ii VoiceBud VB25 Hearing Aid | Smart Device App and Battery Information
Information About Rechargeable Batteries used in the ZVOX VoiceBud VB25s
And VoiceBud Charging Case
Each ZVOX VoiceBud VB25 hearing aid has an internal
rechargeable battery. A VB25 is recharged using the ZVOX
VoiceBud Charging Case. The VoiceBud Charging Case
recharges two VoiceBud VB25 hearing aids at the same time.
When the charge in a VB25 battery nears exhaustion, you will hear
two rapid beeps. This is your signal to recharge both VB25s as
soon as possible.
In typical operation, the Charging Case is connected to a USB
jack with the included USB charging cable. Since this USB jack
supplies the charging current used by the Charging Case, the USB
jack should be supported by an AC power connection. The Charging
Case fully recharges two VoiceBud VB25 hearing aids in about six
hours. The indicator lights on the Charging Case next to each
VoiceBud turn blue when the recharge session is complete.
The Charging Case features its own internal battery. Once this
Charging Case battery is fully charged, the Charging Case can
recharge two VoiceBud VB25 hearing aids without a power
connection. The Charging Case can fully recharge two VoiceBud
VB25 hearing aids three times before its internal battery is depleted.
After a 2 hour charging session, the Charging Case’s back panel
indicator light should turn blue. This indicates the internal battery
is fully charged and it can be used in portable operation again.

Battery Charging Guide
(VoiceBud VB25s and the Charging Case)
A
A VoiceBud VB25 will begin to emit two rapid beeps
when its battery charge is low. Recharge the VoiceBuds
when this occurs.
Under normal operation, the Charging Case should be
connected to a USB jack using the supplied cable.
See illustration on previous page.
Conrm the Charging Case power light is on
(red or blue) after connecting the USB charging cable.
Open the lid of the Charging Case.
VB25 Charging: Open the lid of the Charging Case and

8 VoiceBud VB25 Hearing Aid | Charging Case Portable Operation
Notes:
• The battery inside a VoiceBud VB25 supports a minimum
of 500 charge cycles.
• The Charging Case battery also supports a minimum of
500 charge cycles.
• The Charging Case’s internal battery charge level is
only relevant when the Charging Case is used in portable
operation. If the Charging Case is receiving power through its
USB charging jack, it will always recharge a pair of VoiceBuds.
Charging Case Portable Operation
A fully-charged Charging Case can recharge two VoiceBud VB25
hearing aids three times before the Charging Case’s internal bat-
tery needs to be recharged. Once connected to an AC-powered
USB jack, the Charging Case needs only 2 hours to recharge its
internal battery.
Before portable use of the Charging Case, conrm the Charging
Case is itself fully charged. The power socket light on the back
of the Charging Case is red while the Charging Case’s battery is
charging. The power socket light turns blue when the Charging
Case’s internal battery has reached a full charge.

VoiceBud VB25 Hearing Aid | Choosing An Ear Dome 9
Choosing An Ear Dome
The VoiceBud hearing aid comes with the medium closed dome
installed on the sound tube. If this ear dome feels loose or tight in
your ear, use a larger or smaller ear dome.
To Detach an Ear Dome
Detach an ear dome by pulling it straight off the sound tube.

To Install an Ear Dome
Note the orientation of the ear dome in the diagram. Push the
opening in the back of the ear dome over the ribs at the end of
the sound tube, as shown. The end of the sound tube should be
ush with the front of the ear dome.

Closed versus Open Ear Domes
Instructions starting on page
20 describe how to use the
supplied tool to remove and
attach the sound tube.
Detaching and Installing a VoiceBud’s
Sound Tube
An open ear dome allows more outside sounds to reach
your ears, combining with the sound from the VoiceBud
hearing aid. This sounds more natural to many VoiceBud
users. However, an open ear dome choice may limit the
amount of amplication you can use. The increased sound
level from the VoiceBud may generate ‘feedback’ (see page
15) because the output of the VoiceBud’s speaker is picked
up by the VoiceBud’s microphones. A closed ear dome allows
a VoiceBud user to use more sound amplication because it
isolates the VoiceBud’s speaker from its microphones.

VoiceBud VB25 Hearing Aid | Wearing a VoiceBud 11
1. Position the VoiceBud so that the sound tube drapes over
the front of your ear. Hold the sound tube with one hand and
then use your other hand to gently push the eardome into
the ear canal. Do not use strong force to insert the eardome.
2. If the ear dome feels loose, replace the ear dome with the
larger ear dome. If the ear dome feels too tight, use a smaller
dome.
3. Position the Stabilizer Arm inside the earlobe as on the
next page. The tip of the stabilizer arm can be trimmed
for a better t (1/8 inch).
4. When the dome is placed correctly, you should not be
able to see the sound tube sticking out from your ear
when facing a mirror.

There are Left Ear and Right Ear sound tubes. Hold the

the correct sound tube.

VoiceBud VB25 Hearing Aid | Operation of Your VoiceBud 13
Operation of Your VoiceBud
There is a multi-function rocker switch located on the top of your
VoiceBud hearing aid.
Volume Control:
To increase volume, tap the top of the switch.
To decrease the volume, tap the bottom of the switch. You should
hear a brief “beep” with each tap of the switch. Volume Up
Volume Down
Using Your VoiceBud
We nd many people use Mode 2 (noisy room) most of the
time. We suggest you wear the VoiceBuds for sessions of at
least two hours at a time. This gives you ample chance to
notice the clarity improvement in everyday sounds.
The VoiceBud may sound unnatural at rst. But you should
quickly notice the improvement in your ability to engage in a
conversation.
Feedback (Squealing)
Each VoiceBud includes two sensitive microphones and a speak-
er. The VoiceBud picks up quiet or distant sounds and amplies
these sounds so you can hear them better.
As you increase the volume setting of the VoiceBud, the chance
increases that the microphones will pick up the sound from
its own speaker. This ‘feedback’ is heard as a squealing note.
Decreasing the volume setting eliminates feedback.
A closed ear dome provides more feedback resistance than an
open ear dome, allowing a VoiceBud user to benet from more
amplication.

14 VoiceBud VB25 Hearing Aid | Sound Mode Selection
Sound Mode Selection
A VoiceBud has four Sound Modes. Press and hold down the top button
for 3 seconds to select a mode. Listen for the number of beeps.
Mode 1: Speech (one beep is heard) The default mode. Use it
for conversation, in any place without much distracting sound.
Mode 2: Noisy Room (two beeps) Use when inside a space
with distracting noises and other people talking.

VoiceBud VB25 Hearing Aid | Sound Mode Selection 15
Mode 3: Automobile/Road Noise (three beeps) Use when
inside moving vehi cles.
Mode 4: Telecoil (four beeps) Use in venues or with devices
that display the Telecoil sound support logo.
The VoiceBud will advance to Mode 1 after Mode 4. When the VoiceBud is turned on, the VoiceBud will select the mode in use when it
was turned off.

16 VoiceBud VB25 Hearing Aid | Care of Your VoiceBud
Care of Your VoiceBud Hearing Aid.
Foreign matter and condensation can eventually collect in the
sound tube. If this happens, the VoiceBud’s sound level will
drop. If you notice a drop in sound level, use the cleaning tool
to clear the sound tube.
ZVOX Audio also recommends using the cleaning tool at six
week intervals to ensure the sound tube is clear.

4. After using the cleaning tool, use your mouth to gently
blow a stream of air through the sound tube. This will help
remove any remaining condensation.
5. Use the cleaning tool’s brush to clear any foreign matter
around the VoiceBud’s sound tube socket.
