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..
Excellent
Sound not bad average
The IEM's have a decent balanced V shaped profile & the manual EQ settings are quite useful.
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.

Very helpful in maintaining type C cable
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.
Excellent studio quality clear natural audio with good enough bass, well-balanced thanks to the audio store team and Pritaam Halpawat sir, great customer service, and 100% authentic genuine products.
Great
Nice I like it.
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.
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.
have been using this for more than 2 months. The audio is very clear specially the vocals and the bass is also decent overall very balanced sound
At the price, can't complain.
Perfect sturdy piece to carry(not in pockets) anywhere
Truthear Hexa fits perfectly.
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.
DAC sounds perfect when you connect it with laptop or PC
has a less sound when you play with Smartphone.
Other than this the IEMs are great
Great fit to ears
This DAC is awesome and a perfect value addition to my IEM. It enhances the quality of the audio and make it a bit loader as well. Buying and its a must have accessory for the audiophiles.
Powerful, stylish, worth the price, good mic quality, the best in the range!
Powerful performance with good looks
I like the simple design without any text. The material is good. The size is perfect for carrying DAC - IEM - any other accessory.
