Product Description

Mitchell & Johnson UK Re-Invent The Electrostatic Headphone; No DC Bias Amp Required! Finally. This is the Breakthrough We’ve Been Waiting For.

2-way Hybrid Electrostatic Design

Most headphones on the market today fall into one of several categories, either an Electro-dynamic, Planar Ribbon, or Electrostatic (ESL). Since the electro-dynamic speakers were first developed, they’ve dominated the market. However, knowledgeable audiophiles consider ESLs to be the Ferrari of all speaker types, with the highest quality of sound. The trick is getting them to operate over a full bandwidth, still produce great bass, and not cost an arm and a leg.  To do that required inventing a new diaphragm material that allows for the elimination of the DC Bias Charger / Amp that all electrostatic headphones still require to this day, requiring them to be plugged into an AC wall socket, making them all un-portable.

.

.

Except Mitchell & Johnson MJ2. They’re less expensive because their diaphragm is permanently charged with nano-particles so no DC Bias Charger / Amp is required. That cuts the price in half or more. “Hybridding” does the rest by combining the best 40mm dynamic woofer set in an acoustically ideal sealed wood chamber for deep, articulate bass, crossing over to the electrostatic diaphragm at about 200 Hz to deliver a perfect blend of both technologies. The result is the finest headphone I’ve heard yet, with clarity and resolution equal to the best Hi Res Audio content.  

Why professionals like electrostatic speakers

The extremely thin diaphragm of ESLs has a much lower mass than most other drivers and therefore conducts to velocity of dynamic response, meaning they’re faster because they’re lighter. They have no overhang, meaning they dont store energy.  ESLs have the absolute advantage on frequency response, both amplitude and phase, and musical transparency when compared to electro-dynamic and planar ribbon drivers. Note the specialized mounting angle of the drivers, they’re cleverly aimed into your ear canal to eliminate HRTF, Head Related Transfer Function. Wow. That’s a nice touch, none of the others thought about that.

The diagram below depicts how an electro-dynamic speaker makes sound vs the self-biased Mitchell & Johnson electrostatic diaphragm. Below that, I’ve put together a comparison chart of all the electrostatic headphones on the market with their specs and prices as published on their websites. As you will see, there is no comparison really, the Mitchell & Johnson’s MJ2 excel in every parameter and sell for an incredible $499.

    Just got mine ! And from the listening I’ve done, they do not disappoint! They are how I remember them from the headphone expo in London a few months back! Very impressed and happy ! Robert, UK Consumer, Sept 2016

    The headphones take you deep inside the song. You can hear things you have NEVER heard before. Colour me impressed and that’s after listening to 4 songs from out the box. The bass is definitely there (thank God) I am pleased it’s not totally flat sounding. Leon Everton, Audiophile Consumer, Sept 2016

    With major burn in they sound smooth, natural, and distortion free. Amazing change. Love the M&J Electrostatz! Doug Adams, Audiophile Consumer, Sept 2016

    My brother was using a straight up iPhone 6 with crappy 256k downloads from iTunes. I’m planning on bringing him along slowly so he can unleash much more potential out of his new cans. When he said that everything was better he was specifically speaking about the precision and balance. He thought the detail was astounding, particularly in the mids and highs. His tastes lean to acoustic and folk so it’s a perfect fit. Andy Sutherland, UK Audiophile, Sept 2016

    Received the headphones 4 weeks ago and after spending some hours listening music an streaming media using different dacs and other analog sources I can definitely say that it was a dramatic upgrade compared with my audio technica ath-909. Coupling them with mDSD DAC transformed the way i listen liquid music on my pcs and phones. Georgio Catena, Audiophile Consumer, Sept 2016

    :

    Impressions so far can be described in one word as exceptional. No matter what kind of music I throw at it the sound that comes out is just right, near perfect, everything’s so well balanced, rich. Almost as if it has its own dynamic equalizer, automatically adjusting to my unique preferences for each song. More to come after I rediscover more of my favorite tunes. Altan, UK Audiophile Consumer, Aug 2016

    They give layers to songs that I never heard before. I can hear the drummer hit the skins in different places on fleetwood macs the chain. That’s how sensitive they are. I feel like I’m standing next to the actual drum. Really impressed with these. Currently listening to a James Blake The Wilheim scream and it’s giving different depths to my hearing experience. I’m really impressed Noel Clarke, UK Audiophile consumer, Sept 2016

    “if like me, you dig naturally clean, forward highs, great stereo detail, and with fast bass, chances are that you’ll really dig these N501 phones. ” Nathan Wright, Headfonia, Feb 2016
