A year or so ago, I made an impedance adaptor for my IEM's according to this https://diyaudioheaven.wordpress.com/headphones/headphone-attenuation-adapter/ , so that I can eliminate the hiss from the amplifier and also I can use more of the volume knob, plus it makes the audio coming from 'low...

Hello, as part of my efforts to solve the bass imbalance defect in my pair of IEM's, I am thinking of making a passive filter circuit consisting of resistors which linearly attenuates all frequencies, but with a low-pass inductor which allows the low frequencies to bypass the attenuation here is...

so i was browsing facebook and i came across this image: turns out that it was a discussion about this game called 'Blind Legend' https://m.facebook.com/factsweird/photos/a.593359597348402/5073409846009999/?type=3&source=57, although i have also known about an audio game which came out for the...

Hello people, this has been something which has been bothering me ever since I have started using personal music systems many years ago I like to listen to bass-heavy music, and I find it extremely uncomfortable when I can hear that one of the channels gives out more bass than the other, it is...

I am looking for an IEM with good noise isolation and neutral sound, other than the Etymotic ER-4 series If these IEM's have additional quality control such as channel matching between the left and right sides, it would be good too Any suggestions?

Hello everyone So I used to own a few sets of Etymotic ER4 iems over the years, mainly for their sound quality and isolation, as well as the frequency matching which Etymotic does However I like to listen to bass-heavy music and the ER4 frequency matching does not extend below 100hz ,and I can...

so it seems that I am quite sensitive to bass, particularly if there is a different loudness between left and right... I have owned a few Etymotic ER4 variants and they are only matched as low as 100 hz , and the mismatch between the channels in the 60-30 hz range really bothers me are there any...

Hello, I am the owner of a newly purchased Fiio Q1 amplifier, and on it there is a gain switch which makes the volume much louder. What is the difference between using the low gain setting and increasing the volume, and using the high gain setting and lowering the volume? I am posting this as...

Here is a picture from this post , showing the certification chart which comes with the Etymotic ER4XR Notice that the channel match for the Etymotic ER4XR doesn't extend below 100hz, and in this example there is a slightly visible difference in the low frequency region of graphs of the two...

hello people, i would like to be able to make a graph like this whenever i visit a brick and mortar audio store i have seen a few threads on head-fi concerning SPL meters and such, but i am more interested in being able to see the frequency response of IEM's i am about to buy, rather than...

Has anyone heard of these? I tried searching in head-fi but nothing came up So anyway, these things seem to be quite good value, the Klang is us$60 and i find that the sound is comparable to earbuds twice the price with a good amount of bass , upfront mids and well-defined treble, giving clear...

found via http://www.instructables.com/id/Zip-Earphones/      zipping the cables of your earphones/IEM up ... has anyone tried it?  I for one hope that it might be a possible solution to the heavy microphonics of my ER-4's , as well as maybe giving it a bit more protection when im out and about

hey guys, i love my er4's sound and isolation, but im getting kind of irritated by how much noise the cable picks up... wearing them over the ears are beginning to hurt and it only helps somewhat   recently i have discovered that the drivers can be detached from the cable, so i was wondering...

so i've just ordered a new set of etymotic glider tips, i like them for how well they fit my ears and how much isolation they give   but lately the tips have been tearing up at the 'stalk' within days of me putting them on my ER4's ... some of them are already torn while they are still in...

hey guys, I live in the United Kingdom and I own a pair of ER4-P's    the bass on the right side has decreased noticably, and I would like to send my IEM's off to be looked at by Etymotic   how do I go about doing that?

everything about these IEM's are great, except for the cable friction noise... is it possible to get these recabled with a less scratchy cable?   also, how do i proceed with a warranty claim on my pair of ER-4P's ? etymotic has not responded to my emails... I am in the UK, by the way

any of you use the etymotic glider tips? you probably find that it muffles the treble and makes the bass and mids alot more prominent... i think it is caused by the inward tapering on the upper quarter of the inner tube, because when i ripped out the foams' inner tube and glued a section of...

ok guys, i've bought myself a UM1 because is the more isolating than the UM2 or UM3 (am i right?) , and i've tried to stick a pair of Shure olives onto it... the right side slid right into it quite easily, but i dont know if the stalk of the left side UM1 housing is abit thick or the Shure...

i'm tired of smashing my IEM's to pieces, but the cases and pouches and stuff are always so cumbersome... i had an USB cable once which rolls into an enclosure, its basically a sprung and racheted spool... you'd draw the cable out as long as you need it, when you let go the rachet would...

have any of you felt a sense that can only be described as motion sickness when you try out a pair of IEM's, or just a new pair of tips? especially if it creates a strong isolation ... today i have been trying out my modified etymotic glider foams, and as i am listening to music right now i...

hey guys, are there any IEM's out there which dont fit into the BA or dynamic category?

i have been trying out a new set of tips for my Philips SHE9850 ... the difference between this pair and my previous pair, was that the new ones give a noticable vacuum seal, you could feel the pressure when you put them in and the tug when you pull them out.... so i was trying them out...

ive just had a discussion on this from another forum... IEM's , especially the balanced armature designs, have much higher decibels per watt than earbuds or headphones... most portable audio equipment and headphone amps are designed for driving things which are less sensitive than IEM's...

hey guys, heres the deal... ive just got myself a first pair of IEM's , been using full size headphones up until now.... boy are these things sensitive ... what my headphone amp to these IEM's , is like speaker amps to my headphones ... anything above a quarter of the volume and its...

i am wondering about 2 things... either low powered, really low noise amps which wont blow our eardrums or the IEM's at more than a quarter volume...it would probably cost alot, and make our current amps redundant... its either that, or a volume limiter which lets us do the same thing...
