Hey everyone,

The ZISHAN Z4 is a portable music player, light and small with strong specs. Thanks to brother Abdullah, who sent it for testing. Dual ES9038Q2M DAC chips, a TI OPA1622 amp you can swap, and 4.4 and 2.5 balanced, 3.5 single ended and 3.5 line out. Bluetooth 5.1 with a Qualcomm QCC5125 chip supporting LDAC and aptX HD, a 4200 mAh battery that gives about 8 hours, and SD card support up to 256 GB. It was $100 at the time of the review.

Who is it for?

  • As a music player only, for anyone whose IEM or headphone is warm or dark, and for trebleheads.

Strengths

  • Separation is excellent.
  • With warm IEMs it lowers the bass and brings them closer to a natural sound.
  • The price is amazing for a player, and the software is simple with a 10-band EQ.
  • I think it puts out between 400 and 500 mW (from my testing, not the company): it drove the TinHifi P1.

Weaknesses

  • The sound is bright overall, and with neutral IEMs it gets harsh, with the upper mids and treble stronger than natural.
  • The soundstage is small, and small details need more volume.
  • As a Bluetooth DAC/amp it’s bad: vocals sound like they’re behind a plastic bag.
  • You can control the volume on the line out, and its sound signature carries over to the external amp.
  • As a DAC only, a $30 dongle beat it.
  • DSD files lost detail.

Verdict

It’s only good as a music player: I don’t recommend it as a Bluetooth DAC, a USB DAC or a DAC only. I recommend the 4.4 output.

Note: this review is from 2022, so price and availability may have changed.
