Short answer: the HEDD Audio D1. It ranks #22 of 216 over-ear headphones by sound quality, rated 4.3/5, at $799; the HIFIMAN HE1000 Stealth ranks #30, rated 4.2/5, and costs $949, so there is little reason to consider the other one.
What the HIFIMAN HE1000 Stealth does well: Planar magnetic drivers deliver a preference score of 87 with bass from 60 to 200 Hz about 1 dB above target and sub-bass only about 2 dB light, so low end has solid weight and extension. The catch: The treble is uneven, with an 8 dB dip near 9.4 kHz followed by a 7 dB peak near 11.9 kHz and air above 10 kHz about 5 dB over target.
Buy the HEDD Audio D1. It is rated higher for sound quality than the HIFIMAN HE1000 Stealth and costs less, so only choose the other one for a particular feature it does better.

HIFIMAN HE1000 Stealth: $949.00 Amazon eBay
Pros: Planar magnetic drivers deliver a preference score of 87 with bass from 60 to 200 Hz about 1 dB above target and sub-bass only about 2 dB light, so low end has solid weight and extension. A 32 ohm impedance is easy to drive, although the 93 dB sensitivity still rewards a capable amp. Its rating matches the Sennheiser HD 800 S at a lower price.
Cons: The treble is uneven, with an 8 dB dip near 9.4 kHz followed by a 7 dB peak near 11.9 kHz and air above 10 kHz about 5 dB over target. That gives a sparkly, somewhat bright top end that can sound splashy or sibilant on certain recordings. At 458 g it is heavy for long sessions, and the open back leaks sound.
