KZ Castor HiFi Earphone with 2 Dynamic Balanced Armature Drivers, Professional Monitoring, Active Noise Cancelling, Ergonomic Design, and Durable Construction for Exceptional Sound Quality and Immersive Listening Experience in Noisy Environments

The iem is as good as the description it is better than i expect. The adjustable tuning on the iem doesn't make a very big difference, but it works. Sounds is amazing, there is stereo audio, but not sure it can do very well with dolby atmos. I would recommend to buy it, and it fits easily to ear, the ear loop maybe a little bit small if you got big ears like me but it is acceptable. The order is delivered on the estimated delivery day, there is no delay although the update for tracking is not accurate, as my package is delivery and 3 hrs later it said it is out of delivery.

10/10, they arrived ahead of time, very good headphones, 100% recommended for everyday listening.

From south africa ,they are amazing

I ordered it on June 15th and the order arrived at my local distributor after 2 weeks. The delivery was faster than scheduled (1 week less), but it not only had to reach the distributor, but also my house, and that didn't happen due to issues with the company. But that is already external to the KZ company. DATE: Since they notified me that the item was already at the Distributor, they gave me the option to go pick it up and for that you have to contact them (you have to handle it). ARTICLE: -They are wider than I expected (I had to change the pads to smaller ones) -The "switches" operate very well and the change in frequency is noticeable. -I thought it was going to have more bass, but they are very good (comparing it to the basic Kz models). I give it a 9/10 for bass. It meets what was mentioned, maybe I thought it would be Extraordinary, but that was on me. The bass is very good and meets the description. OBJECTS: -1m cable + ears = approximately 1.8m. -White pads, not black.

Tardo casi un mes en llegar, pero el empaque está intacto. Tiene bastantes graves; los agudos están un poco "sucios" pero ya se verá después del "quemado" qué tal suenan.

Excellent product. I recommend the seller. Good quality of the headphone. Excellent sound. Good quality and good purchase.

My earphone came with the right side having some distortion when reaching high frequencies, I've tried everything and nothing works, I won't have the patience to return it.

I love the kz brand but this one sadly wasn’t a good experience with them package completely banged up only one side of the iem worked and i got sent the wrong version

Excellent phone. It has a very neutral equalization, but I reached a comfortable sound with the keys in UUDD. Definitely lacking if you are used to popular headphones, but for my use, who prefers more balanced headphones, it's excellent because you can hear separate instruments and songs with lower-tuned guitars more clearly. I have also used it on my guitar pedalboard and it works well. The cable seems a bit fragile, but the headphones are sturdy. The rubber bands are hard and uncomfortable, but I replaced them with others I already had here, from another brand, and the issue was resolved. I recommend the product!

It's a good headphone, but I wish I had bought the bass version. Now I'm just writing to earn currency, that's it.

Very good for the price, positively surprised me.

Good product but they absolutely do not guarantee anything about arrival within a certain time frame. Being honest, they delayed me for almost 2 months from the first notification about the progress status. Ah, also: the store's support is mediocre, they either wash their hands or simply serve you reluctantly. From there onwards? Well, at least it arrived, and just as it looks in the images. Take care guys, don't be Lavapollos and greetings to the long-named page. -Postage: A1

Arrived perfectly and well-packaged, good quality, approved.

The best headphones I've ever used, both Bluetooth and wired. It came well packaged and arrived on time.

Very very good excellent quality KZ earphones I have several models I want to thank the store and seller congratulations store rating a thousand.

The product matches the advertisement, always with great products. The quality of the earphone is impressive considering the price I paid; it really compensates a lot for this earphone.

It took a total of 37 days to arrive but everything is fine, excellent finishes and material of the earphone feel very good and high quality.

Awesome sound quality, recommended

This is my first experience with large iems. I bought both kz castor and kz pr1. I am impressed with the sound quality of both. I have a slight preference for the pr1 as i feel more of the sub bass. With both i get a very rich and pleasant sound without the need for eq. The only problem i had is that the silicone tips provided are too small. I had to get bigger ones from other samsung earphones that came with smartphones. Now i have ordered the memory foam tips, we will see how i get on.

The package never arrived, more than 45 days have passed and it never arrived.

I felt a bit late until it arrived.

The headphones are very good and comfortable, especially the KZ Castor Bass Edition. If you dare to try them, I encourage you for the bass edition. The shipment was not delayed but on time. The quality is very good for its price.

Good sound and they feel of good quality.

The product matches the description. It is original. The only problem, at least in shipping to Mexico, is that this seller ships through PostNL which in turn passes the package through the Mexican post office, which takes more than a month to arrive.

they sound good. good packaging though I wish there was a bag to carry them around

Cheap, good sound, switch gimmick, cute connector, sturdy.

Shit never arrived

The headphones did not arrive, I requested a refund and it has not been processed, supposedly they should have arrived since May.

super super super good watch quality price. good watch no complaints recommended from Mexico Mexico.

The quality, at first glance, is impressive; they seem as if they cost four times more. The audio quality is also outstanding: the bass is present, but it seems necessary to use an external DAC as I connect them directly to the 3.5 mm jack of a Poco F5 and an iPad Mini 4. In songs that I know have a very deep and massive bass, it cannot play; it even sounds quieter than in others that don't have as much bass. I think this is because they need a DAC.

