4XX is a great value. Resolving and clear. Nice quality feel for a budget headphone. Cable is nice and flexible. A little heavy and hot on the head after extended wear. Fairly fatiguing and sibilant after extended listening. Not very good imaging. Highly recommended as an entry level unit.
Verum 1 is a great headphone. Slightly heavy but noticeable as top headband is super comfy. Stock pads are meh but better than 4XX. Still, recommend perforated ZMF (ori & universe both work great) helps with larger ear cavity, breaths better and you don't loose much bass extension. I imagine his perforated pads are also fine, just not as big ear cavity as I prefer. Great clarity, pretty darn good imaging, small soundstage. Stage seems narrow and tall, gives a large speaker presentation. Just big speaker presentation. Very natural timbre. Lots of contrast. Headband ergonomics and look are blah. Stock cable is blah. Astonishing price.
