A:AnswerHello! Hearing aid compatible means people who wear hearing aids will be able to hear on the phone while wearing their hearing aids without electronic interference. Not all phones have this capability, especially some cell phones. However, this phone is, indeed, hearing aid compatible. I know this because I, myself, wear hearing aids and I can hear just fine with this phone while wearing my aids.
A:AnswerThere is an Answering System on the unit. The answering system can answer and record
calls for you when you are unavailable to answer the phone.
A:AnswerHi Kevin! The call log history on this phone is also limited to 50 entries. It stores caller information for the last 50 callers, listed from the most recent to the oldest. - S
A:AnswerHi Winston! Thank you for your question. Wired headsets can be connected to the handset using the 2.5mm headset jack. Some Bluetooth headsets that are compatible include Jabra BT2070 and BT2080, Plantronics Voyager 520 and Voyager 5Pro+, and Samsung WEP-450. Please note that Bluetooth headsets must support the HSP (Headset Profile) to work properly with this phone system. - S
A:AnswerHi there! The sound quality is good, but for hearing aid users we recommend our amplified phone systems, such as the KX‑TGM series, for the best experience. - S
