Pros: Great overall sound, HUGE bang for the buck, nice looking IEM, works well with most set ups
Cons: can be difficult to get an proper insertion (isolation)
For the price somewhere between $150.00 and $180.00 USD, there really isn't many other competition for the price. They really get the job done well. Can get a little stale in sound sometimes but that's really a rare case. These really are great!
Great sense if air in the treble (one of the best I've heard) with great detail and extension (sibilance was not a problem for me personally).
Fairly flat mid range that is true to the recording.
Very quick impact bass (especially for a dynamic driver) that's slightly north of neutral with great extension and accuracy.
Wide soundstage, lacking a bit in height and depth, but again with pretty accurate imaging.
Overall a great tonal balance and a very natural sound signature that is capable of handling most genres fairly well. Having that in mind plus being one of the most detailed iem in the price bracket (and honestly competing with iems hundreds of dollars greater in price), Vsonic has a winner here. Those looking for more low end have the option of the bass edition which is a great option to have.
