I recently lost my second Motorola HX550 and need to buy a replacement. While I love many things about that headset, two annoyances popped up when I upgraded to the iPhone 5: It randomly loses audio during a call. I have to switch audio to iPhone and back to Headset to restore it. When calling another cell phone, the first couple of rings are so loud in the earpiece, it's literally ear-splitting. While I realize the solution to the second bullet is to simply turn down the iPhone volume, my ear is ringing by the time I think of it. Aside from these gripes, the HX550 is the best headset I've used. It has great audio quality both ways (as long as you set wideband audio in the settings), terrific range, works perfectly with Siri, does streaming audio, and has easy on/off with the flip boom. But it's a model that's now several years old, and I'm wondering if there's something even better out there from Motorola or another. I don't want to spend more than $70. Bose is not happening. Suggestions? Needs to have a great track record with the iPhone 5.
