HiFiMan RE0 Review

Introduction

I’ve already written a great deal on the RE0s but I don’t consider any of it a formal review in the traditional sense. If you’ve read my previous writing about the RE0s, you should know that I am positively enamored by them. In the few weeks since I received them, they have quickly become my preferred listening devices when I sit down with my laptop or MP3 player and listen to music. After putting them through their paces for 200+ hours and listening to the sound signature evolve and mature in that time, I finally feel that I’m ready to give the RE0s the review they deserve. So, without further ado, read on for my full review of the HiFiMan RE0 in ear monitors.

Technical Specifications

Driver: 9mm dynamic driver
Frequency Response: 15Hz – 22KHz
Impedance: 64 Ω
Sensitivity: 100db/1mw
Cable Length: 1.2m/4ft

Packaging and Accessories


The RE0s come packaged in a small, clear plastic clamshell box. The design is unobtrusive and eye catching, showing off the IEMs flanked by the three pairs of silicone single flange tips. Included accessories range from the aforementioned three pairs of single flange silicone tips, two pairs of small and large bi-flanges, five pairs of replacement filters and a shirt clip. Overall, this is a decent accessory package but I would’ve been happier if a soft or hard carrying case had been included with the package. I guess you could argue that the case the RE0s came in could be used to carry them around in a pinch but it’s just slightly too big and bulky to fit very comfortably in a pocket.

Design and Build Quality

Right off the bat, the similarity to the V-Moda Vibes is immediately apparent. The housing is made of metal, painted black with a matte finish instead of the high-fashion polished aluminum look and feel of the V-Moda Vibes. The metal design inspires confidence in terms of long and short-term durability in that they feel sturdy and resilient without being too heavy or too light. Extending down from the casing is a long strain relief which is soft rubber in texture and adds to the durability and protects the cable as it enters the housing. The cable also terminates in a properly relieved L-plug which is new in the current revision of the RE0s.

The cable itself is fairly thick and very soft and pliable and seems durable enough to withstand a fair amount of abuse. One issue I have with the cabling of the RE0s is that they transmit a lot of cable noise. Wearing them straight down while walking or performing any kind of activity that causes the IEMs to rub against your clothing, will result in microphonic noise being transmitted into your ears. It’s annoying and distracting to be sure and using the included shirt clip and wearing them over-the-ear is practically required if you plan on walking anywhere with these.

These feel like they will be able to withstand normal amounts of daily use and abuse for a long period of time. I do wish these came with a carrying case of some kind to protect them while on the go and naturally, it’s expected that you’ll want to protect your investment. I would advise getting in a carrying case of some kind to protect them if you plan on carrying them around.

Comfort and Fit

The housings of the RE0s are very small and light and, as such, you’ll barely feel them while they’re in your ears. For me and my small ear canals, the small black tips were best for me but now, I use a pair of small tips I sourced from a pair of V-Moda Vibes which I find to be a bit softer and thus more comfortable. With all of the various eartips supplied with the RE0s, I’m sure that most users will be able to find a pair that will work for them.

Sound Quality

Let me preface this by saying that these are the best sounding IEMs I’ve ever heard. Nothing I’ve ever used comes close to matching the RE0s in terms of clarity and transparency, bass and treble extension and micro level detail. These are a highly resolving pair of IEMs and as such will be highly revealing of flaws in your source material. I would not recommend using these with 128kbps music files or any other poorly recorded music, as these will make the flaws in those files stand out so much more. On the other hand, because they are so highly resolving, they allow great recordings and high bitrate files such as 320kbps MP3s and FLAC files to shine.

The RE0s are a very neutral pair of IEMs across the board and offer very little in the way of coloration to the music being pumped through them. That’s a very good thing. These are highly transparent and allow you to hear music mostly as the artist intended, without adding any degree of warmth or coldness that isn’t actually present in the piece itself.

The midrange is fairly recessed but lively and very clear. Both male and female vocals are full-bodied and natural sounding and, across the board, instruments just sound great. The biggest strength of the RE0s is their endlessly extended and exceptionally clear and bright treble. Highs are forward and sparkle with just a touch of warmth without a hint of sibilance. These have the best highs I’ve ever heard in an IEM and should please just about anyone looking for a great high end response.

Low end response is perhaps the weakest aspect of the RE0’s sonic presentation but even then, it’s not at all bad. Bass is very detailed and natural sounding but what it lacks in is body. It just doesn’t have quite enough “oomph” to my ears and as a result makes the entire sound signature somewhat thin.  Extension is very nice, as you can detect bass notes down to 20 Hz, even if those notes aren’t particularly powerful.

Soundstage and imaging are both good as well. The soundstage is of average size and depth, with great instrument separation and decent imaging.

The RE0s don’t necessarily need to be paired with an amp, despite their relatively high 64 ohm impedance but respond very well to the extra juice. The soundstage widens a bit, separation and dynamics improve and the bass improves a bit in terms of fullness. These also respond well to amps with a bass boost feature such as the inexpensive Fiio E5 and the JDS Labs CMoy BB, which highlight the great low end detail and sub-bass extension the RE0s possess.

Conclusion

Without a doubt, these are the best IEMs I’ve ever heard. These really make my music collection come alive and are very entertaining to listen to for long stretches. They let the music sink in slowly if you’re reading a book, doing homework or anything else that requires concentration while also allowing you to tune into the finer details of the music and really immerse yourself in the music you hear. For the current asking price of $79 plus shipping from Head-Direct, you really can’t go wrong with the RE0s. While these probably won’t satisfy bass-heads (at least without a bass boosting amp), these can easily compete with IEMs three to four times their price and are an absolutely phenomenal value for the price. I highly recommend these to budget conscious audiophiles who are interested in neutral and, above all, excellent sounding IEMs.

    I own one of this earphone. But I don’t think it works well. Not because of its sound quality but because of its comfort level. When I wear it to listen to music, it just continually slips off from my ears.

    I would recommend wearing them over the ear if you’re having issues with them slipping out of your ears. Personally, I don’t have a problem with them slipping out of my ears no matter how I wear them but wearing them over the ear works well for me and may work well for you too.

    I love these headphones, with my fiio e5 they are amazing!

    I know this if off topic but I’m looking into starting my own blog and was curious what all is needed to get setup? I’m assuming having a blog like yours would cost a pretty penny? I’m not very web savvy so I’m not 100% positive. Any tips or advice would be greatly appreciated. Thanks

      Off-topic? Sure, but it’s a good question so I’ll still answer it. :)

      Getting set up on a blog like this is pretty easy but it does require a monetary investment. If you want, you can set up a blog at wordpress.com as well. While it won’t give you the same amount of freedom having your own hosting will, it will serve as a good starting platform. I used a free wordpress.com blog for over a year before I decided to start paying for my own hosting and I enjoyed it. I currently pay around $80 a year for my hosting plan from Bluehost.com and I’ve been pretty happy with them thus far (I’ve had these blogs for about one and a half years).

      I hope that helps answer your question and if you have any others, feel free to ask.
