Short answer: the Stax SR-L300. It ranks #20 of 216 over-ear headphones by sound quality, rated 4.3/5, at $455; the Grado Hemp ranks #53, rated 4.1/5, and costs $495, so there is not much of a tradeoff to weigh.
What the Stax SR-L300 does well: An excellent preference score of 89 in crinacle’s measurement, among the closest tunings to the Harman target in its class. The catch: As an electrostatic headphone it needs a dedicated Stax-compatible energizer to run at all, which adds real cost and a box on the desk.
What the Grado Hemp does well: A preference score of 83 with mids within about 1 dB of target (upper mids 1.1 dB above, low mids 0.2 dB above) gives vocals and instruments a natural presence. The catch: Sub-bass is about 10 dB below target under 60 Hz, a large loss that removes most deep rumble.
Buy the Stax SR-L300. It is rated higher for sound quality than the Grado Hemp and costs less, which makes it the one to get unless you need something the other one does better.

Stax SR-L300: $455.00 Audio46 eBay
Pros: An excellent preference score of 89 in crinacle’s measurement, among the closest tunings to the Harman target in its class. The open back push-pull electrostatic driver gives a wide, airy presentation, and at 323 g it is light for a full size headphone.
Cons: As an electrostatic headphone it needs a dedicated Stax-compatible energizer to run at all, which adds real cost and a box on the desk. The open back leaks sound and blocks no outside noise. The Beyerdynamic DT 900 Pro X shares the same rating for less money and plugs into ordinary gear.

Grado Hemp: $495.00 Amazon eBay
Pros: A preference score of 83 with mids within about 1 dB of target (upper mids 1.1 dB above, low mids 0.2 dB above) gives vocals and instruments a natural presence. Bass from 60 to 200 Hz is within 1 dB of target, and the neutral tilt of 0.09 fits listeners who want a balanced tonality. At 38 ohms and 99.8 dB sensitivity it is easy to drive from a phone or laptop.
Cons: Sub-bass is about 10 dB below target under 60 Hz, a large loss that removes most deep rumble. A 5 dB peak near 2.2 kHz can add forwardness to voices, and a 6 dB dip near 5.3 kHz takes some bite from cymbals and consonants. The open back leaks sound and gives no isolation.
