It has been nearly a year since NVX introduce EX10S to the market. Although it has made its debut within the audiophile community already, not much is really known about its sound quality and true potential.
Besides, it is notable that EX10S shares many technical similarities with Vsonic GR07 mkII, which is one of my most favorite dynamic IEMs of all time. GR07 mkII is well-known for its great sound quality, inverted polarity, unique pivoting nozzle design, and usage of a flexible silver cable. If EX10S's sound quality turns out to be as good as that of GR07 mkII, the IEM shall be a great deal for the price.
CON: The absolute polarity is inverted.
IN CONCLUSION: As a new comer, NVX has made a kick off quite soundly. As such, EX10S is nearly half the price of GR07 mkII, but the sound quality is equivalent. If anybody, who likes the sound of Vsonic, is low on budget, I'd recommend NVX EX10S over anything, period.
