This is my fifth case from VaJa and it’s best design they have in my view. The book style iPhone covers that I also have, make it impossible for others’ to hear me. The problem according to Apple, is they block the rear microphone when folded back, and this in turn diminishes the sound imaging of the combined microphones.
The Top Flip case is a must for me. It's a little pricey, but very much worth it. It's a super-high quality leather case that exudes true craftsmanship. It is as durable and protective, as it is sleek and beautiful. You can customize it with an almost endless array of colors...although I've yet to do that. I pick a color combination that is in stock, so I can cover my phone as soon as possible. I've also sent one as a gift to my very picky, but lovable father and he was thrilled with it! That alone speaks volumes! I am a huge fan and will always have one for every new iPhone!!
