I received a pair of these eco-friendly iems from my friend Mr.Fournier. They are gorgeous -looking with real wood finish and metal accents. After testing them on the streets of boston and Cambridge, and comparing the MS-01 to other worthy headsetts, this is my review.
For: Eco friendly, prestine design. Snappy, crisp highs. Good vocal performance. Carbon-fiber reinforced cord,
Against: $120.00 retail price tag. Upper bass dominance does not help with low bass definition. Highs are recessed (can't distinguish various cymbals, lack of airines in classical violin music).
Overall performance: great for those who like upper bass, high-powered heavy metal, reggae, hip-hop.
