That violet color is a higher-priced limited edition, too. Easier with the EX1000 because they're so similar. The 7550 is basically the EX-1000 minus some upper mid/treble presence. It's warmer and smoother while the EX1000 is brighter and carries more treble energy. The EX1000 has a bit more intelligibility and the presentation is more airy, but of course it's more prone to harshness as well.
