Pros: Great sound, good isolation, comfortable, DURABLE, cable quality
Cons: For the price? None.
Straight out of SANSA Clip+
Bass is accurate, punchy and deep, the mids are slightly recessed and the treble is very crisp. Clarity is up to Fischer standards, no veiled sound here.
Overall they sound very similar to the ATH M50, but with less recession and greater clarity (though less inviting imaging)
These are one of the best IEM's I'ver ever heard, and for the price they are practically unbeatable.
