this is my first wired IEM. I was searching for good budget, reliable set of IEMS from good brand. My search ended with KZ EDX pro. I am using with galaxy S23 with google USB-c to 3.5mm (1st Gen) DAC adaptor. (As I have got this with Pixel 2Xl in box). First impression of KZ EDX pro is excellent. We can feel every bit details that a musician would like to pass to our ear. Great budget buy. I am not familiar with other brands and premium IEM. I am not audiophile to judge at that level. But I am really impressed by its sounding. Each and every beat we can listen. My spouse also tried it and said impressive... (as she is using iPod (4th gen) and iPhone 13 as daily driver) I have also checked this with iPod Touch and iPad (5th gen). its sound as it should be. One thing I highlight please use with proper DAC adaptor if your music device doesn't have 3.5mm jack. I am getting some sort of hissing sound when connected with google dongle. Tough Getting proper amplified sound through it, but sometimes getting cracking sound while listening which is annoying. It's not the case with iPad with 3.5mm jack. So overall good purchase and quite satisfied with performance at this price.
