Firewall for Headphones Current Conditioning Unit

The Firewall for Headphones is a unique no-capacitor, no-inductor solution for today's noise-laden world. The solution’s efficient nature reveals itself immediately as an obviously lowered noise floor, and then, over time, in an ever-growing and blooming naturalness of sound quality. A cleaner, clearer picture emerges as the music’s inherent dynamics flow freely, unrestrained by otherwise ubiquitous electrical pollution. Unlike Zobel networks, the Firewall for Headphones produces no voltage difference between input and output across the audio spectrum, and, unlike transformers, does not buzz or hum, nor does it lose efficiency. It is easy to use, and provides a huge sonic upgrade. It is compatible with any headphone type except high voltage electrostats.

What does it do, and why do I need it?
This unit reduces invasive electro-magnetic noise like no other solution. If you want the purest, most musical, most deeply transparent window into your prized recordings, this unit is definitely for you. Simply plug it in between your headphone amp's 4-pin XLR output and your headphone's 4-pin cable. The Firewall for Headphones is a non-powered, passive device which acts only upon the HF noise, leaving the signal pure and untouched, protected from the detrimental audio smearing effects of HF invasive noise. This is no buzz & hum remover. Buzz & hum come from faulty parts or bad wiring schematics and are fixed by addressing those types of things directly. The Firewall for Headphones turns a great headphone listening experience into a profound headphone listening experience.

Firewall for Headphones features exotic technologies you'll never find elsewhere!
LessLoss' high end designs go well beyond anything you have ever seen on the audio market. In-house technologies such as their own developed and built award-winning C-MARC™ cable, the award-winning Firewall technology created by direct laser metal sintering, potted in hardened clear epoxy resin in wooden housings, and LessLoss' special Entropic Process conductor ageing processes all come together elegantly to create an absolute beast of a performer.

The housing is no less important, and LessLoss goes all the way!
LessLoss builds the unit around a precision milled solid brass frame. This frame is only formed on two axes to ensure that EM resonance of an enclosed metallic enclosure is not possible. This is the bane of many audiophile equipment solutions with the result that many users simply open their units' lids because they find the sound more natural. What they are doing as a result is reducing internal EM resonances, allowing much of the circuit-born emission to simply leave the confines of the enclosure instead of reflecting internally. The LessLoss solution goes many steps further, not only providing an electro-magnetically open base and top, but by strongly mating resin-infused Kraft paper composite material to all sides, bottom and top of the metallic brass frame. Due to the phenomenally quick resonance damping of this composite material, this stops even the most minute physical resonance of the enclosure dead in its tracks. LessLoss has never heard a better build material for audiophile purposes. This is truly the state-of-the-art today. Not even the bullet-proof Panzerholz technology from Germany comes close.

Input and Output
To use the Firewall for Headphones, simply connect your 4-pin XLR headphone amp's output to the 4-pin XLR input of the device. Then, connect your headphone cable's 4-pin XLR input plug to the 4-pin XLR output socket of the device.

For best results, always choose C-MARC™ Entropic Process cable.
LessLoss makes the most advanced audio cable available, and highly recommend the use of the C-MARC™ Entropic Process 4-pin XLR cable to connect your amp's output to the Firewall for Headphone's input. The difference is meaningful and you will greatly appreciate the superb results of such a combination.
