An excellent iem by any means
This in ear monitor deserves all the hype on the hifi blogs and YouTube reviews. I own the first Castor Black version for long time now, I like it a lot and I was very curious how will sound the "upgrade" version Castor Pro Black. For me the Pro in the name is somehow overly pretentious, because the iem have only small, but important changes over the first one. The Pro solved all the main things that was lacking on the first one for me personally-The clarity and resolution on complex fast tracks and the sometimes overly done, slow and muddy bass. All these cons are not existent on the Pro, when the engaging full-bodied timber remains the same. I own also another member of the KZ family, the planar driver PRX, which is double the price of the Castor Pro. Honestly it's only a touch better. When the sound of PRX is very detailed and precise, the resolution is better, it's more linear, the sound signature is not as fun and engaging as the Pro, at times a bit of planar timber is presend. The sound of the Castor Pro on the other side is not linear by any means, it's balanced, V-chaped, organic, big, bold, full, dense, rythmic, bass is deep, brain shaking and excellent contrled, so I have a nice time listening to it. Another iem I own is the Simgot EA500, an 80 euro single dynamic driver with awesome resolution and detail, but borderline clinical. The Castor Pro is opposite on this and I love them both for different reasons, no matter the price difference between. The Pro is so good in my opinion. Just to mention, on specs the Castor Pro seems like an easy to drive iem, but that's not the truth. On my mobile phone or Bluetooth adapter its volume is way too low, and the sound quality is also much lower and muddy. It needs at least a decent dongle dac to be driven properly. I'm using here the Fiio K11. The standard packaging, cable and ear tips are as known usable but nothing special. Actually with that model Im liked for a first time the ear tips, the same old ear tips that
