After my old headphones (MDR-EX 500LP) had fallen victim to a cable break, Sony exchanged to them directly and sent the 510LP to me. The 510LP have a great sound even when slightly larger than the 500LP. The hybrids in-ear cushions do exactly what they want, namely noise outside can be in front, very convenient in a noisy environment (eg in the UNI). Normal pads are also included.
A positive surprise was that the cause of the broken cable (which has occurred directly at the point at which the cable splits) has been fixed.
