Despite the product description, the sound quality and comfort are comparable to the free headphones you used on the plane. Very poor noise cancellation, poor sound quality and I don't know why they ask you to rate the volume control - you do that with your device, not your headphones. However, one cannot expect very high quality for 13 euros. They will work in a pinch, but I wouldn't recommend them for long-term use. You get what you pay for.
