I’ve used these every day on my computer and I have to say they are extremely comfortable and small, and loads better sound quality than I was expecting for the low price. I’m suprised by how strong they are considering I’ve had them ripped out of my ears and ran over by my chair( they still work fine). Great buy for someone on a budget

I have used IEMs for the past 5 years ranging from a variety of price points. This IEM is not the best out there, but for the price, it’s phenomenal. The build quality is excellent. Although the buds are quite heavy, it’s not uncomfortable at all. It sits perfectly on the ear. The ear tips might have been a bit better but still, it’s not bad. The cable is the same, not entirely bad, but other vendors have more high quality cables. Would have been nice to have a pouch but I’m nit gonna ding it for that for the price it’s askingThe biggest thing for me was the sound clarity with the increased bass.I wanted something a bit bass heavy than something more balanced while maintaing a clean soundstage. This hits the right spot definitely. The bass is punchy and tight, whilst not making the mids and highs muddy. The mids are a bit recessed but that is expected. The highs are clear and not piercing which some IEM tend to do. The stock switch configuration ( there are 4 switches for increasing the sound level) isn’t bad, but making the first three on does make the sound more enjoyable to my preference as I listen to hip-hop, R&B and EDM more than other genres. I would definitely give the sound a 10/10 compared to others like the Waner, Salnotes and Zero 2. They are also good, but the sound is rather balanced and lacking in the bass department compared to the Castor.P.S. Sound Quality and Preference is entirely subjective. What might be good for me might sound the worst for you. If you prefer a good entry point IEM which tends to be a bit bass heavy, I would highly recommend the Castor. It does compete with other earbuds in much higher price points. Apart from the eartips and the cable being a bit cheap, it is overall one of the best IEMs under 20$!

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.

Update: Seller offered a refund even though it was outside the return window. Appreciate it. I will still say the earphones sound really good, I probably had bad luck with that specific piece.Original:Pretty good quality while it worked. One side stopped working after 2 months. Out of luck! :(

Awesome for the price. A dynamic, warm, slightly bassy sound with eartips that fit really well and ear hooks that hold everything in place nicely. The adjustable tuning is nice, but I leave mine all off—the default sound is best to my ears.

Amazing quality sounding IEMs for a sub $30 price! These are hard to beat at that price point.
