The Latest Product from Simgot

Simgot is a premier manufacturer of audio products with a focus on delivering superior audio fidelity, cutting-edge design, and unparalleled user experiences.

Sputter Deposition Purple-Gold Diaphragm Technology

The heart of the EA1000 lies in its extraordinary SDPGD™ Technology. Developed over three years by Simgot, this diaphragm is a testament to precision and ingenuity. It boasts remarkable characteristics, including high rigidity, exceptional hardness, lightweight construction, and the perfect blend of elasticity required for deep bass. Unlike conventional titanium or beryllium diaphragms, the Purple-Gold Diaphragm undergoes a meticulous process involving multiple layers of transparent, custom-targeted vacuum high-temperature sputtering on a specialized base film. This results in a mesmerizing, mysterious purple-gold hue, achieved through the interference of reflected light from both the base film and the sputtered layers.

2nd Generation Dual-Magnet Dual-Cavity Dynamic Driver

Derived from the flagship EA2000 and further optimized, the second-generation DMDC™ dynamic driver revolutionizes earphone design. Unlike traditional single-magnetic circuitry, DMDC™ dynamic driver offers both inner and outer magnetic circuits, delivering unparalleled magnetic flux. This enhances dynamic range, transient response, and widens the frequency range. EA1000's control over high frequencies is also significantly improved, providing an awe-inspiring, immersive experience.

1DD+1PR Acoustic Architecture

Building upon EA2000's success, the EA1000 utilizes a 10mm Dynamic Driver (DD) paired with Passive Radiator (PR) configuration. This innovative design enhances low-frequency texture and ambient dispersion. The interaction between the Purple-Gold Diaphragm and the airflow in the rear cavity generates subtle vibrations and reflections, fine-tuning the bass and adding a natural ambiance.

Detachable Nozzles

The EA1000 features a threaded, interchangeable nozzle design, offering endless possibilities for sound customization. It comes with three meticulously crafted nozzles: one brass and two stainless steel. These nozzles, each with its unique tuning philosophy and approach, allow users to switch between 3 different tuning styles, expanding the headphone's adaptability and catering to different sonic preferences.

High Purity Silver-Plated OFC Litz Structure Cable

EA1000 comes with a state-of-the-art high purity silver-plated OFC Litz structure cable, which ensures that your audio signal remains untainted. Say goodbye to interference and distortion, and hello to pure, unadulterated sound.

Bought 3 sets already

Exceptional sounds and excellent for vocal. Bought for my family two more sets. I was using it primarily during daily exercise. The only issue was the buds may fell off the cable occasionally .No big deal. Thumbs 👍

Simgot EA1000 - a little gem

Great design and well build. Comfortably fit in small shells. Natural timbre, great resolution, details, bass and vocal texture. Wish it had a bit more base quantity, wider sound stage and a choice of balance cable.

Linsoul sent the wrong product and made me lose money paying for return

The whole experience was a nightmare, Linsoul's RMA is a joke, I still haven't received a refund after returning the product and I don't think I ever will.
If you absolutely need to buy from Linsoul, do it through Amazon because they are compelled to be honest there, don't waste time and money buying directly from Linsoul because if anything goes wrong they will do everything in their power to make sure you pay for their mistake.

Great IEM

If youre looking for a great sounding IEM for this pricerange this is a good choice.
The ea1000 is a good all rounder but its especially great with music that focuses on vocals.
The IEM comes with a tuning set that lets you customize the audio.

Laurent Douvry
An Amazing iem not only for the price

I really like the EA1000.
A very natural but not boring iem, especialy with the 3 nozzles.

Worthy Contender in the <$300 Price Range

Harman 2019 or not, SIMGOT EA1000 Fermat is a set tuned well. Detailed, fun and enjoyable. Fast bass response and natural timbre. Though it can sound slightly too bright for certain songs, it isn't a dealbreaker. Changing the ear tips may help. I haven't changed the nozzles yet but I don't think the tuning would change much.
The iems fit very comfortably in my ears, more so than the EA500. The EA500 is comfortable to wear over time but the EA1000 is even better. They have a similar build but the EA500 is slightly heavier. The Litz cable is of high quality, no matter how it looks and feels. The carry case looks stylish and the magnetic lid is convenient. Overall, an excellent contender among the <$300 iems. Give it a try if it's within your budget.

Very Impressive!

The EA1000 is quite an impressive set, especially at $220. Although it will undoubtedly be bright for some, the EA1000 is, to my ears, the best implementation of Harman 2019. It's incredibly detailed, dynamic, and engaging. And the passive radiator is a fun add. The EA1000 quickly became one of my top 3 releases of 2023. It's right up there with the Softears Studio 4 at more than double the price. If you're a fan of clinical but lively sets, the EA1000 is a must try.
