I will be brief. Because as much the sound has been analyzed fairly fairly on the previous tests, there is a point to highlight, especially on intras of this price with a small Parenthesis concerning their high ranges, Platinum Grace.
What is the point of having a good sound if the manufacturing quality does not follow! Catastrophic machining, deplorable finishes with deviations of adjustment unworthy of a pair of intras at 5 dollars. A vent has even been forgotten to be pierced! I have never seen this.Finally, accessories that were not included because it is an oversight. The photos speak for themselves! Even my Grace Platinum have platinum veneer which disintegrates after a few months. Knowing that I don't use them often! In short, it had to be mentioned all the more since, sound level, there is Alternatives. And much better manufactured. These intras were purchased with my money, and were returned for a refund.
