Comfort :

Even though i have medium/mid-big ears, well in my experience it is one of the most compfy iem i ever used, the build quality is awesome! the fitting is perfect the weight is very light it is like not even there! so its obviously good!


[Note : i used the KZ provided FT01 ear tips]

the stock ear tips is like every other average KZ eartips nothing special about it so i did not used it instead i used the FT01 tips. which is great in my experience! it is kind of like having active noise cancelling ! it cuts off 60% of the external noises!


SOUND QUALITY :

I am going to say in this budget it offers more than its price! specially under 20$! here is more about thesound quality!

Bass :

Well this version of the Castor is not biased for bass enthusiast but i will say its well balanced and well controlled, not overhelming ... it does not provide skull crushing bass. after enabling switch 1 and 2 the bass increases slightly, sadly i did not used it much! but in space marine the foot step and grenade explosion is replaced with bass which i did not liked!

MID :

The mids/vocal, offers a good level of details. male vocals are sharp but sometime thick in my opinion... Female vocals, on the other hand, are sharp and detailed, making them a joy to listen to. There were no issues in the gaming section : the vocal sound separation is really good! in World of Tanks, PUBG, Delta Force, World of Warships Legends. In Dragonforce and Linikn park the vocal [ Zp. theart {Dragonforce} and Chester benington {Linkin Park}] was a bit thicker than usual. Female Vocal are sharpy

Treble/Highs :

This is the best part about this iem, it provides crystal clear highs, has depth and bright sound signature. The sound separation quality is great.
In dragonforce the guitar solos are greatly well controlled and separated, in the "through the fire and the flames"
there was a slight muddiness in the end of the solo of herman lee but it is not a deal breaker,
the piano chords in sound of silence is covered [disturbed] is perfectly produced. hence i enjoyed listening to other musics! Specially when you play World of Tanks most of budget iem replaces track effects with sub-bass but in this iem it is rock solid highs. In fps gaming the foot steps in grass which most iem replaces with kind of bass i do not like, gun fire sound is also covered by bass which did not happen in the case of Carol! the gunshots and grass steps sound is crispy !

Final Verdict

The KZ Castor Harman is a fantastic budget IEM that punches above its weight. It’s not perfect or godlike, but for under $30, it’s hard to complain.
