- **Elegant Design:** The design is sleek and modern, with a well-thought-out layout that includes a large, high-resolution touchscreen, physical buttons, and a volume wheel.
- **Portability:** Despite its robust build, the R8 II is relatively portable and can be easily carried in a bag or large pocket.
Weaknesses:
- **Weight:** The premium materials contribute to a heavier device, which may not be ideal for users seeking ultra-portability.

I have been using this sweet device for a month & let me tell you, it is eye-opening. The learning curve has been rather steep for me since this this is my first real DAC. This is like learning to drive for the first time but you only have a V12 Ferrari. This flagship has 2 types of Amplifiers, A & AB. I have left it on A because it sounds most natural. This device is heavy, almost twice as heavy as a high end mobile, so it is not something ultra-portable. The form factor of this is like a big mobile & twice as thick. What is amazing is that for the features & quality it has, should not be possible in such a form factor. It should have been the size of a big CD player of old, but it is tiny for its features. That tells me technology has come a LOOONG way for the audiophile from the days of Vinyl & tape, then CD, now DAC. I play it via computers, Bluetooth receivers & standalone through Blessing 3 IEM. The journey of the modern audiophile has begun, for me. I still have CD & Vinyl & tapes of old & new artists. The Hiby R8 II adds yet another dimension to this.
We're thrilled to hear that you are enjoying your HiBy R8 II Hi-End Android Digital Audio Player and that it has been a game-changing experience for you. We understand that the learning curve may have been steep, especially as a first-time DAC user, but we're glad you were able to navigate through it. The A amplifier indeed offers a more natural sound, and we're glad you found your preference.
Thank you for acknowledging the quality and features of our flagship device, and we're pleased that it has exceeded your expectations. Technology has certainly come a long way, and we're proud to be at the forefront of providing top-notch audio experiences. We hope you continue to enjoy your HiBy R8 II and explore the endless possibilities it offers.
Happy listening!

🎧 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

Amzing product

Love the way it sounds rich in every range perfect for beginners but if you're not a bass head go for non bass varient.

This is my first ever IEM that I purchased after research of couple of months. And I can say that this was a good decision on my end. Cable is good. Buds look stylish. Comes with a small carry pouch and 6 pairs of ear tips. Sound quality is awesome. Love the instrument separation. Customisable EQ gives them versatility. You can actually experience how other IEM sound just be playing around with the EQ.

Actually, l'm new to this IEM world. Such an amazing product. If you are new to iem just as me, I would highly recommend his product to try out. The OG. There are 16 types of tuning options to play around and explore your favourite music in a new way and the build quality is also pretty good. Overall a nice product 👍.

Good sound

5/5 Mids and Highs
5/5 Well balanced Bass, doesn't overpower the music
5/5 Design look premium and classy
They are quiet heavy and huge

Its my first time buying an iem and it sounds sooo good the design is good the wire can be improve, the bass is somewhat missing and the app has some glitches regarding equalizer. Otherwise this iem is better than my tws. I really like it.
