Hello everyone, I hope you’re all doing well! I've shared my full review of, the Hidizs ST2 Pro Nebula. The ST2 Pro combines a single dynamic driver (DD) earphone with a DSP cable, creating a well-balanced and easy-to-use audio setup. The ST2 Pro features a high-performance DAC chip, the ES9281AC Pro, which is used in many premium dongle DACs like the Questyle M15 and others. This chipset is known for its impressive capabilities, and it's rare to find DSP cables equipped with such a reputable DAC. Additionally, the device delivers 70mW of power, which is more than enough to drive most IEMs with ease.
Over the last few weeks, I’ve carried the ST2 Pro with me everywhere. It’s reassuring to have a reliable IEM and cable combo that guarantees a solid listening experience on the go. In my review, I dive deep into the product, highlighting both its strengths and some of the subjective drawbacks. While there’s a lot to explain about the sound quality between the earphones and cable, I’ll just touch on a few key points here. Together, the earphones and cable produce a clean, energetic sound with powerful bass that’s tight and well-defined. The midrange is slightly recessed, but it’s rich in detail, offering a high-resolution, airy sound with a touch of sparkle in the upper mids. The treble is well-extended, resolving, and has a nice bite and crispness to it. While there’s much more I discuss in my full review, one thing I can say is that this setup is ideal for newcomers to the audio hobby or anyone who needs a dependable audio solution for the gym, work, shopping, or casual listening. Hidizs has created a fantastic product here. If you’d prefer, you can also purchase just the cable, which is available in both 2-pin or MMCX connectors and comes in two color options. Overall, I’ve been very pleased with this setup—it’s simply easy to enjoy.
