Clarity AltoPlus™ Phone Reviews – Seniors Model

Clarity AltoPlus™ is a popular choice because of its hearing aid compatibility. Seniors need to be careful when selecting amplified phone options to ensure that they only select those compatible with their hearing aids in order not to damage them.

The AltoPlus™ is suitable for people with severe hearing loss, according to the product details provided by the manufacturer.

Who Manufactures the Clarity AltoPlus™ Amplified Phone ?

Clarity is a company with a long history and was founded by Wesley Walker from North Georgia and initially called Walker Equipment.

The company started manufacturing handsets for public telephones and by 1977 had a breakthrough with the patent of its Diode Bridge—a technology necessary for amplified handsets.

This breakthrough helped the company to develop the world’s smallest and lightest test set in 1984.

In 1986, Plantronics acquired Walker Equipment and expanded into international markets. In 1989, the company introduced a patented amplification technology called Clarity Power™.

Less than 10 years later telephones made by Walker Equipment were being sold across the United States, and across Europe.

The company changed its name to Clarity because of the success of its Clarity Power™ products. It has grown over the last four decades to become the U.S. leader in amplified telephony.

The company boasts of several accomplishments in the industry which include the first phone with digital sound processing, first cellphone for seniors; and in 2010, the first remote access technology for telephones.

Furthermore, the Clarity brand has a wide range of additional products to assist seniors with other hearing loss related needs they face as they age. These include reduced vision, mobility, and dexterity issues.

  1. Hi Ceci,

    Thanks for introducing us to the Clarity AltoPlus for people with hearing loss. It’s good to see that a company is willing to help them with incoming phone calls for daily communications. I love how they make it audibly and visibly to tell you who is calling, which enhances the quality of life of seniors and the elderly indeed.

    I have concerns about the TIA-1083 compliant for hearing aid, meaning it is compatible with all hearing aids? or only those hearing aid models that are also compatible with TIA-1083? People need to be careful about this, right?


    • Thanks for the comment Matt.
      Anything that is certified as compliant with a regulatory standard is generally safe. So it is only for hearing aids compliant with TIA-1083. As usual, readers are encouraged to discuss with their hearing specialist for additional information and guidance.


  2. Thank you very much, Ceci, for this valuable and detailed information! I am searching for a telephone for my aunt, and Clarity seems to be good enough. She doesn’t need the phone to expand. The features are already excellent. So, I am pretty much pleased I don’t need to look any further. Keep your great work up!:)
