Since the beginning of April, I've been enjoying a recently discovered earphone model, the Flare Pro 2HD. I propose you a review on this model and to begin, here is a quick presentation of the brand:
Flare Audio is a young english brand that I first knew by buying noise reduction plugs from them and then earphone plugs, the "Audiophiles". They've derived their products for a few years and now offer headphones, several noise reduction plugs and even a revolutionary Hi-Fi speaker system called "ZERO". It is a brand definitely not like the others which offers very innovative products, often financed thanks to Kickstarter projects. Flare has released several earphone models in the past (R2, Gold, Pro...) and the Flare Pro 2HD is the current result. Flare is a brand that I will call a "researcher" in audio, they often file a lot of patents for their products. Here for the Pro 2HD you have several patented technologies explained on their website:
- HD Anti-Resonance technology
- HD Dual Jet technology
- HD Acoustic Lens technology
Looking for a new pair of earphones as I was left on my last pair with ISN H40, Final F4100 and a ton of tried and tested entry-level earphones like Klipsch R6i II, Cambridge Melomania, Erdre audio or Fostex TE-05 (which I liked but too fragile), I came across one or two articles talking about the Flare Pro 2HD and the previous model, the Gold (Sold for around £1000). I hesitated for a long time before buying them because they sold for £400 and then with this period of confinement, I cracked and I'm very very happy about it!
So these earphones look like this:
- The earphones are Rhodium plated and connected to a non-detachable cable of about 35 cm to 2 MMCX plugs. Then there is a female MMCX Y with a cable of about 1m which ends in a classic 3.5mm jack. All plugs are gold-plated, impedance rating 16 Ohm.
- There is a DAC/Bluetooth module with 2 MMCX female plugs that can be connected to the earphones by removing the Y jack cable with an operating time announced at 12h playing time, 150h standby time and 2h recharging time. This module has 3 buttons on its surface as well as an integrated microphone.
- The earphones are supplied in a very original and impressive packaging which contains 3 sets of 3 Flare tips, a hard storage case, a warranty extension card and various instructions.
I did not try the old models released by Flare, they also currently have an "entry-level" model the JET which are also popular and come in 3 materials, polymer, aluminum and titanium. I ordered a pair of aluminum to compare and to make it short the Pro 2HD do everything better and are more neutral, balanced and defined. JET are very good for the price but Pro 2HD are awesome ! My old earphones were the ISN H40 and I have to say that the switch to the Flare Pro 2HD was disruptive at first.
So the earphones are plated with rhodium for a very solid finish and they use a 5.5mm beryllium diaphragm. Here it's a mono driver that reproduces the entire sound. The particularity is that there is a hole on the other side of the earphone which makes it open without causing a big sound leakage nor harming the insulation.
SOUND :
The Pro 2HDs are pretty neutral overall, they remind me a little bit of the Fostex TE-05s on that point.
The medium is very well controlled, clear, limpid, there is nothing too much, everything is there and it punches! It's dry, fast and with a great release, the definition is the best heard and the timbres are just perfect.
Highs are very well balanced, full and precise without adding brightness, there is never any unpleasant sibilance or frequencies unless the recording is really bad. It's the first time I've seen this on headphones, usually the headphone doesn't go very high in the spectrum to avoid the problem, either there's a hole in this frequency band or it's unpleasant. Here the whole frequency band is there, it's crystal clear, detailed, dynamic, no aggressiveness.
The bass part is just beautiful, I think this is where Flare really stands out from the other competitors. It's very defined, dynamic and very textured. It's the best bass I've ever heard, well held, not bassy or muddy and it goes down very, very low while being very firm with perfect definition.
(For info Flare does not want to provide frequency curves, so you have to believe your ears, it changes! )
Bass is often the main problem with many audio systems, it is very difficult to get a good bass reproduction at the sound level of the original recording. Generally it is set back, or present but soft or with an emphasis between 80Hz and 200Hz and therefore causes masking effects on other frequencies without going really low and therefore you don't really feel it. Here it's perfect and moreover it's ultra dynamic which is for me the hardest to set up technically. Attention it is not for as much basshead, if your song contains a good bass with peach, a sub bass part and well you will just hear it perfectly like the rest of the spectrum simply, nothing is added and yet what an impact!
