Lovely sounding straight out the box. Stock tips are the most atrocious ever. Only foam tips are even usable.
Its basically a budget bravado which is even more tip dependent. Impactful bass, smooth response in the mids and treble with no sibilance. With wide bore tips, the bass is thunderous with vocals slightly behind the vocals with the treble slightly lifted over the vocals but behind the bass. With final audio tips, the vocals get kicked forward, now in front of the bass and slightly behind treble, but, the bass is still awesome and hits like a truck. I am loving every second of it xD. This is very close to my ideal sound signature. Easily "tweakable" with a cheapish cable.
