I am a systems neuroscientist who moonlights as a sound engineer in an established studio for fun + cash. Everything I present below is standard knowledge for sound engineers, but applied to audiophile topics. I encourage other sound engineers to weigh in. I hope to undercut popular descriptors...

Everything I've been hearing for the past 3 months has been biased towards the right side.  I'd say the "center" of my music is at my one o clock, and this is with all my in ear headphones, but not my denon d7000s nor my hd25's.  Does anyone else have a problem like this?   Its currently...

In procrastinating writing a research proposal I ran across this stuff on youtube.  Its a silicone polymer that sets after (i think) enough contact with air.     It comes from a kickstarter-ey company called sugru and I was just wondering if anyone has had experience with DIY molds using...

are they the same?  I need to get a mic/controller combo.

Hi headfiers,   My school is planning on sponsoring a "rave" event, and needs fitting speakers for the job. While I would consider myself well-aquainted with personal audio, concert-sized speakers are a whole different animal.    Does anyone know where I can start with renting/buying a...

I've been reading about mods that supposedly increase SQ of the ER4P by introducing a resistor to the input.  I am very confused as to how that improves sound quality.   If anything it reduces transient response, and I feel like it would resist different frequencies to differing degrees.  ...

I'm planning on DJing later this week and I was thinking about using both my USB DAC and my normal analog computer so I can premix and hear whats going on through headphones. Unfortunately there's this big issue with the sampling rates. I have no idea what it is, but as soon as I use the "dual...

Here's my review of my first pair of custom IEM's the JH5's.  Lemme know what you guys think          Intro The first CIEM by JHAudio, the JH5Pro has been a long-existing audio option for those looking for a custom fit at a lower price. That being said, lower price isnt...

I've noticed time and time again that once I import a file to itunes that the midrange consistently gets attenuated and instrumentals seem more emphasized.  My EQ is set to flat, and I'm playing my music through my macbook and fiio E17 via USB. The issue remains even when I upsample to 96000...

I just received my jh5's (finally), and I noticed that they're a tad hot on the treble. Will burn-in reduce that?  I know that burn-in can improve the sound of dynamic drivers, but I am unsure if the same would happen for BA's.

Last night i decided that I should probably replace my IEM filters. After I did, I could perceive almost no difference in SQ, save for the slightest increase in treble sparkle.  I know that these filters are stupidly expensive for the little plastic tubes they are, so I was wondering, do other...

After owning the D2000 since christmas, I'm debating whether I should shell out some dough for a set of comparable cans. I love the Denons to death, but the hot treble can be fatiguing sometimes. I've been eyeing the HD25's for a while, and they seem like a great supplement to my collection...

Has anyone tried the JH7's before?  I'm thinking of upgrading to them from my JH5's, but I'd like some input from people first. Are there any comparable IEM's for $700 that might also be better?

I bought my d2000's about a month ago and have put in about 20 hours of pink noise burnin on them, and the sibilance is still there.  It's especially annoying on vocal tracks, and I was wondering if there's a surefire way to get rid of it.  I love these headphones, but they tear apart vocals.  I...

I plan on entering the custom iem market for a set of entry level iems, and I've come along with some interesting alternative options.  Firstly, I see that many companies will reshell universal BA IEMS for something like 100 bucks.  Then I see that I can get something like the westone 4 or shure...

  From what I've heard, the reflected sound from the cups of sealed cans can interfere with the true sound quality of the sound driver, and that soundscape can be extended quite a lot by venting sealed cans.  Seeing that there are some obvious advantages to eliminating the sound reflection of...

Note, not ear nose and throat.   Does anyone out there like some good bud paired with a listening session?  I doubt I'm the only one .  I've been listening to a ton of bassnectar and pink floyd recently, neither of them ever disappoints.

I've recently been checking out some higher end cans and some (I can't remember which) contain aluminum voice coils.  This seems slightly strange, since aluminum is definitely not as good of a conductor as copper or silver, and given that the voice coil is designed to create and respond to a...

I received my fiio e17 yesterday and It had been working as a DAC through my macbook pro just fine until today.  After using its aux input via LOD and replugging it back as a DAC, everything is horribly distorted, I have no idea what happened.  I reconfigured my output as 96k/24bit and selected...

I'm a high school student who's just gotten into audiophile equipment and I was wondering exactly how different headphones differ from each other, along with what makes the ideal setup. This is purely out of boredom and curiosity.  So here goes:   1.  What properties make for an ideal sound...

My first forays into high quality consisted of only IEM's, but I've recently realized that I'm missing out, so I'm looking to buy a set of cans in the $200-$300 range.  Soundstage and imaging are the top two in my criteria, but I really enjoy a closer sound with a linear response and good bass...

I've been looking at IEM's and headphones lately as a post-SAT present to myself and I can't really seem to narrow down on a choice.  I have about 200 bucks to spend and I'm looking for a sound signature that is forward sounding, with good bass, midrange, and soundstage, with level of importance...

I've been looking into buying a JDS CMoy or a Filo E1 or E6, but I'd like some of your guys' input before I make a decision.  Im looking for something under $50 that will give me a better sound from my monster turbine gold's and ety hf5's.  I know close to nothing about the various other brands...
