Sound is very good and accurate.. Soundstage is also wide and deep.. Like this Bunny...

Overall good quality

WelI i loved the iem Its good for my studyinh and music session go for it iems

Bets budget dac that gives you clear mids and more treble extension... If you are into edm trance symphony orchestra style music... then you will hear better instrument separation...

The cable is soft material so not for on the go will wear and tear... If you are musichead and always hooked then better go with audiocular beam it has cavlar braided cable for good rough n tough life space

Heard a lot of stuff on internet about this dac like hitching or buzzing sound and was bit nervous , but after purchasing I haven't faced any problem with it and I'm fully satisfied with the build and sound quality of the product.

This is one of the best case I have used till today. Definitely beats other cases at this price range. It is much better than the generic cases available on Amazon, Flipkart, etc.
I have recommended this case to my friends who were so impressed on seeing it.

Why?
The quality of music that it is deliveing is Awesome . I was not sure if it is worth investing before buying. But after I tested it , it was phenomenal .
Also I would like to thank The Audio Store , they packaged this box so nicely , it has 4 to 5 level of protection, Also I was not expecting the case , it is cherry on the cake, I was bored of that low quality cases.

Thank You The Audio Store
You're the best

To day it was delivered to me two days in advance to expected delivery. I fixed it to my 4.4mm balanced male of my FiiO FT 7 headphones It's performance is extraordinary. Thank you Ear Audio store for supplying good quality adopter. It's built quality is also very beautiful.

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 😎👍.
