Pros: Soundstage, Mids, Well textured bass, clear treble, comfort
Cons: Only the 3m. cable, just innecesary for me
Compared to my Apple EarPods, it has so much better clarity on the treble and bass, also in the mid.
Really good buy, LOVE those things!
Used it with: iPod touch 5G 64G (without amp) and sounded fantastic, really clear vocals, and FOR ME it works for Metal music, but, depends of what you are hearing...
EDIT: After 2 days of burn-in, it sounded 2x better, surprised.
