I'm starting to wonder if wired headphones are the only truly reliable way to use the iPhone hands-free and particularly to use Siri while driving. I've owned a number of bluetooth earpieces with decidedly mixed results. This is getting expensive and frustrating. I'm really hoping someone here can point me to a bluetooth earpiece that works really well with the iPhone and Siri. I've ponied up for some higher-end earpieces in the past which include: Original Jawbone Jawbone II Plantronics Savor M1100 The Jawbones can be buggy, and the fit is tricky particularly since the little rubber nub needs to rest on the cheek. I ended up concluding that I didn't like that style of noise cancellation. I've also found them to be uncomfortable in my ear, pretty much a deal-killer. There are many things I like about the Plantronics Savor. It's super-light and fits so comfortably in my ear (without a loop) that I hardly know it's there. I love the discrete on-off switch (pressing and holding a stiff tiny button for 5 sec is a real pain). BUT, that switch turns on in my pocket (not a deal killer). AND, it has a hard time maintaining a strong link to the phone (quickly becoming a deal killer). On this second point, I've found that if my body is even slightly between the phone and the earpiece, I get bad static. Even if it's not, and the devices have a clear line-of-sight and maybe 3 feet of separation, the signal can crackle in and out. This is inconvenient for calls and completely messes up Siri recognition. I already had Plantronics replace the Savor and the new one worked better for a while but is now performing worse. I think it's a flawed design. I really need a good solution. My criteria are: Good sound quality including noise cancellation Comfortable fit Discrete on/off switch if possible No issues holding strong signal link with iPhone Straightforward interface Full iPhone compatibility Known to work well with Siri Less than $100 if possible One that appears to meet most of my criteria is the Bose Series II. It's more than I want to pay, and I don't like paying for overpriced brand names, but the Amazon reviews are pretty stellar. Thanks!
