DISCLAIMER
I would like to thank Simgot for providing this review unit. The EA500 can be obtained here: https://www.linsoul.com/products/simgot-ea500 (no affliate links).
SPECIFICATIONS
Driver configuration: 10mm dual-magnetic-circuit and dual-cavity driver, utilizing 4th Generation DLC Composite Diaphragm
Frequency response: 20 Hz – 200000 Hz
Impedance: 16 Ohms
Sensitivity: 123dB/Vrms (@1kHz with red nozzle), 124dB/Vrms (@1kHz with black nozzle)
Cable: 2-pin, 0.78 mm, silver-plated OFC wire
Plug: 3.5 mm
Tested at $79 USD
ACCESSORIES
Other than the IEM, these are included:
- 3 pairs of silicone ear tips (S, M, L)
- Cable
- Carrying case
- 2 pairs of tuning nozzles
- 7 pairs of red marker bands for tuning nozzle
- 7 pairs of black marker bands for tuning nozzle
The accessories are more than decent for a budget pair of IEMs, perhaps other than a dearth of eartip choices. There are no foam tips included, and only one type of silicone tips are packaged.
Said silicone tips are thankfully quite comfortable, though they make the sound signature a tinge shouty. If you have aftermarket eartips, please try tip-rolling, as this may improve the sonics to your preference.
The stock cable is made from silver-plated OFC. It is one of the better stock cables I've encountered in a budget pair, being quite supple and tangle-free. I appreciate that it has zero microphonics, and there's a chin cinch to give added stability. 2-pin cables are always my preference, as MMCX connectors may become loose with frequent cable changes, YMMV.
The provided semi-rigid ovoid case is made of PVC and is quite generic looking, but is very spacious to hold multiple contents. The innards have a soft covering, with webbing. There are 2 pairs of tuning nozzles, which we will go into further detail below, and there are additional coloured bands provided as spares.
The rest of this review was done with the stock cable and stock tips. No aftermarket accessories were used, so as not to add any confounders to the sound.
BUILD/COMFORT
The EA500 housings are produced via high-density alloy metal melting/casting and CNC engraving. Indeed, the shells are really alluring and refined, featuring a mirror-like finish. Do take care of these babies, as the mirror-like finish can be easily marred by fingerprints, or worst still, scratches!
Comfort is top-notch. The housings are ergonomic, with no awkward protrusions. I've used them for marathon listening sessions with no issues. I encountered no driver flex on the EA500, but this is partially dependent on ear anatomy and/or type of eartips used, so YMMV.
ISOLATION
Like most DD IEMs, the EA500 is vented, and isolation is below average, though it should still be usable outside.
DRIVABILITY
I tested the EA500 with:
- Khadas Tone Board -> Schiit Asgard 3 amp
- Khadas Tone Board -> Topping L30 amp
- Creative Sound Blaster X5
- Hiby R3 Pro Saber 2022 DAP
- Shanling M0 Pro DAP
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Questyle M15 DAC/AMP dongle
- Apple dongle
- E1DA DAC/AMP dongle
- Colorfly CDA M1 DAC/AMP dongle
- Truthear SHIO DAC/AMP dongle
- Tempotec Sonata HD Pro dongle (BHD firmware)
- Smartphone
The EA500 is very easy to drive, though this set scales with juice, in bass tightness, soundstage and dynamics. Interestingly, the red nozzles are more difficult to drive than the black nozzles (probably more damping material), which we will talk about below.
SOUND & TECHNICALITIES
The EA500's selling point, is its versatility in view of the two tuning nozzles providing a subtly different flavour. On the black nozzle, the EA500 has a neutral bright lilt. Whereas there's a warmer Harmanish tone on the red one.
Graphs of the EA500, using an IEC711 compliant coupler. 8kHz area is a coupler artefact peak.
I'm glad to report that other aftermarket tuning nozzles (eg from Moondrop Kato and Hidzis MS5) are compatible with the EA500, so this increases permutations exponentially - please tinker to your heart's content! For the purpose of this review, we will be keeping to just the stock nozzles.
Back on point, the tuning nozzles really work, and are not gimmicks (cough cough, looking at you Moondrop Kato). Essentially, the black nozzles give a neutral bright analytical signature, with superior technicalities, albeit with a thinner note weight. However, the black nozzles can be somewhat fatiguing/shouty and sibilant in the treble.
In the big scheme of things, with the black nozzles installed, the EA500 is top-notch in technicalities, for a sub-$100 USD single DD set, with just the soundstage being on the more intimate side. Imaging is quite good, with stellar instrument separation, clarity, micro-detailing and transients noted.
The red nozzles on the other hand, provide a balanced, warmer, and more laid back soundscape, with minimal fatigue, though at the expense of bass tightness and technical chops. The technicalities with the red nozzles on board hits just above average when compared against other single DD peers. Note weight is thicker with these red nozzles.
Timbre on both nozzles is quite natural sounding, especially for vocals and acoustic instruments.
Bass on the EA500 is just a tinge north of neutral, and is mid-bass focused, with just slight mid-bass rumble/extension. The bass is lesser in quantity on the black nozzle, but it is tighter and cleaner on the this nozzle, with a fast and agile bass line heard with minimal mid-bass bleed. Once the red nozzle comes into play, the bass is slower, with some smearing, loss of texturing and mild mid-bass bleed noted on complex bass tracks.
The lower midrange is a tinge depressed. Upper mids are boosted on both nozzles - this region can be quite shouty, especially at higher volumes (Fletcher Munson curve) with the stock tips. Playing the EA500 at low to moderate volumes, or perhaps tip-rolling with other eartips may help mitigate this region thankfully.
The lower treble is boosted on both nozzle settings, more so on the black nozzle. There's quite decent treble extension and air on the black nozzle, with the red nozzle more conservative in the upper frequencies. The black nozzle does unfortunately result in a bit of splashiness with cymbals and high-hats, and sibilance is displayed. The red nozzles are sibilant-free and quite safe for treble sensitive folk.
Thus, if one desires something for critical listening and to analyze music, or if you are a treble-head, then the black nozzle would be the perfect option. For a more chill pleasant tuning (with still acceptable technicalities), with a thicker note weight and a more "balanced" profile, the red nozzles will be the go-to.
COMPARISONS
The EA500 will be compared against some other well-known DDs at the sub $100 region. Pure BA, planars and hybrids are left out, as the different transducers have their own pros and cons. Comparisons are done with the black tuning nozzles installed on the EA500.
TRI Star River
The Star River is a dual DD with tuning switches. On paper, there are purportedly 4 tuning options, but on independent measurements, there are only 2 tunings, so it is quite scammish.
Graphs of the TRI Star River, using an IEC711 compliant coupler. 8kHz area is a coupler artefact peak.
The QC on the Star River is questionable - on one of the housings on my set, the switch is almost stuck, and needs great force to be toggled - it probably won't survive a few more activations.
Dodgy QC and switcheroo shenanigans aside, the Star River features old school shouty V shaped tunings, with fatiguing pinna gain. Timbre is artificial and technicalities are below par.
The Star River is a disaster all round, and the Simgot EA500 is the undisputed gold standard for a tunable DD IEM at this price bracket. The Star River seems to be forgotten after the initial hype, but I'd stick my neck out and say the EA500 will arguably still be in the conversation for best budget DD IEM come end of this year.
HZSound Heart Mirror (original)
The Heart Mirror (original) is a neutral bright IEM, and also has a nice mirror-like finish. The Heart Mirror is notably more difficult to drive.
The Heart Mirror is more sterile sounding, and is more fatiguing/sibilant in the treble region, with less bass. In technicalities, the Heart Mirror have the upper hand, with better imaging, instrument separation, clarity and micro-detailing, though soundstage is better on the EA500.
Timbre is more organic on the EA500, with the Heart Mirror having a nasal whiff. The Heart Mirror does not have tuning options unlike the EA500, so versatility goes to the latter.
DUNU KIMA
The KIMA is a very safely tuned Harmanish single DD.
The KIMA has a wider selection of tips in the packaging, and also has quite good timbre, though the EA500 kills the KIMA in technicalities (soundstage, imaging, instrument separation and micro-details), and it isn't close.
The KIMA cannot be tuned.
At this price bracket, the KIMA is kind of a jack of all trades, master of none IEM, and is nothing too special.
Tripowin Olina SE
The Olina SE is Harmanish with a slightly more artificial timbre.
Technicalities wise, it is a wash, and these 2 budget kings are very close, the Olina SE has a slightly bigger soundstage and a tinge better imaging, though micro-detailing and instrument separation are a hair better on the EA500.
The EA500 has tuning options, unlike the Olina SE, and the Olina/Olina SE seems to have complaints of the nozzle mesh trapping moisture and causing issues, which isn't the case with the better build on the EA500.
Moondrop Aria 2021
The Aria 2021 is bassier (boomier) and less bright. The Aria 2021 lags behind in technicalities, with markedly inferior imaging, micro-details, instrument separation and clarity.
The Aria 2021 also has a metallic timbre, and it is quite outclassed by some modern day single DDs, not to mention the EA500. The Aria 2021 is also not tunable.
DUNU Titan S
The Titan S is a neutral bright IEM. It is a bit uncomfortable due to long nozzles.
The Titan S has a more rolled off sub-bass, and is a bit more biting in the lower treble. In technicalities, both pairs are quite technical at the sub-$100 range for a single DD, though the EA500 shades it a bit, and on A/B testing, the EA500 wins slightly in soundstage, micro-detailing and instrument separation.
The Titan S is not tunable, so the EA500 is a more versatile set.
Toneking Ninetails
Last but not least, we pit the EA500 against another tunable single DD cult-classic in the Toneking Ninetails.
Graphs of the Toneking Ninetails, using an IEC711 compliant coupler. 8kHz area is a coupler artefact peak.
The Ninetails are named after an ancient Fox Spirit which can shapeshift. Indeed, the namesake is quite on-point, as this IEM has front and rear tuning nozzles, giving a total of 9 permutations for tuning. Hence, it can be a basshead headache inducing monster, to something neutral, to even a treblehead's dream.
So in terms of versatility, the Ninetails is better, though it has a more uncomfortable fit due to a weird gourd shaped design. Timbre is very organic, in keeping with its single DD roots, but in technical chops, the EA500 wins hands down, with better bass tightness, faster transients, and superior imaging, instrument separation and micro-detailing.
CONCLUSIONS
The EA500 is one of the stand-out releases of this year so far. It easily punches above its weight, and excellently melds the 3 Ts of timbre, tonality and technicalities into a very pretty chassis. In addition, the EA500 is extremely easy to drive.
Unlike some other tunable IEMs that are gimmicks, the EA500's tuning nozzles work, and it can veer from a neutral bright technical animal to a more chill Harmanish smooth set, so the versatility is another feather in its cap. One is essentially obtaining 2 IEMs with the EA500 in view of this, so the value proposition is nothing to be sniffed at!
There are some minor nitpicks, such as a dearth of eartip options, and there are slight compromises in both tuning nozzles (the black may be slightly fatiguing/sibilant, and the red may not be the tightest in the bass or most technical), in addition to the EA500 not suiting bassheads, and having some shoutiness.
I would say these are small trade-offs in the big scheme of things, compared to the overwhelming benefits the EA500 brings to the budget CHIFI table. Indeed, I do think the EA500 will be a benchmark among budget single DDs for 2023, and will be the standard that new releases should aspire to meet, instead of the weekly hackneyed sidegrade spam that are forgotten after a couple of weeks.
The EA500 has my stamp of approval, and is definitely a pair to consider if you are intending to join the budget CHIFI bandwagon.
