Introduction :-

The KZ Castor is an iem from KZ. Now there are two versions of these available one is the black colour (bass edition) and another is the silver colour (harman edition)

The one I am going to review today is the black colour bass edition.

Build quality, Comfort and Accessories :-


- These come in the usual KZ box.

- The packaging is very simple you get the IEM, cable with mic, KZ starline tips and a sim ejector tool for changing the toggling the switches.

- They MSRP for them is $15 but they can be bought from $10 or $12 too depending on where you buy them from and what sales re going on.

- The iems might be tad big for many

- The nozzles also might a tad big for someone with small ears

- The cable is quite good for the price.

Sound signature :-


- Well all I can say is BASSS!!

- If you are a basshead you will love this iem!

- There are 4 switches the first two switches controls the bass that is toggling the first switch gives a bass boost and toggling the second one gives another bass boost. The 3rd and 4th switch gives you a boost on the mids and treble a bit.

- I used the configuration UUDD for the review that is maximum bass while keeping the mids and treble stock. The reason I didn’t mess with the mid and treble switch because I find them to be quite satisfying in stock setting.

- surprisingly the switches works quite well specially the bass switch which works really well.

- The basic tuning it follows is the harman curve and the UUDD configuration gives it a huge bass boost as you can see from the graph.

- All I can say is that everyone needs this as the bass in these are just fantastic for the price.

- Every time I listen to this I grin because of the stupid amount of bass these has. It is just so enjoyable.

- Even if you are someone who isn't a basshead or doesnt enjoy bass the sheer ridiculousness of the bass here will make you smile.

- Not only is the bass ridiculous here what surprising is it is very well controlled and all the other frequencies works well in tandem.

- This is great for EDM, Rap, Hip – Hop it is an absolute treat to listen to bass heavy songs with these.

- Talking about the mids they are quite ok for the tuning and the price.

- Male vocals are in the background while female vocals are quite good.

- Treble is quite good for the price but they get shouty at higher volumes.

- One of the reason I don’t use the last two switches is because the stock treble I find it to be quite ok and goes well with the bass.

- The treble does lack extension and would have love to see that extension on the treble region a bit, again these are severe nitpicks for the price and sound it is targetiing

- the soundstage is below average although it does improve if you toggle off the bass switches to DD position.

- the imaging is ok for the price nothing great. Its bang average



Gaming -

These do perform average for gaming. For the average sessions these are ok but I wouldnt suggest them for gaming use along

Recommendation:-

- I think everyone should have them. I know bit of overstatement, but the bass on these just made me grin all the time. Its ridiculous and these are awesome at that. Even if aren't a basshead (which I am not) and you don’t like bass the sheer absurdity of it is quite an awesome experience.

- The super low price point of $12-15 is quite attainable for most and I highly suggest any audiophille getting them and try it out. For the basshead out there this is a must buy.

- Although this is a good Iem, Many wont try it because of KZ's reputation. KZ needs to work in their marketing overall, like labelling a $12 iem as a $1000 killer and make a show of it.

Or just comparing iems directly head on and saying ours is better.

They need to rather make a good iem and let it speak for it, like the castor bass is a good iem for the price. But many will avoid it as it is from them and they have had a bad reputation from those marketing.
