KZ Castor Pro - a superb IEM in the budget with perfect blend of quality, design and sound signature.It comes with a mic and the 4 bands eq setting for each earbud to customise your listening experience.The bass , vocals and treble each can be adjusted as per the user's choice.Pros - 3.5 mm jack for overall compatibility , good amount of bass and Equalizer settings on earbuds.Cons - wire length is too short and feels quite cheap.Overall a good investment for beginners who wants to use IEMs.

This iem has perfect balanced sound and pretty much a jack of all trades product. However the bass is a little shallow , though the pristine sound quality kind of makes up for it.Only one thing to note for new buyers , if you don't have a setup that gives a clean noiseless output or a cheap and bad dac which is not at least 24-bit supporting , then these headphones will sound really really terrible. You will need a good driver and clean signal to get the proper sound quality that these headphones produce.Overall these are a good buy and 9/10 chances you will not be disappointed.Some pros:-1. Comfortable to wear2. Design is really interesting3. Mic works well4. Easy to use , bonus if you know your way around Equalizer settings.5. Fits perfectly for the most part.

Guyzziees, my first new IEM arrived :-KZ CASTOR PRO IMPROVED BASS editionGot this for 1850 from Amazon Paired with AUDIOCULAR D15 ALC5686 DAC, This is my first DAC & IEM, My first impressions on this:- Premium looking Punchy bass Shiny glossy finish Great packaging even though it's enviornment friendly Everything this working awesome Listened to my favourite songs, it was like heaven, Mic functionsvery much great! it's too much comfortable, this IEMS definitely achive you Spritual ENLIGHTENMENT Too clear voice, vocals, instrumental music, Mazaa aa gaya....!!One should definitely consider buying this without any hesitation and problems, JUST GO FOR IT!!if you read this long

It's more than what I had expected, the sound quality is just too good to be true.First of all the lows are amazing and with the tweaking u can adjust it as per your likings, the vocals and mids are clear and u can literally separate each and every instrument. Even at high volumes the quality isn't distorted. It also works great with a 3.5mm to type converter no loss or anything. I even used these for FPS games and the sound the footsteps and everything is pinpoint. But the wire being a bit small it would be better to have a male to female 3.5mm extender. For long use I would definetlt recommend these. But yes u will have to be a bit careful with the wire it's a bit delicate. Other then that the bass is good i don't think u will be disappointed it's not too powerful it's not too less it's just perfect doesn't overpower or anything. And I would suggest you to go with the microphone version except that, very easy to use, connectivity is great since it's wired no latency of whatsoever. If this is your first iem I would suggest you to just go for it don't think just buy it.

I purchased the KZ Castor Pro primarily for use with my MacBook Air (M4) and as a budget-friendly alternative to my older premium headphones (Airpods Pro 2(music, movies, meetings) and Hyperx cloud alpha(Gaming)). After using it for a few days, I’m impressed with its performance for the price point. Sound Quality:The audio performance is excellent. The bass response is tight and punchy without overpowering the mids, and the treble is crisp yet smooth, avoiding any harshness. It works well for a variety of genres, from EDM to acoustic tracks. Instrument separation is decent, and the overall soundstage feels slightly wider than most wired IEMs in this price range.Build Quality & Comfort:The build feels sturdy enough for daily use, and the ear tips provide a good seal for passive noise isolation. The fit is comfortable even during extended listening sessions, but as my ears are small, the outer part rubs on my ear outer muscle, which pains after 1-2 hr continuous use, though the cable feels slightly thin and could have been more premium.Compatibility & Features:On macOS, the earphones are recognized as a standard wired headset. If you’re expecting Apple’s Spatial Audio feature to work, keep in mind that it’s exclusive to AirPods (Pro/Max/3rd Gen) and some Beats models. You can still achieve a surround-like effect on the MacBook using third-party apps like Boom 3D or eqMac, but native Spatial Audio is not supported.Pros:Excellent audio quality with balanced tuning, Comfortable fit for long sessions, Great value for moneyCons:No native support for Apple Spatial AudioCable could have been better in terms of thickness and flexibility Final Verdict:The KZ Castor Pro is a fantastic option if you’re looking for wired IEMs with great sound quality on a budget. While it lacks support for Apple’s ecosystem features like Spatial Audio, it delivers where it matters most: clear, enjoyable sound. Highly recommended for music lovers who don’t need wireless or Apple-specific features.Settings: All Down.
