Quick start
- Charge your NERO-TX in the charging box (Powermag©) until the LED light on the earphone turns off. The LED will light up white during the charging process.
- Activate Bluetooth® on the transmitting device (e.g. smartphone).
- Take out both earphones from the charging box. It will then begin automatically searching for a device to pair with. When the earphones are searching for a device, the LED will light up white and you will hear a voice that says: “pairing”.
- Connect the earphone by selecting NERO-TX from the list of available Bluetooth devices on the transmitting device.
NOTE! Charge the charging box by connecting the supplied charging cable to the USB-C port. The larger USB-A port is for outgoing current only. Read more in the section entitled Powermag©.
Comfort and fit
In order to ensure optimal comfort and fit it is important that you choose the right size of earphone tips. The tips that are too small for your ear canal will result in weak bass and may allow disturbing ambient noise to reach your ears. Tips that are too big may prove uncomfortable to wear over time.
It is also important to position the earphones correctly in your ears. Earphone positioning affects both your audio experience and also wearing comfort. Begin by placing the earphone with the cushion placed downwards and then twist it 90 degrees into the right position as shown below.

Powermag©
The accompanying storage and charging case, called Powermag©, contains a powerful battery that can recharge the earphones up to 16 times, giving a total playtime of up to 80 hours.
The charging case also has a power output function via the USB-A connection, which means that it can also double as a reserve power bank for other devices such as your smartphone. You can make use of this function by connecting a USB cable to the USB-A port on the charging box and to your smartphone (charging will start automatically). When this function is active a white LED will blink (above the USB-A port). NB: Never charge products that do not have a 5 Volt input as this can cause damage to the device being charged.
When the battery level of the charging box becomes low, the LED light will start flashing white. Charge the box by connecting the charging cable supplied. The LED will flash white during the charging process. When the light shines this means that the charging box is now fully recharged. NB! It is important that you connect the supplied charging cable to the smaller USB input and not to the larger USB-A connection. This connection is only for outgoing current.
In order to protect the USB ports on the charging box, we recommend that you close over the silicon cover whenever the ports are not being used.
