🎧 KZ Castor Pro IEM – Review
🔊 Sound Quality
The KZ Castor Pro delivers clear and detailed sound with excellent separation across lows, mids, and highs. The decent thumping bass is tight and controlled, giving energy to tracks without overwhelming the vocals or instruments. Its super-balanced tuning ensures a natural, enjoyable listening experience suitable for all genres.
🎚 Unique DIP Switch Equalizer
What sets the Castor Pro apart is its DIP switch physical equalizer. With up to 16 different tuning options, it allows listeners to adjust the sound profile on the go—boosting bass, enhancing treble, or keeping it neutral. This feature gives it a level of flexibility rarely seen in IEMs at this price point.
🔇 Noise Isolation
Although it lacks active noise cancellation, the design offers an excellent passive seal. The snug fit ensures that outside noise is effectively blocked, making the listening experience immersive and ensuring ANC doesn’t feel like a missing feature.
🎼 Hi-Res & DAC Performance
For those using Hi-Res lossless audio, pairing the Castor Pro with a DAC is highly recommended. The extra power and clarity from a DAC enhance the already impressive soundstage, detail retrieval, and overall dynamics, making the listening experience truly premium.
💰 Value for Money
At its smart price, the KZ Castor Pro punches well above its weight. It combines detailed sound, punchy bass, balanced tuning, and innovative features—making it a strong choice for both audiophiles on a budget and everyday music lovers.
Have been using these buds for like an year now, they gave me a great time all that while, only recently the cable started getting green and there was an issue with audio drop on even a slight movement (like every earphone ever), but still a great investment for an year.
Got this as my first iem from audio store.. much much more worth than the price.. the bass!!.. my gawddd, it's something which is gonna surprise you.. I got it paired with the moondrop echo a dac.. and trust me, couldn't have asked for anything better.. and the delivery was done to me in kolkata, just within a day.. remarkable job audio store!♥️
Loved the new gear they sound absolutely phenomenal and mind if say the looks and aesthetic of the KZ Castor Pro is underrated for its price, as a newbie I was a little hesitant to jump in this rabbit hole, but it was worth it. Shoutout to The Audio Store to build up my courage, they were very helpful as I was placing my order I fumbled and they responded very positively and helped me correct my mistake. Thank You

1999 is nothing the engineering is perfect of this IEM,,,
Amzing product
Love the way it sounds rich in every range perfect for beginners but if you're not a bass head go for non bass varient.
This is my first ever IEM that I purchased after research of couple of months. And I can say that this was a good decision on my end. Cable is good. Buds look stylish. Comes with a small carry pouch and 6 pairs of ear tips. Sound quality is awesome. Love the instrument separation. Customisable EQ gives them versatility. You can actually experience how other IEM sound just be playing around with the EQ.
Actually, l'm new to this IEM world. Such an amazing product. If you are new to iem just as me, I would highly recommend his product to try out. The OG. There are 16 types of tuning options to play around and explore your favourite music in a new way and the build quality is also pretty good. Overall a nice product 👍.
Good sound
5/5 Mids and Highs
5/5 Well balanced Bass, doesn't overpower the music
5/5 Design look premium and classy
They are quiet heavy and huge
Its my first time buying an iem and it sounds sooo good the design is good the wire can be improve, the bass is somewhat missing and the app has some glitches regarding equalizer. Otherwise this iem is better than my tws. I really like it.
Good

This DAC is performing quite well. No heating or white noise issues for me. I am using it with EDC Pro and Castor Pro Harman Target and noticing a good significant upgrade in overall frequency range. I am loving this DAC so far. Build quality is also good at this price range, let's see how long it lasts.
I ordered my first pair of IEM's through The Audio Store and the service was great. Got my package within 5 days and had some questions and their customer care is really active and I got all my queries solved. Great experience overall and I have already recommended Audio Store to my friends.
Went thorough tons of online reviews for a purchase of Desktop DAC+AMP. FOSI K7 was kickstarter but reviews about it was fantastic.
Grabbed it without Blinking twice from TAS. As usual it was a next day delivery.
Fosi delivers crystal clear sound both on Headphones and IEM . Driving power of it crazy.
No doubt it reached my expectations ! The sound quality is really good and gaming experience is also good ! If convenience doesn't matter and sound quality is your priority, you can choose this, it's all rounder IEMs !
Excellent sound
Have been using these buds for like an year now, they gave me a great time all that while, only recently the cable started getting green and there was an issue with audio drop on even a slight movement (like every earphone ever), but still a great investment for an year.
Its geat, the build quality is nice, the wire is preety hard.And quality is sick
Great IEMs
