ORIVETI OD100 REVIEW: The Little IEM that could.
Pros: Lightweight and comfortable.
Solid strong durable metal construction
Engaging sound
Good bass impact and excellent vocal timbre
Treble is detailed and balanced.
Imaging and soundstage are very good.
Cons: Sub bass roll off so not for bass heads.
Upper midrange can be a little hot on a minority of recordings.
Overall refinement and technical ability just below class leaders at this price point.


Oriveti is a Chinese audio company, originating in 2015 and based in Hong Kong.
TheOD100 IEM has been provided free of charge to the Audio Reviews Downunder Australian tour group for a honest and considered review. We thank Oriveti for this opportunity.

TheOriveti OD100 is the baby of the company’s range with a price of approx. $70 usd. It features a steel milled body that is small and compact for ease of use on the go and a diamond-like coated single dynamic driver. It is provided with a 4-core silver plated cable anda selection of eight ear tips and includes a solid and roomy carry case.
Because of their small size they are light weight and can be used with cable over ear or hanging down bullet style. The shells have vent holes, so no driver flex was experienced and isolation from outside noise is just average.

Firstly the OD100 is being auditioned with FLAC tracks from my Hiby R3 SaberDAP using TRN T tips (Vocal and soundstage enhanced) and today, a NiceCKH BlackCat Zinc Copper Alloy Oil Soaked Cable ( bass enhancement ).

I think I have discovered a synergy between my DAP and these IEMs because instantly the sound I am hearing is impressive to say the least. Listening to “Kingdom of rain” by The The. I am in the middle of a thunderstorm, with rumbling thunder and rain on foliage and the acoustic guitar cuts in with complete fidelity. Electric guitars howl left and right then the bass guitar and vocals enter. The vocals are quite forward and the midbass has excellent punch and impact. The upper midrange and lower treble are emphasized giving a vibrant and energetic sound. Overall, the sound has a mild warmth which makes vocals engaging and conveys emotions well. The bass goes deep when asked but generally has a lighter more neutral feel when compared to more sub bass centric IEMs.

Left and right sound elements are spaced nice and wide, and depth and height are quite adequate. The audio is nice and airy and uncongested. Imaging is very good. Placement of instruments and backing vocals is easy to ascertain.

Can I say that I really enjoy the vocals on this set. Never has Taylor Swift quite had this ability to melt my heart! Male vocals too! Tone is organic and natural and presented nice and forward and sucks you in.


So where does the OD100 sit in the sub $100 market, an area that is hotly contested.

Well, it’s not a basshead IEM and its not a technical detail monster.

But it is an extremely accomplished single dynamic driver design that gives a balanced, mildly warm, energetic, and fun sound. It’s small, comfortable, durable and a very engaging listen. I was impressed with the Oriveti OD100.

Oriveti is a Chinese earphones company founded in 2015.
I've review and adore their flagship balanced basshead IEM call OH700VB.
Today I will review their entry level IEM call OD100.
Priced only 70$, the OD100 is a single dynamic driver IEM promising high sound value and using a 9.2mm DLC (diamond-like-coated) dynamic driver.
Let see in this review if this is an IEM that can truely compete in most unforgiving price range of them all: sub-100$ hypertrophy chifi IEMs market.



The construction of OD100 is all made of high grade CNC milled metal which is polished and glossy, very smooth in hands, small in size and seems tremendously sturdy for long time durability.
The 2pin connector feel sturdy but their are slightly recessed and has oval shape which will create mini gap with some cable.
The Nozzle is short and since the desgin is thinked for around hear, i find the fit a bit problematic and prompt of falling from my ears.


The included cable is a 4 cores silver plated cable of good quality. It's well built and feel sturdy, it's above average cable for a 70$ IEM.

Rest of accessories are minimal, but again of good quality. The carrying case is very good, it's solid and thick and has enough space for 2 cables and some extra IEMs. This is a very welcome accessory. Other one are 8 pairs of eartips including 3 pairs of memory foams. Again, very good.




The tonality of OD100 can be summarized as balanced V shape to bright neutral with slight mid bass boost and a main focus on treble, it’s near analytical and highly resolved with boosted presence of instruments that are loud. It isn’t suggested for those that are sensitive to lower treble and female vocal loudness since this is quite forward, upper treble too is upfront and quite impressive in extension past 10khz, which is something very rare in the sub-100$ price range.

