Disclaimer: The Whizzer HE-01 was provided to us at no charge by Whizzer, however thoughts and opinions are entirely my own.

Whizzer Audio is a company that has been around for some years now and some may remember their pioneer releases such as the A15 and A15 Pro and most would have heard about the Whizzer HE03 that was a hit some time back. Based on the pricing and positioning, it seems like the HE01 serves as a more affordable option for the HE03 while maintaining the strengths of its older brother.

Accessories and Build Quality (Score: 8.5/10)

IMG_6595-1024x658.jpg

To be honest, the packaging and overall looks of the HE01 feels really prestigious and fancy which I was not expecting at this price point. During unboxing, it really felt as if I was unboxing a jewellery box due to the matte black design as well as the perfectly machined cutouts. The cable and the shell of the HE01 seem really polished, premium and aesthetically pleasing to the eyes which is a good sign and a pretty solid plus point here.

Moving on to the accessories, the HE01 comes with 2 sets of ear tips, a nice matte black carrying case that matches the rose gold colourway of the HE01 really well. Accessories wise, I think they got the usuals covered nicely but with a touch of finesse in almost everything in the package and that is really nice to see in this price bracket.

Fit (Score: 6.5/10)

IMG_6617-scaled.jpg

Now the fit is quite tricky, the HE01 just can't seem to fit in my ears nicely which perry did not encounter and that lead me to conclude that it might just be my ear shape. Aside from that, the corners are nicely smoothed out, there are no sharp edges that could prick your tender ears and also, it follows the contours of your ear relatively comfortably. I'm not saying that it has a bad fit, but it might just be me instead of the IEM itself as I also checked other reviews that did not report any obvious design flaws regarding its fit.

Bass (Score: 7.0/10)

Like most dynamic driver transducers, the bass response has depth, good punches, and great impact. It is slightly emphasised but at the same time not overly done such that it becomes sluggish and filled with bloat. The level of clarity and definition displayed here is somewhat okay for something at this price range with hints of bleeding accompanied by its size. Last but not the least, its sub-bass response fills up the empty gap below while steering clear from the extreme mud pools of bass flops. A good balance, but I do wish that the HE01 could handle the bass definition and separation here a little better.

Mids (Score: 8.0/10)

The mids sound broad with a good feel of space and clarity in its overall presentation which I enjoyed greatly. As per many other IEMs, there are some upper mid-range boosts, making it more forward and peaky with the female vocals than the counterparts that sound comparatively recessed. Not really a negative but more of a more female vocal-centric piece that takes the limelight of the stage as compared to the entire piece.

Treble (Score: 7.0/10)

The HE01 is free from any sibilance but comes up short regarding extension and technicalities. It does not sound splashy or undefined but takes a relatively laid-back approach compared to its mid-range and bass. In some tracks, while I could follow the high-hats and ornaments, they are presented relatively backwards as compared to their vocals. While I wished that the treble could have been more extended and balanced out, its treble response may appeal to those looking for a less-treble set to suit their moods.

Overall

The HE01 is a warm-sounding unit with a slight edge to its vocal presentation and bass presence. It also does have a slightly enhanced soundstage which is good but loses some points on detail retrieval. Tuning wise, I think the HE01 can handle most genres with ease except for very bass-heavy tracks it may sound bloaty and it is not doing any favours to the overall presentation being already warm.

Comparison

VS QoA Vesper Review here

This image has an empty alt attribute; its file name is IMG_4843-1024x683.jpg

The HE01 is the warmer set with some boosts to its mid-bass and upper-midrange whereas the Vesper has its focus on its sub-bass and upper-midrange. To me, the Vesper sounds more balanced and has a better detail retrieval ability whereas the HE01 shines more with its soundstage and a pleasant warm presentation of soundtracks. The Vesper in this case will be able to handle more genres as compared to the HE01 where it might sound bloaty depending on the track. Fit/Build/Package wise, I felt the Vesper has a better fit but the HE01 nails the others better with its fancy packaging and a certain kind of aesthetic appeal.

At the end of the day, I lean towards the Vesper given its versatility and superior fit as compared to the HE01 which had given me problems whenever I try to attain that seal every time I listened to it.

