Panasonic models dominate the cordless phone market, and while the Panasonic KX-TG6644B doesn't command the stellar user reviews the Best Reviewed KX-TG7643M does, it still performs excellently on a number of customer review sites. Hundreds of users say the KX-TG6644B has excellent sound quality and signal range, and that it's easy to use.
Taking a call 600 feet away. Reviewers praise the Panasonic KX-TG6644B's clarity, range, speaker phone and intercom systems; one reviewer says she can take calls up to 600 feet away from the base. Some say the sound quality is so strong they need to be careful not to set the volume too high. The few users who have complaints had issues with handsets that refused to connect with the base unit, or other hardware issues that affected sound quality or reception.
Few complaints from owners. The handset uses AAA rechargeable batteries instead of a standard 3.5-volt phone battery. One user reports the batteries last 5 to 7 hours, not 11 as advertised. Reviewers praise the lightweight design and belt clip for mobility and ease of use. The phone also cradles between the ear and the shoulder nicely, users say, and the sizable keypad has a backlit display with large text, making data easy to read. There are few complaints about durability.
A feature-packed cordless phone. Reviewers say they appreciate the plethora of features the Panasonic KX-TG6644B offers. Like many Panasonic models, the unit can use the handset battery as a backup when the power goes out, allowing the phone to continue to make and receive calls. It also features talking caller ID, announcing the identity of incoming calls as part of the ring, which many users cite as a favorite feature. There are keypads on both the handset and the phone base. Users say the option to store numbers in groups is a helpful feature, but that the 50-number limit is too small.
