ziggyToo many reviews on that same Amazon listing that cite product failure and poor build quality... and one even says that these only have a 30-day warranty even when they're brand-new? While I love the earbud form factor, and it looks like this drop is going to happen regardless, going to have to pass.
AB01I have the PK3 and I can tell you that except for people that yank on their cords all the time no one should have an issue with these. They are not for jogging or active use but I've had my PK3 for a long time with no issues. The PK3 sounds great and these are a higher model so these should sound even better.
