Being a brand renowned for their refined use of dynamic drivers, the VSonic GR01 earphones are Vsonic’s first approach to Balanced Armature technology. And as one might expect, the outcome is extraordinary; for many, the best implementation of Knowles TWFK driver (also used in models such as Audiotechnica CK10, Ultimate Ears 700, Fischer Audio DBA02, Brainwavz B2 and Rockit R50) to date.


With its minimalistic design and Vsonic’s usual tips variety, this is an extremely comfortable earphone to wear, allowing deep insertion and an extremely good sealing, which make it an ideal choice for use in any circumstance at really low volume.
The crafting is really premium, which becomes obvious in the aluminium mechanization, materials and the class it displays. You’ll notice their high quality since the very first second of use.


As for sound, the VSonic GR01 GR01 stand out for their great deal of detail. Precision, instruments separation and a great linearity merge to deliver the most HIFI sound possible. Despite bass frequencies not being its trump card, they are quick, precise and -within its design’s possibilities- have a certain extension. In fact, they will be successful as long as you don’t ask for very high pressure on the lowest frequencies. Mid-range is excellent, in detail as well as in texture and timbre. Both male and female voices stand out as extremely precise. Despite these being particularly warm-hearted earphones for the TWFK driver parameters, treble is the specialty of this earphone, coming across incisive or smooth depending on the case, but without sibilance or stridency.


The VSonic GR01 in -ear headphones are exceptional for a large number of audiophiles. Only those seeking big bass, the most analytical fans and people who can’t stand deep insertion earphones will find them unfriendly. Precise and sufficient bass, spectacular mid-range and clear treble without sounding aggressive; linear, balanced sound with a warm touch for dualBA, a soundstage not wide but perfectly articulated and a simply astounding detail level.
