The company states that the ST2 PRO results from” hundreds of hours of testing and engineering work” and offers an innovative new way to listen to audio from today's digital devices, including Macs, PCs or smartphones — including the latest iPhone 15, 15 Pro, and 15 Pro Max, portable gaming devices, Digital Audio Players (DAPs) and more.

The main change is swapping out the traditional mini-jack plug for a USB Type-C connector. Additionally, the IEMs feature a built-in flagship ESS ES9281C PRO DAC supporting audio files up to and including 32-bit/384kHz (PCM), DSD128, and MQA.

We are assured that the digital wired connection ensures zero latency, making the ST2 PRO ideal for playing games or watching videos.

Hidizs adds that the ST2 PRO delivers a musical, engaging sound thanks to their 10mm Magnetic Circuit Dynamic Drivers with a claimed frequency response of 20Hz to 40kHz, partnered with the IEM's bundled 1.2 metre 6N High-purity Oxygen-free Copper detachable cable.

Simply plug the SD2 into your Mac, PC or smartphone and your headphones into the SD2 to instantly improve the quality of your audio thanks to the in-built ESS ES9270 DAC, supporting hi-res files up to 32-Bit/384kHz (PCM) & ​DSD128.