My approach in the listening of the sound consists in wanting to hear the work of an artist such as he conceived it in studio, thus I seek the most faithful listening possible what implies neutrality, musicality and especially to be able to hear the whole sound spectrum of the song and these Pro 2HD do it with brilliance. I have the sensation of rediscovering the sound present in the music that most other earphones and loudspeakers are unable to reproduce in this way, it's bluffing!
It's disturbing at the beginning to listen to music in these conditions, very neutral sound, clear but with all the frequencies in the low frequencies and great dynamics! It's very very dynamic, all the transients of the song are transcribed so be careful with the listening volume, I insist on that!
The sound stage is according to me the other remarkable part of the Pro 2HD. It's very deep and natural, contrary to the H40 in comparison, very wide too and above all very accurate on the placement of the instruments. With my ISN H40, I sometimes had the impression that the placement of the instruments in the sound space was not good, especially the kick, bass and snare drums so in fact everything that plays in the middle. I think this is due to problems caused by the multi-driver technology which causes problems with crossover, placement of the different drivers in the shell of the earphone and therefore phase. With the Flare Pro 2HD, the placement of the instruments is exactly the same as with my mixers, with much more detail, relief and definition. Compared to electronic tracks with a lot of mid and high mids, I feel that the H40s produce resonance-related distortion that I don't perceive at all on the Pro 2HD. Probably due to the anti-resonance technology of the Flare, a tuning with added brilliance on the ISN H40 and their front end. It's a subjective opinion of course and it's only based on the neutrality and depth of sound field of the Pro 2HD in comparison.
Everything sounds right, no metallic effects like with other so-called "clear" or "precise" earphones and you can hear perfectly the various natural or added acoustics on the instruments and the song in general. It feels like listening to open headphones with the passive isolation that an earphones produces, it's very special. The result is superb definition, it's full of micro details and you really understand the work of the artists and the sound engineer.
CABLE :
Well built, rather thin, quite rigid with the particularity to be detached with MMCX plugs not at the earphones but in the middle of the cable to connect the earphones to the DAC/Ampli/bluetooth Flare provided. If the cable is designed as non-detachable, it is still possible to open the earphones, this will require a perfect skill but some have already tried the experience and have installed an MMCX connector to attach a cable of their choice for example.
The MMCX plugs are therefore connected to a Y-base which ends in an unbalanced 3.5mm jack. It should be noted that cable is balanced but not the jack... At first glance it's quite strange that Flare doesn't make a detachable cable for the earphones like most of the competition does now, especially at this price. Now the cable and its attachment seem very solid so I don't worry too much about the reliability and duration of this one. So it's an oxygen free copper cable, here no silver or other "higher end" materials and that's good! Being a trained sound technician and knowing electronics, I don't believe much in "magic" materials such as silver except to justify the price of a more expensive product... Now it is certain that a well designed silver cable will be superior to a mid/bad copper cable I think Flare is a pragmatic brand with very good researchers and engineers looking for the best possible product with the best possible materials, reminding the beryllium membrane and rhodium shells. This being said, the Flare cable is not flawless, it produces quite a lot of microphonic noise, especially in the upper part of the cable after the plastic Y-base. From my point of view, an earphone of this quality should simply not produce any at all. A 100€ Fostex TE05 for example produces none at all. Now by passing the cable over the ear, the noise disappears and it even allows the earphones to be pushed deeper into the ear while being very discreet.
TIPS :
The most important thing about these earphones are the accessories and especially the tips. There are 3 categories of tips delivered with :
- Memory foam with silicone inside called "Audiophile".
- Thicker, longer and softer memory foam with silicone inside called "Everyday".
- Full silicone called "Universal".
(Audiophiles on the left, Universals in the centre and Everydays on the right).
