Comfortable closed headphones $150

I am about to receive my Audio Technica ATH-A700s in the mail today, and from what I hear they aren't too bad. I will post more once I try them out.

Idk if the Sennheiser 25-I-II or M50 supports glasses, but many recommend them. I also recommend the RP-21s, they have an angled slot specifically for glasses when you wear them. They also have a hard clamping force at first, which requires some overnight stretching and Beyerdynamic pleather pads for better long-term comfort.

My Audio Technica ATH-M50s did something similar, so I simply bent the metal head band a little...  Not sure why that won't work for you.

If you are happy with your Q40's, keep them. No need to get an entire new headphone due to some clamping force. Most closed headphones are going to have a pretty tight clamp, so the best way to get rid of that is to stretch them. No, not on your head, but around something. Many suggest putting them around a bunch of lined up books. Me on the other hand, use my glass mannequin to relieve clamping force.
 

My M50s are very comfortable with my glasses, but you might want to stretch them out a little bit first

If not, IEMs are always a good alternative for those who wear glasses

If you don't mind getting open back headphones, go for the HD595's. 

I have glass wearer friends, and they find the Sennhs comfy. 

I vote m50 audio teachnica also....

very comfortable..... and sounds great!
