So I installed the Hi-Res Audio sticker close to my phone's 3.5mm jack connector.

And.....OH BOY, it's like a whole different new world, I sold my D90SE/A90 combo, because this blows it out of the water. Plugged my 10 bucks IEM and it's literally sounds better than my HD800s.

But onto the review:

Bass: it's TEXTURED!! The best bass I've ever heard, it has body, goes down to like 2hz easily, my IEM shaking my while body, even my neighbor could feel the sub bass with this upgrade.

Mids: The mids became so so natural it's almost feels like the artist singing right in front of me, it's so chocolately, so unattached, separates itself from the lows and highs so well.

Highs: Probably the best part for me, my 10 bucks IEM has a but of sibilance, but it's gone, now it's sounds better than the U18T, I just only imagine how it'd sound with a better IEM, it even made my ultrasone edition 11's treble so smooth and non fatiguing.

Soundstage: With this, the soundstage of my IEM became better than the ESL-13A which is the best soundstage/imaging speaker I've ever heard, but it's just not a competition here, the Hi-Res upgrade sticker beats the crap out of the Martin Logans.

As you can se the sticker is slightly not in the center of the output, it's because my right ear is a little less sensitive than my left one, so I out it off center so I could hear balanced.

So in conclusion, this is the best audio upgrade I've ever did, and it's highly recommended, just be sure to out the sticker as close to the 3.5mm jack as possible, because it could make sounds worse if the distance is too big.

Lol that's almost as blingy as my Fiio FDX 😅

I like the FDX in gold, but I've only seen it in pics.

But what's that gaudy iem in the photo?

Lafitear LF3 Plus, ultra cheap stuff, bought it for like 10 bucks, sounds pretty good for the price, bit bassy for me, but nothing a little EQ couldn't fix.

Did it make them sound more musical, though?

Yes, absolutely, you just have to think about hard enough, and it makes it real

But are you using an audiophile internet switch?

Yeah, an audiophile switch connected to my phone via an audiophile grade 64 bit 1456KHz capable cable and a pure gold USB to Ethernet

hilarious

Have you tried the platinum Hi-Res sticker? It makes the Delta Air earphones sound like the HE-1

Oh shit, are there anY? :O

I only got this :( but now I know there are better options out there, it'll just sound shit :/

Still a better review than What Hifi

I guess, i take this as a compliment ❤️

POCO X3 Pro is a based phone until the motherboard randomly dies like they usually do.

Also do remember to disable the audio effects on it lol.

I like this phone. I heard it only affects phone to a certain mfg date, after that they're okay. It is only 8 months old, so time will tell.

I'm using Pixel Experience 13, i wiped the stock MIUI, even tho I like some of it's features, i can't stand MIUI

Ah yes, very popular kind of upgrade in many engineering circles.

Usually stickers simply add horsepower, like MOTUL or AlpineStars logo. But in this case we have a rare example of a whole bundle of upgrades crammed into one tiny sticker.

Powerful stuff.

>chocolately

It's pretty powerful, it's even charging my phone. But since someone told me that there is a platinum version of this sticker is available, idk, honestly since then, it's sounds kinda shitty :(

I swear I read that in an actual review, but can't remember where, or maybe I just saw it in a meme.

Wow! Could you, please, tell me where can I buy the sticker? Also, it will be cool if you could tell me how to identify the original one. Thanks bro! Now I am gonna hear the truth HiFi music!

I found it one of my dad's audio stuff's box :(

But there are a lots of fake ones unfortunately, they're 1:1 but they makes your stuff sounds shit :( so it's basically trial and error.

:( it seems that I am about to spend a lot money during this journey... Well, one day I could be at that high level, fortunately I have a pair of SORNY with extra baseless and pretty high unfidelity sound, I guess I am on the right track.

You could tune that SORNY with a genuine Hi-Res sticker, just try to scrape off one from a high end device like a DAC or AMP

True! I am gonna try that out!

xD this is so funny

Just be sure you don't damage the sticker, because it could cause artifacts and distortion in the sound, i made that mistake once.

If you do everything right the sound of the "Highest-Fi" will open up, and there's no way back, from that point everything without the Hi-Res sticker will sounds dull and lifeless

Hahahaha I cannot go further more xD

After this sticker upgrade you literally won't be able to go any further. Like the endgamest endgame, there's nothing after this.

Okay, I'm stop now.

I loved this.

still a good phone? the deaths are scary and I could buy it used for 150€ hm
