The Mpow CH1 have sub-par peaks and dips performance. There’s a bit of a mismatch between the left and right drivers throughout the range, so objects may not be accurately placed within the stereo image. The peak in the high bass adds a boomy, muddy quality to the mix. The dip in the low mid thins out vocals and lead instruments, while the peak in the mid and high-mid makes those same instruments honky, harsh, and boxy. The dip in the low treble hurts the comprehensibility of vocals and lead instruments, and the peak in the mid-treble makes sibilants piercing and painful.
