I would like to thank Purecast & Pritam ...I was not sure if this was required. I however noticed it's not a normal dac it's a DAC Amp so it also amplifies sound...it comes in a cool packaging with cover and I am thankful that Audiocular was thoughtful to add a typeC to Type A convertor as I am using this mainly in my Dell laptop. Thanks Audiocular.
Bought the Moondrop Dawn Pro Balanced DAC/AMP recently. Build feels premium with a sleek metal body, swappable 3.5 mm & 4.4 mm outputs, plus handy volume buttons. Noticed extra loudness and a subtle but clear improvement in my IEMs. For the price, totally worth it! 🎶
I used lots of earphones and earbuds, neckband but this IEMs sound is different unbelievable I loved it Thanks 👍🏻
Excellent product. Super premium and sounds balanced.
THE HEADPHONE IS ONE OF THE BEST WHICH DOESN'T NEED ANY TEST BECAUSE ITS THE BEST, THE BLUETOOTH RANGE IS SO LONG THAT ONCE I FORGOT MY MOBILE WHILE GOING TO MARS , NORMAL HEADPHONE WILL DISCONNECT IN THAT RANGE ABOUT 33.9 MILES BUT THEN ALSO THE HEADPHONE DOESN'T DISCONNECTED AND THE MUSIC WAS STILL PLAYING NOW I WAS COMING BACK FROM MARS AND TYPED THE REVEIW WITH MY BARE HANDS 😀
Although termed as Basshead, it's clean and crisp. Bass knows when to punch and when to calm. Upgrading from Juzear Defiant which is itself a great allrounder to its price. Thoroughly enjoying the Martilo. Finally great service by TAS. Looking forward for more.
good build qualityand High quality audio output
Absolutely a beast, had to wait since it was out of stock. This is the best under 3K and probably the best with Mic under 5k.
If you are a beginner audiophile and wanted to invest friendly budget IEM then EarAcoustic STA-Hi End Series IEM is a way to go. The sound is awesome and you can hear every node it contains.
It is the best and clean sounding IEM, perfect for the Beginner.
I love the fact that I can change the nozzle and its a little different sounding, so its two in one.
The cable quality is out of the world no external sound when I touch it.
I can hear so many details clearly. I say please go for this, it is perfect first IEM and the Perfect Upgrade if you had IEM under 2k before
It provides Awesome sound quality go and buy it m
🎧 KZ Castor Pro IEM – Review
🔊 Sound Quality
The KZ Castor Pro delivers clear and detailed sound with excellent separation across lows, mids, and highs. The decent thumping bass is tight and controlled, giving energy to tracks without overwhelming the vocals or instruments. Its super-balanced tuning ensures a natural, enjoyable listening experience suitable for all genres.
🎚 Unique DIP Switch Equalizer
What sets the Castor Pro apart is its DIP switch physical equalizer. With up to 16 different tuning options, it allows listeners to adjust the sound profile on the go—boosting bass, enhancing treble, or keeping it neutral. This feature gives it a level of flexibility rarely seen in IEMs at this price point.
🔇 Noise Isolation
Although it lacks active noise cancellation, the design offers an excellent passive seal. The snug fit ensures that outside noise is effectively blocked, making the listening experience immersive and ensuring ANC doesn’t feel like a missing feature.
🎼 Hi-Res & DAC Performance
For those using Hi-Res lossless audio, pairing the Castor Pro with a DAC is highly recommended. The extra power and clarity from a DAC enhance the already impressive soundstage, detail retrieval, and overall dynamics, making the listening experience truly premium.
💰 Value for Money
At its smart price, the KZ Castor Pro punches well above its weight. It combines detailed sound, punchy bass, balanced tuning, and innovative features—making it a strong choice for both audiophiles on a budget and everyday music lovers.
Have been using these buds for like an year now, they gave me a great time all that while, only recently the cable started getting green and there was an issue with audio drop on even a slight movement (like every earphone ever), but still a great investment for an year.
Got this as my first iem from audio store.. much much more worth than the price.. the bass!!.. my gawddd, it's something which is gonna surprise you.. I got it paired with the moondrop echo a dac.. and trust me, couldn't have asked for anything better.. and the delivery was done to me in kolkata, just within a day.. remarkable job audio store!♥️
Loved the new gear they sound absolutely phenomenal and mind if say the looks and aesthetic of the KZ Castor Pro is underrated for its price, as a newbie I was a little hesitant to jump in this rabbit hole, but it was worth it. Shoutout to The Audio Store to build up my courage, they were very helpful as I was placing my order I fumbled and they responded very positively and helped me correct my mistake. Thank You
