Customers praised this budget IEM for "crystal clear sound" and "punchy bass" with Harman tuning. Many noted it's excellent for beginners, offering impressive detail, balanced vocals, and deep bass without muddiness. Tuning switches add customization. Some concerns: soundstage limitations, fit/comfort issues for longer use, weight, sharp highs at higher volumes, and inverted audio in gaming.
Very best audio quality each and every vocal was crisp and clear in future I will buy more Iem from audio store❤️
Sound quality is great as expected from iem.
Please skip those ears are tiny. Because it's very heavy and big in size. Also mic quality is excellent.
Great job on packing of the product. As a gamer I can say that, for fps games like PUBG , CS2 etc., Castor Pro is the best in under ₹2000
I had never used an IEM before, so this was my very first experience and I was genuinely impressed. As someone who loves music, I can confidently say this is one of the best investments you can make for audio quality. The sound is exceptional and absolutely worth the price.
To get the best possible audio experience, I would also recommend pairing it with a good-quality DAC, as it significantly enhances the overall output. ....
Aswome experience with kz castor pro harman target Bass edition I never heard that quality of
Bass My second experience with iem aswome
Superb iem
The IEMs are doing fine after 8 months of heavy use. they still feel as good as new. I use them every day. The sound experience of these IEMs is just so good for the price. I play a lot of games, listen to music, and watch multimedia content, and I get the same amazing, immersive experience across everything. If you guys love a lot of punchy bass, you'll love these for sure. Also, a massive W to The Audio Store for the great service.
It has a clean and bright vocals.
But while using with my laptop I felt a low volume even my laptop supports Dolby Atmos. I have using DAC Audiocular Spark you can purchase from audiostore else you can also buy it from Headphone Zone.
One final suggestion:
If you are not considering service buy from audiostore as they don't care much about customer(Personal Experience). I purchased this product on 11 th may after issue found on 15 th may returned and now it's 11 th june at 13:48pm they provided refund as store credits. Worst decision for me to purchase on audio store.
If you really want to upgrade to another IEM without any extra cost for the first IEM purchase. you can change your iem in your first 7 days for free of cost. so i recommend even if you make a small mistake choosing first iem you have an option.
These my first iems using it from last 2 months very nice very balanced sound
This is awesome. You can hear all frequencies individually with standard level. No comparison with earbuds or wireless headphone
The Castor Pro (Harman tuned with enhanced bass) is amazing if you love punchy sound. The bass has strong thump and depth, but it doesn’t overpower vocals. Music feels lively and fun, especially for Bollywood and EDM.
Vocals are clear, treble is smooth (no harshness), and overall tuning is well balanced. Very enjoyable for daily listening and workouts.
Verdict: Great earphones if you want powerful bass with good clarity.
I’m really impressed with the KZ Castor Pro (Harman Target). The dual 10mm drivers provide fantastic clarity and a really balanced sound that works perfectly for both gaming and music.
Big thanks to The Audio Store for the excellent service! The ordering was easy and the delivery was reliable. Highly recommended for any audio enthusiast! MORE ORDER FROM ME IN FUTURE

We take pride in providing excellent service and are glad to hear that your ordering experience was easy and reliable. We appreciate your recommendation and look forward to serving you in the future.

