Very well made, quality materials used. Good adjustability although they do clamp tightly to your head so can feel constricted over a long listening period. But this does help to keep noise out. I believe these were originally £270, which is not cheap. I bought my set after they were discontinued and paid 90 for a new set. I would say I have gift bargain of my hi fit buying life! The sound is superb. Even when using Spotify to stream I can hear a difference over my old AKGs. Would I recommend them at the full price? That’s a difficult call as I wouldn’t spend that much. But I feel very lucky to be able to use these headphones. Would be worth seeking out a used pair as you can change the ear piece unit - check out the sennheiser web site.
