For a while now I have been seeing people talk about Custom Art IEMs, only having good things to say about them. This includes reviewers, wherein I would always tell you to take opinions from multiple people to begin with, but also paying customers who have become fans of the brand to be repeat customers over the 10+ years of it's existence. This has become all the more obvious in recent years, with Custom Art having made big moves in putting its FIBAE tech to good use, and other brands following suit and coming out with similar flat impedance technologies. This comes in handy with the FIBAE 7 Unlimited and its 7 BA driver configuration, that could have gone so wrong as with a few other IEMs tested here, and instead we end up with a set that is enjoyable to listen to, relaxing when you need it for monitoring, and engaging if you push it loud, without distortion getting in the way. The FIBAE 7 Unlimited can be a great tool for professionals just as much as an excuse to spend the money for audiophiles who want something new and rare.

Custom Art is still a tiny brand relative to most others covered here and thus it still relies on word of mouth to get going. On the plus side, this also means you get personal service and interaction from the founder of the company, who is happy to spend time to discuss your needs and also go over the CIEM road should you be so inclined. It's a boutique brand in this regard, and the fit/finish of my CIEM review samples certainly justifies the price tag. I also appreciated that the CIEM option does not cost a lot over the UIEM version for even fully customized sets, and there are certainly a lot of options to tinker with. I do recommend going with the CIEM version of the FIBAE 7 Unlimited not only for comfort that works synergistically with the overall relaxing and pleasant tuning, but also to make the most of the subwoofers handling the bass in addition to achieving a smoother treble response compared to the UIEM versions. As such, I have no qualms about recommending the Custom Art FIBAE 7 Unlimited CIEMs that have far more strengths than weaknesses and can be a product that will be truly your own for years to come.