Really sound was very good
Review title has nothing to do with my taste in music. I just found these metal faceplated beauties a bit heavy, literally and sound wise as well. Tuning switches give you a slight touch of control. Value for money at the price point. Experience with the Audio Store was very simple and smooth and delivery was quick and efficient.
One of the best IEM.
Nice stuff music another level.
I have used it roughly 10-15 times and is good enough for the price but when it comes to comfort, It lacks a bit. I have been using Oneplus buds 3 for a long time and when compared to it, KZ Castor lacks comfort for longer durations
Nice
These are my first IEMs. After a bit of research, I decided to go with the KZ Castor Pro as my first IEM. I'm really impressed with the audio depth, the crispness of audio and the clarity and separation of instruments and vocals. The music feels much different than the usual TWS earbuds which I was using before! The packaging was good, and delivery from Audio Store was good! Glad to have officially entered the IEM clan!
I herd of them and brought them was concerned but the audiostore team was gental and the quality of product was superior
KZ Caster Pro delivers solid bass and a decent soundstage for the price, but the mids are just okay and not particularly exciting. Build and comfort are decent, making it a decent budget pick if you want more low end than detail.
For me, it wasn’t a major upgrade compared to the Realme Buds 2, which use an 11.2 mm driver. However, dual-driver earphones definitely have their own benefits and potential when it comes to sound separation and detail.
That said, earphones and IEMs are a completely different world to explore, offering a distinct listening experience altogether.
The product won't disappoint u.

I was impressed by fast and well managed delivery 📦 . Coming to moondrop space travel 2 ultra..one word awesome..I was searching for tws loud enough and quality sound and I am fully amazed by sound.
Very best audio quality each and every vocal was crisp and clear in future I will buy more Iem from audio store❤️
After using the Roseselsa Aurora, I can confidently say it's one of the best budget IEMs I've tried. The tuning is fun, vocals are detailed, the bass has good impact, and instrument separation is impressive. It's comfortable, well-built, and makes every song enjoyable. Definitely worth buying if you're looking for a quality IEM. 🎧⭐⭐⭐⭐⭐
Nice dac
I've purchased this kz edx pro 2 with mic and type c I've received in just 2 days and the product is absolute perfect and build quality and audio experience is so good I've loved it and the look also is so good, the quality of mic is good though compare to other mics audio is perfect and smooth for me.
I opened it fastly then at the end i saw take a video while opening sorry audio store. But tbh the wire quality is so good and delivery also came before expected date. If someone reading this comment the 1 reason to buy from audio store is they keep affrodable prices when compared to headphonezone and concept kart and offcourse amazon and the quality is also on top notch
Great little DAC! Clean, detailed sound with better clarity, tighter bass, and good instrument separation. Compact, easy to use, and a solid upgrade for any IEM.
My first pair of IEM and I absolutely loved it🥰
I’ll recommend the audio store and purchase more in future
The product has a sturdy build and the ring light adds a clean, aesthetic touch that enhances its overall look. Using it with my KZ Castor Harmon Edition feels like listening to my favorite song for the very first time, with sound quality that is clear and immersive. It works smoothly with both Samsung devices and Windows, and the customization options on Windows make it highly versatile. The quick delivery in just one day was the icing on the cake, making this a well-rounded purchase that combines design, performance, and convenience.
Pairing this Harman Target Version with a Samsung A17 playing Apple Music and FLAC files and Fiio X1 DAP as a secondary source with FLAC files. When tuned to give preference to Mids as i prefer to hear the voices more than anything else, this comes out as a sweet sounding combination and tracks like Racy Chapmans Fast Car and Massive Attacks Teardrop shine beautifully. The Castor Pros are best listened at about 40% volume and and infact they do actually sound amazing at a high volume for bass heavy tracks such as EDM but for Trance and Rock the cymbals and snare drums sound better at 40%. This pair of iems and the combo sounds like money well spent so far and next i want to try analytical IEMs like the 7Hz. Thanks to the Audio Store for the rushed delivery.
Great purchase... excellent product
Good Product as expected
This is a good dac
Worth every penny! This is not for bassheads as it lacks just a bit on the bass department, but the separation is awesome and the sound stage is also huge. Awesome for gaming as well! (Apex Legends, Arc Raiders, PUBG)
This is the replacement for my purchase of moon drop dsp chu2 which I bought in aug 2025 i don't know how it got damaged from last it stopped working on left side buds and after a few days mic also stopped working and i forgot to claim the warranty for it . So find this spare cable very helpful since I love these IEMS for real Tq AUDIO STORETEAM FOR THE smooth delivery
