Review: Long lived headset - I have used my 2400 II Duo headset for over 5 years and only just started giving me problems, and I wore them daily...that's nearly 10,000 hours. The new one came with the phone QD cord but I ditched it because the processor that cuts down on background noise was causing me to have to speak much louder than I usually do. Old cord matched up perfect and business as usual. The ear cushion design doesn't hurt my ears like other designs.
Review: Very nice headset for me it felt like it was too ... - Very nice headset for me it felt like it was too tight for my head. I had to return it. Return process was quick and efficient.

*by S***S on January 17, 2016*

Very nice headset for me it felt like it was too tight for my head. I had to return it. Return process was quick and efficient.

### ⭐ Have to buy an expensive adapter for it to connect to anything
*by H***E on May 6, 2020*

Product description did NOT say that this doesn't work with anything as is. What looks like the USB adapter plug in the picture is hollow. I am very disappointed.
