NiceHCK Lofty Beryllium IEM Review – If It Ain’t Stiff…

Pros — Good timbre; excellent build, high-quality cable, decent accessories.

Cons — Overall generic U-shaped sound; poor cohesion between bass and midrange; thick, slow low end compromises the overall impression; lacks treble extension; adds nothing new, Beryllium just an advertisement gimmick?

Executive Summary

The NiceHCK Lofty earphone is as middle of the road U-shaped sounding as it gets, with a thick bass, lean, sharp midrange, and lack of lower treble. But it offers excellent haptic and build.

Introduction

Iems with Beryllium drivers have been a novelty for some time. Beryllium is a rather stiff material that should deliver a tighter, faster and cleaner bass response compared to conventional dynamic drivers. We expect a natural-sounding midrange, fuller with exceptional details and texture. With the rigidity and elasticity of beryllium, the treble can be extend even further without harshness or grain, resulting in a transparent, crisp sound that is comfortable for long listening sessions (KopiOkaya).

Beryllium drivers are expensive in production and very difficult to implement properly. The two earphones that work well with this driver type are the Dunu Luna ($1700) and the Final Audio A8000 ($2000), but this comes at a price. For example, one Dunu driver allegedly costs $150 in production. So, a Beryllium iem at $240 sounds like a great deal. But will it work as expected?

KBEAR went the Beryllium route with their hyped and now discontinued “Believe” model, which, priced at $159, appeared too good to be true – and it created a loss for the company. And while some really like(d) it, I found that it did not feature the traits you’d expect from a Beryllium diaphragm.

The bass was not tight but rather thick and boomy, and the midrange was overly lean. I speculate that diaphragm was so stiff and fast that filters had to dampen it to a level so that the Beryllium character got lost. I still have a prototype that is sounding speedier than light…very aggressive.

Now, NiceHCK are trying their luck. The company stands for excellent earphone cables at competitive prices, but they also dabble in earphones and earbuds. We have reviewed quite a few of their models, which are hit and miss sonically, while always built very well.

Specifications

Physical Things and Usability

The Lofty comes in a fancy blue leather container with 2 different sets of eartips (S/M/L), a high-quality 6N OCC cable, and the usual paperwork.

The “N” number in 6N refers to degree of copper purity. 6 refers to six nines as in 99.9999% pure copper (5N would mean 99.999% and so on).  OCC stands for “Ohno Continuous Casting”. It refers to a method of copper refining developed and patented by Professor Ohno of the Chiba Institute of Technology in Japan.

The blue cable is textile coated, rather thick, and on the heavier side, reminiscent of a small rope. It has some microphonics.

The earpieces are of very high quality, too: CnC-machined airplane grade aluminium. They are a somewhat big and heavy, but they fit me well and are quite comfortable. No problems, though they could be smaller for a single DD iem. Isolation is soso, but this depends on the individual ear canals.

The tips are NiceHCK’s standard fare, there was no attempt made to harmonize tips and earpieces, which constitutes a lack of attention to detail imo. None of the stock tips worked for me sonically.

The Lofty’s low impedance and high sensitivity do not require a particularly powerful source. A phone works just fine.

Tonality and Technicalities

Equipment used: MacBook Air, iPhone SE (1st gen.); AudioQuest DragonFly Cobalt, Hidizs S9 Pro; Earstudio HUD 100, several eartips.

TL;DR: the NiceHCK is pretending to be special with its Beryllium driver but it shows a rather conventional U-shape. Its bass is slow and almost vulgar, which spoils the rest of it. You would expect a Beryllium driver to be fast.

I followed the instructions and broke the earphone in for >100 hours.

So, yes, the low end, that is always the first thing my ears record. I tried different tips: both kinds of stock tips, Azla SednaEarfit, SpinFit CP145, and generic short-stemmed wide-bores. They all contribute to slight sonic differences which remain nuances.

First, the low end does not dig deep enough, there is simply something missing, Second, the low end is not composed or focused, it is slow and therefore loose and rubbery sounding. It lacks tightness, layering, and speed and is just the opposite of what you expect from a stiff Beryllium diaphragm: thick! Nevertheless, it has a decent slam which keeps hammering fuzzy mediocrity against my eardrums.

The fact that NiceHCK supply their standard eartips does not speak for a well thought-out design. I have the best success with the SpinFit CP145 as they push the low-end slightly back…and therefore the low midrange forward….but they cannot fix the lack of speed.

You can twist and turn it as you want, that bass spoils the party (considering the price tag).

The midrange is heavily influenced by the low-end variations from the eartips. The stock tips partially congest but also rein-force the vocals and deepen the stage. The less low-end you admit by your tip selection, the more do the vocals move forward. Vocals are a bit sharp and could be fuller bodied, but you can’t get that rubbery, fuzzy character out of the vocals department, which lacks clarity.

Good that the bass balanced the upper midrange peaks, they do not introduce any fatigue to my ears but the occasional shoutiness. In summary, thick, fuzzy bass and lean, sharp midrange do not fit well together, cohesion is somewhat lacking.

And the treble?

Which treble? A sharp rolloff occurs at 5 kHz and the treble disappears into oblivion. Lower treble missing in action. Cymbals may be crisp, but the challenge is to hear them.

As to technicalities: stage is not very wide and can be deep depending on eartips used. Resolution, separation, and microdynamics are not worthy of a $240 unit, not by a long shot. Timbre is ok. The NiceHCK Lofty is just ordinary and devoid of finesse.

NiceHCK Lofty Compared

The Lofty, when run side-by-side with the $250 JVC HA-FDX1, experiences its limitations, in particular its lack of balance. The JVCs are much more homogenous sounding whereas the Lofty has a finetuning issue between its thick bass, its lean, sharp midrange, and its modest treble. Their vocals and bass simply don’t fit together. The JVCs are not congested, and offer a wider but less deep soundstage. The Lofty really brings out the JVC’s qualities.

The $60 VE BIE Pro sound flatter than the Lofty, they lack depth in comparison, also have bass problems (peak too low in FR creates a blunt kick), and are not as dynamic.

The $350 Sennheiser IE 400 PRO are the smoothest, warmest, and most inviting of the lot. And they are also much better balanced and cohesive sounding than the Lofty.

The discontinued KBEAR Believe was another ~$200 Beryllium-driver earphone, which failed my analysis based on its overly thick low end and dramatically lean midrange. I gave it away and therefore cannot compare it with the Lofty.

The $180 NF Audio NM2+ has a tighter bass than the Lofty, and also a brutally harsh 4-5 kHz peak that blows it out of any contention. Also note its much better treble extension.

Concluding Remarks

The Lofty is NiceHCK’s jump on the Beryllium bandwagon. However, its signature is a rather conventional U-shape and the sound lacks speed and fine tuning, and therefore finesse to the point that I have doubt the driver is really made of stiff Beryllium. A London record label once excelled with the slogan: “if it ain’t stiff, it ain’ worth a f…” ‘nough said.

The Lofty offers nothing new but rather takes us back 2-3 years. The broadly comparable $250 JVC HA-FDX1 is the far better option.

If the NiceHCK Lofty was an $80 iem, I would laud it for its good staging and immersive character. But considering its $240 price tag, the Lofty’s overall performance is rather unimpressive and just ordinary. But at least it it not fatiguing.

Until next time…keep on listening!
