QCY | Noise Cancelling Wireless Semi-In-Ear Bluetooth Headset Long Battery Life Sport

Overall, I think it's quite good. The default EQ has a slightly narrow soundstage, but switching to the original sound enhancement EQ can help add some bass and open up the soundstage, which I really like. It does its job well as headphones. There are many impressive details, like being able to adjust the prompt sound volume, the app operates smoothly, and when you enable game mode, the delay is kept at a decent level. The active noise cancellation is marketed as balancing the pressure in both ears by calculating the noise reduction for each ear, but in practice, the noise reduction can differ between ears, which might lead to a feeling of pressure on one side. The app doesn't allow turning off this function or adjusting the noise cancellation depth, which is a bit puzzling. Moreover, it seems that the active noise cancellation doesn't handle wind noise well, and you might notice some background noise in quieter environments. The noise reduction isn't overly strong, so it's best not to expect too much (after all, it is just a semi-in-ear headphone). The touch controls could be a bit more responsive, as they can be easily mis-tapped. Also, the shape of the headphones doesn't fully fit my ear canal; no matter how I adjust them, the fit isn't perfect. However, they are definitely more comfortable than in-ear styles, even though there is still a bit of a foreign object feeling.

The sound quality and noise cancellation are great, even better than the Vivo TWS Air 3 Pro. Battery life is also superior to the Vivo TWS Air 3 Pro, and the comfort of wearing them is exceptional, definitely better than the Vivo TWS Air 3 Pro.
