The Vsonic GR07X retains the form factor and design of the GR07 versions before it. It features a new driver (still biocellulose-based it seems) and allows for swapping the cable below the Y-split with a 2.5mm connector (snaps firmly into place, seems quite sturdy). Thus if the cable were to fail at the jack end, it should be possible to easily remedy that with any replacement.   Currently it ships with 2 included cables, 1 standard 3.5mm plug cable, and one balanced cable  with a 2.5mm plug end. I also got a pack of spinfit tips included with them...

    I was contacted by a Shozy representative and offered to evaluate and honestly review the Zero IEM, after letting it play around 200 hours of music. They were delivered to me free of charge, so keep in mind this potential bias. I will try to be as honest and objective as possible. I own several single dynamic driver IEMs, aswell as a few balanced armature designs.   I tend to prefer metal and rock music, aswell as soundtracks, and 80s music.   Design:   The Shozy Zero is a very small, very light-weight IEM. The prominent feature is the...

IEMs I own and have used extensively before: Vsonic GR07 (single dynamic), Vsonic VC1000 (dual BA), Etymotic HF5 (single BA) (all around or slightly above $100).     Fit and Comfort The housings were smaller than I was expecting, very light-weight. The cable closest to the housing has a metal wire that you can bend to your desired shape around your ear. The IEMs are not ventilated, so can create a vaccuum feel in your ears with some tips. I am sensitive to this though and it did not bother me with these IEMs. Depth of insertion can be quite...

After owning the Vsonic GR07 Classic Edition for about 2 months or so, all I can say is these are absolutely brilliant.   Very articulate, fast/dry sound. These will extract details almost to a fault, to the point where classical music isn't realistically presented for the most part, due to overly in-your-face presentation. They are quite neutral, however have a full low-mid area and a 6.5kHz peak, a build to a 10K peak, then a dip around 12kHz and then another peak above that (se for example  innerfidelity for a detailed FR graph).   For...
