Ok, forget the mini review. It didn't save on my Amazon, so I can't bring it up and don't wanna rewrite.
In short, don't waste your time with the KSC35 wireless. Just get the PortaPro wireless instead and buy some KSC75s with it to take the clips. The clips on the KSC35 have never been as comfy, and this hasn't changed with the wireless.
Also, the battery life is atrocious, and I can't even go through one whole shift before the KSC35 runs out of juice. The PortaPro wireless has double the battery life, so save up and get those instead.
To be completely honest, I wouldn't even go for those. After just over a year, one side of my Porta wireless stopped working/cable started to strip near the battery module. Aka, typical shoddy build quality on the cables. The KSC35 wireless looks just as bad in terms of cable quality. MY PORTA WIRELESS IS DEAD, AND USELESS NOW.
Until Koss decides to get off their arse and actually spend some time QC-ing their cables, I don't recommend ANY of them. I'm sick and tired of buying their clip ons, only for every single one to go bad within the year because of crap cables/connections and losing one driver audio every single time.
I hate it, because they're the only headphones that work for me while I work, but I'm fed up supporting them if they're not going to change a damn thing. Not to mention, but both of their PP wireless and KSC35 wireless have just a meager 1 year warranty. Best believe they WILL go bad shortly after, if it hadn't done so before.
With the KSC75, it isn't so bad because they cost so little, but I'm sure I've owned a new KSC75 every single year since I became a memeber here. Not worth sending them in for warranty when it cost almost as much to get them fixed by Koss, from shipping to warranty fee.
So Koss, if you ever get this, make a damn KSC75/35 with detachable cables. Probably something that uses MMCX connectors or something small enough. And USE A HALFWAY DECENT CABLE THAT WON'T STRIP AT THE ENDS. AND A PROPER STRAIN RELIEF EVERYWHERE. I'M DONE.
