Audio46's Opinion

The soundstage of the FoKus Rex5 offers a more intimate and focused presentation, with audio positioned closer to the listener rather than extending into a wide spatial field. It achieves a well-balanced low end that is powerful without overwhelming the rest of the sound signature. Many IEMs with active noise cancellation tend to overemphasize bass frequencies, but Noble Audio has struck a fine balance here. The midrange on the FoKus Rex5 stands out for its exceptional detail and tonal accuracy, and the treble preformance is both bright and detailed, offering a complementary counterbalance to the warmth of the bass. The companion app also offers an intuitive adjustable equalizer (EQ), with a sliding scale that lets users toggle between brighter and bass-forward tonalities.

Rex5: Tailored Sound for Every Listener

Noble Audio is constantly pushing the boundaries of wireless audio: from the dynamic + planar headphones FoKus Apollo, to the multi-driver wooden housed FoKus Prestige, and the xMEMS integration of the FoKus Triumph. The Noble Audio FoKus line has been all about experimentation met with universal success.

The latest addition to Noble’s TWS lineup brings a new level of personalization with Audiodo's advanced sound software. Using an intuitive hearing calibration, Audiodo assesses the user’s hearing ability to create a sound profile tailored to each ear, resulting in a truly immersive and balanced audio experience.

Who is Audiodo?

Audiodo is a group of innovators disrupting the standards of the audio electronics industry from a sound lab in the south of Sweden. Collectively they have been pushing the boundaries of Personal Sound.

Personal Sound is constantly developed to allow for new solutions and applications. The current technology departs from a simple hearing assessment. Audiodo tests your left and right ear separately through the app, calculate where and how strong any adjustments should be, and apply only the necessary changes. Voila, you can now hear like you’ve never heard before.

The technology that drives Audiodo Personal Sound™ is a non-replicable set of sophisticated algorithms and an intricate mosaic of code. But on the surface, you’ll find an easy-to-use tool that quickly and effortlessly transforms the listening experience of each and every user.

About Noble Audio

Formed by John ‘The Wizard’ Moulton in 2013, Noble Audio has been crafting some of the most impressive custom and universal in-ear monitors ever since. Noble’s first release was the highly acclaimed K-10 which quickly put Noble on the map as a brand to look out for in the audiophile world. With subsequent releases including the Encore, Katana and Khan – Noble has gained numerous awards including multiple Headphone of the Year titles.
Jim Moulton became 50% owner in 2018, and since then the two brothers have grown Noble well beyond its original audiophile IEM home. Releasing the true wireless Falcon Pro in 2020 and later the FoKus Pro TWS in 2021 to more high praise and awards, Noble proved that they can achieve greatness in the world of wireless audio too.
Noble continues to break boundaries in the world of audio, with models such as the Viking Ragnar and Ronin displaying the technological expertise and attention to detail sown by the team. In 2023 Noble launched their FoKus Prestige all-wood TWS – a first of its kind and widely recognised as the finest true wireless in-ear monitor. With more to come in 2024, Noble is a brand to watch out for.

Partial review:

Audio 46 are excellent to deal with. I was not able to get the full effect. I battled keeping the Rex 5 in my right side. Bought azla and eletech’s baroque ear tips to no avail. After seconds the right side were just resting in my ear. So disappointed, they were exactly what I wanted. ANC and without much bass influence. They are definitely worth a try if you’re pondering the plunge. Now I’m on the fence with Amadeus and Prestige. So it goes …..

Noble Audio FoKus Rex 5

So far so good. They sound good after doing the in ear testing. The fit and finish are excellent. I like that the app has 10 band EQ, 3 band EQ or do the in ear test for a personal EQ tune to your ears.

The Best Ever

For listening to classical or jazz, these are it. Fleshes out timbre like nothing else. The performers are placed right in front of you. Nice separation . Cello sounds woody, deep and textured. Incredibly musical w out being overly or artificially warm. Maybe not the MOST comfortable but not an issue either.

Worth the hype:

I’ve had almost all. For me though these are it. I lean towards more treble than bass. I like these. You really have to take the little extra time to setup correctly. It’s worth it. Sound is rich and full. Pleasant sounding. Got mine on sale here and feel okay with that price but at full price, ehh,, no. Happy listening!
