Hello MBA readers! Today we’re featuring a new model from BQEYZ, the BQEYZ NI. This affordable single-driver IEM is marketed as a gaming hi-fi set—a description I’m not entirely fond of, but as I review it, I can see why. BQEYZ makes some very interesting sets, and this one stands out for its quality.

I’m not an audiophile; I’m just a guy who likes to test out different IEMs and DACs and spends a lot of time listening to music.

So I’m not going to use super technical words to review it, but I will do my best to describe it.

Tech Specs:

• Dynamic Driver 11mm ceramic-coated diaphragm (PTZ technology)
• Impedance 28 OHM
• Sensitivity 112 dB
• Frequency 5-40KHz
• Cable Length 1.2m
• Pin Type 0.78mm-2 Pin
• Modular Cable

Packaging:

The BQEYZ NI is an IEM under $50 that boasts impressive packaging for its category.

Inside, we find:

• 12 pairs of eartips (2 models)
• A quality modular cable
• Nozzle cleaning brush
• Hard Case

You can tell the quality of the product is evident from the accessories, such as the cable and eartips. The cable is incredibly high quality, and I’ve seen cheaper options on $200 IEMs, while the eartips are on a metal base. The quality of the eartips themselves is very good.

Design/Build Quality:

The BQEYZ NI has a fairly classic design. The shapes aren’t strange or particularly shaped, but the faceplates have a truly beautiful and interesting depth effect. As for the materials, they’re mostly made of dark but slightly transparent resin. What surprised me was seeing lots of ventilation holes on the shells. Similar IEMs usually have the classic hole before and after the driver, while here we also have one located on the upper part near the connector, which acts a bit like an open-back opening. I think it really helps the perception of the soundstage and amplifies the treble extension. The nozzle is the classic one seen on other BQEYZ models, I’d say medium-sized. The quality of the modular cable is worth mentioning; it’s rare to see something like this on a $50 product. I’ve seen similar cables costing $20.

Initial sound impression:

These are a single driver that’s definitely worth considering, especially considering the price. Don’t be confused by the “HI-FI Gaming IEM” description, because first and foremost, this is a very high-resolution IEM. The 11mm driver with a bioceramic diaphragm is truly astonishing in terms of transparency and its rapid transient handling. It’s been a while since I’ve heard such well-crafted trebles; the extension and clarity are typical of IEMs of a completely different price. Furthermore, the soundstage is very accurate, and with this transparency, they’re also suitable for gaming, which is why we find that word on the packaging. As soon as I put them on, I immediately noticed an explosion of detail that I hadn’t heard in a while.

Their brilliance, clarity, and resolution are truly surprising right from the start, but it’s not just a matter of well-crafted trebles; the mids are also very precise and organic, and if we focus on the musical instruments, we can see how they have a very precise position in the soundstage. Each sound is extremely accurate and separate from the next. The bass, on the other hand, is tuned to sound natural but authoritative, especially if the track requires it.

Comfort & Fit:

The Bqeyz NI is a very lightweight set, and the cable is also very light, making it very comfortable to wear in any situation. The included ear tips are of good quality, although I personally opted for some aftermarket ones as I didn’t find the included ones to seal perfectly. The shell shapes are perfectly standard, and the nozzles are perfectly average.

Tips Rolling?

As always, given the sound quality of this IEM, limiting yourself to the included ones could limit your audio experience. I used the most comfortable ones, the Divinus Velvet, which fit on anything. The included wide-bore ones are excellent and resemble the SS20 eartips.

Equipment used for testing:

Device:

• Mac Mini 2012
• Redmi Note 14 Pro 4G

Software:

• Amazon Music UHD

DAC:

• Fosi Audio K7
• Fosi Audio DS3

Final sound impression:

The hours of listening with the BQEYZ NI fly by, and I can’t help but notice how this IEM manages to be ultra-clear even at the lowest volumes. Many competitors require a certain level of volume to achieve a balanced frequency range, but in this case, even the lowest volume manages to capture the entire spectrum.

