There are suprises which make us Rethink our opinion on certain subjects. the VSD3S are such a suprise. was expecting something good due to the company's history and reputation but nothing prepared me for how they sound.....I own a few nice IEM, TFZ no3, NM Audio NA2 and NM2 and the Vsonic gave them a fight. the quality of sound , the presentation, the clarity, the fullness all are on par with the other way more expensive IEM and only sometimes do you hear that the others are better conclusion is simple, if you want an amazing earphone for the gym or to run outside get the Vsonic with full confidence
Everything all right, Thank you!
