    "Great In-Ears"
    Pros - Highs are crisp. Detailed, neutral sound, adequate, natural bass and enough bass
    Cons - BASS requires a little more Body
    Its very clean sounding In-Ears.
    I am not a person requiring huge amounts of BASS but the BASS on RE0 is slightly less than I would have liked i to be...Having said that I find BASS to be quite Tight. 
    Sound Stage is average.. Instrument Seperation is quite good.
    With the Amp, for which I paid a small extra,.. it sounds even better.
     
    The White Bi-Flanges are perfect for my ears.
    Am able to have them for prolonged times.

    "Head-direct RE0"
    Pros - Low price, excellent sound especially the high frequencies
    Cons - lacks body in terms of bass
    Great IEM for it's price. Produces a very detailed, transparent sound. Not for the basshead but personally I think the bass is just adequate, not too overwhelming. I just love these phones

    "Can't do better for the money"
    Pros - Balance, transparency, treble extension, detail, speed
    Cons - Bass quantity, cable quality (cloth version)
    Housings are made of metal and are solid but the cloth version of the cable is prone to microphonics.  The jack is fairly weak and the strain reliefs aren't particularly effective.  Fit is easy as the earpieces are fairly small and isolation is just above average.
     
    Sound is excellent for the money.  Treble is more prominent than in most earphones but is never harsh and has better extension than anything I've heard, detail is excellent.  The midrange is natural sounding with little colouration and is also very detailed.  The RE-0 is light on the bass but extends fairly low with excellent speed and punch but little weight behind it. 
     
    Amplification helps improve the bass quantity, punch and speed some more and overall dynamics are improved.  They sound a little sterile without an amp but do not need one, they just scale well with the added power. 
     
    Overall sound is airy and slightly warm and suitable for a wide variety of genres but not anything bass heavy.  They are very revealing and detailed but not agressive with the detail and are quite relaxed sounding.  Transparency is excellent and the individual characteristics of the recording really shows.

    "Has no equal in this price range"
    Pros - Details, Details, Details
    Cons - Cable noise
    I was lucky and grabbed these from another head-fier for $40.  I've owned many IEM's during my head-fi roller coaster ride.  I believe the only top tier universal IEM's I have not had the pleasure of owning is the UE triplefi10 and Ortofon E-Q7.  Throw the RE0 in the mix and is clear, I mean clear that this $79 retail IEM can play with the best in most areas and exceeds in others. 
     
    Similar to the review, if you're a basshead, stay far away from these.  However, if you fancied the Phonak PFE and was wowed by their clarity and detail, the RE0 brings up a few notches.  Detail freaks, buy these now, run and cherish them.  I rank them higher over the ER4S I use to own mainly because I never could get use to them jammed so far in my ear.  If you want bass and similar clear details look at the JVC-FX700.
     
    Build quality is good.  From afar, they look very average and almost on the verge of cheap, but looks can be deceiving.  You have to hear the truth these magical IEM produce.  They deserve all the praise and accolades even at their once retail price of around $200.  I just love listening to my Pink Floyd tracks in FLAC and hear more details than before, it almost feels like magic.
     
    Even at their current price of $79, like many claims before, the are no doubt a STEAL.  And yes, they benefit greatly being amped. 
     
    If you haven't tried these, you need to.  It's hard to believe they are dynamic drivers versus highest quality BA.

    "RE-0... nice, not expensive, they work"
    Pros - generally excellent sound quality, good value
    Cons - none significant, bass is nice but very tight which may not suit everyone
    I have bought RE-0 when I was looking for some portable headphones, but didn't want anything bigger than in-ear ones. I have searched for more expensive ones when I came to RE-0. The price was 99 USD, which was less that I planned to pay. Reviews were highly positive.Since I don't travel much, for me it looked like a good value for money.
     
    Overall quality is very good. Soundwise, they are very detailed, perhaps too much :wink: I can hear things I have never heard before. Take it as you wish, I mean it in good way... Some might miss that familiar boomy bass. RE-0 bass is definitely present, but very tight, precise and clear. I don't mind that "flaw" (if you want to call it this way). Acctually with most songs I prefer it.
     
    Design is OK, everything you can expect from headphones price at 79 USD (as I write it).
     
    Comfort - RE-0 come with plenty of tips, I would suggest clear bi-flanges.
     
    Isolation is just average, sufficient in most cases, but expect some noise, especially in very noisy enviroments (transportation)
     
    I was quick decision for me. For the price, I would recommend it to everyone who seeks excellent, detailed sound for a very reasonable amount of money. The only disadvantage might be that tight bass.

    "Incredibly detailed"
    Pros - Great resolution, highs are incredible, possibly the best value in IEM's
    Cons - Microphonic cable, needs a bit of power to sound its best
    In short: I love these headphones; they are an incredible value and all head-fiers should pick a pair up. While they are not as "fun" as my Grado cans or Fischer Audio IEM's, the RE0 has a neutral sound and can easily distinguish between instruments. Cymbals and acoustic guitar sound lifelike and while the bass impact may be below average, the accuracy of the lows on the RE0 have me preferring them to the lows on my bass-centric Fischer Audio Eterna.
    These are an incredible value at 79.99 and everyone should at least consider them for their next IEM purchase.

