Monolith AMT Headphone - Changeable Earpads, Open Back Design, Comfort With 6‑Foot Cable and 1/4" to 3.5mm Adapter

I say this as a POSITIVE comment for the headphones: I have owned dozens of mid-to-high fi quality headphones from Sony to Grado GS3000, and these might have been the best I've ever heard. I won't go into the array of pricy headphones I've owned... CONS: Be aware of their comfort factor. They are so large and heavy, that when I have them on the smallest setting, the casual observer thinks they don't fit (and I have been laughed at when I take them to work). I have a small head and am 5'7" tall. Anyone smaller than this might not be capable of wearing them. They look ridiculous and comical. I do not believe I could wear them for 8 straight hours, but arguably nobody should with any headphones. And they are power hungry. My 800mw tube headphone amp worked, but just wasn't enough as I had the pots at 2/3 to 3/4 for casual listenting. Forget trying to power them from your smartphone... they need a dedicated headphone amp and one with power. PROS: Sound. I moved up to a Schiit solid state headphone preamp, that puts out a full 5W (you can look that up easily) and my God. Sound nirvana. I simply love them. Great bass, extremely balanced for even my old ears. They are like having a pair of full range 20-20khz speakers on your head. DESPITE the size, the sound quality and performance hits me. Every track is a joy to listen to. I would buy them again. I only knock a star because of the insane size. Is it possible to make them just a tad smaller? People of my stature can barely wear them.

Give these headphones enough power and they will sound amazing. They DO require a lot of power, and if your headphone amp is underpowered, you'll hear amp distortion as you try to get enough power to the AMTs. But once sufficiently powered, they are simply incredible.... I've broken them in gradually over the last few months and they've improved considerably... didn't sound bad to begin with, but they have blossomed over time. I used them professionally in my recording studio, and also with mobile electronics (paired with the Monolith Alex Cavalli headphone amp). Love, love, love these headphones! The sound stage is impressive, the depth and response is staggering.

Outstanding clarity and transparency, especially amazing at this price point. Sound quality is even better than most planar magnetic headphones. And they can be easily driven by most desktop headphone amplifiers. Just one flaw: the idiosyncratic nonstandard connection configuration of the 4-pin mini XLR headphone cable connectors going into the earcups. You can't use standard mini XLR alternative aftermarket headphone cables because of this - they would short out the headphone amplifier and possibly damage it.

Good headphone, excellent punch, very impressive. My favorite now. My 20 year's passions, and the first AMT with beatiful sound.
