I brought this as it was advertised as 180s, but it was not when it came. The ear warmer is large, so it's nice to be able to cover much of the ears and not have it feel tight like my current 180s. The rating is not as high since I am comparing it to 180s, which is better quality, and I can twist it back and forth. It does the job if you just want to keep your ears warm.