All in 3 different sizes S, M and L for each type. Personally I have small ears with very narrow ear canals so it's a challenge to put earphones in them. With my ISN H40 which are appreciated for their fit, it is impossible for me to get a good seal that fits with the stock silicone tips. It was for this pair of H40s that I originally bought Audiophile Flare tips, after trying different brands including cp145 spinfit and a lot of memory foam. The insulation and comfort side is superb with memory foam but the sound, whether it's with cheap foam or Comply, it wasn't that at all. I often noticed a bass attenuation, a poorer definition and a narrowing of the sound field. Well the Audiophile Flare tips were a miracle for me and my ISN H40s. The sound is better, the comfort is good and the fit is incredible, I stopped putting my earphones back on every 5 minutes. I thought I had some knocks, but I'm reassured! The "Audiophile" foams have the particularity to have a silicone guide inside but not on the whole length of the tip, they are flared at the end and quite short in fact, which allows not to crush the top of the tip once in the ear and therefore not obstruct the passage of sound. The concern now is durability, you have to provide several pairs of replacement but frankly for their price they are much better performing and durable than other brands and I won't come back on silicone anymore. There are small differences in listening between the 3 types, we lose a little body with the "Universal" for example but they are a little more comfortable, the "Audiophiles" remain the most neutral and precise. They are for sale on the web site and I highly recommend them if like me you have trouble with silicone ear tips or if you want to improve your listening to your earphones. Personally it is a more logical investment, cheaper and more convincing than a new cable at 200 euros.
DAC/BLUETOOTH :
The general shape of the earphones is also well thought out, they are very easy to insert, hold well and are very comfortable. On the other hand, they protrude a little from the ear, about 0.5 cm so they are not suitable for sleeping with. The rhodium metal finish guarantees great durability and even with the cable they are very light. If we add the DAC/Bluetooth combo, we are dealing with an ultra nomadic and discreet product.
SUMMARY OF PRO 2HD :
It's a typical listening, very precise, dynamic, very deep and wide. All the frequencies are there, well balanced and the whole is very musical. Never any hissing or harshness in the sound, unless present in the original song. Now its neutral and deep signature with a full and level low end may not convince people used to clear listening with a medium often put forward and/or a rather frontal restitution. Very surprising at the beginning because I was not used to listen to a restitution of this quality, so you have to know how to tame them. It is for the blow very easy to discern an mp3 of a lossless file with this pair (without falling in the very analytical side) thus attention with the source used and its amplification. With an impedance of 16 ohm, these headphones still require a little juice to be fed because they are very dynamic and the bass goes down to 5hz. On a phone not equipped with a good DAC and a minimal amplification, the listening can be a little disappointing but the bluetooth module is there to make up for that. On my LG V30 using Tidal, I put the volume at half for a comfortable listening.
I think that if Flare does not wish to communicate curves of frequencies nor its DAC used it is to let people the care to listen to the sound of Pro 2HD and to make an opinion by themselves. In fact, some audiophiles have too much judgment given to certain components even if it means missing out on a good experience, which is a shame. Of course this is just a personal interpretation.
To do this review I contacted Flare for more information and I must say that they were very nice, listening and easy to reach. So I don't worry about the after-sales service, as a reminder, the product is guaranteed for 2 years.
The credo of Flare on this pair of earphones is :
"We believe that Flare Pro 2HD generates the highest quality sound ever heard in an earphone at any price point. In fact we are so confident of this, we are offering our first ever Sound Quality Guarantee".
Well for me the bet is won, I don't think about buying more headphones, I don't need them anymore. I even use them in sound editing and cinema pre-mixing as comparative listening. A tip, try them, Flare often makes promotions and they can be returned within 30 days.
A small suggestion would be to make like other brands, a size of XS tips for very small ears like me.
Flare had 2 versions of audiophile tips - 1 version sounded better and was way more comforable. Unfortunetely it was also extremely fragile. Current version is less comfortable, at least for me, because the foam is no longer squishable and current version make the sound a bit harsh, at least to my ears (friend of mine has no trouble with it).
I use Klim foams - they are more comfortable, sound just as good and they make the sound more smooth.
Anyhow, its best to try at least several different foams as it all depends on our specific ear anatomy. Plus the source have pretty big impact on the sound - so different foams may sound their best with different DAPs or AMPs as they can eliminate or emphesize some shortcomings.
