Launch products can have software bugs (or hardware defects) that will need to be ironed out, and TUAW may have discovered an issue we were initially unaware of. The TUAW investigative team did a few unscientific tests and a little bit of a Apple research (perusing through support forums), and maybe verified the following.

While testing out the Jawbone Icon wireless Bluetooth headset recently, the parties I called complained of diminished sound quality on their end. They talked about overly compressed muffled sound, with decreased dynamic range. Over at the Jawbone end-user forums several threads have been discussing exactly that.

It turns out that problem is not isolated to the unit I tested, let alone the manufacturer. At Apple’s discussion forums, other Bluetooth headsets are apparently producing the same distortion effects when used with many iPhone 4 units.

TUAW questions whether this issue is related to the iPhone 4 antenna issues (it might be), but I’m not ready to confirm that just yet. For those of you with bluetooth headsets, how has your experience been with the iPhone 4?
