Terrific sound for the price. Throw away the stock tips! Get comply foam tips, burn in for 60ish hours - and you have a great daily driver. Detailed, crisp, balanced, and controlled across the range, great isolation.
GramblorDepending on the glasses and the pads in question, they could theoretically tamper with the seal, thus affecting (predominantly) bass response.
Not the most likely situation in the world, but more real than burn-in.
