The newspaper Sound & Image have tested our upgraded version of the NiTRO-X Hybrid . In the previous test NiTRO-X was in they received the award "Highly recommended" and in this test with the upgraded version they are described as even better!
“I've worn the Nitro-X Hybrid ANC on airplanes on a couple of occasions and the noise cancellation does a good job of removing the noise. Actually better than I expected. I never missed either the Sony WH-1000XM5 or the Sennheiser Momentum 4 Wireless, both of which remained in the drawer at home.”