The bass isn’t for basshead at all, it has a warmish punch to it that feels mellow, not hard hitting nor very high. The bass line presence is more boosted than their body which is a bit thin but it’s well textured and their this much needed attack bite for double bass or electric bass that add a sense of energy to the bassist playing while not offering proper rumble or dense resonance release of infra bass.
This makes bass line definition brighter than kick drum which is more about physical presence, about gentle ‘’oomph’’ hitting without the best separation with lower mids.
Due to the whole treble being more upfront of bass and mids, the drum dynamic is understated and a bit distant while its percussions feel detached and more upfront as if we have 2 different drummers in different positions of the stage.
When I say mid bass is boosted, it’s in the sub bass lead too, which means we can have a good slam especially with modern pop music that uses digital instruments, the issue is mostly for acoustic music. So, this is a niche bass, not a versatile and natural one.Don’t expect hard clean thump nor a perfect definition.
All in all, this isn’t bad bass per se, but sub bass is rolled off and lacks natural release and the dynamic feel overly damped in attack.

The mid range is bright and transparent, open sounding but leaner in dynamic than the rest of the spectrum, apart from upper mids which are quite boosted and favor female vocals in terms of immediacy and loudness. This can cause fatigue and some sibilance too, depending on source matching, this is problematic with neutral bright source like Xduoo X20 while with a warm dongle like Penon Tail the sibilance isn’t invasive but vocals are still very upfront.
The piano on the other hand feels a bit recessed and thin and light in note weight, yet its resolution is good, tone wise it lacks a bit of low harmonic fullness and sound dry to crisp depending on pitch range.
For saxophone, we have the same treatment as female vocalists. Due to the lack of low harmonic, it can feel a bit over centered and compressed, as well, it can be borderline shouty when the saxophonist goes loud and high pitch.
Timbre wise, it’s not the most natural and tends to lack warmth to glue together texture details and air vibrancy.
All in all, I'm not a fan of this mid range which is the main qualm for me with this IEM. I've heard way worse but upper mids emphasis is too much and sense of fullness isn’t there. Male vocalists are more favored in presence brightness and can feel too hot at times, we miss the baritone lush deep tone as well.

Now for the treble it’s both the highlight and ‘’sword of Damocles’’ of OD100, in the sense it’s what impress the most in term of technical prowess and high resolution achievement, but it’s the type of highs that can go unbalanced when it come to percussions, putting it too forwards to the point of distracting the listener from main instrument.
For example, in a jazz trio i'll be able to track double bass line and percussions more easily than kick drum and piano, it’s its saxo, it will feel a bit better balanced in loudness and dynamic, but the extremely snappy, sparkly and speedy percussions will still force my focus to follow their rhythm section to the detriment of full harmonious composition.
Nonetheless, the wow effect is there and the treble head will be impressive for sure. The highs are airy, it has a lot of shimmer, it’s cleanest part of the spectrum and has a sharp attack with boosted brilliance.
When it comes to instruments like violin, presence is notably more favored than harmonic density, it’s edgy in attack which can deal with fast playing yet it’s not a lush tone and can feel a bit grainy.
For acoustic guitar, harps or Kora instrument of Ballaké Sissoko, this kind of treble is magnifying crispness of instrument presence, permit sharp attack lead with an airy sparkly release but it can feel a bit thin and overly metallic too, depending of your musical appreciation this can go from wow to What appreciation.
This means that OD100 is generous in micro details too, thus the near analytical musicality I perceive.
All in all, this isn't the best treble in terms of balance but in terms of performance It's good for it's price.

The Soundstage isn’t bad but nothing really impressive, it’s deeper and taller than wider so it can feel a bit in your head.

The Imaging is quite good for the price, but not very realistic so it’s not suggested for monitoring purposes when it comes to mixing but for stage musicians like female vocalist, saxophonist or classical guitarist it can be a good entry level choice.




The LM is crisper, more transparent and open sounding as well as leaning more to smooth U shape signature, which make the OD100 sound brighter balanced V shape.

LM bass offer wider slam with more sub bass resonance and extension, it’s more mellow in mid bass punch which is warmer and more rounded with OD100. Bass separation is better layered with LM, bass lines are more textured and less ‘’one toned’’.

Mids are more recessed and less crisp with the OD100, female vocals are more upfront and prompt to shouting and sibilance, their presence is less open and transparent, texture grain is more boosted with OD100. LM mids are a bit thinner and colder.

