Weirdly no thread for one of the most youtubed IEMs at the moment. As its highly tunable and moddable with nozzles, filters, mesh, micropore etc, a dedicated thread could be useful to consolidate all the knowledge and impressions.
At launch seemed to be Linsoul exclusive, but is now selling from other stores as well.
Launched Feb 2023 at RRP $79
I own this IEM and I think it is really good. The fact that you can easily tune up the bass with some 3M micropore is just cool, although I dont find it lacking in bass in stock with red filter. My other main IEMs and reference points are Campfire Andromeda 2019, Ikko OH10 and Letshuoer S12 Pro. I don't have much experience with the other newer releases but compared to my IEMs the EA500 has its spot being clear, well-separated, airy and dynamic.
Would be fun to know if the same "4th Generation DLC Composite Diaphragm" from the EA500 is used in other IEMs. Otherwise it likely will be and 2023 looks to be an interesting year for value IEMs.

Technical Details
DRIVERS: 10mm dual-magnetic-circuit & dual-cavity structure dynamic
DIAPHRAGM: Fourth-generation DLC composite diaphragm
IMPEDANCE: 16Ω+15% (@ 1kHz)
SENSITIVITY: 123dB/Vrms (@ 1kHz nozzle with red ring) 124dB/Vrms (@ 1kHz nozzle with black ring)
FREQUENCY RESPONSE RANGE: 10Hz-50KHz
EFFECTIVE FREQUENCY RESPONSE: 20Hz-20kHz
CABLE: High-purity silver-plated OFC wire
CONNECTOR: 0.78mm 2-pin
Product Features
The EA500 adopts a 10mm dual-magnetic-circuit and dual-cavity driver. Different from the two single magnetic circuit forms of "internal magnetic" or "external magnetic" commonly used in dynamic headphones, the dual-magnetic-circuit system of EA500 provides both internal and external magnetic circuits.
Combined with the N52 magnet, this driver presents a powerful magnetic field and amazing performance. The dynamic range and transient capability have been greatly improved, providing a wider bandwidth range and lower distortion, which gives the EA500 a stunning dynamic and sense of presence.
4th Generation DLC Composite Diaphragm
The DLC composite diaphragm of EA500 incorporates 3 kinds of different materials, which are used to build different parts. DLC is characterized by strong rigidity, high damping, and light-weight, and is used as a dome that determines the characteristics of treble.
The edge, which affects the mid and bass, is built with elastic composite material. The whole diaphragm has undergone multiple pattern design and material content ratio tests to achieve surging and natural bass, high resolution and high-density mid, and smooth treble extension.
Detachable Nozzle Design, Two Target Curves
By quickly disassembling and installing the nozzles of different tuning cloth systems, users can change different tuning styles. When the filter is blocked after a long time wearing, users can replace the filter themselves, which can extend the service life of the product and increase the scope of adaptation.
Nozzle 1 (red silicone ring)
H brand-2016 Curve is a very universal trend-oriented tuning style. It is also the basic target curve widely used by different brands of audio manufacturers in the industry (on this basis, each brand has a slight derivation). The three frequencies are highly balanced, the positioning is accurate, the sound field is restored accurately, and the sound is plumb. It has less sibilance on the treble, adapts well to different music genres, even to poor recording. This tuning style can be sorted as "jack of all trades".
Nozzle 2 (black silicone ring)
SIMGOT-Classic's target curve runs through the tuning ideas of EN1000 and EA2000. Through appropriate gain of the treble and slight forward shift of the first peak, on the basis of ensuring accurate positioning and clear image, the three-frequency keep balanced, making the instrument more beautiful, the separation clearer, and the female vocal more addictive. There may be slight sibilance in the treble, but the resolution is higher and more details can be presented. It is a little bit weak to adapt to poor recording source.It belongs to tuning style of "female vocal addictive”, or " instrument type”.SIMGOT will continue to develop the nozzle of EA500 to bring more tuning styles under different target curves.
All Metal Cavity With Mirror Plating Process
The headphone cavity is processed through high-density alloy metal melting & casting and CNC fine engraving. The body is sturdy and durable. The inner surface is subtle uneven, which can effectively suppress standing wave and provide a clear sound floor.Complemented by mirror plating technology, the earphone body is elegant as an art piece.
Stable And Reliable 2-Pin Detachable Design
High quality silver-plated OFC cableThe EA500 comes with a high-quality 0.78mm 2 pin detachable silver-plated OFC cable. This cable effectively improves the separation and transparency, making the sound floor clearer, the vocal and instrument more beautiful. The detachable design also leaves space for cable upgrade and brings more fun. The 2-pin is durable with long service life.
