If the top darling were a bit more helpful or if the ears could still be pushed out, then they would be perfect. If the head is large or not standard, then it is advisable to wear them for three hours. If there was an opportunity to return, I would change it to others, since the discomfort is very strong Has pros: Good sound for bluetooth. Optimal noise. Ideal for airplanes. Holds battery well With its cons. The upper darling presses, now I'm thinking how to cut it off. In the store, the measurements were normal, the defect only manifests itself after three hours.
