Mage Audio DT770 vs Stock DT770

Mage Audio DT770 vs Stock DT770

Just to get a clear picture of the differences made by the Mage Audio mod (Red) vs stock (Blue). Better seal on these measurements. Comparison to the Sennheiser HD600 coming shortly. Will be doing some more comparisons in the near future to help give a better idea of how these sound. Stay tuned!


3 Mage Audio DT770s Measured FR


Here are measurements from 3 separate units of Mage Audio modded DT770s taken using the minidsp EARS. The plush earpads of the DT770 make positioning moderately difficult, but these are pretty consistent measurements across multiple units. Having a wide variety of modding resources available to compensate for stock unit variations and channel imbalances helps a lot.

Black Mage Updated Measurements

Now that I’ve had the mini ears DSP awhile I thought it would be a good idea to post some measurements. Keep in mind these will look different from measurements made on HATS or GRAS, and also will look a bit different than rigs without a pinea. For comparison I’ve also posted the stock DT770, the Sennheiser HD650, and the MrSpeakers Aeon Closed. Minimal smoothing is applied to better show gross differences.

Black Mage $265 USD



UPDATE: All Mages are now shipping with stock silver pads at a new price of $265!

Thanks to a fortuitous confluence of factors, I’ve been able to get the price of this headphone down to under $300. This is in keeping with my aim for the Black Mage, which is to offer the best possible sound at the lowest possible price. No figured wood, no soft leather, no beryllium, and no premium price.


Black Mage Review


Stu Black at homestudiobasics.com knows headphones- he’s reviewed over 70 of them on his website. He and I were introduced through a mutual acquaintence at Audio Advice here in Raleigh, and when I had finished tweaking the last edition of the Black Mage, Stu agreed to give them a listen and possibly write a review if he liked them. After listening to them for a couple of days I got an email from him with his initial impressions:

“Wow…how did you get a closed back headphone to sound so open?”

Stu remarked on the phenomenal clarity and near-perfect treble, as well as the articulate bass that sat just right in the mix, and he told me a review was forthcoming. You can check out his comprehensive review here:


-“I don’t want to say these are as good as a Focal Utopia, but I’m almost inclined to compare the two.”

-“I was flabbergasted listening to tracks I’ve heard many times over…Decay, Instrument Timbre, Soundstage, Instrument separation, and clarity are all absolutely stunning to the point of it being almost too much for me to handle.”

A big thanks to Stu for putting the Mage through its paces!


Recent Measurements: Mage Audio DT770, HD650, Stock DT770

Just a periodic update showing some recent measurements with comparisons. Due to variation between units, and then variation between left and right channels, the DT770 takes longer than it should to mod. Sticking to a target response takes a lot of work.
