I've just bought one so expect something within 7-10 days, and i'm going to compare it against my modded TF10 bluetooth cable, to see the battery life and if the chipset is any better.

that's pretty disappointing, if it was like 2 hours it wouldn't be too bad, but also it's worth opening up if you could fit a larger capacity battery in, as single cell Li-Pos are pretty cheap, still going to give it a go when i can find one.

Has anyone noticed that KZ has a 1st party bluetooth cable for the ZSTs? as soon as some sellers get one not bundled with the ZSTs, i might have to see how it sounds next to the TF10 cable i bought a few months back.

after falling in love with my ZSTs, would anyone know which connectors would fit them, as i'd like to be able to modify a bluetooth upgrade cable to fit them, as i've looked around aliexpress, and ebay, and couldn't see which connectors would fit, although ultimate ears triple Fi 10 connectors...