Treble is notably superior with LM both in micro details retrieval and attack control, which is more snappy, speedy. It extended further so it’s more sparkly and airy. OD100 is more edgy and crunchy in attack, treble is brighter but dryer and rolls off faster. It gets congested faster too.

Soundstage is notably wider and deeper with LM.

Imaging is from another league: more accurate and clean, positioning is sharper and layering more transparent.

All in all, Simgot EA500 is from another league in terms of technical performance and offers a more cohesive and balanced musicality too, which extends further both in bass and treble.

VS Whizzer HE01

HE01 is basically a warmer-darker V shape version of OD100, with more open and natural musicality.

Bass punch is similar but has more sub bass extension and release which is thicker and less compressed, more vibrant and wider in headroom too, thus the slightly warmer tonality.

Then mids are notably smoother yet vocal presence opens up more, embraces the listener with more grandeur, female vocals are less aggressive and shouty and has lusher thicker timbre. Note weight is greater too with HE01 as well as timbre is ultimately more pleasant and less boosted in presence brightness.

Treble is less edgy, less crisp and clean with the HE01, definition of percussion feels more hazy and violin lacks proper attack edge, so overall highs are darker and more colored, sound info are greater with OD100.

Soundstage is wider and taller with HE01, while slightly deeper with OD100.

Imaging of both these IEM is average, so on par here.

Overall performance is similar here but the tonality is better balanced, more musical and natural with the HE01. OD100 sounds a bit more technical and is less warm and bassy-rumbly than HE01.


Coming from Oriverti OH700VB, listening to OD100 is quite a shift in terms of musicality which is brighter and less lush and bassy.

Here I'm not talking about the technical performance of 8x pricier OH700VB but the tonal balance which is notably smoother and even if more bass, it feels more mid centric too, and for me both bass and mids are the Achilles heel of OD100.

It doesn't trigger fun even if slightly V shape, nor impress with details retrieval even if pumped up in brightness.

Those OD100 are certainly not for upper mids sensitive listeners which will find high pitch instrument and vocal release too aggressive, then it might be a good choice for treble head but the quality isn’t really there since it’s a bit splashy.

While not plain bad, OD100 is an IEM that struggle to compete in extremely prolific sub-100$ price range, so for me it’s:

Half recommended!

OD100 7.jpeg

  • Driver configuration: 9.2mm DLC dynamic driver
  • Impedance: 16 Ω
  • Frequency response: 20 Hz - 20 kHz
  • Sensitivity: 105 dB/mW
  • Cable: 2-pin, 0.78 mm cable; 3.5 mm termination

Other than the IEM, these are included:
- 3 pairs of wide-bore silicone eartips (S/M/L)
- 3 pairs of narrow-bore silicone eartips (S/M/L)
- 3 pairs of foam eartips (S/M/L)
- Cable
- Carrying case

For a sub-$100 USD set, the accessories are pretty premium, can't complain much about this aspect.

OD100 4.jpeg

3 variants of tips are included.

Firstly, we have the foam tips, which increase isolation, though they may tame treble sparkle. We next have 2 types of silicone tips - the narrow-bore ones boost bass though with some compression of soundstage; the wide-bore ones increase treble and air.

Do tip-roll to see what suits your preferences.

OD100 1.jpeg

There's no info on the stock cable material, but this cable is pretty well-braided with minimal tangling. Microphonics are also negligible, and there's a chin cinch for added grip. I appreciate that it comes in a 2-pin termination, which is generally less prone to failure than MMCX.

OD100 3.jpeg

Lastly, we have an elegant semi-rigid ovoid carrying case. It is quite resistant to compression, with a velvety interior to cushion the contents. There is webbing internally to to store some accessories too.

The rest of this review was done with the stock cable and stock narrow-bore silicone tips. No aftermarket accessories were used, so as not to add any confounders to the sound.


OD100 6.jpeg

The OD100 is fashioned from CNC-milled metal, and comes in a bullet-shaped design analogous to the Tin T2 series. It is literally build like a tank, and is extremely solid.

Ergonomics are meticulously designed, with no awkward protrusions to poke the ears, coupled with a light chassis. Additionally, this IEM can be worn cable-down or over-ears, which increases fit permutations.

