Awesome product 😎
Great tips
Very comfortable with a good seal. No more worry about wax entering the vents. Quality is excellent
I was wondering, whether to buys Fosi Audio ZD3 for my MC351 Amp/ FiiO BTR-15 for my Sennheiser IE200, hmm have to purchase two devices, still no Bluetooth receiver with LDAC/Apt-x lossless).. Here I got this as a hybrid. 1. Works as desktop DAC connected with PC or Bluetooth Receiver for home/on-the go during travelling, small, cute and compact, here is the deal breaker.. I found to replace all three devices (1. ZD3, 2. Fiio BTR-15 3. Fiio BR-13) all in once small DAC... so why not to purchase my dear audiophiles, testing is in progress, volume feels little low, still using 3.5 mm, not had chance to check 4.4 mm female port yet, where it shows true colors, waiting for 4.4 mm cable for my IEM.. will update my review soon.. Boom Boom: How to unlock volume from 15 to 30 Steps to Maximize Volume & Clarity.
--------------------------------------------------------------------------------
To fix the low volume while maintaining the high audio detail of the dual CS43198 DACs, follow these steps:
Unlock the Volume:
On the HiBy W4 screen, go to Settings > About.
Tap the firmware version number (e.g., "HiBy W4 1.00") 5 times rapidly to enable Developer Options.
Go to the new Developer Options menu and turn Volume Lock to "OFF". This allows the volume to reach its true maximum (30/30).
Set to High Gain: Enter the Audio Settings menu on the W4 and change the Gain setting to High. This increases the output voltage, providing a stronger signal for the MC351's RCA inputs.
Manual Line Out: Since there is no fixed Line Out, manually set the HiBy W4 volume to 27 or 28 out of 30. This mimics a standard 2V line-level signal without introducing digital clipping. Enjoy.. :D

This iem was recommended to me by youtuber Rohitagni Mukherjee and indeed it was a good recommendation.
The KZ EDX Pro offers a clean V-shaped sound signature with punchy sub-bass and energetic treble. Bass has good extension without muddying the mids, and vocals remain clear though slightly recessed. Treble adds sparkle but can get mildly sharp on bright tracks.
Instrument separation and soundstage are impressive for a single dynamic driver at this price point. Solid build, detachable cable, and comfortable fit make it a great entry-level IEM for detailed listening on a budget.
The included EarAudio carry case is compact and sturdy, offering decent protection for daily use. The zipper feels smooth, and it easily fits the IEMs without forcing the cable. A practical addition that helps with portability and storage.
I got the AUDIOCULAR SPARK Hi-Res Portable DAC Dongle (CX31993 + MAX Amp), and it’s totally worth every rupee 💸. At first, I thought using a DAC was unnecessary since my phone already has a headphone jack, but I was wrong 🤔. The moment I plugged it in, the sound quality jumped by at least 50%—louder, clearer, with way more detail in background instruments and vocals 🎶. It’s a one-time investment that seriously upgrades your listening experience, especially with budget IEMs like my KZ Caster Pro 🎧. If you’re into good sound and have the budget, get it—you won’t regret it. Better than expected. Thanks, me later 😎👍.
Love the iems, they are my first iems and my god these things beat everything I've ever used.
Does feel a little more on a heavier side, or maybe I'm not getting a hang of em just yet. As for this price it does not disappoint, for the sound quality ethics its 3.7/5. You guys Can go for Vader Pro series not sure if you appreciate +1/2 score(4.2/5), they does sound better.
Jus a little guide for you all if you're considering KZ under 3k range, Castor pro < Duonic Enhanced < Vader 3 pro Enhanced.
Didn't thought I would be this spacious, Zip feels sturdy let the time tell. Would recommend as to now.
Here is an IEM which bifercates sound distinctively in all 3 levels - the Highs, Mids and Lows that produces such a crisp and clear representation of your favourite music. Even if V signature is not your thing this will change that. People who prefer HM reference would want to switch after giving these a try. Top it up with EARgonomic metal shells that KZ is known for creates a perfect seal even with stock eartips. So, if you own a Castor Pro, Zsn Pro 2 or Trio and love them then this totally upper tier.
Audiostore did a good job in delivering these, BEFORE TIME.
So, yeah loved the overall experience.
Tnx
The most comfortable IEMs I have ever used. Resolution, soundstage, and instrument separation — all in one package — make it a one-of-a-kind experience. Such a great all-rounder. If you’re considering buying these, don’t think twice — you won’t regret it. Heartfelt thanks to Mr. Pritam for supporting and endorsing the decision.
Very good service
