I have gone through 3 sets of these headphones in the past 6 months. I have the same problem that many other people report: they work fine at first, but then the antenna goes bad, and the message "Check Antenna" appears on the Inno's screen.I bought my first pair on eBay; that pair lasted 3 weeks. I bought another pair from Amazon; that pair lasted 2 months. Belkin replaced the 2nd pair free of charge. The replacement pair lasted 2 1/2 months. I have no doubt that Belkin will send me another replacement, but it is a pain in the butt to have to ship these things back to the manufacturer every 8-10 weeks.Unfortunately, these are the only signal-boosting available for the Inno at the moment.