    "Great sound but not durable"
    Pros - Great sound, AMAZING for the price
    Cons - Poor durability
    You don't need another review about how good these sound. But I had two pairs, both of which lasted only a couple of months before one ear went dead. I was keeping them wrapped around my ipod in my bag but wasn't abusing them. So either I had shocking luck or these phones are a bit fragile.

    "Hi-Fi Man Re0"
    Pros - Sound quality, range of tips, sound quality and sound quality
    Cons - Shows up poor recordings and sources
    These are easily the best earphones I've ever heard. They out-perform both of my older sets of cans. Admittedly, they're older headphones, but they're AKG and Sennheiser cans that were worth equivalent money or better than the Re0s so, to me, that's impressive!
     
    The Head-Direct and Hi-Fi Man brands are one and the same so don't be thrown by the different references. If it says Re0, it's the same earphone regardless of which brand you read on the review.
     
    The Re0s are a 9mm dynamic driver canal phone. They are a simple and plain design which belies their spectacular sound.
     
    The specs don't really jump out:
     
    1. 9mm dynamic drivers with neodymium
    2. 64 Ohm impedance
    3. 100 dB/1mW sensitivity
    4. 15 - 22,000 Hz range
     
    Sound Quality
     
    I used to work for a hi-end audio-visual manufacturer and one of the key lessons from my time there was that the first impression of an audio or visual source is not accurate. The TVs and speakers that we often go for first are the most dynamic or bright, but almost never the most accurate. These dynamic sources seem exciting at first, but will quickly become tiring. The natural, true-to-life sources seem dull, flat and boring at first, but in time our body adjusts to these (and we stop comparing them with other sources) and we discover the subtleties and balance that make them truly special. The Re0s are one of those balanced, natural sources so give them a chance when you first get them. Get to know them so they can knock your socks off when you least expect it!!
     
    The sound from the Re0s is pretty close to perfect. Detail is amazing, mids are realistic and bass is present, but never over-stated. The sound is smooth, detailed and never harsh.
     
    On first listen, I was concerned that the Re0s lacked bass. Some reviews also speak about the bass being a bit thin, but I played around with the different tips provided (5 options!) until I found the right ones. That fixed it and the bass has been beautiful ever since. Coincidentally, this happened after some burn-in time so I can't rule out the benefit of burning these in - the debate rages on!
     
    Design
     
    If there's one negative of the Re0s it's their design from a purely aesthetic perspective. In terms of fit and performance, they're right on the mark, but they look pretty cheap. That doesn't mean they aren't well put together. The bodies are metal and the rubber used in the cable is high quality. The plug is high quality and the insulation is tapered so it'll fit any source you can think of. The cable splits at a classy metal junction and the sliding ring to hold the separate L/R cables together is also metal so it's not like they actually ARE cheap, quite the opposite, but they LOOK cheap.
     
    The phones themselves are simple, black painted metal with touches of polished metal. On the back of the phones is a circular area of bare metal and the finish here looks a bit rough, but it doesn't actually effect the earphones so look past that and be pleased that the Re0s are a sleeper that no-one will be drawn to steal (unless they've listened to a pair [​IMG]).
     
    Comfort
     
    I'm a novice with canal phones, but I find these comfortable. It's important though that you find the right tips. The Re0s come with S, M & L black rubber tips and S & L twin-flange tips. Play around until you find the right one and pay attention to the bass quality. When the bass and sound isolation are best, you've got the best seal.
     
    Something to note here is that pushing canal phones into your ear can create a pressure lock of sorts in the ear canal. Not only can this be uncomfortable, it can also affect the performance of your eardrum and possibly the phone. If you feel pressure, wiggle the earphone until the pressure equalises and then judge the sound and comfort.
     
    Isolation
     
    Again, as a canal phone novice, I have no real comparison, but these block out plenty of noise when I'm on the train or riding my bike so they're good enough for me.
     
    Source Notes
     
    I was concerned when I bought the Re0s that they may not work effectively on my iPod or iPhone without amplification. They do. I love great sound, but I'm realistic about it and don't want to carry around excess equipment. The Re0s are a perfect way to achieve outstanding sound from a simple source like the iPod... BUT... you won't want to use any equaliser adjustments on basic sources (like iPods). Basic sources don't have the amplification circuits to really handle any tweaking of the sound.
     
    Before I got the fit of the Re0s right I was playing around with the bass boost on the iPod and I forgot to switch it off. Later in the week I was disturbed to hear all sorts of sound quality issues from my iPod and actually thought the amplifier circuit was giving up the ghost (it's an old pod). I suddenly realised my mistake and switched off the bass boost - perfect!
     
    The Re0s WILL show up any poor recordings and sources, but the good news is that their magnificently balanced sound means that you shouldn't have to apply modifications to the sound - just enjoy it as the artists intended.
     
    Overall
     
    These phones have everything right where it matters. They've outperformed everything I've listened to, even phones worth more $$$. They don't look flashy, but they sound spectacular (if you get the fit right). I'd recommend these to anyone.

    "Great Detail, little bass"
    Pros - Highs, Mids, transparency
    Cons - weak impact, can sound 'thin'
    I really enjoyed the RE0 for a while, but the sound was lacking bass. This happened if  it was not driven properly out of the uDac or any other amp. Straight out of the iPod, there was something 'off' and it wasn't natural. The RE0 doesn't go particularly low.
    On the other hand, the highs are excellent. So are the mids. 
    For the current price, they are a must-have.
