Short answer: the Sennheiser HDB 630. Both are rated 3.3/5 for sound quality (#285 and #283 of 481 over-ear headphones), and the Sennheiser HDB 630 costs $489.95 against $549 for the Shure SRH1540, and with sound quality even, the cheaper one is the better buy.
The case for the Sennheiser HDB 630: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. The catch: Treble sits about 4.5 dB low, so it sounds a little dark.
What the Shure SRH1540 does well: The smoothest of this group, with just 2.33 dB of deviation and a biggest dip of only 3.3 dB near 8.6 kHz, so treble is more even and cymbals keep their detail. Watch for: Upper bass sits about 5.1 dB above target, which adds warmth and some boom that can cloud kick drums and male vocals.
Buy the Sennheiser HDB 630. Both are rated the same for sound quality, and it costs $59.05 less than the Shure SRH1540.