Excellent phone. I got the version with Bass boost. I have a KZ EDX Pro X and I noticed the difference in power; this one is more powerful, comfortable, and with better bass (obviously). Now regarding the other frequencies, I found them equivalent (to those of a regular person who just wants to listen to music and play a game).

Excellent earphones. Sound quality is on par with full-size hyperx cloud alpha headphones. Very nice to look at visually.

Excellent product I recommend the seller Good quality They sound excellent Good packaging.

The best recommended 100 headphones have very soft audio, with many sharp ones but balanced.

Very good phone

Arrived quickly and worked perfectly.

The sound quality will please even demanding users. The whole frequency band. They sound very decent, i usually use marshall major 2 and akg samsung buds 2 pro. They sound at the level. I recommend.

Order received at advertised. Quality sound

It was an extremely rewarding experience, without a doubt. The obtained result exceeded expectations, demonstrating the value of the effort.

I have both models and both are excellent options for the price. I tried them both with a DAC and with the cellphone. The Harman Edition has better instrumental separation, the voices and harmonies sound clearer, and the amount of detail is greater. Stand out in acoustic, jazz, or instrumental. The high frequencies predominate more, although they can be adjusted if they are bothersome. Its performance improves noticeably when used with a DAC. The Bass Edition is perfect for electronics, pop, or reggaeton, that is, the most fun and energetic music that needs more stickiness. The mid and high frequencies are still present, but it doesn't reach the detail level of Harman. It sounds very good connected only to the cell phone.

It took longer to arrive.

This is my first item that i bought from aliexpress, and the item flew all the ways to malaysia. So far i have been very happy with this kz castor bass iem product. Thought their are some hiccup during delivery which took longer then expected to reach to me, but it is all worth it. Kz castor bass truly blew my mind, the sound on the low and mid are exquisite, even the sound of drum snare are very crisp. I would really recommend this earphone for someone who are new in audiophile journey.

KZ is undoubtedly the best in the segment, 1000% quality and price, a high-quality product, excellent sound.

Excellent headphones. There are many graves, for those who like to listen to Hip Hop, it is the most recommended.

for the price, super

I spent, I liked it very much, very good, very good, very interesting, very good, very good, very good, very good. Incredible, I liked it

They sound good

All good, as always.

EXCELLENT AUDIFONES, VERY GOOD RELATION, COSTO BENEFICIUM AND COSTRUCTION MATERIALS. It took me some time to arrive due to customs issues, outside of that everything was correct.

work. everything came whole

They are of good quality, the audio for their price is incredible, they arrived on time. Kz is excellent for the quality it offers.

Very good headphones, the only bad thing is that the shipping took more than a month.

Great headphones

They work great, I had already had the KZ ZVX but these sound better, the most notable thing is the increase in the bass.

Very good quality, I really liked it for both music and gaming use, very good quality! !

Fully meets my expectations, they are super comfortable and of very good quality, highly recommended.

Quality on another level

just like the advertisement. I recommend it

Fabulous headphones, they are very much worth it, they feel of excellent quality and the audio is great.

It takes too long

The headphones do not have a mother, they are very pretty and sound wonderful once you find the right adjustment for your ear, you will not want to stop hearing them. I don't regret this purchase, it was the best decision of 2025 and I would buy them again. The sound quality is good.

not too bad..

It arrived too late. almost 15 days more delay. But anyway, issues with parcels and customs. From there on out, the package arrived excellent. What else can I ask for from these in-ears? They are simply the best I have ever purchased, for the price they are undoubtedly splendid, highly recommended. I recommend equalizing them with the small equalizer that comes integrated since I feel it is too low-end, but without a doubt, I recommend them. Do not hesitate to buy them from Mexico. They are the best. It doesn't ask much from Shure.

It took a long time to arrive, honestly I won't order from the official store again, almost 2 months of waiting, it's not worth it.

just what I wanted, a balanced sound and good sound quality, I bought the Harman version and they do not disappoint, as a reference, the voices sound less than some ZSN Pro X and they also sound with less bass, but for the better.

It arrived on the estimated date, it is a good product, but I do not recommend it too much to use on the street since it has a form of sound to enjoy without so much noise.

Very good audio quality, they are heavy and feel of good quality, the bass reinforcement is noticeable, apart from that you can configure them to your personal preference, highly recommended and even more so for the price.

Actually, I suppose that these headphones already have enough reputation for their quality. All I have left is to recommend to those people who do not have a port jack 3.5 on their phone is to buy a quality USB C adapter that helps reduce white noise, beep, and interference.

So far after half a day of trying it, it's actually really nice without forgetting this price point, i mean for an "ultra budget" it's super good, don't forget to suit the switches to your preference, i found the uudd is best for gaming and music too. Delivered after ~10 days which is the minimum expected date for delivery to where i am, so fast delivery, good item status, and the product is good, which is everything you'd want.