Conclusion

IMG_6603-scaled.jpg

Whizzer did a good job in creating something that is somewhat affordable with a great value proposition when considering the entire package itself. It is tricky to come up with a warm-sounding IEM as it has to not sound too bloaty or muddy and I am certain that the HE01 is a good example when it comes to tuning these warm-sounding sets. All in all, it is still a very competent performer with loads of aesthetic appeal to buyers out there who are looking for something fancy and well-tuned.

Overall Grade: B​

DISCLAIMER

I would like to thank Whizzer for providing this review unit. It can be gotten here: https://www.aliexpress.com/item/1005001731358565.html


EXECUTIVE SUMMARY

The Whizzer HE01 features a warm mild V shaped tuning, and is an all rounder single DD set that scores good marks in tonality, timbre and technicalities. Transients are a particular standout on this set. Accessories and haptics are nice and I would say it is one of the standout sub $100 CHIFI single DDs of 2021.


SPECIFICATIONS
  • Driver configuration: metal composite moving coil unit with high magnetic circuit
  • Frequency response: 15 hz – 40 kHz
  • Impedance: 18 Ohms
  • Sensitivity: 112 dB SPL / MW
  • Cable: 2 pin
  • Tested at $79.99 USD


ACCESSORIES


Other than the IEM, the Whizzer HE01 packaging comes with:
  • 5N OFC oxygen free copper cable – well braided, very usable OOTB sonic wise. No microphonics. Only thing to note though is that the 2 pin connector here is round and protruding for the housing. So it may not fit all aftermarket cables.
  • Silicone ear tips – I find the narrow bore eartips tend to boost bass, the wider bore ones tend to boost the upper mids/treble, YMMV as we have different ear anatomies.
  • Round metal hard case
  • Cleaning tool

Accessories wise, this is rather generous for a budget single DD, I’ve definitely seen worse in some more expensive CHIFI “flagships” (cough cough TRN). Everything is rather usable OOTB, so no need to mess with getting aftermarket tips and cables (which can add to costs).

d34658b8-c2d9-429e-b6d9-bf8289d1ba5b.jpg



For the purposes of this review, the stock cable and tips were used, so as not to change the sound signature with aftermarket gear. In particular, the narrow bore eartips were used for this review.


BUILD/COMFORT

The Whizzer H01 shell is made of plastic and is very light and well fitting. Comfort is top notch, I’ve used this set for marathon listening sessions without an ounce of discomfort.

I didn’t find any driver flex for myself (but YMMV once more as this is somewhat dependent on ear anatomy and types of ear tips used).

I liked that the Whizzer HE01 uses 2 pin connectors, as I’m not a fan of MMCX connectors in general, as they tend to have shorter longevity especially if cables are swapped too much. Only thing to note though is that the 2 pin connector here is round and protruding for the housing. So it may not fit all aftermarket cables, so just a point to note.

The Whizzer HE01’s shell is also quite beautiful looking, my wife would usually glare at me or nag when a new IEM comes in the mail. But this time, she took a look and was quiet for a few seconds. Then she grudgingly said she “wouldn’t mind trying it” LOL. But of course for us in this hobby, most of us value the sound over the looks, so let’s dive into that below.


ISOLATION

The Whizzer HE01 has above average isolation. Not too bad considering it is vented, though some pure BA type IEMs without vents will beat it in the isolation department.


DRIVABILITY

I tested the Whizzer He01 with a Khadas Tone Board -> Topping L30 amp, Sony NW A-55 DAP (DMP-A50 FEv2 Classic Mr Walkman Mod), smartphone, Shanling Q1 DAP, Tempotec Sonata HD Pro, ESS ES9280C PRO DAC/AMP, and a Khadas Tone Board -> Fiio A3 Amp.

At a sensitivity of 112dB/mW, the Whizzer HE01 is easy to drive, but like most other single DD types, it scales with amping. Amping can increase dynamics, soundstage and perhaps microdetails, but no biggie if you do not have an amp on hand with the Whizzer HE01.



SOUND & TECHNICALITIES

In a nutshell, the Whizzer HE01 features a warm mild V shaped tuning, and is an all rounder single DD set that scores good marks in tonality, timbre and technicalities.

