QCY Crossky C30S User manual

great buds specially for their price

i was a happy owner of the crossky c30 that i gave to someone to buy this pair, and i have many other earbuds to compare it to, and i decided to make a rather intense music hearing test, with the soundcore aerofit 2, and the soundcore liberty 4 NC.

the aerofit 2 is an open ear earphone with an over the ear fitting and costs about 3 times the crossky C30s, and the libery4 nc is an in ear earphone that gets much deeper bass, but there is no open ear earphone bringing as much bass than an in ear earphone.

the crossky and the aerofit to both give a very good sound that is very similar however the aerofit 2 brings more details. This is not strange considering that both the aerofit and the liberty have a golden sound feature that is made to adapt the equalization corresponding to the specificity of your audition and the C30 S doesnt have that.
The great plus of the C30S is of course it's price, but also the facility to wear it compared to the over the aerofit. So if you want a budget open earbud the qcy is very good.
the qc30s are slightly better than the qc30. the main improvement is the reactivity of the controls, but the sound improvement is not sufficient to change the qc30 to the qc30s. if you are about to choose between the qc30 and the qc30s choose tehy qc30s. but do not upgrade specially.
what i didn't like in both the qc30 and the qc30s is the absence of sound return when you hit a control.
that's all folks
