Best sounding closed back headphones under 100$

The headphones need be closed back type in order not to upset my wife at night.

My sound taste is as follows:

1. I want no harshness and edgy mid (I am a class A amp guy).

2. I believe that most of the music lies in the mid range.

3. I like clarity and sweetness.

4. Impressive bass is nice but not first priority.
