FitEar MH335DW & Private 435

The Fit

As stated above, I had hell of a time fitting the universal MH335DW into my ears. Honestly, as much as I like what I heard, I simply couldn’t stand keeping them in my ears for very long. Naturally, had they been custom-fitted to my ears, I would have no complaints. The Private 333 which I demoed were buggers, too, but my customs fit like gloves. When the dosh for my MH335DW flows inward to my wallet, I’ll prove it.

That said, FitEar earphones tend to stick out from the ear farther than other custom earphones. It’s the unique Japanese police-sanctioned connectors. They take up a lot of room.You won’t be using either phone while sleeping.

Good news on the memory wire front. While I hate all memory wire, FitEar’s implementation is better than 90% of the competition; it is soft, and relatively pliable. It is entirely usable for glasses wearers.

The Conclusion

I’ve been a FitEar fan since the days when, from my secret TMA spy chair, I cursed Headfonia’s great design and reader interaction. Things haven’t changed. I think the MH335DW is going to be FitEar’s most divisive custom earphone. Contrast is high. Well, that’s certainly true for the demo version. It’s got some similar elements to the ToGo!334, but overall, it is a starker, more exciting earphone. For the well-healed, contrast-loving audiophile, it’s a no-brainer. But if massive contrast isn’t your thing, and natural space and edges are, the Private 435 is a sure-fire hit. While I can’t believe the two came from the same company, I do believe my ears. 

Oh yes, and Anak’s.

Good night.

Back before he became the main photographer for bunches of audio magazines and stuff, Nathan was fiddling with pretty cool audio gear all day long at TouchMyApps. He loves Depeche Mode, trance, colonial hip-hop, and raisins. Sometimes, he gets to listening. Sometimes, he gets to shooting. Usually he's got a smile on his face. Always, he's got a whisky in his prehensile grip.

    Hi Nathan, you’ll only get your 335 in October? Mine only took a month in Singapore and you live in Japan too. That’s ironic. I love your mention of the iPod Shuffle to drive it though. So, at the end of the day, your choice of the 335 over the 435 was more to do with your favorite genre of music? Cheers.

      I won’t have the money until October, that is why my process is taking longer. It’s not about speed of service. The 435 really really grows on you. I found the tightness of the MH335DW to keep me for longer. But again, the demo may sound different to the final product. I am not sure.

    Another great review Nathan. Time surely flies, but I do not know how we are meant to keep up with the pace of your delivery…It’s great that there are so many products, are we nearing a top? How would the 335 and 435 compare with the Ditas for example?

      I didn’t want to compare a custom with a non-custom earphone for a variety of reasons. But also, because both models were universal demos, I can’t give exact rundowns. That said, the sound is very different. Contrast in all departments is where the MH335DW shines. The Private 435 is a much more airy sounding earphone, in some ways comparable to the Dita. But again, they use of these earphones will be custom and there is very little to really put them on even footing for fit or anything else.

      FitEar earphones look great under the light because their case works are impeccable. The Private 435 looks better when made up fully. The demo model was sort of cheaply made, which is a shame. But, thank you for the compliments.

    Do you think the 333 lose its place after hearing the mh335dw?
    I own the 333 and curious if the mh335dw is an upgrade version of it.
    What i love about the 333 is PRaT and its extremely fast note decay, Does the mh335dw has better PRaT than the 333?

      Again, I’ve only heard the demo version. I will be able to update this review in a couple of months. But, the 333 retains a more u-shaped sound and has slightly less sound pressure in the lows. They are similarly fast, though. From what I hear, the MH335DW custom sound quite different to the demo. The demo was sexy enough that I got fitted up for the custom version.

    I must say, thus far only 2 custom monitor companies have impressed me with
    -Service
    -Build Quality
    -Sound

    Some big names can’t even hit either of the 3 criterion, but FitEar is up there lonely at the top along with FutureSonics IMO. (I think these are the two companies that produce solid acrylic shelled CIEMs (with a bit of proprietary material wrt FS, but otherwise solid acrylic), but I
    could be missing out some others…)

      FitEar CIEMS are manufactured very well indeed. No company makes perfect cases, but I think FitEar are top. FS is a company that really deserves more fanfare.

    When using these CIEMs, as well as the 333s, with the iPod Shuffle 1G, is there any noticeable hiss during music playback?

