I spent a little while this week trying to match the RE-400 to the flat but detailed sound of my HD650, and after some sine sweeps and listening tests I've come up with this EQ setting:

 

Using Equalizer APO (but settings can be used for any equalizer really):

Filter  1: ON  LS       Fc     100 Hz  Gain   1.0 dB
Filter  2: ON  PK       Fc     750 Hz  Gain   1.0 dB  Q  0.50
Filter  3: ON  PK       Fc    2000 Hz  Gain  -4.0 dB  Q  1.55
Filter  4: ON  PK       Fc    3200 Hz  Gain   4.5 dB  Q  2.50
Filter  5: ON  PK       Fc    8000 Hz  Gain   2.5 dB  Q  5.13
Filter  6: ON  PK       Fc   10850 Hz  Gain   5.5 dB  Q  5.23
Filter  7: ON  HS       Fc   11755 Hz  Gain   1.5 dB
Filter  8: ON  PK       Fc   14750 Hz  Gain   3.0 dB  Q  5.00

 

I am actually shocked how well EQ transforms the RE-400. I'm sure this can work just as well for the RE-600 too, as they measure so similarly. 

I was always bothered by the 2kHz emphasis of these that immediately drops at 3kHz, so I compensated for that. I added a little more sparkle at 8k and close to 11k. This helps give them a little more brightness and improved clarity. I'm sort of basing this off what I'm hearing compared to the HD650 in the mids and treble (bass sounds fine to me). Also, as this is equalized for what my ears hear, it may not translate correctly for anyone else, unless you have a similar ear shape to mine. But hopefully some of you can profit from this.

 

With this EQ, they absolutely blow the Klipsch X10, X20i, and Shure SE425 out of the water for me. It may have to do with the titanium dynamic driver clarity, as sometimes those BA drivers have high distortion. Whatever the case, I'm very pleased. 

you remove mids then add treble and bass? That's basically a v shaped EQ being applied to a n shaped headphone, if you want absolute neutrality then I think there are tons of better options to choose from. I like the 2khz bump a lot but that's not the only part of the iem that's exaggerated.

Well, I lower the bump at 2k, but then I add more at 3k to make up for it. So I guess you could say I'm shifting the mids forward in frequency a little bit. Also, 750 Hz is technically in the mids, so I'm actually raising that up only 1 dB. 

As for bass, it's also only a 1 dB low shelf boost below 100 Hz. Not that much of an audible difference really.

There's not many neutral dynamic driver IEMs out there, especially below $100.

the re400 is fairly neutral with a slight emphasis on the midrange and a treble cut. The havi b3 pro 1s were pretty balanced sounding to me

Oh, and anyone who likes tip rolling, try the tips that come with the Philips SHE3590. They are made of silicone and feel much better in the ears than the weird plastic ones Hifiman offers. Perhaps there is a sound difference? If there is, I'm not noticing much.

Hi guys, I have three questions:

Has the RE-400 cable been fixed? I've bought one of the first versions of this earphone and had to send mine for repair and its the same story with the new pair.

Secondly, I'm getting a balanced audio player soon that has a 2.5mm TRRS plug for balanced output. Do the balanced RE-600 come with a 2.5mm or 3.5mm plug?

Is the cable on the RE-600 any good? I'd hate to get stuck with a broken 200€ earphone after warranty expires.

Hi, guys!

 

Just wanna get your thoughts of those who have already tried both the RE-400 and ADV M4. Which is a better buy in terms of clarity in the mids, soundstage, treble extention and lows? Overall, which is better between these two?
