Unboxing Experience -
Packaging & Accessories
Decent but nothing outstanding for the price. There are 2 types of eartips, one is a typical rubber eartips and the other is a stickier silicone type of eartips. The cable is a qdc connector which for the price is quite unacceptable but it works fine.
Build quality - The shell is made of a polycarbonate plastic, so it’s very lightweight, but feels sturdier compared to resin shell iems.
Design-wise, it has a clean matte black finish look with a very unique mech design that looks futuristic or like gamer peripherals
but The highlight here is the tuning knob on the faceplate. where the open dot is for the neutral tuning while the solid orange dot means it's on bass boost mode.
It has a locking mechanism feel when switching modes, so you won’t accidentally change it and it’s smooth enough that you can actually adjust it while wearing the IEMs.
And unlike most tuning switches, this one actually makes a noticeable difference.
Comfort - Comfort is honestly one of its strong points.
Because it’s very light, it fits nicely in the ear which works great for long listening sessions.
However, the shell is slightly large since it has 4 drivers, so if you have smaller ears, this might not give a comfortable fit.
Sound -
Bass - Starting with the bass this is easily the highlight.
In normal mode, the bass is more controlled, slightly above neutral, with good extension and a clean presentation.
for the bass mode, and you get a significant boost—around 5 to 7 dB—which makes it much more punchy, heavier, and more fun. () but for me it lacks that rumble of a subwoofer despite that huge increase in the subbass
It adds a lot of impact for genres like EDM, hip-hop, and pop, but it can slightly bleed into the mids depending on the track.
Midrange/Vocals - The midrange is warm and natural.
Male vocals sound full and rich, while female vocals are smooth and non-fatiguing.
It’s not the most forward or energetic midrange, it leans more towards a relaxed presentation but it sounds cohesive and musical overall.
In bass mode, the mids can get slightly thicker or warmer in the low end, but still very listenable.
When using the neutral mode, the upper midrange is very interesting where it has 2 sides of the coin here. The 3-4khz is something that deviates from the neutral tuning which gives forwardness that gives instruments like hi-hats and cymbals sound crisp and gives a better sense of width but this also means that it also highlights sibilance, where I used this to monitor my voice and hearing that it was sibilant which i tried to fix with eq, not knowing that it sounds normal with my phone speakers or other iems like the truthear reds for example.
The bass mode alleviates this a little bit because of the emphasis in the bass which reduces the perception in the upper midrange to presence region.
Overall the vocals lacks dynamic and fun which leans towards the inoffensive and relaxed tuning with a caveat in the upper end which can work with or against the song depending on how it was mixed.
Treble - Treble is very interesting where there are The dual Balanced Armatures handle the higher frequencies giving it enough resolution and detail without sounding harsh in cymbals. This may come off as a neutral to dark-neutral since it lacks extension in the air region above 10k, where there is a continous roll off pass 4khz as the upper frequency goes higher. This is a safe tuning set that is good for those that are sensitive to treble since it comes of as smooth and round.
Technicalities:
For technical performance, it’s solid for the price.
Soundstage is average not super wide, but it has decent width and depth.
Imaging is accurate for casual gaming and music listening.
Separation is good, though not class-leading, and detail retrieval leans more towards smoothness rather than sharp resolution.
Overall, it’s more about musicality than technical performance. Micro details are prioritized over macro details
Conclusion - So overall, the OOOPUS X22 is a very interesting budget IEM.
It’s not perfect the accessories and build are pretty basic—but the sound quality and tuning versatility really make it stand out.
At this price, getting essentially two sound signatures in one is a big advantage.
If you’re just starting out or want a fun and flexible IEM, this is definitely worth checking out.
