Review: Ya, sounds really good! - 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.
Review: Solid and value oriented - So far they work better than any headset I have ever owned. The chord length is good for my needs but I could see how one could need longer. They are heavier than most wireless earbuds but that isn’t a dealbreaker since they replaced a headset. They are crystal clear and do not distort in my use case. Left and right on the wire plugs are not the easiest to see, minor gripe. They are easy to plug in and play. They do not hurt my ears for the few hours that I use them at a time.

### ⭐⭐⭐⭐⭐ From one musician to another, you wont regret it.
*by T***E on January 11, 2026*

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.
