3.5mm jack is very bad quality! (or just software?)

[black_dott]

I was really hoping to get at least normal headphones output from poco x3, its a poco device, no? I've used poco f1 for 2 years now, sound output from 3.5mm jack was nice and loud (at least), im using it with blon-03 and sound is, man, i cant listen to it more than a few minutes (ear fatigue is horrible). Can't believe that anyone didn't noticed this BIG issue.. cmon i havent heard such a bad sound EVER. Tried to use xiaomi's headphone presets, equalizer, sound calibration.. not even close .. after a few days (after update) tried it once more, aaand flashback, sound is simply said non usable. NO BASS, MIDS PAINFULLY SHARP, EAR PIERCING HIGHS.

im deeply disappointed, if this ENORMOUS issue is due low quality 3.5mm jack... not just software (writing this with fisical PAIN in my ears)

as i said.. on poco f1 i didn't expected hi quality dac, and i was satisfied with sound quality and loudness, i use blon 03 earbuds (iem) and there's no bass.. and overall quality is not good... ill try some apps, maybe it will help

Might be a dumb suggestion, but make sure you're actually plugging in the jack all the way in. I've heard complaints before on other phones, and the reason was because the last 0.5mm was not pushed in. Often times cases can block the full engagement of the jack depending on the design.

tried it immediately when i heard the deference between poco f1 and this one (poco x3)..tried to install some app (beats).. nothing.Dont get me wrong, I'm not picky, just sound quality isnt there..quality is LOW, tried another pair (also iem quality) of earbuds and they sound BAD.

Didn't Xiaomi specify that the POCO X3 was HI-Res Audio certified?
I'm having doubts as to whether I should buy this phone. I want that sweet 24-bit/192kHz audio!

I'm still waiting for my phone to arrive, but this would be one of the first things I check. That said, there is a small possibility that your jack may be defective, or something else going on in the background. I've had my fair share of cheap crappy mp3 players in the past and the worst sounding DAC I've ever experienced was still passable to 99% of the general public.
This review of the Poco X3 tested the frequency response from the DAC and it looks perfectly fine.

it doesn't sound as defective, just bad.. in a comparison to poco f1's...

Can anyone try to measure with RMAA with proper sound card?

I dont know what this person tested with, but these are the usual graphs/information people are looking for.

What you described in the opening post certainly sounds as defective. The typical deviation in phone DAC quality is usually very subtle and only noticed by a very small subset of people with high end headphones. There is definitely something wrong if you are getting "NO BASS" and ear piercing highs.

Is anyone else experiencing the same?

 

[CaPicote]

That sounds like a defective unit, either that or you're VERY picky.

 

[Zasnizas]

I don't know with other people but for me the sound quality is good with punchy bass, mid is quite good I can hear it clearly and high is good and details. Overall I'm really satisfied with the sound quality :good:

 

[Rezio]

Can someone confirm the audio output quality via the jack by comparing with other devices.
Would really help me to make my buying decision ;/
