• If both (R) and (L) headphones are turned on, the main headphone is the right (R) headphone (feature of True Wireless Stereo technology). The location of the signal source on the right side reduces the likelihood of its interruption due to interference from obstructions and signal dispersion (for example, the location of the smartphone in the right front pocket of the clothes can reduce signal interruptions compared with the location in the left).

• The right headphone is the main one, receives bluetooth signal from the source and relays it to the left headphone (in case of stereo operation). In this regard, the discharge rate of the battery of the right headphone is higher than that of the left one (the exact indicators depend on the volume of audio playback, as well as the presence of noise during signal transmission).

• The headphones and charging case have a protective nano-coating that allows them to remain operational even after immersion to a depth of 1 meter and lasting up to 30 minutes, which corresponds to protection class IP 67.

• After immersing the headphones and/or case in water, for normal operation of the device, we recommend drying it before use. To do this: shake the opened case slightly, water will flow out of it through the micro-USB port and ear cushion grooves; remove the ear cushions and make sure that there is no moisture in order to prevent water from entering the ear canal; if possible, dry the product with a household hairdryer for several minutes without using air heating or wait for drying naturally.

• Don't immerse the included charging case with headphones in the water.

• Do not immerse the charging case with the micro-USB power cable in water.

• Bluetooth radio signal (2.4 GHz) is greatly attenuated when passing through a conductive medium (in water, for example). In this regard, despite the presence of moisture protection, using headphones under water to listen to audio is not possible.

• After using the headphones in training, as well as getting soap or sea (salt) water on them, it is recommended to rinse them with running water and dry them.

• Use only the supplied ELARI charging cable. Using non-original cables may damage the headphones or, in the event of adverse circumstances, cause the battery to explode and void the product warranty. 

• Gradually, charge and discharge cycles of the headphones will reduce battery life. This is normal for any battery.

• Don't make incomming or receive calls while charging the headphones.

• When the battery level is low, the headphones will repeat the voice message “Battery low” and the indicator will flash red. If the headphones are discharged during the call, it will be automatically redirected to the smartphone.
