Which should you buy?

• ▸Both are open-back — imaging comes down to tuning. Beyerdynamic DT 990 PRO (250Ω): very wide, airy stage — a classic footstep favourite; 250Ω + low sensitivity needs a real amp.
• ▸Beyerdynamic DT 990 PRO (250Ω) needs only ~25.1 mW for clean 110 dB peaks vs ~39.8 mW for the HiFiMan Sundara — easier to run loud and clean off a modest amp or even a dongle. The HiFiMan Sundara rewards (or needs) a real amp.
• ▸Beyerdynamic DT 990 PRO (250Ω) grades higher for footstep imaging (5/5 vs 4/5) — the one axis that's a real competitive edge. But it saturates: any clean open-back clears the bar, so a higher score above baseline buys little. General-use and music grades are comfort/preference, not advantage.
• ▸Beyerdynamic DT 990 PRO (250Ω) is the more affordable class — Value vs Premium. Put the saving toward an amp that drives it properly before jumping a price tier.
