Dual noise cancellation

To get the best noise cancelling experience we have combined both active and passive filtering in NERO-TX PRO.

The active cancellation is handled by the processor that works together with the microphones to cancel out the incoming disturbing noise from your surroundings. The quality of components in combination with the speed of the processor are of essence for the efficiency to erase interfering frequencies.

The passive cancellation is handled by the Comfort Foam Tips©. A proprietary earphone tip in adaptive foam material (viscoelastic polymer) that adapts to the shape of the ear canal giving a comfortable and tight fit, significantly enhancing your sound experience.

NERO-TX PRO also have a feature called Transparency Mode. In this mode you filter out disturbing noise and at the same time let through and amplify conversational sound so you can easily communicate with the people around you.

SUPRA Quad Response©

Our proprietary 4-way microphone technology filters out all unwanted frequencies from your surroundings. This results in clear calls even if you are in the middle of a noisy environment.

The Nero-TX PRO 2nd Generation supports the latest generation of HD calls. It can handle data during calls with a sampling frequency of 48 kHz in the frequency range 20 to 20,000 Hz (20 kHz), whereas standard calls support a sampling frequency of 8 kHz in the frequency range 300 to 3,400 Hz (3.4 kHz).

Powermag©

The charging case, Powermag II©, is extremely powerful despite its very compact size. Thanks to the integrated high-performance battery, you can charge the earphones up to 16 times, providing a total playtime of over 120 hours. The playtime on a single charge is over 7 hours.

Powermag II© can also be used as a power bank via its USB-A output (output 1A). This can be very convenient if you need to charge your phone while on the go.

The smallest on the market

NERO-TX PRO 2nd Generation is the market’s smallest true wireless earbuds with noise cancellation. Despite its extremely compact size, the earbuds deliver powerful and dynamic sound, and thanks to advanced digital technology and high-efficiency batteries, you get over 7 hours of playback time.

The compact nano format almost makes you forget you’re wearing earbuds, and because they are so small, they fit most ears regardless of size.

IPX6 Certified

NERO-TX PRO 2nd Generation has undergone several improvements compared to its predecessor, enabling it to withstand the toughest conditions. The earbuds are certified to IPX6, meaning they are splash-proof, sweat-resistant, and dust-resistant. Thanks to this, you can enjoy your favorite music regardless of weather or workout type.

Aircraft composite

NERO-TX PRO 2nd Generation is an all-round earbud designed and built to withstand the heavy demands of daily use. The earbud housing is made from a composite material often used in the military aviation industry due to its superior durability and strength relative to its weight.

Multifunctional buttons

NERO-TX PRO gives you full control over your smartphone’s functions. By clicking once, twice or three times on the button, you can easily adjust the volume, change track, answer/end voice calls, play/pause music. You can easily answer or end a voice call with the simple press of a button. With NERO-TX PRO, you can also activate and communicate with your voice assistant, for e.g. Google Assistant™, Siri™.

One piece headset

NERO-TX PRO also has a so-called “one piece function” (TWS+) that allows you to use only one earphone at a time during listening or voice calls.

The SUPRA Audio© app gives you the ability to customize NERO-TX PRO 2nd Generation to your own preferences.

  • Choose between preset sound characters
  • Switch between ANC modes
