PRINCETON UB-HS24W UniSerB 2.4GHz Wireless Headset I purchased this item new and used it only once because the microphone on my Bluetooth headphones couldn't be used with my company PC due to security restrictions. It served its purpose, but the size didn't fit me, so I'm putting it up for sale. It works without any problems. Also, since it has only been used once, there are no noticeable scratches or wear. However, please understand that it has been in someone's possession before, and I ask that you purchase it with that in mind. #WirelessHeadset #USBDongle #2.4GHz #Princeton