I’ve done very long listening sessions at very low volumes, and it also helps train my ears a lot. The same goes for gaming sessions: the lower the volume, the less ear fatigue you experience.

Session after session, I notice how the 11mm driver has a very fast response and handles every transient quickly. The bass is also quite fast for a DD; in fact, BQEYZ has incorporated some of the PZT technology into the NI diaphragm. The result is a dynamic driver with impressive technical specifications.

Bass

It’s not the kind of bass that bassheads will fall in love with, that’s for sure, but in terms of quality and authority, it’s no slouch. It prefers to be natural, fast, and snappy with a touch of sub-bass boost at the expense of mid-bass. Overall, it’s a mature and authoritative representation of what I would call natural bass.

Mids

The mids manage to maintain a natural and neutral tone compared to the bass. The clarity and fairly advanced position of the voices are surprising, as they do not appear completely hidden or in the background. The vocal part is clearly audible even at low volume without having to push the volume too much. They are also described as suitable for gaming, and I think they do not do badly.

Treble

Bright and detailed without being harsh? It sounds difficult, but that’s exactly what my ears hear. Somehow, this IEM manages to maintain a high level of treble without becoming difficult to listen to. The amount of air is also truly remarkable, and micro and macro details literally explode. All the instruments, like cymbals, hi-hats, and violins, sound coherent without being limited or cut off. The sparks are perfect. They are confirmed to be particularly resolute even when gaming.

Soundstage and Imaging:

Its three-hole structure plus a larger one that acts as an open-back system greatly expands the sense of soundstage, bringing the level well beyond the average of similar IEMs in the same price range. Imaging is also extremely detailed, sharp, and precise. Layering for a single driver is above average. Overall, the driver works very well. I don’t know if it’s due to the fusion of PZT and DD technology, but I really like this driver.

Comparison:

I think the only brands that could currently compete in this price range are Kefine with its various single-driver options, and perhaps even Simgot. Both manufacturers have valid offerings, but fortunately, they’re all different.

Vs. Kefine Delci or Klean

Both are excellent IEMs in this price range, but they are undoubtedly less resolute than the BQEYZ NI, which has superior technical aspects. The Delci is more V-shaped and warm, but still has excellent build quality and sound, and is less technical. The Klean, on the other hand, is slightly more technical with a brighter profile, but not on par with the latter. Both are warmer and more fun IEMs, offering a more relaxed listening experience.

Vs Simgot EG280

This is Simgot’s gaming offering, a dual driver IEM with a DD and a small planar driver. The overall sound is particularly musical and energetic. It shares some similarities with the BQEYZ NI, but is slightly less sharp and requires much more power to reach its peak. The price is higher, the standard features are more extensive, but not of better quality.

Conclusion:

Its three-hole structure plus a larger one that acts as an open-back system greatly expands the sense of soundstage, bringing the level well beyond the average of similar IEMs in the same price range. The imaging is also extremely detailed, sharp, and precise. Layering for a single driver is above average. Overall, the driver works very well. I don’t know if it’s due to the fusion of PZT and DD technology, but I really like this driver. The version with a modular cable comes with several excellent-quality accessories that allow the buyer to have a functional product without having to make any upgrades. In terms of sound, technique, and resolution, you are well above average.

Q/A:

Who is the BQEYZ NI for?

If you’re on a tight budget but want a set that can bring out every little detail, you’re in the right place. The important thing is that you can tolerate the slightly spicy treble well. They’re not harsh at all, but they go where other IEMs don’t dare.

Who should avoid the BQEYZ NI?

If you’re sensitive to treble, these might be a challenge for you. They’re bright and crystal clear, making them suitable for gaming, but that’s a misleading description. The reality is that they’re a top-quality hi-fi product with resolution and clarity that’s also suitable for gamers.

Similar alternatives to consider?

There are many options in this price range. The market is truly vast and diverse, with many brands competing in the same segment. Choosing is difficult, almost impossible, unless you base it on your personal sound preferences. I’ve compared some options above.
