After days of usage and comparing with M50s, sound is pretty good but still finding it rather bass heavy. Used it with my macbook and bass is emphasised more on the low end side while mid and highs are a little recessed. However, sound is greatly improved connecting with my Udac 2 with the extra ooommpph.
Overall, I will give it a 3.5/5. It's a very good first attempt by Nuforce. I would appreciate if the bass doesn't overwhelms the details and staging. And design is rather generic looking with a more flimsy feel as compared to the competition. These are ideal for those who loves Techno, Trance, Electronic, R&B, Hip Hop, Lounge, House Music. And they perform very well with movies and gaming as well.
