Cheaper versions are available for this which unfortunately I bought before I found the Plantronics brand. Having tried several brands I can recommend this for sure.

I'll definitely continue to buy as the need comes up because it's an overall good value for the price when compared to competing products.

The headset is easy to setup and works great with my ShoreTel 485G office phones without the need for any additional parts; I have purchased 4-5 of these (including one for me) and we all enjoy them.

I haven't found any cons yet

We purchased these since our office floor uses wireless headsets for mobility. Having over 100 employees using headsets in the general vicinity of each other, we opted for the XD version. No issues yet!

A good radio for short range/line of sight. You're not going to get huge range with a license free radio since they are only 0.5W. But these T40s are still very useful to have for walks, days out etc, and they also work in a car convoy (although only to a certain distance).

comfortable to wear.decent sound quality

good build quality

nothing if on sale

This Headset is very comfortable and also extremely clear. So far, has exceeded my expectations.

Sound quality is absolutely wonderful! Wireless range is very nice. Looks good sitting on my desk, and is comfortable enough to wear all day. I also like the fact that when I have it on, it doesn't block external sound from my ear like wearing some ear buds do.

I bought this headset exactly one year and one month ago and the device will no longer charge. I spent a good chunk of change on this device for it to not work after a year and one month of use.
