HIDIZS ST2 PRO Review -Chris Love

Hidizs ST2 Pro Nebula Review

Hidizs is a brand who are usually somewhere around the front lines of innovation and this new budget DSP cable and earphones certainly promises a large uptick in fidelity in a very portable and mobile form. One thing I notice about most Hidizs products is that they usually improve upon different tech that’s already on the market, and they usually do so at a competitive cost for the consumer. The ST2P seems primed to be one of those products. Made entirely for those who don’t have the funds to purchase some top-of-the-line dongle dac, dap, dac/amp etc. or for those who want a very portable and convenient way to listen to high resolution music.

DSP Cable

Build Quality 

The cable which came with the ST2P is a blue/black colored cable and the look is flat out cool. Hidizs did a nice job selecting the materials used. Of course, these cables are DSP (digital signal processor) type-c cables to be used with any type c Android, Windows, Mac OS, IOS, or Harmony devices. The cables also have a working mic with a multifunction button controller. The actual build is impressive enough. Certainly, better than any other DSP cables that I have on hand.

Cable Features

In the case of the ST2P, Hidizs decided upon an actual very high quality dac chip which was somewhat surprising to me when I first found out. That chip is actually the ES9281AC Pro which is one of the better small device dac chips, better than middle of the road and not one you’d usually find in a cable like this.

Additional Features 

Another capability of the ES9281AC Pro is that you can get a whopping 8x MQA unfolding which is nice for those who have MQA tracks.

How does it sound? 

The Hidizs ST2 Pro Nebula comes in with a definite V-shaped sound signature that emboldens and emphasizes the mid-bass as well as a certain lift within the treble region. If I were to characterize this sound in one word, I’d call it “energetic” first. However, this energy comes with a certain level of capped brightness that skews all notes crisp, well enough detailed and a solid note structure.

Nice job Hidizs 

I think one of the things you’ll find with this iem/cable pairing is that the treble exceeds what you may be expecting. Now, I’m not saying that it pinches above its price, or that it far out paces sets within its price point. But I am saying that Hidizs did a fine job in recreating this area of the spectrum. You’ll Gear very good detail retrieval which has very solid micro-dynamics picking up even the finest minutiae. Obviously, in Ultra complicated tracks you won’t get the same results being that this is a single DD. However, for a single DD at this price I still hear very good instrument separation in the treble region, and it can take on some very fast paced tracks too.

It is too good to pass up for those who really need a good workout set, a good work around the house set, or just a set which you want hi-resolution audio at a cheap price. It’s actually a great starter set for folks getting into the hobby too. I feel that there’s no question whatsoever if the Hidizs ST2 Pro Nebula is worth the cost of ownership. Absolutely it is. Even at the much higher price of $89 it is still a good deal as well. The reason being is that this set is a two-for-one. You have the iems which are tuned well in the first place. However, what’s even nicer is the fact that you now have a very high-quality cable which can be used with any iem ending in either a 2-pin or mmcx termination (depending on what you are getting). Or just buy the cable separately! It’s an amazing DSP cable and easily the best I’ve heard to date. In fact, I just got the Tanchjim Bunny (brand new) and the Hidizs cable far outshines the Bunny’s cable in overall DSP cable skill and fidelity.
