The ORIVETI OD100 is marketed as a highly portable and affordable small form factor IEM that does not compromise on sound quality. The OD100 employs what ORIVETI calls a tiny ergonomic IEM design which I call bullet style.
OD100 comes with a single 9.2mm dynamic driver that employs a Diamond-like carbon diaphragm backed by a high-density voice coil. The 9.2mm driver produces a frequency response of 20Hz to 20kHz, an impedance of 16Ω alongside a 0.08% distortion rating.
The face plate has a subtle swirl pattern but the rest of the body is just polished metal. The output nozzle does show a small point of interest in that there is a mesh grill but there is an additional phase plug in front of the mesh.
The stock cable is a 4-core silver cable with metal connectors. It handles well in the hand and it’s on the softer side which is always welcome. The cable uses an ORIVETI-branded gold-plated 3.5mm plug and a matching split with a metal chin slider with matching male 0.78mm two-pin connectors at the top ends.
I would like to thank ORIVETI for providing me with the review sample of OD100.
This is a V-shaped sound signature, with an emphasis on the bass and treble regions, and a recessed midrange. The sound is energetic, dynamic, and fun, but it may not be suitable for those who prefer a more balanced or neutral presentation.
The bass of the ORIVETI OD100 is powerful, deep, and punchy, thanks to the 9.2mm dynamic driver. It has a good impact and rumble, especially in the sub-bass region, but it can also bleed into the midrange and cause some muddiness and congestion.
It is still tight and well-controlled and is the best I’ve heard in the price range. The bass quantity is also some of the best I’ve heard but may be too much for some listeners, especially those who are sensitive to bass or who listen to genres that do not require a lot of bass.
However, I quite enjoyed the unit’s bass response. I found myself gravitating to the Shanling Sono whenever I was in the mood to listen to hip-hop and pop music. It can deliver thumping beats, and deep bass hits, giving the music a slight warmth.
The sub-bass playback is a standout, being able to hit low notes without coming off as too overwhelming or muddy.
The OD100 is neither forward, nor recessed. It presents vocals and midrange in a “middle” ground physical area for the listener. Interestingly, the tonality of the entire mid-spectrum is satisfyingly dense and bulky, feeling hefty and solid.
Now, I do not want to get stuck on pricing stigma, but generally, very cheap products don’t sound that nice and thick. They generally sound frail, thin, washed out, or lacking a nice, tangible substance factor.
Such is not the case with the OD100. It portrays a solid framework for the bass and midrange, although that changes when you get to the upper mids area and into the treble, which tends to sound a bit strangely cut off from the heft of the lower portions of the spectrum.
That is not a terrible quality, it is just that the upper mids start to taper off a bit and lose the nice density factor, appearing to feel lighter and more aired out, brighter.
The fidelity factor is audibly on par with the SIMGOT EA500, which sells for closer to $79. So yes, the OD100 punches higher than its price tag and can roll with the just under $100 crowd.
The top side of this IEM is bright, vivid, and plentiful. Oddly, it is much brighter than the lower mids and there is a solid cut-off point in the upper mids that blends into the treble area, usually.
In this case, it’s more like a knife slicing butter and then suddenly, the treble. It’s plenty clean and not at all a lower fidelity. What is there is nice, enjoyable, and vivid at times.
Quantity factor aside, the fidelity factor and tone score high on the price-to-performance ratio. I consider the OD100 to house on par quality with the SIMGOT.
There is no sibilant and you can confidently raise the volume never to encounter any harshness. The highs/super-highs difference didn’t strike me, but if you prefer highs over lows, you’ll hear a real difference/improvement.
The plentiful amount of air in the treble region of this model makes the experience feel lighter, more aired out, and spacious, but that comes at the cost of some treble brightness.
I would rate this model’s imaging and sound staging properties as shocking good when the price is in mind. It isn’t going to win awards, but as a first-time audiophile steppingstone for gifts, this is the best IEM out there that I can think of that is a great allrounder and that can be boosted with bass, dialed down a bit on treble, but also that offers a nice and spacious feel.
Gateway models like this, so to speak, are usually best-buy items on the market. In my opinion, the OD100 is one of the better cheap models out there for imaging needs.
If I had to gripe, the depth of field feels a little flat in comparison to the left and right sizing of the image. Staging left and right is spacious and open feeling. Stage-depth is just good, but that is still comparable to the IEMs I’ve mentioned already which are more than double the price.
For anyone in need of “big sound” on the go, with something that could be driven by any source, the OD100 appears to be the solution. They’ll excel in Techno-music, rock, metal, or even deep-house, but classical users might be a little more skeptical – even if they could work, with a good source. These are great all-rounder, ones that can be used daily and still surprise you.
