If you are experiencing ear pain/infection, have had mastoid surgery,
currently wear ear tubes or have a perforated eardrum, please contact
a medical practitioner before using this product.

Our patented earpiece system was developed under the advisement of
our medical board consisting of Ear, Nose and Throat Specialists (ENT).
Our earbuds reach no deeper than the medically safe outer 1/3 portion
of the ear canal, or in other words, these earbuds reach no deeper than
the disposable foam earplugs that millions of industrial workers
use everyday.

During the shaping process, nothing ever touches the ear other than the
hermetically sealed bladder of the earpiece. The safety of the product
is thoroughly tested, including the strength of the bladder which can be
expanded to over 12 times the volume of silicone that is contained in the
fitting system. Sonomax has been using this in-ear expansion technology
in its custom-molded hearing protection over the last 10 years, and there
are now over 100,000 users of this technology in the form of the Sonomax
hearing protector.

We use only medical grade hypoallergenic silicone for our custom molded
earphones. It is the same silicone that is certified for use in medical
implants. You know your allergy history best, so if you are concerned, then
you should speak with your doctor regarding your allergies before you use
this product.

No, getting custom fitted earphones will not hurt at all. You may feel the expansion of
the earpiece in your ears for the first 30-45 seconds. It may feel strange
at first but don’t worry, it’s perfectly normal! As the earpiece takes on the
shape of your ear canal, you experience less and less noise from the outside
world coming in — some people describe it as a Zen experience.

If your custom earphones feel comfortable and seal your ear-canal so you are
listening at safe levels, you have a successful fit.

The ergonomically-shaped earloops provide maximum security for
maintaining the in-ear position and acoustic seal of your custom made earphones
during extremely active performance. The earloop is also beneficial in
attenuating sound of wire rubbing against clothing which is typically
experienced when the ear is occluded (acoustically sealed). The wire
noise is known as microphonics.

A snug seal will greatly enhance bass response, so be sure that your
eers™ custom molded earphones are properly positioned. Use lubricant and don’t be afraid
to give them that extra little rotate/wiggle and gentle push-in to get that
desired snug seal.
Most music players allow you to tune your sound signal to the
desired response

Yes. Once your  eers™ are complete you can begin to use them
right away.
Note: Your ears most likely have never worn custom-molded earphones
before. Custom buds will be the most comfortable earbuds you have ever
owned, but you will need to break them in, just like a new pair of shoes.
For the first week, wear your custom earphones for only a short period and
gradually extend the time. By the end of the week, you should be able to
enjoy your earphones for extended periods without any discomfort.

Simply put your faceplates back to back and then gently wrap the cord
around your fingers. When the cord is wrapped, place in the pouch
provided to store neatly or travel with.

Yes, this is normal. The effect is called Occlusion Effect. This effect occurs
when the ear canal is acoustically sealed, vibrations like talking and
chewing no longer escape through an open ear canal—simply put, you
hear them more. Your eers™ are designed to seal your ear canal
from outside noise, thus filtering out louder external sounds and enabling
you to hear your music better and more clearly.

Yes, eers™ are designed for active performance, at the gym or
outdoors, rain or sunshine. However, eers™ earbuds are NOT
waterproof so please do not wear while swimming or drop them in water.

You can use any water-based lubricant on your customized earphones.

Some people simply use just water droplets or even saliva.
