Kiwi Ears Septet in Ear Monitor, 1DD + 4BA + 1 Planar + 1 PZT Quadbrid IEM Earphones, HiFi Wired Earbuds + Kiwi Ears Allegro Mini Portable IEM DAC

The Septet utilizes the tried-and-true 10mm composite dynamic driver to power the sub-bass and bass. The large diaphragm dynamic driver outperforms other driver types for a powerful and deep sub-bass rumble down to 8Hz, and delivers a sub-woofer-like bass signature. 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.
