An audio review & news blog. The volume should not exceed 80 dB is recommended. I usually adhere to the safe-listening style by WHO. Please note that my aural impressions and interpretations of measurements are also made from a safe-listening style.


(True Wireless Earbuds Review) QCY HT05 Melobuds ANC: Monitor-like sound balance with bright midrange; ANC reduced mainly in the midrange. High functionality with supported applications.

The QCY HT05 is a reasonably attractive option in its price range, with ANC that effectively reduces midrange, good communication quality, and a fairly balanced and bright sound signature.

(True Wireless Earbuds Review) QCY T18: For those who want to listen to well-balanced sound for a long time. Multi-point support & high communication stability.

The QCY T18 offers a very balanced studio-tuned style sound.

(True Wireless Earbuds Review) QCY T20: Inner ear low frequency idiot

The QCY T20, as the brand describes it, is a typical "low frequency idiot" with powerful heavy bass, a sound that I don't think is suitable for everyone. Personally, though, I like it a lot.

Revolutionize your everyday music with the QCY T17!

Have you heard of the "high-quality sound true wireless earbuds" that are now the talk of the town? "Yeah, I know! It's a SONY product, right? Or is it the Sennheiser one?" I'm sorry you think so, but it's not them.

We can't laugh at audio dreamers who are looking for true wireless earbuds that combine high sound quality with highly customizable apps at a low price point, just like the higher-end models. Because it is right in front of you: the QCY T1…

(True Wireless Earbuds Review) QCY G1: Gaming model with emphasis on midrange. Narrow soundstage. Stylish design. Only communication quality is a bit of a concern.

The QCY G1 has a midrange-oriented sound. The soundstage is narrow, but not bad for those who want to enjoy music and games with compact sound. The design is also stylish. The only concern is that the communication quality is a little weak.

(True Wireless Earbuds Review) QCY T17: Emphasis is placed on the sound field, and the sound is extended, fresh, high-resolution, and high-definition. However, the midrange is thin.

The QCY T17 has a refined sound that is a brighter overall version of the T13 sound. If you prefer a sound that is more delicate, brighter, fresher, and has a wider soundstage, the T17 is a better choice than the T13. I don't know if it is…
