I've read reviews of Music Hall components for years in Stereophile, and the manufacturer's comments in the back of the magazine, containing entertaining banter between the reviewer and manufacturer. I was hoping for a hi-fi or mid-fi headphone from these guys, and my expectations came up short. A light bass impact, some very slight treble peaks, or a modest treble rolloff - any or all of these can be had in many headphones that sell for $200 USD or less. In the case of the DE-BE however, the sound required significant EQ to be usable for hi-fi listening indoors or out, and so this is an "EQ review" that's intended only for people who are OK with using equalizers.
