My 2 cents...
I own the both headphones. Both are wonderful, each with its own characteristics.
Both headphones have the Shure sonic signature, delivering a detailed and airy sound, good soundstage and good instruments separation. The treble of both devices are not very extended.
Connected directly into the headphone-out of my Cowon iAudio X5, the main difference is an incredible dynamic and lively sound of the SE530, including therein a greater extent and detail of all frequencies. The highs are extended and detailed without being harsh, the mids have the characteristic of being very life-like and the bass is quite powerful, extended and detailed. This is the "wow!" headphones.
Moreover, the SE420, if at first may sound off and dull when compared directly with the SE530, has a great quality to be very neutral and balanced. Each frequency is exactly in its place, producing the impression of cohesion and organization, benefiting greatly the instruments separation, soundstage and aeration, characteristics that I appreciate a lot. It is a delight to hear him and allows many hours of fun without any fatigue. This is the "what the next song?" headphone.
If the SE530 definitely do not need an headphone amplifier, the SE420 is greatly beneficiated, increasing the sense of soundstage, instruments separation, aeration and depth. The highs and lows are more extended and detailed. Everything improves with the use of an amplifier, while still maintaining the characteristic of neutrality, cohesion and organization of the sound. With this setup, the Shure SE420 is something from another world, as if angels were singing in his ears ...
In short, put follows the main differences:
SE530
- It is more dynamic and lively, directly in the headphone-out of my player. It is as if it had a built-in amplifier;
- It's a phone for fun and some listeners may feel tired;
- The bass is detailed and extended, however, may overlap with other frequencies;
- The mids are wonderful and very real;
- Need a little equalization to play well;
- It's not as comfortable as the SE420 and the act of removing and placing it in the ears is a little more complicated;
- An headphone amplifier can bring more disadvantages than advantages.
SE420
- Loses in dynamics and liveliness directly in the output of headphones player;
- Has a more "professional" sound. Less tired for long periods of hearing;
- The bass is quite powerful. They are not as extended and detailed, however, are faster. The bass complement the music, never rising above the other frequencies;
- The mids are more recessed;
- Need a good equalization to play well;
- Very comfortable and easy to take and put in the ears;
- An headphone amplifier bring this phone to another level of sound.
Sorry about my poor english... :O)
