FIBAE 4 is the next logical step for Poland’s Custom Art in its FIBAE range of custom monitors. However, as with each previous FIBAE launch the company always has a very definite tuning in mind. It would be all too easy to keep a similar tuning and simply up the resolution in line with the driver count. I think a lot of people might go for that. But that’s not the CA way of doing things.

This time we are going full-on musical with a tuning that firmly established the FIBAE 4 as a potential pick for modern pop, RnB and potentially some sub-genres of EDM.

We ‘cracked open’ the FIBAE 4 for the first time last month in our First Contact feature and immediately we felt those looking to go from FIBAE 2 might want to consider FIBAE 4 as their next upgrade.

As ever price or a good value proposition is firmly on the table with a starting point of €725.00 for the FIBAE 4.

Technology Inside

FIBAE™ Technology

FIBAE™ stands for Flat Impedance Balanced Armature Earphone. This is a patent-pending design Custom Art developed back in 2016 and since then have rolled out FIBAE 1, 2 and 3 monitors with the tech at the heart of each monitor.



Flat Impedance

In summary, FIBAE promises to deliver flat impedance and phase via a series of specially designed balanced armatures to negate the problem of output impedance dependency.

Why is that important? Basically, every headphone jack as an output impedance rating that affects the tonality of your IEM to some degree. Manufacturers have taken strides to reduce this as a factor in their DAPs and amps with a sub 1Ω impedance being almost the norm.

Inductive To Resistive

However, this is not always the case. Some can range well over 1-ohm such as the original HiBy Music R6 at 10Ω and many balanced outputs come close to 2-ohms. The FIBAE pitch changes balanced armature designs from inductive to resistive in order to cancel out impedance mismatching and delivers an optimal sound no matter what jack you plug your IEM into.

Custom Design Process

Online Store

The store is a bit similar to the new Vision Ears online store and I also like the stock design options. It may not be quite as complex as the 64 Audio Store but it does have more realistic pictures and more interesting choices. I still think 64 Audio need to come out of their 3D-cacoon a little and expand their design choices a lot more.

Using the store is really nice and easy with plenty of flexibility. You can customize each individual earpiece (left or right) in terms of shell, nozzle, and faceplate. You can also put your own custom artwork and text onto your creation.

Options

Using the CA store process you are offered up to 13 different shell and tip designs. After that, you have a huge choice of up to 39 different plate designs. These range from translucent acrylic colors, to exotic woods such as amaranth as well as more modernistic tones such as carbon fiber and aluminum.



Note, like the FIBAE 1, Custom Art is not offering a silicone option with the FIBAE 4 that you can get with the FIBAE 2 and FIBAE 3. This will limit some of the options in your socket choices when designing your FIBAE 4.

Pricing

The starting price of FIBAE 4 is €725. Of course, these are custom designs so you have a little interaction with the pricing as you go along and pick out your custom design. Just remember the more you add the more you pay.

I calculated that each option cost roughly around €13 – €25 and only the basic clear shell will keep it pegged at €725. For example, amber colored shells, Zebrano plates, and the free logo will set you back around €800.

This particular design is ala carte or off the menu. I suspect the price to be close €800, perhaps a shade lower. To be honest I find the FIBAE 4 pricing to be more than reasonable, even for the premium plates. I have seen some other stores add 100’s of dollars to the price for similar plates and designs so kudos to Custom Art for keeping prices reasonably affordable.

Add-ons

Other options to the right of the screen include the cable type and socket type. Recessed will cost you an additional €10 or you can opt for the free non-recessed connector option.

Cable choices are 2-pin in silver or black free of charge or an optional silver cable with inline remote and mic for an additional €25. All cables are designed to be fully detachable. I estimate the maximum cost of a FIBAE 4 with all the premium options and the most expensive add-ons to be around €860 all in.

Accessories & Packaging

Functional

If there is one weakness in the Custom Art presentation it is the whole retail packaging. This is not unique to FIBAE 4. In fact, pretty much every Custom Art monitor comes in the exact same packaging with the same accessories stretching back to 2015 when we first started reviewing them. The competition has moved on with fancier retail packaging and more elaborated accessory line-ups.

