is powered on again. For more information check “Bluetooth Pairing”
section.
If you have stored pairing information for multiple devices and more than
one of those devices is Bluetooth enabled, the BE Sport4 will
automatically connect with the most recently paired device.
For more information read section “Multipoint Connections”.
To turn the BE Sport4 to OFF, push Power/Function button for about 4

9
seconds until the LED indicator turns red and you hear the “Power off”.

MISCELLANEOUS
Multipoint Connections
If you have stored pairing information for multiple devices and more
than one of those devices have Bluetooth enabled at the same time,
your BE Sport4 will enable multipoint connection.

13
Multipoint connection allows your BE Sport4 to hold connections with
two devices at the same time while playing audio signal from only one of
the two devices.
Multipoint connection works in the following ways:
•Your BE Sport4 automatically connects with the most recently paired
device (“Primary device”).
•You must manually connect the second device (“Secondary device”)
to your BE Sport4 via its operating system.
•The BE Sport4 will prioritize the audio from Primary device.
•You can control Primary device using the BE Sport4 in line controller.
•When Primary device is idle, your BE Sport4 can receive audio from
Secondary device.
•Secondary device must be controlled directly from its operating
system.
•Simultaneous audio from both devices is disabled.
Water Resistant
NuForce headsets with the IPX5 water ingress rating are splash-resistant
and water-resistant, preventing malfunctions due to moisture entering
the body of the headset. However, the splash-resistant and
water-resistant qualities are non-permanent and may degrade with wear
and tear from daily use. Liquid damage is not covered by the warranty.
•To prevent liquid damage, please avoid the following situations:
Wearing the headset while swimming or showering
Exposing the headset to pressurized or high-speed water, such
as showering, water skiing, wakeboarding, surfing or riding a
water scooter, etc.
Using the headset in a sauna or steam room
Immersing the headset in water
Operating the headset outside the recommended temperature
range, or in extremely humid conditions
Dropping the headset or any other actions that cause the
headset to take impact
Disassembling the headset, including the disassembling of
screws
Not properly covering the USB charging port, causing water or
other foreign particles to enter the headset

14
•Types of liquids covered by the water resistance rating
The water resistance rating only applies to fresh water and tap water.
Other liquids such as the following are not within the scope of the
water resistance rating: soap water, solutions mixed with detergents,
solutions mixed with bath products, shampoos, hot spring water,
swimming pool water, seawater, soap water, detergents, salt water,
perfumes, insect repellents, lotions, sunscreens, oils, gel removers,
hair dyes, and solvents.
•Micro-USB port cover is crucial to maintaining the water-resistant
quality of the headset. When using the headset, make sure that the
Micro-USB port cover is tightly closed. If there are foreign particles
on the cover, or if the cover is not fully closed, the headset will lose
its water resistance capability.
•If the headset has already come into contact with liquids, remove all
connected cables and do not charge the headset until it is fully dry.
Using or charging the headset or accessories while they are wet may
damage your headset.
•The charging box (if any) containing the genuine wireless Bluetooth
headset does not have a waterproof design. Any water-resistant
qualities described in the product specifications are limited to the
body of the headset.
•If the headset is not wiped after being worn during a workout, the
salt from the sweat may negatively impact the lifespan of the
headset. Therefore, we recommend that you use a clean cotton
cloth to wipe the headset after your workout, in order to keep the
headset clean.

15
Bluetooth Connectivity
Bluetooth is a short-range wireless technology. Its connection quality
may be interfered with metals, walls, and devices including but not
limited to microwave ovens. At the same time, Bluetooth’s 2.4 GHz
frequency is also shared by some Wi-Fi connections, which may result in
a slower connection. This technical problem cannot be completely
eliminated despite Bluetooth’s status as an international standard.
A Bluetooth headset’s wireless transmission is not limited to the
connection between the headset and the signal transmission device, but
also between the main and auxiliary earbud. Therefore, when using a
genuine wireless Bluetooth headset, we advise placing the signal
transmitting device (such as your cellphone) on the same side as the
main earbud in order to reduce the potential technical limitations of
Bluetooth signal shielding to some extent.
The connection quality of the Bluetooth headset is influenced by factors
such as the Bluetooth device connected to the headset, the
communication environment, or the environment in which it is used. If
the headset audio is intermittent, please run through the following
scenarios to identify and avoid the following caused by environmental
interference:
There are obstacles such as people, metal objects, or walls between
the headset and the Bluetooth device.
There is a Wi-Fi device in use near the headset.
There is a microwave oven in use near the headset.
There is an electromagnetic radiation generating device in use near
the headset.
The distance between the headset and Bluetooth device exceeds 10
meters
Restore Factory Settings
When you restore the BE Sport4 to its factory settings, the paired devices
stored will be deleted.
To restore factory settings:

16
1 Ensure that your BE Sport4 are not connected to any device.
2 Put the BE Sport4 in pairing mode.
3 Press simultaneously the Power/Function, Volume Up, and Volume
Down buttons for 2 seconds until the LED indicator flashes red five times
and you hear five short tones from the BE Sport4.
Because all pairing information is deleted after restoring factory settings,
the BE Sport4 will directly enter pairing mode once powered on.
