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..
Gud
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.
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
Excellent product. Has improved the performance of my Sony xm5 by leaps and bounds on the Apple products. Also one pairing is good enough for all of them.
First off great speed of delivery from The Audio Store. Literally got them in like 2 days. Genuine quality product.
I upgraded from my Moondrop Harmons, was pairing them with the ibasso dx180. Readup about the Monarch Mark4 and went for them as they had a similar sound signature that I like not too clinical, just the right amount of bass and warm lush vocals. The ability to switch between two sound modes with the built in switch sweetened the deal for me. Sound is amazing built is great. Could hear clear sound separation, clear instrument separation and a much tighter bass compared to the Moondrop Harmons.
What I didn’t like was the case that comes with it and probably the cable they seem to be thick and bland in design against the beautiful aluminium iem case. The fit of the iems was also not an issue although bigger than most fit my ears alright. Provided ear tips are great.
Regret getting them because now I want to unlock their true potential by upgrading my dap :D
First of all I want to thanks TheAudioStore for customer care, well packaging and prompt delivery. Regarding the sound and comfort, I could not gone through all details since I got this only yesterday. Though it is little bulky, I am not feeling much uncomfortable while wiring it. As reviewer says that the quatio is bass forwarded profile maintaining its clarity across all frequency range.
My second iem after the Tangzu wan'er sg 2, and compared to the smooth and vocal tuning on that this is the IEM that's got the energy and the fun tuning going for it. The package feels a bit lacking but the sound makes up for it a lot. Go for this if you want pure sound bliss.
packing, The IEM’s delivery all amazing. loved it
Thank you Sir/ma’am for this product worth every penny on ears
