#151 Fostex TH900: $1,999.99 Amazon eBay
Pros: The closed back isolates well, and at 25 ohms and 100 dB/mW it plays loud from modest sources without a dedicated amp. Its large 50 mm dynamic driver and warm leaning tuning suit listeners who prefer a rich, colored sound, and it matches the rating of the AKG K872 Pro.
Cons: A preference score of 48 in crinacle’s measurement places it well away from the Harman target, so most listeners will hear a strongly colored balance unless they apply EQ. The Sennheiser HD 820 rates higher at about the same price, and the 400 g weight is heavy for an over-ear.
