Having purchased a VSonic GR07 BE and at a later stage a GR07 Classic out of curiosity, I was most disappointed with the build quality of these IEMs. Within warranty period, the Bass Edition had issues and after warranty ended, the right driver simply died.
Within ten seconds of using a hair dryer, the casing popped open, the inner housing of the driver had falling apart, I reassembled/glued together but to no effect. My GR07 BE was dead.
The issue was because the material of the casing, this type of plastic just doesn't work well with contact adhesive.
After net searching for am IEM which may seat between GR07 Classic and the BE version, I came across some information for the Vivo XE800.
Was very sceptical after been burned numerous times from "those" Chinese sellers, my compatriots but with absolutely no affiliation.
I purchased a Vivo XE800 for just under US$20.
I was pleasantly surprised with the Vivi XE800.
The Seller's product description statements tells about "these fakes having non movable nozzles", this is a misinterpretation due to translation, what they were attempting to say was "fakes do not have movable nozzles". The item received did have movable nozzles, not box, rigid pouch and two useless spare pairs of buds (one tiny and one too big). The attached ear buds were a perfect fit for my dinky ears.
This Seller (chosen due feedback rather than price) have further reduced this Vivo XE800 to US$18, lucky for me, although it would not have mattered, as I went and purchased two more for Spares/Mods whatever.....
I am not saying the VSonics are no good, I'm just saying their quality control is atrocious for the price.
Would you risk paying over US$100 for an item which may very quickly become useless or pay US$20 for an IEM which have better build quality and arguable better aesthetics (I am so vain) and sound.
The vivo ex800 uses the gr07 driver so technically it is vsonic
