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

Very good headphones been using for a month now. Sound quality is good and the build itself is solid. They’re also very cheap and cost little to nothing. The part that goes in your ear has started to hurt my left but that’s a personal thing with my ear. The cord length could be longer but they’re easy to take on and off so no biggy. THE ONLY THING is that the right earbud disconnects due to faulty wire connection. If the ear strap isn’t around my ear they disconnect. The gold rod in the wire has bent a bit and doesn’t work without the strap. Again no big problem but that’s all I got to say. Very good stuff for such a low price.

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, 2024I 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.

Very impressive and good quality, the sizes included are a plus so no need to order different sizes from a third party. The switches on the IEM could make a big difference, especially in bass department, you can feel it. Connectivity is perfect, just a 3.5mm jack is all that's needed for plug and listen. Ear support is pretty nice but could've been more solid instead of wire and plastic around the ear, but it works. Functionality is simple and nice. In my opinion, 9/10 listening experience.

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 iscoming 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

absolutely amazing price to performance on these iems. i use these with my iphone using the standard apple dongle. to my ears they sound great for only $20 some dollars. definitely grab if you want quality on a budget.
