I was able to pick these up for a bit less a couple of months ago, and I will say that I've been pretty impressed with them. I've really had a hard time finding wireless IEMs I like, for a variety of reasons. I've never had a neckband style IEM before, so I took a flyer when I saw them on the cheap - and it paid off.
The sound quality is good, with a bass-oriented tuning - definitely not neutral - but it's quality bass, not sloppy or boomy. The comfort of the neckband is way better than I imagined. It's extremely light and easy to forget it's on. Klipsch ovals are my favorite silicon tips (obviously a personal fit thing), but if they work for you they're great as far as seal and isolation.
I think these are a no brainer for wireless IEMs at $60 with a legitimate 18 hour battery life.
A couple other comments and general responses to the thread, since I've been using these quite a bit recently.
1. I'm usually in the "No deal, you can buy these for the same price on Amazon" camp. But I took a quick look and I think there's actually a legitimate reason to buy them here. It looks like the sellers on Amazon are third parties - I didn't see them being sold by Amazon itself. It's easy to get burned buying from third parties like that. Most are legit, but some are selling counterfeits. I would also suspect that they are not authorized dealers, so no warranty if there's a problem.
2. I wouldn't recommend them for exercise. The complaints about failing due to sweat are pretty consistent in reviews and, while they are stable walking around and doing light stuff, I can't imagine wearing these for a serious gym session. Honestly, they're too nice for serious workout anyway - they just scream "poser"
3. There isn't a way to lock the buds in place like with the LG tone. While I wish there was, I haven't had any issues with tangling (and I hate it when my schwartz gets twisted!). I often walk around and do stuff with them dangling - I have a family, so the surest way to get them to talk to me is to put a pair of headphones on. (As near as I can tell nothing bothers women and children more than a man relaxing and enjoying his music).
4. In general, buying last generation Klipsch's as they end their marketing cycle has been a winning strategy for me. I've picked up the X11, R6i, and these, and all three are in the quality to value hall of fame at their stock clearing prices like this.
