Excellent delivery experience, it was a gift wrap.
My first time ordering from the audio store, really impressed.
And the device is marvelous.

Comfortable & Excellent quality. As per heard, i was looking adaptor for my Tangzu Warner sg wired IEM. This KZ AE01 fulfilled my needs for bluetooth adaptor. Music sound quality is good. Fitting is also fine. Call quality is little bit low.
Otherwise ok for bluetooth conversion of IEM.

It surely enhances all parameters of sound quality like stereo effects, vocals, all frequencies, soundstage and imaging.

I am saying it based on a week experience with multiple basic IEM like EPZ Q1 pro, Simgot EW 300 DSP, Moondrop chu 2 with hiby R4 DAP.

Highly recommended to upgrade existing budget IEM.

Although Cable is thick, its very much flexible and handy. No issues while handling and carrying it because of its thickness.

It's thickness enhances overall look of IEM.

Super Bass and ultra clear vocals in
affordable price..

REVIEW AFTER ONE MONTH DAILY USE

Initially, my set up was 'Samsung S 23 ultra + Simgot ew 300 DSP' for daily music listening hobby.

While upgrading from this set up, 1st I bought HIBy R4 DAP, used it for 10 days with same IEM and then decided to go for another big upgrade for iem. After trying existing iem on multiple phones, surprisingly I observed that 'Hiby R4 DAP' is superior even on high-end phones in terms of sound quality.

While upgrading IEM, I kept below criteria and told Mr. Pritam the same.

1. IEM with crystal clear sound with all details & balanced sound.
2. Ultra wide Soundstage & clear imaging
3. Clear stereo effect
4. It should separate Instruments sounds when there are multiple instruments in song/music.
5. It should handle bass heavy songs without compromising vocals & trebles.
6. Comfortable for long hours.

Now after using it more for one month, I can say that -THIS IEM HAS FULLFIELD EACH REQUIREMENT & ASPECT OF SOUND QUALITY.

Only downside I felt that Packaging and Case should be premium in this price tag.

EXPERIENCE WITH AUDIO STORE -

I had some options for IEM in my mind based on previous listening sessions at audio store office as well as youtube & web reviews.

I recently visited audio store office two times for some other product requirement, All those previous options, I tested all of them again. I found that Mr. Pritam's suggestion to buy MK3 over other IEMs is worthy.

Thanks a million Mr. Pritam for always helping & guiding before taking any major purchase.

Superb Cable!
Works well with Zero 2
Value for money product

I am very thank full

I really like the quality of the product not only that I really like your store Too
I want to work with your company as a employee please let me know if there is any openings

I'm an IEM guy and after a long time I've been really impressed with a speaker. And at such a fantastic price point. The sound is so smooth, you can listen to it for hours without feeling fatigued, and most important thing for me was, it sounds just as good on low volume when you want to listen to something in the background, but have guests and are going to talk over it.

Incredible separation. Very good stage, fills a 10x10 area nicely (with windows closed). Bigger area and you might feel the need for two of them (heh). Excellent details on both the bass and treble. This is very much a fun sounding speaker. Female vocals are slightly more recessed than the male ones, but the separation will ensure that they come through nicely nonetheless. Drums on this thing are just a blast (literally!). Strings are so melodious.

Last but not the least, looks are killer. Everyone notices it instantly (although it blends very well with the home decor) and asks what it is. Pick it up. You cannot go wrong.

This headphone needs some time to be given. I have sold these 2 times and bought again and now they are permanent in my collection. I now understand them and you need a seriously good amplification system and then they are much more of a lushfull/true/audiophile sound that surpasses almost all headphones under Rs. 50000 easily (including Hifimans).

It has a satisfying amount of bass
Crispy treble region and clean sound signature
Comfortable fit
Pair it with a good DAC and see the magic happen!!
Must have IEM!!

Great product , comfortable for median and large size ears, bass is mid-level, nice gift packing

Comfortable fit, perfect for long listening sessions.

It's affordable yet can punch above 5 times the cost bracket. The planar soundstage is massive. Separation is great. I love the red filter. Jazz, blues, and instrumental sounds mind-blowing. Worth every penny
