Stop paying for those branded use-and-throw crap, and get yourself one of those modular chi-fi headsets.
Cables broken? Now you don’t have to throw the entire thing. Want this, but in USB-C? Just get them cables in the format you prefer. Earbuds uncomfortable? No worries, get them replaced. Want to go wireless? Get yourself one of those Bluetooth module - the neck ones, or the around-the-ear, if that’s what you prefer.
The big problem with KZ and related brands like CCA is stealth revisions (selling a new model under the same name as the old model without telling anyone) and quality control issues. The CCA CRA has to be the most egregious example of a stealth revision, the new CRA sounds completely different to the old one. But otherwise they usually deliver a good bass and treble heavy V shaped sound signature for a cheap price.
Yeah I spent two days researching, so I now know about issues of KZs.
I’d like to get Hexa, find comfortable eartips, and try doing a little bit of EQ, but 20 dollar options (many of them) also look very good.
