Excellent product overall. Very good sound quality and a spectacular noise cancellation system. The finish is okay, but for the price, you couldn't expect much more than what it offers. The cost-performance ratio is unbeatable in this price range.

The headphones are very comfortable for my two types of use: working for long hours and going to the gym/running. Even with glasses on, he doesn't hurt you. Regarding the audio quality, I didn't notice much difference from my Philips TAA4216. When it comes to bass and noise cancellation, it's a whole new world. You will have powerful bass that is ideal for keeping you energized during sports activities. If you want to emphasize the midrange more, choose "popular" on the equalizer. The noise cancellation is so incredible that you can't hear a person speaking in front of you or the noise of many cars during rush hour. By the way, my impression is that the more continuous the noise, the better the cancellation. Higher-pitched and more focused sounds tend to penetrate the barrier. Anyway, you can buy without fear!

The headphones are great and very comfortable! The audio is very pleasant to listen to, and it doesn't cause any discomfort to the ears! In the brand's default equalization settings, I already felt good bass and very pleasant mid and high frequencies! The Hi-Res (LDAC) ANC and transparency functions work very well. The H3S has a very clean sound, bringing out a lot of details in the music! The QCY H3S is sensational.

Perfect, the ear fits very well inside the ear pads, so there's no discomfort even after wearing it for many hours, the color is beautiful, and it has good insulation.

Good value for money. The finish is quite basic. Don't expect a headphone in this price range to have the appearance and performance of more expensive headphones. The functionality is great. The sound isolation is impressive even with ANC turned off. I really liked that the setup done through the app is maintained when connecting to other devices. What's bad: it makes a lot of plastic noise when moving your head: it seems like it's going to break. The equalization (done in the QCY app) only works in the ANC off mode.

The sound quality is excellent, very good.
The construction of the earphone is also good
But after 3 days of use, a noise has started on the left side of the earphone that is quite annoying.

For the price, it's more than excellent.

I bought 2, one for my wife and one for myself. The quality is amazing, I've been using it every single day while working, for listening to music, meetings, etc. My girlfriend uses it while studying with the active noise cancellation feature, which we find excellent. For me, the only thing that was disappointing was the limitation on using the microphone while connected via Bluetooth to the laptop, as the microphone's audio input gets cut off too often due to the hands-free connection that laptops usually have. When I use the wired microphone, it works perfectly. Therefore, they should send a longer and higher-quality cable in the box. For those who use Discord a lot in meetings like me and insist on using it wirelessly during meetings, I recommend looking for a headset with a wireless connection.

I loved this earphone; I was considering about 3 different models, but I don't regret my choice at all; the earphone is great.
Everything about it is amazing, especially the ANC.

The headset is absurdly amazing, i have the qcy h3 pro and i was able to make the comparison between both and the h3s is much better in the construction of the equipment itself and also in sound, it is amazing and i highly recommend it.

It arrived super fast here in Salvador. Very good quality, comfortable and beautiful. I didn't think it was as white as shown in the picture; it's white but more of a beige color. Or maybe it's a reflection of the ambient light. But it's beautiful, original, and durable. It saved my days at the office from having to listen to random and boring conversations haha.

The product is simply sensational, high-quality sound, well-presented bass without exaggeration (exaggeration via optional app), very clean and defined sound, exceptional noise isolation. Fast delivery, and the order arrived without any problems, no dents or anything like that. The product was well-packaged and carefully delivered. QCY is excellent quality at a minimal price.

The best headphones I've ever bought, I recommend you create a custom sound configuration, I didn't like the pre-programmed settings. I'll include my configuration in the images, it turned out great, name test2.
