This is an excellent case to amplify your iPhone's speaker volume. The case is well made and easy to use. See the demo video below.
HOW IT WORKS
The FADI protective carrying case, also known the Audioglove, is designed in such a way that the user can open the case and redirect the sound toward him/herself. This audio enhancing functionality is not offered on any other protective carrying case. The Audio Glove enhances and amplifies the volume and quality of sound emitted by the iPhone. It’s simple design corrects a fundamental flaw in the iPhone that suppresses good quality sound and tone production. The retractable audio drawer on the FADI Audioglove eliminates the need to attach external speakers. Now you can amplify the phone without restricting its mobility and ease of use. As an added bonus, the Audioglove makes the speaker-phone sound warm and full for people on both ends of the call — now your iPhone can operate as a hands free device without a Bluetooth accessory! - Posted using BlogPress from my iPad
