VSonic joined the upper-tier potable audio market a bit over a year ago with the introduction of the GR07 dynamic-driver monitor. The GR07 made quite a splash, quickly becoming one of the most commonly recommended earphones and maintaining its popularity to this day. My personal opinion of the GR07 was quite positive from the outset and it remains my dynamic-driver benchmark for entry into the top-tier club.
This year, VSonic is expanding into other market segments with the introduction of several new models. The GR01 is the first of the 2012 models to reach my ears and the subject of this review. It utilizes the popular Knowles TWFK transducer – a tiny dual-armature system used by everyone from Audio-Technica to Ultimate Ears. The GR01 is not your typical TWFK-based dual-BA earphone, however - the engineers at VSonic have put their own special touch on the design and sound. I was lucky to get a chance to compare the GR01 to four other earphones all using the same TWFK driver to see how special it really is.
The GR01 ships in VSonic’s simplified new packaging – a clear plastic outer box with cardboard and foam inserts displaying the earphones and obscuring the accessories. The accessory pack consists of 15 pairs of eartips and a padded spring-clasp carrying pouch. The tip set includes seven pairs of Sony Hybrid-style tips, all in different sizes, as well as 3 pairs of foam-stuffed Hybrid tips and 5 pairs of standard silicone tips, including a bi-flange. The soft carrying pouch is very well-made, probably the best I’ve come across, but I would still have preferred a clamshell carrying case like the one included with the 1st-gen GR07.
