KZ Castor in Ear Monitor Headphones with Mic, HiFi Improved Bass Earphone Sound Tunable Noise Isolating IEMs, Dual-Dynamic Driver Wired Earbuds, 2PIN-C Detachable Cable for Singers Musicians

I was looking for a set of entry level iems and these do not disappoint. The gimmick being the switches. I like how there is versatility to tuning with the switches built in if you dont want to use a dedicated app. I still used these to this day and they have some bass that isn't overbearing. Cord length wise it is decent. The ease of use is simple. Quality is top notch. These dont have noise cancelation but the ear buds do block out some noise. I plan to buy more of these.

In a word "detail", these have way more detail than my Pixel Buds (which I like). The stereo image is good. The sound quality is good. These things seem to have a balanced frequency response when I listen to music. Bright vocals. Good low end without needing to turn up the volume to 100%. Yet when I did turn it up they got loud and are punchy from low to high. When I listened to pink noise, the upper mid range is louder than the other frequencies. Not a deal breaker at all. Normally I use Comply foam tips with earbuds. These were good with the large tips that were in the box. So I listened to these on my Pixel 8 Pro via a USB adapter. I listened to Justin Timberlake's new song "Drown". I also listened to some songs from BEP "Energy Never Dies". I paid $17 for these! The quality to value is massive (quality really good / ultra low price). I won't say these KZ DQS in ear monitors/ear buds are perfect. But I will say they are really good and enjoyable. I'm glad I bought them. I will buy more (one in my backpack, one at work, ane at home. Update - March 8, 2024 I put some unused Comply foam tips on them and they really helped to reduce noise around me. But my Comply tips are large and aren't as comfortable as the stock tips that came with KZ DQS. I plugged them into my laptop, played Apple Music's Hi-Rez audio and I am still content. In fact I happen to have some $99 Sennheiser HD 280 Pro headphones where I am at right now, AND... the KZ DQS are more enjoyable. Dare I say, sound way better? Um, ya. Ya they do. Probably cuz I don't have an external DAC and headphones amp for the Sennheiser to make it a fair comparison. The KZ DQS gets plenty loud and would blow up my ears if they got louder. I will to remember to add updates to this review over time.

I will admit , I had my doubts about these headphones based upon the price, however, they are worth 10x the money you pay for them. I bought these so that I can use these thru my effects pedal to play my guitar or work on mixing tracks while my 5 year old sleeps. I have tried many different headphones for this purpose and they all fell short in some aspect. Not loud enough, couldn't handle distortion well, heavy bass notes on clean channels were distorted, or high notes would freak out. These headphones take everything I throw at it and begs for more. Sub bass response is phenomenal, highs are crisp. When most headphones freak out on sub bass frequencies and cant still produce good mids and highs. these headphones laugh at them. I only wish there was a Bluetooth version of these for my EDC. If your reading this to make an opinion, stop questioning and just buy the things, you wont regret it.. but go ahead and buy the 10' extension, your gonna need it.

When i opened the package, i wasn't expecting much judging by the packaging, but i was pleasantly surprised. Shocked in fact! These sound better than my Floyd Rose in-ear monitors (compared them side by side). The clarity is not what i expected from this price point. crystal clear and clean highs, tight and balanced bass. There are 4 small switches on each ear piece that lets you boost or cut lows, highs, and to an extent the mid response. I chose an overall flat response which was satisfying to listen to, then i tried bass boost 1 setting, nice subtle but effective low curve boost. not overpowering. When i finally settled down for an extended listening period, they seem to disappear sonically in a way where you almost can't tell you're wearing them or where the sound is coming from. That illusion is consistent with high quality headphones and speaker systems. As sound engineers, this is what we strive for in our designs. Before you spend big bucks on custom in ear monitors, give these a try. Warning, Technical stuff: Passive and tuneable in-ear monitors, so there's obviously no active noise cancelling, but when properly fitted using one of the 3 different size silicone ear fittings, they block out much of the ambient room noise. Mind the placement in your ear. the part that goes into the ear canal is in the down most position and the stiff formed part of the wire wraps around your ear and exits around the back of your head. this ensures an non slip fit. All things considered like pricing, fit, and tuning controls, this is a lot of bang for the buck. I give this a 9 out of 10 rating

The sound in these are phenomenal! Great price and quality.

Got a pair on a whim a while back. I've been a working musician for years and although these are chinese and cheap, they sound good and fit well which is unbelievable to say the least.

Heel zuiver geluid, bij lage impedantie - geen extra versterker nodig. Bas wordt niet overdreven, dus goed in oor passen is belangrijk. De draad gaat "over ear", waardoor de oortjes goed blijven zitten

Great earbuds, especially at the pricepoint, however id appreciate a little better bass and a little better top end but thats me being picky 😂

Qualitativamente buone Non cadono mai!!

Yes I liked it it have a very good bass and with very nice noise cancellation

I was blown away by the KZ DQS. The sound quality is incredible for the price-crystal clear vocals, detailed highs, and tight, punchy bass. They're built like a tank with a great detachable cable and are super comfortable. For anyone looking to upgrade from basic earbuds, this is the perfect choice. Five stars, easily one of the best purchases I've made!
