yea bro, the sound quality will be amazing. Theres a review on headfi if youre looking for a professional's comments (http://www.head-fi.org/products/massdrop-x-hifiman-he350) but theres a lot of terminology you wont understand unless you're really deep in the audiophile community.
anyway
the main things about those headphones are:
1. its open back, so you can hear everything around you + the music, which some dont like ; but the first time i listened to a pair of open back cans, i loved them. Its like having a soundtrack on top of your life. You can have a normal conversation without having to remove em, its really enjoyable.
The fact its open backed allows for something that audiophiles really enjoy having in their headphones: a large soundstage. why do you want that anyway right? because its like being at a live event. a dude on headfi once said "i could hear the musicians coughing and the crowd at the back of my head" and that's when I truly became interested in audio.