‘Hi’

Granted the price point €725.00 may place some restrictions on the opulence of the packing. However, the black mini-shoebox, Peli 1010 hard case, and small blue soft zipper case are more functional than wow. I still love the little “Hi” support and FAQ guide pamphlet inside the Pelican container that has shades of Apple when they were more creative than today’s corporate nonsense.

Accessories

Aside from the Peli 1010 and zipper case you also get a wax pick tool and a drying pellet and your obligatory warranty card. If you happen to buy the universal version you will also receive some ear tips in varying sizes but it does mention exactly what type of tips they are. I presume silicone and, in the case of the sound signature of the FIBAE 4, I think something silicone or hybrid might be ideal.

Ear Impressions Short Guide

The impressions guide and Q&A from Custom Art is absolutely brilliant. Perhaps one of the best in the business in recent memory. It’s not just a simple do this and that but addresses all your concerns in a few simple question and answer formats.

To quote, simply because I could not say it any better myself:

Impressions have to be made from soft silicone material. Dreve, Egger and Westone brands are recommended. It is suggested to use foam or cotton swabs to protect eardrum.

Impressions have to be made past the second bend and shall include: full concha, helix, crus helix, tragus and antitragus.

Note that Custom Art do require open jaw impressions so bring a bite block to your usual audiologist to keep your jaw steady whilst open to prevent the clay impressions from poorly curing. Then it is a simple case of packing them securely and sending them to Custom Art through your favored courier.

    Hey! Two questions:

    * I’m very confused by the ranking system. Is it explained anywhere? Why decimals? Can anyone really claim to be able to distinguish between and within frequency bands at a 100-grain? Are there multiple reviewers? Since most of your reviews are in the 8s and 9s, why not re-evaluate and re-grade to a smaller scale?
    * Which CA would you say is better-suited for Heavy Metal styles, where Guitar and vocals, i.e. midrange, are critical and bass and mids need to be hard-hitting more than enhanced?

    Thanks for any insights you may have :) Most IEMs reviews seem to mention EDM or pop, very few ever mention rock or metal genres which makes it hard to truly figure-out our options…

      Please see answers below

      The rating system has been in force since 2015. We only rank the previous 12 months reviews. The scoring system is based on the US system – 7, average, 8 good, 9 world class. Below 7 and usually, it is a fail in a bad way. Smaller scale like 5? or 3? or 2? How small should we go?

      I am not sure what you mean by 100 grain. We have many reviewers.

      As per our review, if midrange is critical then FIBAE 3 or FIBAE 1. And I quote from our review to point that out.

      “On a preference level, the FIBAE 1 might be the more flexible pairing if you need your mids front and center with traditional rock and some male vocals.” (Page 3)

      “The FIBAE 3 has a more forward and cleaner sounding mids and vocal presence with a more neutral sounding mids instrumental timbre. If you like your mids and vocals stick with the FIBAE 3. ” (Page 3).

      I make many references in a lot of my monitor reviews to genres such as metal right down to the name of the vocalist given I started out in the late 80’s and 90s reviewing metal music.

        Thanks for the reply!

        I had never heard of this scale before. Why start from 0 to 10 if 7 is average?
        As for the ‘100 grain’ reference, if each numeric also has 10 decimals, on a scale of 10 you end-up with 100 grades. 0.1, 0.2, 0.3 etc… all the way up to 10. But since the scale doesn’t seem to start at 0 (if 7 is average, does the scale then start at 4), this just confused things further for me.

        And yes I had noticed you mentioned rock, which was definitely welcome :) Metal typically has different requirements to most popular rock, with vocals stepping-back (cookie monster…) and guitar stepping in. Since these occupy similar frequency range, it’s not always easy to do right.

        Ah yes for sure, forward chord riff and male vocals competing for the same space at times. Maybe one of the reasons why people turned to symphonic female metal. No chance of that happening with Arch Enemy though :)

        Ah, this is the US scoring system and the one they use here for grading exams. The UK and sometimes Euro systems work up to 7 with beyond 7 an honors degree first class. Ways of the world.
