They are very flexible and bend to become very small to fit in your bag or pocket. There is also a strap to adjust the setting to the top of the head by increasing or decreasing the size depending on the size of your head which is very convenient because no one has the same head size that it has to other businesses that consider these criteria.
With all these features, the sound is not compromised. Clearly and certainly not stifled by the soft and thick material that covers them. They are great and hard to catch them out. I would recommend that nimporte découteurs in need this winter or audio headphones (could also be a good gift for Christmas).