For the bass department, the Whizzer HE01 is not a basshead set in terms of quantity, but bass is definitely north of neutral with a great punch in the midbass. Midbass is more pronounced than the subbass, but this set can still extend quite well in subbass extension. Bass quality wise, while there isn’t marked midbass bleed, the bass isn’t the most textured and can be one noted at time, but that’s something I can close one eye considering the rest of the tonality is quite good.

Lower mids are midly recessed, not overly so. Upper mids are at the borderline of spiciness for me for some songs, but otherwise, it doesn’t really get into very banshee shouty territory (cough cough Moondrop SSR) unless one jacks up the volume a lot (Fletcher Munson curve), or on some poorly recorded materials. Mids are very clean and transparent.

Treble is well extended, though there’s mild instances of sibilance. Microdetails are well captured and cymbals ain’t splashy or unnatural.

Technicalities are very good for a budget single DD, soundstage is definitely above average to good in height, depth and width. Clarity, imaging, instrument separation and details are really quite good considering it is a single DD set. One thing that stands out immediately are the very fast transients. Music never sounded congested on the Whizzer HE01 even with complex pieces.

Timbral accuracy is good as per its single DD roots, no complains for this department, it would do well with acoustic instruments and vocals in terms of timbre.



COMPARISONS

Here are some comparisons with some well regarded single DD types below. As hybrids/multi BA have their own strengths and weaknesses compared to single DD types, they were left out of the comparisons.


BLON BL-03 ($25 USD)

The legendary BLON BL-03 is a harmanish set with a midbass bump, boasting superb tonality and timbre at the sub $30 USD region. Compared to the Whizzer HE01, the BLON BL-03 is more analoguish with a thicker note weight and a more nebulous and boomy midbass.

In terms of timbre, the BLON BL-03 shades it a bit, but the Whizzer HE01 beats the BLON BL-03 in accessories, fit, isolation, soundstage, transients, imaging, instrument separation, clarity and details. Basically the Whizzer HE01 is a few levels above the BLON BL-03.

I know they are at different price brackets, but the BLON BL-03 is sort of a milestone CHIFI single DD which many folks have, and I’m sure some would ask for A/B comparisons. But actually, the BLON BL-03 may be closer to $40 – 50 USD if aftermarket tips/cables are factored in to secure a better fit for the BLON BL-03’s atrocious fit with the stock accessories, whereas the Whizzer HE01 is ready to go OOTB, no need to mess around with aftermarket gear for it.


BLON BL-05S ($39 USD)

The BLON BL-05S is a U shaped set. Unfortunately, it comes in a gaudy green colour, which may be a dealbreaker for some (in fact, I got stared at when I tried using it on the subway, so it stays at home nowadays). I’ve had some audiophile friends who refused to buy it, cause of the colour, and also cause they were burnt by the not so stellar BLON BL-05 (non S), which was quite shouty in the upper mids.

Comparing the 2 sets, the BLON BL-05s has worse accessories. The BLON BL-05S is slightly shoutier in the upper mids than the Whizzer HE01. In terms of technical performance the Whizzer HE01 is slightly better, in terms of soundstage, clarity, details, imaging and instrument separation. Once again, they are at different price brackets, and the law of diminishing return kicks in, so the Whizzer HE01 is not 2 times better as the price would suggest, but it is still a slight upgrade over the BLON BL-05S.


iBasso IT00 ($60 USD)

Like the Whizzer HE01, the iBasso IT00 comes with nice accessories, and features a mild V shaped tuning. The iBasso IT00 has very bad driver flex though, so that’s one thing to note as it can be a dealbreaker for some. In terms of tonality, the iBasso IT00 has more subbass rumble/quantity but lesser higher treble extension.

In terms of technical performance, the Whizzer HE01 is better, featuring better clarity, details, imaging and instrument separation. Transients are also faster on the Whizzer HE01.


HZSound Heart Mirror ($49 USD)

The HZSound Heart Mirror is a neutralish bright set, and has a more compressed soundstage than the Whizzer HE01. The HZSound Heart Mirror is also more difficult to drive and has a more neutral bass compared to the iBasso IT00. The HZSound Heart Mirror has a thinner note weight too. Accessories wise, they are both very good.

In terms of timbral accuracy, the HZSound Heart Mirror is a tinge better. In terms of technicalities, they are very close.

