If you take a look inside earpads you will notice that driver is covered with dark grey, almost black, nonwoven cellulose cloth. This cloth is acoustically transparent and protects both sides of the driver from dust. Be careful not to damage it because then the dust will find its way in.

It's a little bit annoying but not damaging to the diaphragm. Even if the diaphragm is stuck to the stator, it is not dangerous to the diaphragm and it’s enough to take out the cable and short the pins on connector to discharge diaphragm and release it from the stator. We are not releasing to...

Purpose of MRI version is mainly communication with patient and noise suppression, not high quality music reproduction. Amplifier for it is custom made and definitely not satisfying any Hi-Fi standard regarding reproduction of low frequencies. I don't think that anyone buying headphones at TOTL...

This comes with some delay but I hope it will shed more light on differences between electrostatic and planar headphones. Leaving aside dynamic and ribbon headphones, planar and electrostatic headphones are very similar by nature of producing sound: both use flexible diaphragm which is moved by...

Unfortunately, international shipping is a little bit complicated now because we were forced to stop normal operation two weeks ago. We still do some shipping and delays are inevitable nowadays.

There is no any visible difference between the two. Simple way to distinguish is to use digital multimeter (they are dirty chip, you don't need fancy one for that purpose) and measure impedance between sleeve and tip or ring on TRS connector when cable is connected to LCD-4. Serial number is...

LCD-4 wood rings are made out of ebony, often with patches of lighter reddish overtones. Photo at the bottom of page is misleading, it is burl wood and we made only a couple of pairs. Although it is very nice looking it doesn't represent average production pair and it will be replaced with more...

There is no official instructions or recommendations how to do it. Leather strap is held in place by four screws and metal plate on each side. Remove screws and plates, make new holes, shorten ends not to be visible when metal plates are in place and reassemble it again. Tools for making holes...

Leather straps must be very precisely made in order to have enough slack not to touch carbon fiber headband but also not to create big gap under headband. They are hand made and sometimes not as precise as we would like it. Final visual inspection before packaging should spot problem like that...

Reason for keeping the same price for two so different models as LCD-4 and LCD-4z is just to show that these are two variations of the same transducer. Same transducer will sound differently if it is mounted in wooden ring or magnesium housing. Even different types of wood are influencing sound...

When you remove grill, wire connected to the left side is positive and wire connected to the right side is negative.

LCD-24 is in the same leaque as LCD-4z and LCD-4 because it uses same elements as other two headphones: same fluxor magnets, same diaphragm thickness and only similarity with LCD-2 is magnetic circuit. Because that means less magnets therefore the price is also lower. On the other hand, less...

No, we didn't try to determine that. We do not to rely on memory which can sometimes play tricks with you. Direct comparison and repeatability is the key to be sure that we are not hearing what we would like to hear instead of real difference.

Out of our own curiosity we experimented with various wires, isolation and braiding. The goal was not only to find appropriate cable for our products but to satisfy our own "upgradeitis" (after all, we are only human too). My personal favorite is OCC Silver with added Gold.

NASA did study in 1985 and since then some advances in cable production have been made. In 1986 it was introduced OCC (Ohno Continuous Casting) process of producing ingots for casting wires having single crystal structure. Wires drawn from such ingots have average length of copper crystals...

It's very logical: tip is plus, sleeve is minus.

Hi, which drivers are you using on Windows 7/10? I tried "EMUU_PCAppDrvFw_L6_1_30_07" on Windows 7 without success, computer just freezes if I try to access E-MU 0404.

Headphonelounge has also OCC Copper cables: http://headphonelounge.com/headphone-cables/ and they are cheaper than silver ones.

To answer question at the beginning of the thread, YES, every headphone is running on AC and only a very small number of amplifiers doesn't have capacitor at the input which eliminates any DC component of the signal. Only electrostatic headphones require DC bias to set working conditions (create...

There is no difference in connecting speakers and headphones because most of amplifiers share common ground inside the chassis and it makes no big difference whether the three wires are carrying the signal or four. It is just matter of convenience splitting ground into two separate wires leading...
