Regarding donations and gifts:

These IRS files take time to create and any donation you make would be greatly appreciated :) However, donate by paypal does not work for the Asia-Pacific area I'm in (I live in Hong Kong). Thus the "donate to me" button doesn't work. You can however send donations to me in the form of paypal payments directly to jm_superjoe@hotmail.com :fingers-crossed:

Anyone who donates to my account will get expedited headphone irs creation as a matter of course :laugh: but if you donate $10 or more, you will receive:

1. Refit service: based on your description of the sound I can continue to tweak the IRS to tailor it specifically to your ears, including customizing resonance peak compensation according to your reports from playing with Sinegen and other tools I will talk about :cyclops:

2. (S4A-01 offer (now out of stock))

A special pair of IEMs that come with their own IRS profile:victory: out of stock due to QC problems with the supplier; only phones that checked out ok will be shipped out. Only 7 out of 20 checked ok :o

^ Previous model of gift IEMs with IRS included: Sleeper4Android S4A-01

Blurb on S4A-01 ("sold" out)

These IEMs sound wonderful with IRS applied and are an abomination to conventional wisdom in hi-fi that have 100% geek appeal and will turn the world upside down for any audiophile who was closed-minded about digital effects for music listening if they give these a listen, with and then without their custom IRS :cyclops: Basically, I have found a way to profile a pair of headphones without the $$$$$ dummy-head-with-in-ear-microphone and will be applying it to no-name cheap IEMs that have atrocious stock sound but show potential behind their warped frequency response :D

Pros and cons of the S4A-01

Limitations of the S4A-01

-dollar-store build: while I think the housing itself looks pretty good, the cable and the damping material over the nozzle leaves something to be desired, shall we say :D But it's sonically a good thing that there's damping at all over the nozzle :good:

-no packaging or accessories: to save on shipping, I shall be putting these directly in envelopes and mailing them as air mail. As far as I know they only come with the one pair of tips shown, so if these don't fit, you have to find something that does.

-isolation and microphonics: as shown in the picture, they are semi-open at the back, and do not isolate outside noises that well. I use a shirt clip with them and microphonics is manageable, but probably above average.

-supported devices only: I'll post EQ and convolver settings for use with the S4A-01 on computers, but you better make sure you are running a computer player (such as foobar2000) or an android with V4A or other supported software if you want to listen to them seriously :laugh:

Advantages of S4A-01:

-Audiophile WTF-factor: the sound difference before and after applying the V4A is just unreal. The corrected sound is not just "good for a dollar store earphone", but "good", period.

-More Audiophile WTF-factor: with V4A running, the S4A-01 will sound great while practically any other phone plugged into your android will sound atrocious. If you play a song someone is not familiar with, he may conclude that his $$$ pair of phones is having a really bad day and look at them in dismay :cyclops:

-Even more audiophile WTF-factor: for additional WTF-ness, my demo pair of S4A-01 was wired wrong so that the left and right buds are out of phase with each other. This is corrected for in the S4A-01i irs profile. If you're so lucky as to get a phase-inverted pair just like me and load this profile, every other phone plugged into your android will sound plain broken :cyclops:

-potential for improvement: though I've profiled these phones with my own ears using my patent-pending "human spectrum analyzer(tm)", I plan to ship a few pairs of these to Rin Choi, famous headphone reviewer and critic, to measure using real equipment. If and when he posts the results for these phones, I can tune them to the best new Olive-Welti sound tuning curve out there and they may sound even better than they do now :laugh:

I know this is purely anecdotal to you guys who weren't there, but I prepared these gems at a big headphone meet in Shenzhen, China and representatives from two different audio companies pegged these things at over RMB1000 (around 160USD) in value :D Which may not sound like much, but they assumed these would be Chinese-made sets selling in China, which gets a substantial markdown compared to overseas sale. And if you knew how much I actually got them for... :laugh::laugh::laugh: well me being able to mail them to you for $10 should clue you in to that :laugh:

3. You get to choose a <$10 IEM in your possession (or that you intend to buy) to be IRS profiled, whether or not measurements are available for the model. I will buy and "measure" the model as soon as I gather enough funds from donations (and have some money left over as actual donations that I can pocket :silly: Alternatively, you can arrange to have your IEMs (IEMs only please; shipping costs for any other kind is too expensive) shipped to me to be analyzed.

This is the Sleeper4Android project: to get terrific sound out of terribly cheap IEMs :D

Currently planned list of <$10 IEMs:

Philips SHE3580/3590/3595/3500 (IRS already available; 3595 has mic and one button remote)

Panasonic RP-HJE120 (HJC120 should be the same thing with mic and 3 button remote)

Awei ES-Q3 / Q3i (with mic)

-further models can be added to the list with the help of donations, donors can specify models already in their possession or that they plan to buy

List of donors S4A-01 was shipped out to (shipped on 2 August) :victory:
