Atticus:  [AT.i.kuhs]

Atticus,a name that encompasses wisdom through experience, is tuned as such. Often audiophile’s are told to search for a neutral sound, when in practice, warmth is what is most pleasurable, desirable and most lifelike. The Atticus embraces this knowledge, and takes it to the next level, with clarity, a vivid mid-range, and vigorous bass. This closed headphone will take you away into a world that you may never recover from.

Aeolus:  [ˈe.o.los]

Aeolus, known as the “divine keeper of the winds” in Greek mythology, is our answer to those wanting an “open version of the Atticus.”  The Atticus, since its release, has gained a cult following for it’s detailed yet warm powerful sound. The Aeolus, keeps with this tradition with a more deft touch, bringing a slightly more linear sloped response to the table, while providing the soundstage of an open headphone.

When looking for a closed hammer-fist of glory, and a compulsively musical and vast-staged chameleon, you’ve come to the right place with the atticus and aeolus.

I was worried when everyone was calling (the Atticus) fun that they might be lacking, well they’re not. I’m hearing new details in songs I’ve listened to hundreds of times with some pretty good headphones. And I don’t just mean like, oh that sounds better, I mean like oh I’ve never heard that before in the song. Timbre is also amazing, everything sounds very accurate in tonality. As a musician myself, I noticed with most headphones, they might do one instrument really well and others sound artificial, these sound very accurate across the board.

Aeolus takes the popular ZMF Atticus and puts it in an open shell, expanding the soundscape and giving the headphone an airier feel. Fortunately, Aeolus keeps my favorite parts of the Atticus: the lush, creamy midrange and big bass impact. This is one very easy headphone to listen to, with a signature that accomplishes the rare feat of being both exciting and non-fatiguing.

The Story

I started modifying Fostex t50rp headphones in 2010 as a musical outlet I lost when moving to Chicago from New Hampshire, as the reduced space didn’t allow me to build acoustic guitars. Ultimately this led to me gifting my brother a modified t50 during the holidays. At this point, I was deep in the throws of graduate school, where I studied and taught film directing. Before I began to modding headphones, I had been immersed in building acoustic guitars. My time was spent learning from master Luthiers, obsessing over the acoustic properties of wood, and perfecting my finishing and assembling skills. To my surprise, I felt the same excitement in completing a modified headphone as I did when I finished building an acoustic guitar. Modifying headphones was also a much more reasonable hobby for apartment living than was building guitars. Over the next year, in order to feed my addiction to modifying headphones, I started selling my modifications under the moniker ZMF Headphones. I had already started an LLC as Zach Mehrbach Films (ZMF) for my course work, so why not use the corporation’s acronym for headphones?  The business started slow, with me pretty much selling the headphones for what it cost me to build them. I was not looking to get into business. Fast-forward three years later, to early 2014, and it was time to make a decision about whether or not to continue my job as an adjunct professor of film, or to go all-in with the headphone world. I took the risk, followed my passion, and now I work full time, with a small staff making headphones. I love what I do and feel like all my creative and intellectual interests are fulfilled stretched through this business.

The Atticus and Aeolus are more largely influenced by our t50rp tunings than are any of the other proprietary dynamic headphones we make. The Atticus and Aeolus feature a warm tilted tuning, which became known as the “ZMF House Sound” (slightly warm, spacious, clarity without sibilance) through our modified t50rp headphones. When finalizing the Atticus in 2016, it was hard to know if there was an audience that would be interested in a headphone with such a warm tuning. For a long time, warm tunings were taboo within the audiophile community. You could enjoy a warmer sound, but forget about admitting it if you wanted to maintain credibility on the forums! Nonetheless, we released the Atticus. It just sounded so good. The Atticus was warm, yes, but why was warm conflated with bad - who made that rule? The Atticus had an inviting nature and retention of micro-detail and clarity that was really enjoyable. At first our more neutral closed headphone, Eikon, was more popular than the Atticus, but after more listeners got to hear the Atticus magic, popularity has been dead even between the two models for most of their life-times, with the choice coming down to subjective preference. Since the Atticus’ release, many happy owners have been asking for an open headphone with the Atticus’ lush sound. I’m very excited to present a headphone that will be the perfect sonic compliment, The Aeolus.
