ZZA K8: $40 after clipped coupon Amazon
Pros: Completely insane value for the money. Comes with 2 metal body wireless microphones that are USB-C chargeable. Comes with Chinese labeled infrared remote control. Has voice delete function that works quite well. Adjustable microphone reverb. Pretty good build quality. The default EQ is the most balanced, the other two sound muffled.
Cons: Very V curve frequency response, can be harsh in the treble range. Treble is boosted a good +10dB. Midbass is recessed. Slight distortion issue at all volume levels due to the bass high pass filter being set too low
