Review Content I love this device I use this product every day to enhance my iphone. The audio is enhanced greatly. Works amazingly well I am hearing impaired and have some difficulty with phone use. This device is perfect and works amazingly well for anyone with even slight hearing impairment. My hearing loss is significant and this device is simply wonderful. Good amplification I have had a number of phone amplifiers and they did not give me clear tone or volume I needed to hear. This phone amplifier real,real does the jub, and does it well. Finely I can hear clear and distinct from my cell phone. Thanks Guys and gals. I would reccomend this product to anyone that uses an aid. Good tone & fidelity. Easy to use with hearing aids,& plenty of volume. I would buy this product or similar again It was almost imposible to install the battery, even with removing the paper label.I was afraid of breaking the case.
