HIDIZS ST2 PRO Nebula 4

With everything these days being wireless it is easy to forget that although Bluetooth connection is super convenient it isn’t aways the best choice when it comes to sound quality. The ST2 PRO Nebula from HIDIZS are some budget friendly IEMs that use a dual-magnetic circuit dynamic driver and offer tuning filters that allow for some level of customisation. The outer casings feature a semi-transparent resin shell that looks pretty cool, reminiscent of the 90s when everything technical was see through for some unknow reason.

They have an ergonomic shape and come with three sizes of silicone ear tips to find a comfortable fit. The metal nozzle and interchangeable tuning filters add a touch of premium feel, letting users adjust the sound profile to their liking. The stock cable is decent, though an upgrade might enhance performance further. Thanks to their lightweight build, these IEMs are comfortable for long listening sessions. Noise isolation is decent but depends on ear tip selection, there is not active noise cancellation. You don’t have to worry about battery life though thanks to the wired USB-C connection.

With a 10mm dynamic driver, the ST2 PRO Nebula delivers a well-balanced sound that aims to have more of a boost around the bass and treble. We found the bass was good and punchy, but some (not us) may find it slightly overpowering. The mids were slightly recessed but still clear however we found the treble was a little sharp at times so purist might be struggle here. The volume is good and can be cranked up to an ill advised 108dB. The inbuilt DAC is a lovely addition at this price point, helping you enjoy the music as it was creating by converting the audio from digital to analogue sound waves.

For the price, the HIDIZS ST2 PRO Nebula is a solid choice for budget-conscious audiophiles. The tuning filters, stylish design, and engaging sound make it a competitive option in its range. While the bass and treble emphasis may not suit everyone, those looking for an energetic and detailed IEM will find a lot to like. RRP £42.51
