounds like yours is defective and you should see about having it exchanged.

I found my set to be very balanced in sound. In my old unit, the bass distorted at high volume. This unit appears to balance the bass with the other sounds. Could your unit be defective?

Sounds like a faulty unit, my last one only lasted a couple of months. It's just a cheap fun thing so I figured I would just replace them as they gave out... Since it came that way though I would say return it for a replacement.

The unit could be bad. The first i bought was bad, it never had sound. I returned it and the second one works normal.

I haven't occurred any problems with my Panasonic HC. Are you sure those are the correct headphones to use with this device? Also, you may have a defective piece of equipment, if the speakers are malfunctioning. I know this wasn't a big help to you, but I hope you can figure out the problem, because it really is a state-of-the art piece of equipment.

To be very honest, I have not used this unit in quite some time. I am still trying to figure out HOW this damn thing works. I know all local frequencies by heart, but setting up which where who and how..... just to get the thing to scan is less than impossible. I have used other brands in the past with excellent results. I think this was a mistake. But to answer your question, some emergency departments have the burst of "static" sounding stuff at the end of each transmission. You might try turning down the SQUELCH. This may not help but I tried.

I use mine about a week or a little longer, but I have zero problems with ear infections or much earwax. After I first insert them, I can feel & hear the foam expanding. When I notice that the foam isn't expanding as vigorously as it did at first, I know they're not going to block noise as well, and it's time to replace with a new pair. Oddly, to me, it seems like one plug in the pair usually fails first; I guess I'd have expected they would both go about the same time. I strongly agree with those who say don't wash them; that was an accident that did not go well.

Not sure what the problem is, I'd return it to the store for another one. I like mine, plenty of sound for the size...

If you are using the 3.5mm AUX plug, I would check that it is secure. If you are using the radio modulator, then really likely a bad unit since it would not suffer a single channel issue like AUX. Check on another blue tooth stereo to test playback and eliminate your source as the problem.

I have had no problems with my Plantronic head set. Maybe you do not have it situated in your ear just right. I know I had that problem at first, then I realized I needed to swivel the little torpedo shaped ear piece and point it into my ear.

Loud noise (military service) damaged my high frequency hearing and speech is difficult to understand if mixed with background noise. I was told nothing will completely restore the loss and I'm sure other peoplehave different problems and symptoms. The life ear device is a greathelp for me, however, it did take a little while to get comfortable with.I have found there is no problem with wearing it with my right ear only.When driving, it allows me to understand my wife sitting on my right much better. If you have complete loss of hearing in one ear, I see no reason the wear the device for that ear. If you buy the pair that givesyou a spare at reduced price. Hope this helps.

I had the same problem. It seems single wire headsets do this repeatedly. The only set I still have that functions is a two into one wire headset that I paid 20 bucks for. I won't be buying another one of these.

You know, my original thought when I saw your question was,"I don't know." Then I started thinking my ears used to ring bad at times, and I haven't noticed it lately. I still have to say, of all the non Rx units Ibe used, it is STILL the best I've bought... Hope that helps.
