Which should you buy?

• ▸Both are open-back — imaging comes down to tuning. Sennheiser HD 560S: neutral, wide stage with precise left-right placement — a community favourite for competitive footstep cues.
• ▸Sennheiser HD 560S needs only ~8.3 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.
• ▸Sennheiser HD 560S 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.
