Excellent - like new and works great!
Im very satisfied with this product! Even though it was used it looked like it was brand new out of the box. It works great and is exactly what I was looking for!

Not compatible
Very disapointed to find that this product is not compatible with our Cisco desk phones that we use in the office. Tried every single troubleshooting options available, multiple user manuals and AI "support" chats regurgitating the same things I had already tried. Absolutely no way to talk to an actual person to find out if I'm doing something incorrectly, but I tried every possible combination of channel configuration, headset v phone plugin, etc and I absolutely cannot get a dial tone on the headset, and when I make/receieve calls neither person can hear anything on either end. The only explanation is that none of the configurations (a-g) are compatible with our phone. This is especially disapointing since we have been using a plantronics headset for years with no problem, but an identical setup with a new headset doesn't work. There is also no way to check for compatibility, since "office phone" or even "home phone" are not listed in the drop-down menu. Will be returning soon. Very frustrating.

Wireless headset
This works great! I love not being leashed to my phone with a wired headset. My only complaint is that it does not fit tight enough as it slips off my head and I cannot figure out how to use it just clipped over my ear.

Ideal work from home headset
I received this item in a very timely manner and the product it self matched its specs. It seemed to have all the headset adjustments and comfortability needed for a working from home environment. I unfortunately had return the item due to it not being compatible with my phone. I had no issues returning the device and the owners of the company were extremely easy to work with. Would highly recommend this product!

If your company have a policy to not use WiFi devices, then you will need to buy the cable to adapt this to your computer and phone connection. Which is 20 dollars more. Also, it comes with the headphone or earphone. Once I got the cable it was easier to connect the item and start using it in less than 10 minutes. I love to use these because It doesn't hurt my ears while wearing my prescription glasses like regular big headphones.
