Sorry to hear that, Gordon. Losing a parent is a terrible experience. I can sympathize too well, unfortunately. I've lost both.
Now, turning to PX100 ii, let me just say that I don't honestly believe reporting the issue to Sennheiser is going to be as effective as talking about what is wrong about the product online. Corporations simply don't work that way. I might get a polite response from them saying they will forward my complaint to their engineers but that usually doesn't mean much. What they might pay attention to is the user ratings, and -- believe it or not -- threads like this. It is obvious reading the Amazon reviews that lots of folks bought PX100 ii influenced by Katun's gushing praise right here. I am not shocked by that. That's how internet sales work these days, it seems.
Still, I am going to take some time to compile a complete list of cable-specific complaints from Amazon and elsewhere and send it to them, so they know this isn't just one person having a bad experience. Amazing that I'm willing to take the time to do something like this. Goes to show how much I enjoy the sound and comfort I am getting out of these. (Now, if they ever made one with detachable cable, Katun's praise would be painfully understated.)
Also, let's not be afraid to consider another factor, which I've already mentioned in an albeit inappropriate context... Planned obsolescence is actually no joke. Companies do this. And it should not be tolerated. What else would explain the fact that so many cheaper products come with better cables and secure connections?
While it is true that "the overwhelming majority of reviews on Amazon give them 5 out of 5," those who don't mostly complain about this one thing. That should have been prominently reflected in Katun's review. Since it wasn't, I will be happy to bring it up here - repeatedly, if I need to.
