These are the first headphones worth more than 500 pesos that I've bought; from my Lenovo HT30 to these QCY H3S, it's a huge leap, but be careful, the default audio is poorly equalized. You definitely need to equalize it or at least download the QCY H3S app in movie mode and activate the noise reduction to enjoy it a lot, or activate LDAC in movies, otherwise you'll have audio delay. That only works in music; if you prefer to use it on a PC, you'll need to find the Peace Equalizer app, watch a video on YouTube, or ask Google's AI to give you a peace equalization for watching movies (optional). Tell it the series or movie you'll be watching, and it will give you the best experience. For that series or movie, you can save many equalizers so you can have one for everything or one for each thing, even exclusive ones for gaming. I'll give you an extra tip: Dobly Atoms and Peace Equalizer are another thing to consider, they are amazing headphones if you adjust the equalizers, but the factory audio is poor.

Feels very high quality for the price. The headband adjustment is *extremely* stiff but once adjusted to your head i consider this a benefit. Anc is quite powerful and the wind setting in the app completely cuts out wind noise. Sound i would say is less balanced out of the box and with qcy's app eq than the original h3, likely due to the dual drivers. A parametric eq resolves this and leaves you with a wonderful set of headphones, better than the h3, i would consider it mandatory. Battery life is extremely long as well, you will not find a more feature rich headphone for the price.

Side note i purchased these in white previously (only option at that time), and gave them away due to them being almost paper white. This scared me off getting the gray which looks unique and very nice online, stuck with plain black which looks plenty good to me.
The finishing also punches above the price and it feels great to hold, folds well too.

I was torn between the QCY H3 and this product, but I think I made the right choice with this one because it has a high level of immersion. The feeling of being a bit heavy when wearing it is unavoidable since it's wireless. Still, I'm satisfied with the sound as the bass is well emphasized.

Very good for the price, very light, good passive isolation and fit my big head well :) app is reasonable, can avoid sign in with the 'guest' option, allows custom eq, more anc options, and various power down options. not tried out and about yet but considerably reduces noise when using power tools.

QCY H3S is amazing, delivers what it promises, authentic brand authentication (original)/official, incredible isolation, very soft, powerful ANC, lightweight, compatible, the app does its job very well, the headphones are sensational, the delivery was super fast.

The cost-performance ratio cannot be matched by QCY.
Compared to the previous H2 model, the battery life has been slightly reduced, but since it's for indoor use, it's not a big inconvenience.
After adjusting the equalizer a bit, it's usable for PC use.

Very good product. It fits perfectly in the ear, the noise reduction is very efficient, very good indeed.
There is no possibility of connecting to two devices at the same time and with Bluetooth 6.0.

I liked it, as expected, I hope it lasts, it's my first QCY.

Very good sound and good headphones, the best part is that I got them super cheap.

It arrived before the deadline. Well packaged. The sound reminded me of others with a strong bass, but it accepts equalization well to suit any musical taste. It arrived with the battery at 80%. I used it for 7 hours, with about 4 hours of ANC turned on. At the end of the day, the battery showed 60%. For indoor environments with air conditioning and loud conversations, the ANC was impressive, eliminating external sounds 99% of the time while maintaining sound quality. Throughout the day, I noticed some quick glitches in the sound that I haven't yet identified whether they are from the Bluetooth or the internet. It's not a detailed and clean sound like that of a reference headphone or an IEM, but it's pleasant and enjoyable, and also comfortable to wear for several hours.

I've never left a review after buying something on Ali, but I'm really fed up... I used the 16th anniversary event and various discount codes to buy something for around 20,000 won. Is this really a genuine product? When I adjusted it to the EQ recommended on the internet, it feels similar to the 30-40,000 won Sony headset my girlfriend uses;;; This is really unbelievable... haha. I didn't expect much because the price was so low, but I was surprised. I bought it for home use only, so I'm not sure about the noise cancellation performance, but the spatial sound function was better than I expected. I tested the battery by playing Netflix and music for about 2 hours after opening the box, and the battery condition was just as good as the first time... If you can buy it for around 20,000 won, definitely buy it;; I'll recommend two EQ settings. The first one has the best balance that I've received the most recommendations from people, and the second one feels like it emphasizes the bass a bit more. Both are good, so I've registered both and switch between them when needed.

very good

Headphones are of high quality, 10 out of 10.
Premium plastic, pleasant to the touch
There is nothing shaking or loose anywhere.
The noise cancellation works brilliantly.
The bass is also decent.
The ear pads can be replaced, but they are not included in the package.

Best value for money headset! It seems to be the best in its price range at under 40,000 won. The default EQ (after updating) is well balanced. H4 is an older version, and H3S is an upgraded new model (released in October 2025). It blocks noise and has ANC that is 78% as good as high-end products, and the function activates at about 50%. The material called "headset" makes the sound and external noise less noticeable. The only downside is that when the volume is high, you can hear the sound leaking from right next to you, but the price is good.

The delivery was a few days before the final delivery date.
It came well packaged and without any apparent damage.
The headphones work well and came with a battery when turned on; so far, the noise cancellation impressed me, as did the sound. We'll see how it holds up with use.

Excellent alternative for those looking for good sound, comfort, and simple controls. The bass is strong and the treble is clear, there is almost no distortion, and the ear pads feel comfortable. Balanced sound and they are lightweight. The only criticism is about the adjustment to the size of the head; the mechanism feels a bit fragile and it's a bit difficult to reach the extremes, but otherwise I recommend them.

The qcy h3s offer excellent value for money. The sound is clear and balanced with strong bass, the comfort is great even for long use, and the battery life is impressive. Overall, a highly recommended pair of headphones for the price.

The cost-performance ratio of the QCY H3S is very, very good.
The mid-bass and high-pitched sounds have been enhanced, which seems to greatly affect the type of music.
Good for vocal-oriented music
Rock, metal, jazz, and that's it.
Cost-effective wireless over-ear headphones equipped with a powerful hybrid ANC (active noise cancellation) system at a level of 56dB and a dual driver system of 40mm mid-bass drivers + 13mm tweeters.