Though if one does not have an amp, I would suggest to look elsewhere from the HZSound Heart Mirror, as it sounds meh with a low powered source, with a compressed soundstage, thin note weight and lack of dynamics. The Whizzer HE01 on the other hand, sounds good even from lower powered gear.

I would see these 2 sets as sidegrades, both sets have good transients and technicalities. The HZSound Heart Mirror is more suited for those wanting a neutralish technical and analytical tuning, while the Whizzer HE01 is for those that want a more fun V shaped sound. The Whizzer HE01 by virtue of having more bass quantity, may be more suited for bass forward music genres too, but both are good sets to get, depending on your sonic preferences and usual music genres you listen to.



CONCLUSIONS

The Whizzer HE01 features a warm mild V shaped tuning, and is an all rounder single DD set that scores good marks in tonality, timbre and technicalities. Transients are a particular standout on this set. Accessories and haptics are nice and I would say it is one of the standout sub $100 CHIFI single DDs of 2021.

Definitely recommended for those who are wanting to dive deeper into the rabbithole from the sub $30 USD single DD segment!

Killer sound choices with aftermarket tips
Pros: Fun but balanced tuning, flashy looks, comfortable weight and fit, excellent scaling/tweaking potential
Cons: Quality, design, slightly loose mid bass?
I'll keep this short as other reviewers have *gone really in depth. Compared to the Moondrop Aria, the HE01's size and weight is really desirable. My listening tests were done through a Motu M2 interface using a KBear 8 core limpid pure silver cable as well as the original one. My set had only undergone a few minutes of burn in prior to the testing if this is an important consideration for you.

Pros:
Sound is great, punching above its weight. Out of my incomplete tip arsenal (still waiting to get Final E tips and Acoustune tips), only 3 sets are better than the stock tips imo. First of all, for the most balanced sound and killer mids, the Radius Deep Mount tips. Second, the Azla Xelastec tips if you like excess treble air without overdoing it. Last, the Azla Sedna Short tips if you want to transform this into a literal bass canon. All three of these tips do not upset the balance in vocals, keeping it very natural, while attaining a shockingly clean soundstage surpassing that of the original reference tips. The other tips in my collection, including the Spiral Dot (original and ++) and Sedna Original tips fared way worse though, so I commend them for designing/selecting decent regular tips for the price (the Azla and Radius tips are kind of unique and pricey). The flexibility with these tip combinations basically means 3 different sound signatures (all offering quality sound) can be obtained through this single pair of IEMs, if you're willing to go the extra mile. Otherwise, it is also perfectly likeable as is.

Cons:
However, the HE01 does not come without its flaws. The metallic nozzle of my left earpiece had excess hardened glue all around its base, but not enough to affect tip fitting so it's alright I guess. Next point is also about the metal nozzle, which has a large diameter and flare at the end aiming to keep ear tips secure. This is all fine, but the recurve and sharp edge of the flare meant that they overdid it a little. Changing tips is a hassle in most cases, and the sharp metal recurve managed to start shredding the interior of my Azla Sedna Short tips after a few tip swaps during my testing (I discovered this to my horror after seeing strange rubber/plastic shavings sticking out within the nozzle).

I also do not appreciate the plastic extension holding the 2 pin receptors, for they jut out at an angle more extreme than most, causing them to extend forward beyond the ears, reducing support and increasing unnecessary cable strain. This makes them ideal for C shaped connectors- caveat being that such connectors are hard to find in a 2 pin configuration that can fit these due to the receptor region being circular in shape (most C shaped 2 pin connectors are rectangular), which ultimately makes the plastic extension for the 2 pin connection a major design flaw imo.

Apart from these design flaws regarding the nozzle and 2 pin extension, it is a rare IEM that I can thoroughly love and recommend :thumbsup:

*Edit for spelling

PS: After an initial burn in period, the sound seems to have changed significantly, becoming darker. Only the Xelastec and Spiral Dot ++ tips sound nice at this point. Will continue monitoring
Update: Back to normal after some more burn in, refer to original impressions

would you be able to elaborate more the differences between Aria and HE01?
PhoenixSong
PhoenixSong
Yes, but I can make a rough comparison now as my Aria has 200 hours of burn in while the HE01 only has a few minutes. It wouldn't matter for people who don't believe in burn in though

Ah Ok.. I'll be waiting after it burned then.. 😉
