  1. Have trouble hearing on a cell phone? This product is your answer! Review by Liam
    Overall Satisfaction

    I rarely write product reviews, but in this case I’m making an exception. Before I purchased this amplifier I rarely was able to make phone calls on my cell phone, Hear All changed all that. The amplification is more than adequate; in fact, it is so loud you may need to consider that other folks will be able to hear your conversation. That said, the volume control comes in handy, both on the amplifier as well as your cell phone itself. You can leave your cell phone on your desk or in your pocket and simply use the amplifier itself to answer calls. Highly recommend it. (Posted on 3/1/2018)

  2. Finally! I can enjoy a phone conversation! Review by Jan
    Overall Satisfaction

    After a lifetime of hearing loss I have a deeply ingrained aversion to talking on the phone. It's never been pleasant.
    I've tried everything. And even after finally finding great hearing aids a few years ago, I still haven't been able to hear very well on the cell phone.
    But I keep trying. A couple of weeks ago I tried this. I'm SO GLAD I did!
    At home I love using the speaker option. The sound is crisp, clear and loud. It pairs with my iPhone in a snap and seems to hold a charge nicely.
    The people I talk with on the phone say they notice something different - but not in a bad way. They can hear me just fine too.
    Try it - you won't regret it. (Posted on 5/15/2017)

    Overall Satisfaction

    We have tried the Hear All with a couple of our clients who are hard of hearing already and they feel that this product will make it possible for them to use their cell phones more successfully- not only in a quiet environment, but in a noisy car as well.
    We were surprised at how much the device amplifies, and the three tone settings can help even more.
    The pairing process is easy and the handset is a good size and easy to handle for older and younger clients as well.
    We will be recommending this product to our clients from now on- Thank you! (Posted on 2/17/2015)
