Bildquality and Materials: 10/10
For the Massdrop price (100 Dollars) this is a great deal. However these are far from perfect. As mentioned the Bildquality is outstanding but they are very uncomfortable. The cups are too small to be over ear and too big to be on ear. Also the cups arent deep enough and my ears always touch the interior which is relatively hard. I cant wear them for more than an hour.
Sound is detailed but not all too clean it feels a bit muddy. Also there is practically no bass at all. If you compare the sound of the MJ2 against other 100 Dollar Headphones they do sound quite good but at the original price of around 500 Dollars this is a scam. I have dt880s (180 Dollars) and 1More quad IEMs (230 Dollars) which both sound much better than the MJ2s and cost less than half.
