Review: Best Budget IEM Under ₹2,500 - The KZ Castor Pro is one of the best budget IEMs currently available. Its dual dynamic driver setup delivers impressive sound quality with deep, punchy bass, clear vocals, and detailed treble. The biggest highlight is the 4-switch tuning system, which allows users to customize the sound signature according to their preferences, making it suitable for various music genres. Build quality feels premium for the price, with a sturdy metal-resin shell and a comfortable ergonomic fit for extended listening sessions. Sound separation and imaging are excellent, making the Castor Pro a solid choice not only for music but also for gaming and multimedia consumption. Reviews consistently praise its value-for-money proposition and highly detailed sound presentation. On the downside, the default tuning may feel slightly bright for some listeners, and achieving the best sound often requires experimenting with the tuning switches. The included cable is functional but not exceptional. Some users have also reported occasional microphone quality issues with the mic version.
Review: 🎧 KZ Castor Pro Review (Compared with Oppo Enco Air 3 Pro or IEM vs TWS) - 🎧 KZ Castor Pro Review (Compared with Oppo Enco Air 3 Pro) I had been using the Oppo Enco Air 3 Pro since February 2024 and absolutely loved their sound. Unfortunately, I lost them a couple of months ago. Since they’re currently unavailable in India and the Oppo Enco Air 4 Pro are still far from release in India, I started looking for alternatives — that’s when I came across the KZ Castor Pro. Honestly, I doubted that any IEM under ₹2,000 could come close to the Enco Air 3 Pro, which costs more than double. Still, curiosity won, and I ordered them. Out of the box, they didn’t sound very open or spacious — just like any regular earphone at this price when tested on my laptop. So, I decided to pair them with a DAC (Audiocular Spark), used Wavelet with DDUU DDUU tuning switches and a U-shaped EQ, set Dolby Atmos to Movie mode, and enabled Hi-Res Lossless on Apple Music. That’s when the magic happened. The soundstage opened up, the instruments came alive, and suddenly they started outperforming my Oppo Enco Air 3 Pro. The highs are detailed and sparkly yet smooth — never harsh, sibilant, or shouty. They carry just the right amount of brilliance, giving instruments that lively shimmer without fatigue. The mids are pristine, especially the guitar strumming — it sounds crisp and clean. Vocals have an airy, reverberant character that makes them feel spacious and natural. Instrument separation is excellent — you can easily identify sounds coming from different directions and depths. The bass is tight, punchy, and rich, with good sub-bass rumble and satisfying kickdrums. However, despite being labeled the “Improved Bass” version, the Castor Pro isn’t for bassheads. If you prefer that boomy, club-style bass found in TWS from brands like OnePlus or Realme, this might feel a bit restrained. The bass here focuses more on detail than quantity. The soundstage is similar in width to the Enco Air 3 Pro — moderately wide but with slightly more airiness and openness. Imaging is excellent too; you can easily pinpoint footsteps while gaming. The mic quality performs very well indoors, better than most TWS under ₹5,000. It lacks noise reduction, though, so outdoor performance may not be ideal. I’m giving them ⭐ 4 out of 5 stars, mainly because of the cable quality, which feels cheap (though it gets the job done), and the included eartips didn’t fit my ears properly. I’m currently using Sennheiser CX TWS eartips, which improved both fit and sound. Overall, if you’re looking for a replacement for the Oppo Enco Air 3 Pro, the KZ Castor Pro delivers even better sound quality at a lower price, especially when paired with a DAC and proper tuning.
