From my experience with these earbuds, that’s about 2 and a half weeks now - These are a great pair of earbuds, the sound quality is very good, no complaints. The ANC is good for the price and blocks out a lot of noice even though they let voices in quite easily which is quite annoying, that’s a problem with most ANC earbuds and headphones based on my experience. The transparency. That is on a whole other level, it’s almost on par with the AirPods Pro 2 for example. The MeloBuds are almost hearing aid-esk and I was very shocked. Although be careful because it can be loud, but that’s adjustable with the app (You have to use the app to even get the good transparency), you do have to be patient when it comes to switching between ANC and Trasnparency mode since it takes a little while for them to switch, and when switching between the two through the earbuds I find it annoying that it goes from Transparency to ANC and to then go to ANC off. I’d rather have just ANC and Transparency as an option instead of three different ones which can be annoying when your commuting in cities, etc. And on the topic of touch controls, no complaints except for the Mode Switch. The weight is good, the case too. The only complaints I have are the QCY app and the substantial battery decrease when you use LDAC.
