Hamilton CapTel 2400i Captioned Phone
The CapTel 2400i is a captioned home phone that shows written captions of what callers say on a large touchscreen, a practical aid when amplification alone is not enough to follow conversations. The captioning service is federally funded and free to people with hearing loss who self-certify eligibility, though it requires internet. It is an assistive communication device, not a medical or hearing-treatment product, so pair it with a hearing evaluation if your hearing is changing.

Clarity Professional XLC3.4+ Amplified Cordless Phone
The Clarity XLC3.4+ is a cordless amplified phone offering up to 50+ dB of incoming boost and a 95 dB ringer, designed for seniors with significant hearing loss who still rely on a landline. Its talking keypad and high-contrast display also help those with low vision. Set amplification gradually to a comfortable level, and remember that a phone that boosts volume is an assistive tool, not a treatment, so ongoing or worsening hearing loss deserves a professional hearing evaluation.

| Outgoing amplification | Up to 15 dB boost for soft speakers |

Our verdict
These solve the phone problem two different ways. Pick the CapTel 2400i if you miss words even when calls are loud and want to read live captions of what callers say; the captioning service is free for qualifying users but needs home internet. Pick the Clarity XLC3.4+ if louder is what you need, with up to 50+ dB of boost and a 95 dB ringer for severe loss, and you'd rather use a simple landline without internet. Neither replaces a hearing evaluation if your hearing keeps changing.
Frequently Asked Questions
- Should you choose captions or amplification?
- It depends on why calls are hard. If words are unclear even when the call is loud, captions solve that — the CapTel 2400i shows near-real-time text of what the caller says. If the problem is simply volume, the Clarity XLC3.4+ offers up to 50+ dB of boost, which suits severe hearing loss.
- What does each phone need to work?
- The CapTel needs home internet plus a phone line, and captioning covers U.S. calls only. The Clarity needs a landline or VoIP line but no internet. That requirement often decides it before any feature comparison does.
- Is the captioning service really free?
- It is provided at no cost to qualifying users because it is FCC-funded, and in-home setup is included. You do have to complete a registration certifying hearing loss before captioning can be activated.
- Can the person be heard as well as hear?
- The Clarity also amplifies your outgoing voice by up to 15 dB, which helps a soft speaker be understood — something the captioned phone does not do. It also has a 95 dB ringer with a visual flasher, though volume set too high can be uncomfortable. Discuss significant hearing changes with an audiologist rather than only adding volume.