      I’m sorry to be late, Lee ZH Edgar. I don’t see comments in real time and end up answering too late. Yes there is noticeable hiss through the iPod shuffle 1G. It is similar in intensity to a circa 2006-2011 Walkman. If you could stomach Walkman’s of that vintage through sensitive to semi-sensitive earphones, surely you can stomach the Shuffle 1G and FitEar Private 435 and MH335DW.

        Thanks for the reply! Well, in the end I got myself a 1G shuffle and really like it. Have a MH335DW on the way too!

          Great. I had a few set backs to the ordering of my MH335DW, all to do with housing payments. I hope to join the camp very soon. Keep me up to date on your order and enjoyment.

            Came back to read the review again and totally missed your reply!

            Hope you’ve got your own pair now, Shigzeo. Mine’s been providing many hours of enjoyment since I’ve got them. Now my only worry is that my ear canals are too small for the SR upgrade 😉

              I have a pair! But the SR upgrade wasn’t possible. Ears too small.

    which is better in sound shure se846 vs

    FitEar MH335DW ? can you make short comparison

    • Reply October 3, 2014

      ‘Better’ is entirely subjective. I only heard universal demos of the MH335, so I can’t give definitive answers to your question. I suppose if you get perfect fit, the MH335 can deliver cleaner, clearer highs, and its sound tubes are larger so there could be better air flow. But it is all subjective. Especially since SE846 is universal and its sound relies 100% on the ear tips you use.

      I love both.

    Hi, I’m looking for an endgame iem. I’m currently finding it hard to narrow down. I currently own fit ear parterre, 535 ltd J, 535 and 530.

    Some people tell me that the 846 is better than 335 dw due to its true subwoofer technology and its 8 ohms easy to drive. I would like to plug it straight out of my i phone 6 plus, even though I own the sr 71B and hpp1 and also the chord mojo.

    I heard the 435 its, fast excellent for asian female vocals. But that is discontinued and its not very versatile.

    Also with the kse 1500 out, can the 335 beat it in some departments with detail? I really want to get an end game iem. Will the 335 be able to be driven good from an i phone?

    The Parterre, for some reason, I get ear fatigue after a while, even if the volume is low. Sometimes I wonder if the frequency is so high that my ears can’t hear it or something and it slightly hurts after a half hour. Would this problem prevail in the 335.

    One last question which is slightly irrelevant, 535 is about 36 ohms, people tell me it doesn’t need an amp as its very sensitive. Others tell me that its sensitive but an i phone won’t suffice as its 36 ohms. I’m no good at physics, and was hoping if you could shed some light on that query.

    Many thanks, terribly sorry for the long post!

      Jonathan,

      Very serious questions you’ve asked. I can’t answer all because SE846 and 435 were loaners. I can say this: SE846, as much as I love it, is too _hard_ to drive. Sure, it gets loud from any source, but 8Ω puts so much stress on the output of most devices that it won’t sound as it has been tuned to sound. Most devices (even very expensive AK380 etc.) can’t put enough current into the insanely small requirements of 8Ω, reducing output to frequency issues, larger IMD and THD distortion levels, not to mention reduced stereo discernment.

      Lovely earphone. Very hard to drive. And it is so sensitive that it hisses from most sources. A Mojo should drive it mostly well, but probably not perfectly.

      I don’t know the KSE1500.

      The 335 is driven well from many sources. It is pricey, and muscular sounding with less emphasis on midrange stereo and texture detail. If you’re into vocals, it isn’t perhaps as enthralling as the 435 but it is a great earphone.

      36Ω is an easy drive for most outputs. There is a rule of eights: if median impedance is 8Ω, you need 1Ω output to drive it reliably. Divide the median impedance by eight to find the basic requirement for steady drive. 36Ω is much easier. That doesn’t tell the entire story, but it gives a good guideline. The 335 is also quite sensitive so it gets loud from any source.

    Dear OHM,

    Thank you so much for the detailed reply and sorry for the late reply. Your answer on calculating how much output required from a device is very helpful. Would you possibly know about how much output does an i phone 6 plus give?

    Also would you also recommend the 334 for vocals, as 435 is discontinued and 435 does not have as much bass quantity hence not being as versatile. Would you also know anything about the Fit ear Aya?

    Many thanks, your help has been much appreciated.
