They are large, but not quite as huge as they seem via the photos.
When you said headphones, I thought you meant full sized. The Senns despite their size, are both extremely comfortable surprisingly light. They will fit completely over the ears and thus cause very little fatigue over hours and hours of use at a single sitting. They also stay relatively cool on the ears and the sound is excellent with tight base all the way up through clear concise highs. The pads are soft and comfy.
If you need a smaller/different solution, give me a general idea what you might consider an acceptable size and type and maybe I can offer a suggestion or two.
