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
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.
If the headset has already come into contact with liquids, 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.

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.

Voice Prompts list
