Let’s enjoy our favorite music with style with the all-new ECCI YST-03 triple driver hybrid set of in-ear monitors. With stunning Jewellery like looks, the pair features dual customized BA drivers and a 10mm dynamic driver unit. YST-03 ear shells have a PVD-gold plated face panel frame with dyed abalone shell making a beautifully textured look.

A Pure & Musical Sound With Triple-Driver Hybrid  Configuration:-

ECCI YST series features a hybrid driver configuration. The series pursues a natural and pure high-resolution sound response. YST-03 is equipped with a three-driver hybrid configuration housing dual customized high-frequency balanced armature drivers and one 10mm dynamic driver. The drivers are arranged in a two-way frequency crossover using physical frequency division and RC circuit frequency division techs. This enables the pair to produce an accurate sound with good clarity throughout a wide frequency response range.

Looks That Catches The Eye In An Instant:-

ECCI has featured a PVD gold-plated frame on the beautiful face covers of the YST-03. The face covers have a dyed abalone structure with a high-transparency resin shell for a jewelry-like textured finish. Each face panel gets a unique look of its own that makes each and every single unit of YST03 stand out on its own.

Comfortable In-Ear Fitting:-

ECCI has designed the ear shells of the YST-03 IEMs in an ergonomic shape. The compact cavity structure is crafted after a study on a huge data of human ear canals. The pair conforms to the shape of the human ear, supported by memory PU ear hooks near the connectors, the pair sits firmly into the ears and promises a comfortable wearing experience for long listening hours.

Professional Tuning Adjustments For High-Resolution Sound:-

With the help of professional and experienced acoustic engineers, ECCI has tuned the YST-03 IEMs for a detailed and spacious sound response. Don’t go on the compact size of the YST-03 shells, the pair produces a large sound stage with good clarity and a smooth response throughout a wide frequency response range.

High-Quality 2-Pin Stock Cable:-

YST-03 IEMs have a swappable cable design. The pair adopts standard 0.78mm 2-pin connectors that allow the users to change the cable to their liking. It’s a high-purity single-crystal copper silver-plated cable with a 3.5mm termination plug.

Easy Drivability:-

ECCI has designed the YST-03 with easy drivability. The pair doesn’t require much power, it can be powered fairly easily using smartphones. For best performance, we recommend using a Hi-Res player because it will have better decoding and amplification.

Good quality, but…
Size: 60 Count (Pack of 1)
Good quality supplement for the price. I started to take it for my joints as I have an auto immune disease. My only complaint is that in order to get enough EPA for it to be effective for that I have to take a minimum of two a day but when I do that it makes me a little dizzy and upsets my stomach. I’m not sure if that’s because I’m on high blood pressure meds and because I don’t have a gallbladder, so I just take one a day of it for general health. I may try another brand just to see if my body has the same response.

Dropped LDL by 38 at one year check up
Size: 60 Count (Pack of 1)
I am a 48 year old female weighing 126 lbs. I want to praise this product for reducing cholesterol levels. I have seen the cardiologist to be proactive since my dad died of heart disease and because it runs on both sides of the family. My cholesterol levels have been borderline high for several years but not to the point of needing medication. In April 2025 it was the highest levels so far. I had been eating healthy cereals and exercising at that time so I was surprised it had increased. I have taken this supplement daily for a full year without missing many doses. I just had my yearly check up on April 1, 2026, and my total cholesterol dropped by 37 and the bad LDL dropped by 38. I am very please with my results. All my levels were in the optimal range except the LDL and It was in the nearly optimal range per the Labcorp graph and total cholesterol was in the acceptable range. I have not exercised in 8 months and I eat a lot of fast food, so this product is the only explanation for the improvement. I also started the Megared CoQ10 about 5 weeks before my labs but it wouldn't be long enough to be that helpful yet. I am going to stay on the CoQ10 in addition to the Megared 4 in 1 product to see if it further lowers the LDL to the optimal range next year. In one year with no diet changes or exercise: Cholesterol total went from 228 to 191 LDL Cholesterol went from 161 to 123 The only thing I do not like about the product is the price but with those results I can't complain. It is worth it.
