## Customer Reviews

### ⭐⭐⭐⭐⭐ Good for the price
*by A***S on September 2, 2025*

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.

### ⭐⭐⭐⭐⭐ Ya, sounds really good!
*by K***J on March 7, 2024*

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.

### ⭐⭐⭐⭐⭐ Amazing quality and sound!
*by T***P on July 25, 2025*

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.
