AKG K702 vs HiFiMan HE400se

Both scored on the same six factors, priced on what you actually pay including delivery, and each claim linked to the source it came from. Prototype data — prices and retailer stock are a fixed demo snapshot from 28 July 2026, not a live feed.

Verdict

The AKG K702 wins on both score and price.

Across these 2 headphones, the AKG K702 has both the highest Worth Score (8.1) and the best score per euro at 139,00 €. That is unusual — normally you trade one for the other. Its weak point is bass rolls off noticeably.
