KZ is a highly popular brand that has gained a lot of recognition in the audiophile community for its affordable yet high-quality In-ear monitors. They also offer after-market upgrades for IEMs, eartips, carry cases, and TWS wireless adapters.
The level of detail... Unbeatable. The IEMS form a seal in your ears.. The thump hits. Basslines are pristine.. Highs are crystal clear, perfectly sharp. Vocal forward.
Listen to Hotel California in these earphones, truly mind blowing. Must Buy. Worth every penny..

Castor pro x
Hey,
I recently purchased the KZ Castor Pro X, and the left side isn’t working properly — the sound is very low.
I’ve already tried switching the buttons, but it didn’t help. 😕
This is my first IEM, and I’ve used it for less than a week. Please help me out.

I love the sound quality which top-notch in the tier. But I don't feel any difference when i switch the hardware Equalizer. And i personally think that wheter there is a additional driver for low frequency but still the clarity of vocals and mid faded bass.

Probably the best IEM you can get for 2500
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.

Best for the budget (~929 rs)
I was using Sennheisers CX80s with Samsung Galaxy A52s and it has 3.5 mm jack but the sound quality & output levels are very bad. So, I had to get a DAC and I watched a lot of reviews before making this purchase and one thing I can say is the sound quality is better than Apple's dongle becoz it only supports 16/44.1-48KHz .
The cable is super flexible and supports both Type C & Type A connection for PCs.

Summary review of the Mega5Est
These IEMs have a unique personality and it does match the many YT reviews that I watched before making this purchase.
The tuning is very neutral leaning slightly bright. These IEMs will present all instruments and everything that is present in the mix without emphasizing. Bass and sub bass present without any mud or overpowering of other frequencies. Mids are well presented, in fact these are all about the mids which are mostly neglected in favour of bass tightness and extended treble.
I found the vocals slightly forward but not harsh, in fact nothing is overpowering in the presentation here which may come across as boring but it is simply presenting the songs as is. You can easily drift off mentally while listening, the presentation is so neutral and focus back whenever you wish to.
Overall these are very solid IEMs good for analysing and casual listening both. Tuning preferences may be highly personal and there may obviously be many who may not prefer this kind of tuning but still this doesn't take any points away.
I am happy with the purchase and prompt delivery.

This IEMs delivers excellent sound across all music genres and is used daily. The unboxing experience is premium. However, a minor issue has been identified: the right-side IEM produces a subtle noise when tapped while worn, which may indicate a manufacturing defect.
