The unit has numerous features including talking caller ID, talking alarms and talking battery life indicators using text-to-speech, a blocked caller list, and night mode that allows different ring settings for each handset. The total number of handsets can be expanded to 6 total, and each one uses DECT 6.0, which is supposed to enhance call clarity and reduce interference with other wireless devices. The handsets have bright backlit LCD displays and backlit number pads as well. The KX-TG9332 also has a built-in digital answering machine. The batteries last for about 5 hours of talk time per charge.
