One may of the active suppression but do not expect too much, there are only low frequencies (aircraft turbine noise, motor hum etc.) suppressed. Screaming children quatschige neighbor and high sounds are so attenuated only by the "passive" insulation the fluffy ears.
I've tested a lot of Noise Cancelling Headphones. From the processing and noise reduction, these are very satisfactory, the price-performance ratio is super. While the headphones playing acoustically in the 300-EUR-league, but offer in the under 100-EUR-Class an exceptionally good performance in terms of comfort and acoustics. I would even go so far as to compare it with the Bose QC3 - the design is the same, the power of repression is at a similar level.
Phenomenal is the battery life. Did with the first battery (only one is needed) already completed 10h short Testreisen-, flights and 2 long-haul flights รก respectively 12h and the battery is still alive. With a AAA so you get good + 35h.
Class is also the supplied accessories:
2x AAA battery, stable and compact plastic box for transport, dual jack airplane adapter.
Summary:
Acoustics / Sound: 4/5

Noise Cancellation: 5/5
Stability: 4/5
Comfort: 5/5
Delivery: 5/5
