Koss PRO DJ100 - ranked #146 of 382 Over-Ear Headphones · Editor's rating 3.8/5

#146 Koss PRO DJ100 Discontinued eBay

Pros: Crinacle’s measurement gives it a very good Harman preference score of 78 with a 2.78 dB spread. Its tonal tilt of +0.08 sits close to the target, so the overall balance is neither dark nor bright. It uses 1 x 40mm dynamic.

Cons: Discontinued, so it is mainly found used. Its 2.78 dB spread is less even than the best measured sets.
