The title says it all. After listening to many TOTL IEMs in the past 6-7 years, my endless chase for achieving audio nirvana is met with Fir Audio Xenon 6 (XE6). While several of my past & current IEMs such as 64 Audio U12T, Final A8000, Sony IER Z1R & M9, Sennheiser IE800s & IE900, Shure 846, KSE1200, JH Audio Roxanne, CA Solaris, etc. were good at one thing or two but I have never felt such emotional connect with any IEM like this. It's special, really special.
I know you can read tons of detailed professional reviews on XE-6, so I don't want to fill this space with the technical detail of XE6, audiophile jargon, and stereotype statement. I only want to share XE's unique factor which made me stop chasing flagship after flagship and start rediscovering my library.
A short detail about my setup & my musical preferences. I generally listen on my desktop - RME ADI 2 and Chord Hugo and like to listen to EDM, Country, Pop, and occasionally Bollywood.
When I first listened to XE-6, I found it strange. Frankly, when you get a TOTL IEM, you expect a more safe and agreeable tuning. But XE6 is not like that, it has a very unique & superbly dynamic presentation of sound. Right from bass, which is so textured and rich that it can't be explained but only experienced. It's an acquired taste for sure, but once you dive into it there is no looking back. Coming from IER Z1R, I can vouch that this is the best sense of bass I have ever experienced in an IEM. The bass is physical - one can feel it, without being bloomy. Jumping on mid-range, have you ever thought about listening to something like Billie Eilish's Happier Than Ever and felt the warmth of her breath in vocal? Yes, it is something that I felt when I hear this song and many more such songs in my albums that gave me goosebumps on XE6. Mids on XE6 are pure magic. Vocals and String instruments shine on this IEM. The treble is endlessly extended, with lots of detail. It's very precise and defined but non-fatiguing.
Overall, this IEM is certainly neither neutral nor analytical. But it's unlike any other IEM that I have heard. For me, it is an emotional, very emotional presentation of music and that's what I expect when I listen to my favorite tracks. I wanted to go back to those memories which are encapsulated in those tracks.

FIR Space : Let the FORCE of MUSIC be with you.
Being in This Hobby for last 25 years & owning more than 70+ & auditioning more than 100+ iems, i concluded my journey with this beautiful IEM to explore new verse.
Xe6 will make you cry when you hear those sub & mid bass rumble, the air will shine with no shrills & mesmerizing visceral vocals not hit you on your face.
Example this: Jee karda by Divya Kumar from Badlapur.

🎧 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

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.
