The first time I listened after the burn-in, the W4 greeted me with neutral tonality. There is no boost or excessive energy anywhere in the frequency range; bass, midrange, and treble are equally represented, yet the overall presentation is lively and energetic.

Although the bass is flat, neutral, and extended, it is not the tightest, the most detailed, or the most textured I’ve heard. There is good punchiness in the mid-bass and good rumble in the sub-bass, but the grip or control of the W4 over the IEMs and the headphones is loose.
