SIMGOT SuperMix 4 1DD+1BA+1Planar+1PZT Hybrid Drivers Earphones, HiFi in Ear Monitor IEM + Kiwi Ears Allegro Mini Portable IEM DAC, in Ear Monitor Amplifier

SuperMix 4 features a luxurious configuration of four driver types: 1DD+1BA+1 Planar +1 PZT. This carefully constructed four-in-one matrix acoustics architecture allows for precise frequency response adjustment and overall balance. Building on the success of the Allegro, the Allegro Mini was designed with the same dedication to high-fidelity sound but in a more compact and portable form. Both the Allegro and Allegro Mini excel in portability, but the Allegro Mini takes it a step further with its sleek, all-aluminum alloy body.
