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

I really wanted to hate these when I bought them. I had just purchased the Pi8 but kept hearing that these were better so I bought them just so I can say I tried them. As noted by other reviewers, I was underwhelmed when I first heard them out of the box. However, I took the time to go through the personalized sound profile and it was a complete game changer. If you're trying these or have owned please do yourself a favor and take the 3 minutes to go through the personalization. Fokus, if you're reading this for some reason, you need to emphasize the need to personalize the sound to get the true potential for these. I'd bet a significant portion of the people who return these is because they leave them stock (as most audiophiles do).Onto the comparison with the pi8s. I'll focus on sound as all other aspects (ANC, battery, fit, connectivity etc) are comparable in my experience. I haven't had any major issues with either in that regard. If you are cross-shopping with Pi8, I'd say go with these for most cases. I like these more because they can do 99% of Pi8s sound characteristics but also have noticeably more (better bass). If you listen to most modern-day genres as I do (Reggae, HIp Hop, Pop, Rock, R&B) then these will cover all bases. The only one exception I'd say would be if you primarily listen to Classical, Acoustic, light rock (Cold Play, U2) then I'd say the Pi8 might be better suited primarily because it's cheaper and goes on sale frequently. From a sound quality standpoint, it also has marginally better soundstage. These will also be phenomenal for those genres as well but they are a lot more versatile sonically, which I believe is what you pay for.In the end I kept both but these are my primary with the Pi8 as backup.

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.

setting aside the firmware issues you get here and there and that emerald green (which to be fair could be your color it just isn't mine) I have an absolute blast every time I listen to these and they're by far the best option when it comes to sound for ear buds

The sound of these headphones is one of the best. However, the overall impression is ruined by the fact that the left earbud loses charge about 15-20% faster than the right one (around 20 minutes). Additionally, for some strange reason, my hearing test settings in the app sometimes disappear, which is already quite weak.

Once you're done fiddling with the eq settings to your own taste boy do these things sound ridiculous...the hype is real

The best sounding earbuds money can buy

I bought these for 480 bucks and on the box says LDAC Bluetooth 4.3. I have s25 ultra and Rex 5 can't work with LDAC 990 high quality bitrate. I think if you pay so much money it should work properly. For example I have Aviot zx1 and those are working perfectly fine with LDAC 990 even on the street and Aviot cost much less. Yes Rex 5 are a little bit better in sound quality but it's so little difference I would say about 5% or so. In other hand we have poor quality case, app looks like it was build by students, materials earbuds itselfs not feeling like it's a premium product. Anc very poor also. So it's overprice. Aviot zx1 still the best tws on the market right now

This is the rex of earphones. I was apprehensive at first since I was not yet familiar with the brand noble but damn after a listening session I have to say..... mate it was like nothing I have heard before..... the depth is a whole nother level with those crisp highs and punchy ass bass..... I can't get enough! Although the app is quite clunky and outdated I can't complain with that spotless sound and gorgeous emerald colour😆😆
