CES 2024 is underway and we’re already noticing a trend; high-end audio headphone and IEM solutions are going to be a huge focus at the show and it is all being driven by consumer demand for better quality personal audio products.

We think the market has already reached a saturation point where it is impossible to keep up with all of the new headphones, IEMs, DAPs, Dongle DACs and and TWS earbuds being released, but manufacturers are pushing even harder into the Head-Fi space hoping to capture some of the pie; which is admittedly rather small once you strip away Apple, Bose, Sony, JBL, Philips, Beats, and Sennheiser headphones and earbuds.

Apple’s transition from the lightning to USB Type-C connector on the iPhone has created a new opportunity for manufacturers who wish to offer forward thinking options for consumers. It’s going to be a huge market for brands if they can convince iPhone users that there is a better alternative to Apple’s AirPods.

HIDIZS have introduced the new ST2 PRO Digital IEMs represent an innovative new way for consumers to listen to their audio from today’s digital devices, including: smartphones, portable gaming devices, Digital Audio Players (DAPs) and more. 

Rather than featuring a traditional mini-jack plug, the ST2 PRO is equipped with a USB Type-C connector. ​

The IEMs feature a built-in flagship ESS ES9281C PRO DAC and offer support for audio files up to and including 32-Bit/384kHz (PCM), DSD128, and MQA.

Users can easily plug the ST2 PRO Digital IEMs into their Mac, PC or smartphone — including the latest iPhone 15, 15 Pro, and 15 Pro Max — to enjoy their favourite albums, podcasts, and more. ​

The digital wired connection ensures zero latency, making the ST2 PRO ideal for playing games, or watching video.

HIDIZS’ audio engineers have worked hard to ensure that the ST2 PRO deliver a musical, engaging sound thanks to their 10mm Magnetic Circuit Dynamic Drivers, frequency response of 20Hz — 40kHz, and 6N High-purity Oxygen-free Copper Cable.
