How To Clean The Filters

If it is metal mesh, no tool is going to clean it up. However, there is still one way: Get some pharmacy grade peroxide solution (H2O2 in 3% or 5% solution), pour a little bit in a small container and dip only the metal mesh part of the nozzle in. Let the metal mesh submerges for 3~5 minutes and allow the magic to happen. Dips the metal mesh into water to rinse, then dry it up with tissue (you might need to repeat the whole process several times before all the wax is cleaned). Be sure that the nozzle is always facing down so no liquid will go into the housing. You... read more

Anatomy Of An Earphone

Strain Relief: Molded rubber or other flexible material where the cable connects to the earpiece.

A Mere Mortals Guide To Why Bose Headphones Suck

Audio newbies are often surprised to find that Bose products are not well-thought-of by more experienced audio experts. Bose's highly competent marketing and high prices lead many average consumers to believe that their products are high-quality. Friction can develop between people who've always heard that Bose products are great, and people who have explained many times what's wrong with them. In-depth enthusiasts who would start a wiki with a title like this see a need to differentiate themselves as enthusiasts. Despite falling for basically the same marketing... read more

Bioeq Rockbox

    BioEQ for Rockbox is a fascinating EQ setup designed with the iRiver H140 originally in mind. The files have been given to me, FLACvest, by HiFlight. I first heard of this EQ from Dr. Xin Xin’s Cool Talk massage boards back in the day when Head-Fi was new and I was trying to figure out what the heck an operational amplifier was. I have since adapted BioEQ to sound good on the Sansa Fuze; I suspect it will do wonders for iPods and other devices.      The key feature of BioEQ is the design of the low shelf; peak filters 1, 2, and 3; high shelf filters, their Q... read more

Information Sonic Differences Between Dt770 Dt990

  Hi All,   This is Zombie_X chiming in here. I have started this large information thread to help those who want a beyerdynamic headphone, but do not know what they sound like and or trying to pick one to suit their set-up. Since I have heard all of the models from 32Ohm-600Ohm's in their current production line, I thought I'd make this thread.   I thought for once and for all I would do something about the abundance of threads regarding sonic differences between all the DT770, DT880, and DT990 models at all impedances. This thread will be the most... read more

Headphones I Own In Order Of Preference

      This is a review of the 20 best headphones I currently own with some added stuff at the end.  I made the choice to review both full-size and IEMs in this comparative review.  I was originally going to make this just a wiki, but as I put more and more effort into it I started to want to share it in the forum.   Very briefly I want to clarify a few things: My home rig is the MSB Platinum DAC iii and the amps I use are the TTVJ Millett 307a as well as the Larocca PRII MKii.  I've had the fortune of also auditioning most of these headphones on the Apex... read more

What Makes An Audiophile

I thought this was incredibly well said, so I'm putting it here: Quote: Originally Posted by PANGES  In my opinion, an audiophile is anyone who can appreciate sound quality. Isn't that really why we're here in the first place? To find headphones that have the particular sound quality that best suits our tastes?   By definition, the word audiophile: audio refers to sound and phile refers to love or being passionate for. So if you're an audiophile, you should just love sound or appreciate good sound quality.    I personally don't... read more