Great

Very good product. Sound could be improved with wavelet app in android, see kz castor autoeq with the proper combination off-off-on-on or whatever it is your set up

Everything arrived correctly, well packaged. It came with some extra plugs in the box. In terms of quality, I'm quite clueless about audio. My previous headphones were an AKG that came with the S10 (which I already thought was good). Oh man, it's bizarre how good this castor is, it has a really great gift, the impression it gives is that in music the instruments are separated like in a live band and with it I listen to instruments and things that I've never heard before with other headphones and earbuds I've had. I played some games with it and you can really tell where the enemy is, very good indeed. And its microphone doesn't disappoint, very similar to the phone's own microphone. I recommend the purchase and the store.

Top quality definitely worth it!

It is recommended to use Currier if shipments are to Ecuador, otherwise there is a high probability they will not arrive.

The best for playing Warzone

Very happy with these iem for the price. Sounds very good and a good combo with the btr17. Very recommended

Great phone, metal finish, very beautiful, comes with a mini manual showing the position of the buttons to change the audio style.

Very good phone, better than expected. For use as music, it will be a good option considering the cost and benefit. I recommend

As always, these excellent headphones have the best quality, closed prices, I highly recommend being the best.

They are of good quality, the audio for their price is incredible, they arrived on time. Kz is excellent for the quality it offers.

Delivery ok, well packaged and protected. Well-made earphones, all made of metal, and very good sound quality.

The phone is great, arrived very quickly.

I have some Huawei Freebuds Pro 2 and these sound much better! !! I recommend the ones without a microphone.

Very good, excellent guitar pickup, crystal clear sound.

Top

Good sound quality, without any failures.

Headphones with excellent audio quality, excellent detail and instrument separation. I use it with keys 1 and 2 connected. Every penny is worth it!

Excellent product. It was what I imagined. I will buy another model later.

Top dos Top

The phone will be sold, so I don't have real internal photos of the product. It came well packaged with bubble wrap, everything is fine. I have tested the KZ Castor Bass before and it is one of the most fun headphones because with the tuning keys you can adjust the sound to your liking. It has powerful bass with correct midrange without presenting sibilance, and can even be reduced in the keys.

The best purchase I've made, the headphones are very good.

Good good good good good good good good good good good good good good good good good good good good.

Very fast shipping to serbia and good quality of product for cheap price i was surprised with quality of product and quality of sound.

It took a little while but everything arrived in order, well-packaged. Very good headphones, clean sound and great quality. They don't disappoint, highly recommended!

The order arrived on the estimated date, everything is correct, it is just as described. I like the sound.

Balanced and detailed sound: The KZ EDX Lite headphones have a new generation of internal magnetic dynamic drivers. Achieved a lower distortion and optimized performance of three frequencies to provide maximum detailed media and present more sound details. Thanks to the efforts of the KZ acoustic team, the KZ EDX Lite headphones have acoustic metrics on par with other so-called flagship dynamic driver headphones, offering exceptional frequency response and minimal distortion across the entire range, ensuring a completely natural and smooth tone. 【Dynamic Super Linear Driver】 The KZ EDX Lite iem headphones use an ultra-fine internal magnetic dynamic driver, which adopts a hidden internal soldering structure and an internal magnetic design, and the magnet height is greatly improved, and the bass performance is better. The driver has been updated with a new internal cavity, and the formant position control.

I have received more, however, it was very slow, almost a month.

It took a little while to arrive, but the wait was well worth it, excellent product

Better phone I've ever had.

Incredible sound quality for a headphone in this price range. Well-balanced and pleasant sound. Very good build quality with a beautiful finish.

They arrived a little late, but it was worth it, they are. Very good for bassists and general use to live play, the bass can be heard very strongly in the figure 0011.

Excellent bass, midrange, and treble with balanced bass. Ideal for those who have Type C (PIN) cables and also for those who lost the adjustment pin - the chip pin worked perfectly. Great headphones for gaming and listening to music.

Does not include foam ear tip as it mentioned in the item description

Excellent quality. It took a long time to arrive but the wait was worth it. Good quality in material and sound, highly recommended and excellent price.

Everything is okay, everythingis okay,

Everything is okay, everythingis okay,

Very good product, arrived well packaged! Excellent quality, I highly recommend this headphone, great sound quality.

you need to immediately order other ear pads for these headphones

God

The audio quality of the headphones is excellent for the cost-benefit ratio. However, if yours comes defective, don't waste time asking for a refund — the seller will try to stall you as much as possible, and AliExpress simply doesn't understand that the product has an issue. In the end, you will only lose money.

They arrived correctly packaged and sealed. I used them a little but the finishes and material seem of good quality, the sound is very good but they need to be properly equalized. Very satisfied with my purchase.

I am impressed. I have an AirPods Pro and this is my first wired IEM, the quality is beyond belief. The bass is very clear and well-defined, and when testing with some songs, I haven't felt any popping so far. The delivery took longer than expected, but it arrived without any issues. In total, it was 20 days. I recommend the product and the store.

Excellent phone, good construction, both for gaming and stage performance, the phone is great.

Excellent product, I recommend the seller.

Pretty good

Very good phone, excellent quality! Very good phone, excellent quality!

Gooddddd
