Noble Audio FoKus Rex5 True Wireless Stereo Bluetooth in-Ear Headphones with Microphone, Sound Personalization（Green）

After a long time contemplating and watching all the youtube reviews I could find, I bit the bullet, and and I did purchase the rex5.They are truly superior to anything I've ever owned. The key is to run the hearing test multiple times and pick the one that fits the style you listen to. Then I can leave the 10 band eq on flat, and just occasionally adjust the eq curve. The resolution and fine detail on these is astonishing.That being said, the bass extension is quite a bit better on Technics AZ100 pretty much out of the box. I cannot achieve to get the similar quality and resolution (of the sub bass) on anything else. Including the rex5.On AZ100 I can hear DETAILS in the bass and sub-bass range. The peaks and valleys of the sinus curve distinctively.Every other earbuds kind of "smoothes" it out.However, for some it might be a negative.I've had a few connection issues with the rex5, when the earbuds disassociate with each other. I tha case, putting them back in the case solves the issue.But these were a very few and far between to bother me too much.

Amazing sound, amazing App and amazing ANC. My new buds - nothing comes close on a wireless set. Excellent . You will not be disappointed . Get them. Find myself turning left and right often heading sounds that appear all around me but are actually the detail my other earbuds never picked up. Never believed that there was an actual break in period for earbuds but I guess it’s true. These get better with use .

The sound from these is the closest one to the wired IEMs that I have got from any other TWSes (if I compare them to Denon Perl Pro, Technics AZ100, B&W Pi7 S2, Hifiman Swanar Wireless, Sony WF-1000XM4, and Bang & Olufsen Beoplay EX). However, the first impression was not overall that good. They took some time to burn in, then a quite tricky personal sound profiling through Audiodo (took quite many attempts until it was finally OK, but this is the must do thing here since it opens the soundstage and balances hearing differences between left and right ears), and finally tweaking through EQ to get them sound as you want. But final result is well worth the effort.The app is a bit buggy as others have noted. It tends to loose the personal profile some times, but it is still applied as it is stored on earbuds and it also appears visible the other time the buds connect, so its not a showstopper at all. Also, this issue of app occasionally loosing the personal sound profile appeared only after updating the buds to the latest firmware. So this will most probably be fixed in later releases.Yes, and there is some disbalance of how battery discharges for the buds. My left goes down faster than the right with about 20% difference (when left is 20% left, right is 40%). But this is usually a case for most TWSes. Let's see how they will hold up and behave over the time (currently I have them for about 2 weeks).Overall, I am very satisfied with these, mostly because of the sound quality that is the most important thing to me.

UPDATE: I've only owned these earbuds since July, 2025. It's now September, 2025 and these earbuds, which sounded so amazing when I first received them, are already crapping out. And I can't understand why. I've done everything I can do to get them to sound like they did when I first purchased them but to no avail. The volume in the right earbud is now greatly reduced compared to the volume in the left earbud. I've tried cleaning the earbuds, resetting them, resetting my phone, in short, every troubleshooting tip I could find on the Internet and nothing has worked. I was willing to forgive the connectivity issues, which still plague this product and the mediocre noise cancellation but when the quality of the sound is greatly diminished, that I cannot abide, especially when you pay nearly $500 for what are supposed to be top of the line wireless earbuds. I'm going to try to contact the company directly to see if I can get a resolution or if they have any suggestions for fixing the problem and I'll report back. Very frustrating.These TWS earbuds are far and away the very best I've ever heard. None of the earbuds I've used in the past even come close. The sound quality is absolutely over-the-top phenomenal! You really do have to hear them to believe them. They're about as close to high end wired headphones I've ever heard. And even though I think they deserve five stars without question or reservation--they're not perfect. The noise cancellation is mediocre at best but, let's face it, you're not buying earbuds of this caliber for their noise cancellation abilities. It's all about the sound quality with these buds and on that score, they're practically flawless! And with the number of earbud tips that come with this set, getting a proper fit should not be an issue. However, the stems on these earbuds are not very long so having them stay properly anchored inside your ear could be tricky, especially if you're moving around. Speaking of which, I find the Bluetooth connectivity to be somewhat subpar. If you're just sitting down while grooving to the music, it's fine. But if you're walking around, on a treadmill, or just moving around in general, the flow of the music is periodically interrupted by momentary disconnection. It's not horrible and it doesn't happen a lot but it's quite annoying when it does. I have an iPhone 16 Pro Max btw. So why am I still giving this product five stars despite those imperfections? Because even with those irritants, these TWS earbuds blow just about every other brand out of the water when it comes to sound. And though they are very pricey, for my money, the satisfaction you get from the sound quality alone pretty much catapults these buds into a league of their own

Just buy them. Don't listen to any bad reviews. Best earbuds ever. All you’ll want to do is re-listen to your favorite music perpetually. Ever song sounds new. Wow.