OD100 10.jpeg

Isolation is bang average, as a result of venting, though thankfully, I did not find any driver flex (which is once again a sign of a well-designed acoustic chamber).


I tested the OD100 with the following sources:
- Apple dongle
- Cayin RU7
- Fiio K11 DAC/amp
- Fiio KA13 dongle
- Hiby R3 Pro Saber 2022 DAP
- Khadas Tone Board -> Schiit Asgard 3 amp
- Questyle M15 DAC/AMP dongle
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Sony Walkman NW WM1A DAP (Walkman One WM1Z Plus v2 Mod)
- Smartphone

This IEM is easily driven from weak sources, though it may scale with amplification (in terms of bass tightness and dynamics).


Oriveti OD100.jpg

Graph of the Oriveti OD100 via IEC711 coupler. 8 kHz is a coupler peak.

The OD100 can be described tonally as having a "fun-sounding" bright U-shaped profile.

The mid-bass is the predominant frequency band amongst the bass, with a visceral thump heard on bass heavy tracks. There is just a tinge of sub-bass extension, and it isn't the most rumbly set. Bass is however, clean and relatively fast, with just a hair of mid-bass bleed. Sadly, texturing is average - on very complex bass tracks, the OD100 may come across as one-noted on occasion.

The lower midrange is a tinge recessed, though not overly so. This region is quite transparent without bass encroachment. Unfortunately, the upper mids are an area of contention, with a 14 dB ear gain. As such, vocals may sound slightly shouty, especially at louder volumes (Fletcher Munson curve). This area can be mitigated somewhat with source and eartip pairing, in addition to perhaps using the OD100 at lower volumes.

The lower treble continues on from the augmented upper mids, peaking at 5 kHz. This area is quite clear with decent resolution, though with some smattering of sibilance. Treble extension and sparkle is quite moderate, with high hats and cymbals not overly splashy.

In keeping with its single DD roots, timbre is quite natural for acoustic instruments, though vocals are a bit nasal due to the boosted upper mids.

Technically, the OD100 is probably above average when compared against other sub-$100 USD single DDs. Soundstage is above average in all 3 dimensions, furnishing a spacious soundscape. Instrument separation is quite well rendered, with adequate micro-detailing. Imaging is a tinge fuzzy though, and is not exactly pinpoint.


Comparisons were made with other sub-$100 USD single DDs. Pure BA, hybrids and planars were left out of the comparisons as the different driver types have their pros and cons.

OD100 9.jpeg

Simgot EA500

The EA500 has 2 tuning nozzles to provide more versatility - it can be tuned between a neutral bright lilt on the black nozzle, or a warmer Harmanish tone on the red one.

The EA500 has a more natural timbre, and has improved soundstage, imaging and micro-detailing. It is however, brighter than the OD100 in the treble, and the EA500 may display sibilance and fatigue for longer sessions.

Moondrop Aria 2

The Aria 2 follows the virtual diffuse sound field (VDSF) signature - which is essentially Moondrop's in-house variant of the Harman curve.

The Aria 2 is not as bassy, with a less pronounced upper midrange. The Aria 2 has a smaller soundstage, and a hair less precise imaging, with similar instrument separation.


The Kima Classic is a V-shaped IEM, with more bass than the OD100. It isn't as extended in the treble as the OD100 however.

The Kima Classic has a less natural timbre. In technicalities, it fares worse than the OD100, with inferior instrument separation, imaging and soundstage.


OD100 5.jpeg

The Oriveti OD100 is a decent entrant to the cut-throat sub-$100 single DD ocean. It imparts a "fun-sounding" signature for head-bopping listening sessions. Additionally, this set brings excellent accessories, solid build and comfortable ergonomics to the table, and is also easily driven.

Timbre is quite organic, with above average technicalities and a spacious and transparent soundscape. The OD100 also scores a bonus point in the area of fit - it can be worn cable-down or over-ears, which makes fitting a breeze!

There are some areas for improvement though. Firstly, we have an overly-zealous 14 dB ear gain, which can add to some shoutiness. Bassheads may bemoan the lack of texturing and sub-bass roll-off, and imaging is not pinpoint per se. Some sibilance is present, though there are worse offenders for sibilance when other rival single DDs are compared.

In the big scheme of things, the OD100 would probably be considered as an average budget single DD, and it does more things right than wrong. It is suited as a daily beater set, or perhaps as a gift or introductory pair for folks new to the IEM hobby.
