    Hifiman IEM's: RE-400 and RE-600

    RE-800 have exactly this kind of sound, but require deep insertion or they get your typical uncompensated flat splashy treble otherwise. Of course they're expensive.

    WICH IEM HAS THE FLATTEST SOUND SIGNATURE..

    I suspect this is HRTF uncompensated measurement (other than being inaccurate on the whole), so the raised 3kHz region is mostly correct and will sound equal loudness mostly. Still, which Samsung earphones? They have magic letters + numbers naming scheme...   E.g. compare...

    WICH IEM HAS THE FLATTEST SOUND SIGNATURE..

    The chart shows the measurement was done at a few discrete points and linear interpolation has been applied. It's neither raw nor compensated nor smoothed in usual way with smoothing described. No idea what to make of it - it could hide any number of peaks.   Also Galaxy which?

    WICH IEM HAS THE FLATTEST SOUND SIGNATURE..

    No IEM is really even, so the best you can ask for is the FR to be smooth and non-resonant, so that you can easily correct it.   For instance, InEar Stagediver SD-2 is only properly cleanly smooth when equipped with Comply, where you trade a lot of rolloff for the smoothness - which then has...

    Could noise canceling headphones cause hearing damage?

    I wouldn't exactly call ANR delivering unperceived energy. The wave physics involved are quite well understood - what happens is the typical wave cancellation. The static pressure thing is essentially not being able to cancel near DC and imperfect cancellation potentially generating near-DC...

    Custom Tips For Universal IEM's Overrated?

    As a budding technician hobbyist myself I can tell you the positive-negative-positive process is very involved and I'm missing a few steps. Just making a mold with an air hole makes for a very well fitting, but slightly loose plug. Moreover the impression surface is precise enough to actually...

    [Review] InEar StageDiver 4, a high-end universal IEM!

    It seems that SD-4 is just not as much of a steal as SD-2 is or people who want to invest 650 EUR find themselves buying one of the cheaper CIEMs instead. I'm pretty sure that the more V signature will likely not respond well to Comply as SD-2 and I am pretty sure the extra clarity gain is small...

    New Custom-to-Universal IEMs: InEar StageDiver 2/3

    Hello, I've been having fun using these InEar StageDiver 2 for about 2 weeks now with direct comparison against some heavyweighs such as Spiral Ear SE-5 referec, modified Sony MH1C, modified Hifiman RE-400, RE-300, Brainwavz B2 and Philips Fidelio S2. Including against headphones - modded...

    Multi-IEM Review - 352 IEMs compared (Pump Audio Earphones added 04/03/16 p. 1106)

    In case someone is curious about Philips Fidelio S2 as I were, they're quite great, if splashy. However, it turns out it's all only in frequency response - relatively easy to follow even on a limited EQ. Fixing this issue also vastly improves soundstage, opening it up.   The fit as with all...

    Just as a reminder, these are not the best headphones ever. Just potentially the best headphones in this form factor.

    New Hifiman Flagship (together with Unique Melody): RE1000

    Someone has to get the first pair ever. Well, you might be in luck, I'm considering it. Then they get to be made and sent via post...

    New Hifiman Flagship (together with Unique Melody): RE1000

    Yes, about the only BA out there approaching dynamic driver bass quality I know is Spiral Ear SE5 and its distortion and signature leave quite a bit to be desired, esp. for the price. I wager the woofer is tweaked RE300 while full range is a further development of RE600, hopefully bit less...

    Are binaural recordings higher quality than normal ones?

      Can you render a very near source reliably using any number of speakers? Try it, it is a very hard problem. Rendering farther sources is also doubtful. Attempt a source set directly to your left, or to right. Contrary, using headphones I can localize the sources anywhere I want.   In a...

    HIFIMAN RE300a/ RE300i InLine and RE300h (hifi) Earphone launched! *Impressions added*

    QC? Fit and sound? Not really. RE-ZERO are strongly reverberant (which some might like - it can reduce in-head feel) and the bulky shells are pretty hard to nicely lodge in ears - much less comfortable than OEM RE-300 ones for sure. Very hard to mod as well. Isolation is lower. Microphonics are...

    HIFIMAN RE300a/ RE300i InLine and RE300h (hifi) Earphone launched! *Impressions added*

    Here's some last impressions: 2 months ago, the cable isolation completely hardened and predictably, soon afterwards it cracked. It completely broke near one of the earpieces a week ago. Hifiman, seriously. All your in-ears do this! Including ancient RE0, RE-272 and RE-600. About the only other...

    Are binaural recordings higher quality than normal ones?

    Stereo speakers are not quite near the target, in fact they smear localization cues quite a bit. Wavefront synthesis (and complementary large microphone array recordings) is where it's at - if you have enough speakers, and you need a lot of them.   Headphones can be much, much closer to...

    = Hifiman “Fuzzor” Mod = (Driver backwave felt damping modification)

    I'm currently modding them, so there's no HE-6 configuration just yet.   I never had any Audeze Vegan pads, but regardless, I equalize the headphone to perceptually flat or as close as possible. Formerly used Focuspad A - the hard velour pad was way too uncomfortable and sound quality was...

    = Hifiman “Fuzzor” Mod = (Driver backwave felt damping modification)

      Softness does not have a linear relationship to acoustic impedance, which is what matters. Harder pads can have trouble maintaining seal for obvious reasons and lack of seal means much lower impedance.   That said, generally a harder material is higher density, so if the seal is just as...

    Custom Tips For Universal IEM's Overrated?

    Any tip change can also change: - insertion depth, moving resonances around, which can also change their height - deeper insertion, ear canal/shell resonances go higher in frequency and flatter, until they disappear completely - due to reduced air volume remaining in ears. There are also...

    Could noise canceling headphones cause hearing damage?

    That's not the point of this thread at all. The question was specifically if noise cancelling can be worse.

    Could noise canceling headphones cause hearing damage?

    About the only way noise cancellation could cause hearing damage is if it caused consistent static pressure in the ear cup. The effects of prolonged exposure to static pressures are not completely researched. If you can detect a weird "pressure" effect, then you might be subject to it. The...

    = Hifiman “Fuzzor” Mod = (Driver backwave felt damping modification)

    HE-6 driver has linear bass and subbass down to 18 Hz at 1 cm distance. If you want a boost, I'd recommend using an equalizer instead.   The pads actually boost all bass except subbass (3 dB for Focuspads, 4 dB for pleather) which results in the appearance of a rolloff.   Velours made by...

    Thoughts on a bunch of DACs (and why delta-sigma kinda sucks, just to get you to think about stuff)

    That is true actually. Except the set of measurements used by that guy was not comprehensive enough.   Antialiasing filter design for instance, if any is present; noise shaper in sigma-delta DACs. Presence or absence of ringing in step response - not sure how audible that is, but it can be...

    = Hifiman “Fuzzor” Mod = (Driver backwave felt damping modification)

    The excess treble in HE6 is all thanks to reflections within the ear-cup and from the grille. This is why the fuzzor mod helps a lot when used with standard pads, esp. included high impedance velours, both focuspads, all versions of jergpad and of course the most with pleather. Without pads...

    HIFIMAN RE300a/ RE300i InLine and RE300h (hifi) Earphone launched! *Impressions added*

    The bass boost is unfortunately a bit too high in frequency to be called nice - it's extremely warm giving the sound a "cellar" feel and making it overly intimate. Or "backstage" if you prefer. The result sounds flat and narrow only due to the spectrum. Some people might like this kind of...
