I’ve been spending some serious time with the Hisenior Mega5-EST paired with the FiiO KA17, and honestly, it’s a killer combo. These IEMs have that nice, punchy bass that makes movies feel immersive, but they quickly settle into a clean, neutral side that I really appreciate. The standout moment for me was listening to Tool’s 'Invincible'—the way this setup handles the complex layers and those dual EST drivers capture the 'air' in the track is just amazing. Everything stays perfectly separated, even when the song gets heavy. Huge thanks to Pritaam for the great interaction and for helping me with the selection ; it’s exactly the kind of balanced, high-performance sound I was looking for.

Good product and excellent packing, pouch was also good quality one

The vocals are excellent, it competes with any IEM priced between 1000-1700. I bought it for less than 1000, so definitely go for it for less than 1000. One more thing, if you're a bass lover, you might find it a bit balanced, meaning it's not as bassy, though vocals are more important to me, so that's why I bought it.

This is awesome. You can hear all frequencies individually with standard level. No comparison with earbuds or wireless headphone

Really liked the design and sound . Am new to IEM’s so really not sure what to expect but sound quality was really good and better then my oneplus buds 4. This review is for newbie like me

Clean sound, loud bass. Pretty balanced overall.It still is a bang for the buck.

👌✌️👍

Observed noticeable difference iin audio quality after using this dac, heard reviews complaining about static white noise but I haven't experienced any such issues yet

EarAudio Headphone Replacement Cable - Black /4.4mm is best in quality for my hifiman edition xs headphones with balanced output.

Earacoustic sta hi -end is premium feeling in this price, I bought this product no damage issue and rich into 4days. Sound quality is awesome 👌 ♥️. This is the newly launched iem.

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.

The packaging was very good, properly sealed.
Sound quality: If you are balanced sound signature lover, you would love this earbuds, mids, highs, lows everything is very clear.
No sound distortion even in full volume.
Mic Quality is average and ANC is also average. My main priority was sound quality.
Built quality is also good.

If you are planning to buy your 1st IEM around 1k then you must go with this one no other options are valid against it. And Big thanks to Audio store for quick delivery.

its really good

I’ve been genuinely impressed with this IEM The sound signature feels well-balanced and refined, making it enjoyable across different genres. What stood out most to me is the controlled bass it has enough punch to keep the music engaging It stays tight and clean, which adds depth without sacrificing clarity

Just one cosmic issue which I had is the right shell's rubber has got yellowish I don't know the reason but it is yellowish since I unboxed
