To many audiophiles, this is the point where you'd stop. Get close(ish) to endgame with the NiceHCK Rockies, an IEM making waves in the hobby as one of the best-tuned IEM under $1000, and arguably at any price point. Delivering a balanced bass, smooth treble and clear mids, the Rockies achieve a sound that feels both natural and engaging. Hangout.Audio pairs the Rockies with the CrinEar Protocol Max, a ludicrously powerful and remarkably flexible pocket-sized DAC-amp that lets you fine-tune your sound signature to perfection. The Protocol Max allows you to switch seamlessly between ECO mode for energy saving and BOOST mode for maximum output performance. Together, they form a future-proof bundle that sounds incredible and stands strong for whatever comes next.Find the step-by-step guide on how to upload your PEQ profiles into your Protocol Max HERE.
