Comfortable way to converse on my iPhone 5

Besides pro's and cons, its Logitech and I received basically free from by a get rewards points promotion. Volume is adequate. And my head really is medium-sized.

Works; has a microphone; in-line volume

A little tight on my medium sized head

The mic quality isn't good for taking conference calls. People feel you are distant from the phone while talking. The voice heard at the other hand is too thin.

I recently purchased this headset thinking it was simply a black version of the Logitech h150, only to find that it was different in one important feature; instead of the separate pink & green speaker and mic jacks, it only has a single jack.

Voice is super quiet and can't hear a thing, I have it plugged into my mic jack and turned up microphone boost on windows and moved it as close as I could to my face and I even talked louder but still very quiet voice, I think that the noise cancellation software is broken.
