Notes on water resistant feature

Water resistant performance of the neckband speaker

The neckband speaker, with the cap closed securely, has a water resistant specification of IPX4*1 as specified in “Degree of protection against splashing water” of the IEC60529 “Ingress Protection Rating (IP Code)*2.”

However, the neckband speaker is not completely waterproof. Do not drop the neckband speaker into hot water in a bathtub or purposely use it in water.

Liquids that the water resistant performance specifications apply to

Applicable fresh water, tap water
Not applicable liquids other than the above (soapy water, water with detergent or bath agents, shampoo, pool water, hot spring water, salt water, etc.)

*1 IPX4 equivalency: The neckband speaker maintains its performance while subjected to water sprinkled from every direction. This means that no trace of water is found inside the neckband speaker after a 10-minute test with water of 10 L/min sprinkled from a distance of 300 mm to 500 mm (11 7/8 in to 19 3/4 in) in every direction.

*2 The supplied accessories and the connectors of this neckband speaker (USB) are not water resistant. To reduce the risk of fire or electric shocks, do not expose the neckband speaker to water or droplets while using either or both of the connectors (USB). Do not place a vase or any other liquid-filled container on the neckband speaker.


The water resistant performance of the neckband speaker is based on our measurements under the conditions herein described. Note that malfunctions as a result of water immersion caused by misuse by the customer are not covered by the warranty.

To avoid the deterioration of the water resistant performance

Check the following and use the neckband speaker correctly.

  • This neckband speaker does not have a design that is resistant to water pressure. Do not put the neckband speaker in the water or directly under the water gushing out of the faucet to avoid a malfunction.

  • Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the neckband speaker directly. Also never use the neckband speaker in a place subject to high temperatures, such as in a sauna or near a heat source.

  • Handle the capwith care. The cap plays a very important role in maintenance of the water resistant performance. When using the neckband speaker, make sure that the cap is closed completely. When closing the cap, be careful not to allow foreign objects inside. If the cap is not closed completely, the water resistant performance may deteriorate and may cause a malfunction of the neckband speaker as a result of water or dust entering the neckband speaker.
