I got a chance to listen to these through 3 days home audition program.
Sound quality: First impression the sound was airy.
I do own a few popular headphones like Sennheiser Momentum 2.0 and V Moda M100, But I was not satisfied with their sound. They sounded harsh to my ear and congested. So I was looking to go a step up on the ladder and tried Cascade. The first thing that hit me was refined sound, smooth, no harshness.
Comparison with Beyerdynamic DT 1770 Pro another close back in similar price range Cascade was having a comfy pad and Bass was extenuated but that soft sub bass that you can feel in your gut was not there in either. DT 1770 Pro sound was smoother and easy to listen to.
Ergonomics: Headphone is a bit heavy. The overall construction doesn’t give that snug fit. If you rotate your head too much the headphone will fall away. Though the ear pad was very comfy but missed soft feel of memory foam.
