Here's a chart of all the models in the line:
| Model | Number of handsets | Color | Answering machine included? |
| LS6215-2 | 2 | Black | No |
| LS6225-2 | 2 | Black | Yes |
| LS6225-3 | 3 | Black | Yes |
| LS6205 | Additional handset | Black | n/a |
Note that VTech offers comparable--but not identical--DECT 6.0 models with very similar model numbers, including the LS61x5 line and the CS62x9 line.
Performance
DECT 6.0 (Digital Enhanced Cordless Telecommunications) operates in the 1.9GHz range and is designed not to interfere with other electronics in your home, such as microwaves, Wi-Fi networks, and baby monitors. It's also supposed to offer extended range (up to 200 feet), though distance will vary depending on obstacles and the material in your walls.
Most DECT 6.0 phones offer similar range, but they're not all equal. In our tests, we found that the LS62x5 series didn't do quite as well as Panasonic's KX-TG6400 series. The Panasonic offered about 10 feet more of range before the connection with the base unit died.
Call quality was good and clear overall and we got ample volume.
Verdict
The VTech LS6225 series may not have the deepest feature set or the strongest performance in terms of range, but it is one of the sexier looking DECT 6.0 models. Also, it's expandable up to 12 handsets and is relatively affordable with a three-handset model coming in about $80.
