Here is my unfiltered comparison of the Oriveti OD200 and Simgot EA1000
EA1000 is about details and precision. It's lively, agile and cleaner and transparent. OD200 has a slightly different approach. It's too has the details and precision in it's mind but it's a bit more smoother and less on the face. It has less energetic finishing region and wants to balance things better with a fun yet nicely accurate presentation that isn't fatiguing after some hours.
Let's start with the cable. EA1000 has an inferior cable by a big margin. It's stiff, has a bit of memory too. OD200 has a much better cable that behaves better. Has modularity and better comfort.
If we start with bass OD200 is a bit more punchy with a bigger area of impact and slightly more rumble. Subs are good, mid bass is more prominent with fuller meatier notes but what I don't like is the lack of proper definition. Notes aren't as well separated as I wanted them to be. It's decent, gives a softer landing to most bass notes but that robs it off of details and technicalities. Decay is slightly slower and dynamics aren't great sadly.
EA1000 has a bit more sub bass extension and has better layered delivery and definition of individual notes. It's definitely more technically capable. Notes are tighter but still has good punch and slam. Has a bit faster decay and better dynamics.
Mids on OD200 are very good. Very good vocals. No flaws that I find. It's slightly W shaped but that's fine. Male vocals are grunty while female vocals are petite and accurately tall and energetic. There is no issues of comfort. Instruments are lively and engaging with right amount of finihsing energy and resolution. They aren't very tall or the cleanest but have good definition and clarity. Upper mid is energetic bus nothing to worry about.
EA1000 is slightly different with taller, a bit more energetic approach. Vocals are slightly more textured but a hair less throaty with slightly better resolution. Instruments are a bit more transparent and cleaner. No upper mid devils to worry about.
Highs of the OD200 are similarly energetic and detailed but notes aren't well separated at their bases. Good layering and separation with decent amount of air.
EA1000 is more clean and clear with better definition and air at the floor. Instruments have better separation are their origin points. Has slightly more energy in the finishing region but that's the beauty of this IEM.
Stage is one of the most developed one with the OD200. Very good instrument placement around the head with very good Z axis placements. Very good sonics with good back and foreground contrast.
Stage is slightly wider on the EA1000 but it doesn't have much presence on the back of foreground but it's more Vivid sounding thanks to it's realistic contrast and cleaner instrumental definition.
