"Sennheiser NoiseGard™ 2.0 technology provides up to 90% active noise
cancellation"

90% reduction may sound good but it's only ~10 dB, which is typical for most
active noise cancelling headphones.  If you're serious about noise
reduction, you should be looking for 30 dB, which is available in both
"in-ear" and "over-the-ear" style passive headphones:
