I believe restrictions on audio streams introduced in 2013 made this impossible, and likely caused the demise of the golden ears app. Because of tunings for their own headphones there's no incentive for them to allow 3rd party equalisation, so I'm doubtful we'll ever see this again. Instead the...

  It's been a while. Sorry about that.   It's not so much 'lower treble' as slap bang in the middle of your most sensitive hearing.   Try it. +6db at 3Khz (BW 1, Q of 1.4) ) will hurt. It will force you to lower overall volume, unlike other areas of the frequency spectrum. You end up losing...

My latest tuning of the Superlux HD681F (not HD681). The major tunings are preceded by ##   EqualizerApo formatted for a straight copy and paste but check the note.   Because of the -9dB pre-amp and the -9db (coincidentally) reduction in volume at 3000Hz, this equalisation requires...

  I need to qualify that. The treble control on the clip has nothing to do with the rasping treble of the 3000Hz hump. High hats etc are much higher. So I'm suggesting the combo to temporarily solve your problem. And I forgot to mention that taking out that 3000Hz hump will result in you...

  I don't have these but I've just looked at the innerfidelity graph and you might like to try taking out the 3000Hz hump that I mentioned in my two recent posts. To flatten the hump the graph may lead you to think that -12db is needed. However, in real life, not measurements headphones, it...

While we're about it, here's my latest etymotics (HF2/3/5 with output impedance below Ohms/8 ie, clip+/zip etc or the O2).   I forgot preamping, but here I include it.   Preamp: -7  dB   Filter  3: ON  LS       Fc   40 Hz  Gain 7  dB Q 2.8 Filter  3: ON  PK       Fc   130 Hz  Gain -3.5 dB...

  Which one are you thinking of? The 1000Hz dip or the 3000Hz dipped bump?    The 3000Hz bump in etymotics and the superlux is based on audio theory and it sounds like crap. And it's not flat. You can clearly hear it. It causes both bass and treble to recede drastically. A lot of headphones...

I've been fine-tuning my superlux HD681F for a while. They are supposedly 'flat' and I suppose they are flatter than many. But like etymotics, they're still not flat.     I've yet to crack how to get the bass perfect, but I'm happy with this for the meantime.   I should add that for my...

I get emailed alerts.   I found the link. It's here.   My personal preference to the parametric EQ business is a Clip zip (or plus) and rockbox firmware. It has a higher power amp than the iphone and according to the O2 designer it's hifi while also having an etymotics friendly output...

  Those were for the HF2 so should be right for the HF5 (apart from canal resonance, of course).   I am almost certain that at the time I was using the grey/large triple flange. I didn't have them buried that deep. I found that isolation seemed to  suffer and audio was (perhaps) slightly...

...I should add, that those etymotics equalisations won't be quite on the money if you are using a high output impedance source or the etymotics are using the 70ohms resistors which, for the same reason,  cause a bass hump and treble issue.   Low output impedance sources include Iphone 3 and 4...

  I know this is an old post, but it illustrates a couple of things that I think people need to know about otherwise the accudio app and other similar apps are going to get a bad rap for bad reasons.   Disclaimer: I have nothing to do with any of these apps, I'm just an equalisation nut (see...

  My pleasure. It would be great to hear what you think of the difference. I'm sure you'll be blown away.   However, it's worth keeping in mind that these phones are very sensitive and the small amount of hiss may not be acceptable to you. If so then there are two options available to you...

hmmm, just looking around. If you do have volume issues, then I would recommend the E6 over the E5 as it has another few dbs of power. The E5 only gives you an extra 5dbs which might not be enough.

Oh yes, I forgot to explain that q and bw thing. It's two different measures of the width of the affected frequencies. On the Accudio its BW (bandwidth) and on a rockboxed clip+ or Fuze it's Q.
