I work as an online language teacher, and I had been looking for a wireless solution to make my 6 - 8 class hours per day as comfortable as possible. After trying some lame Bluetooth headsets, and researching a little about the CS50 USB Wireless Headset, I made what is probably the most intelligent decision I've made since I started teaching online five years ago. The CS50 is totally comfortable, I can walk all around my apartment without losing signal strength, my students hear me perfectly clear, and I can actually REPLACE the battery after its life cycle is done. What else can I ask for?I've only used the CS50 for a couple of months now, and my only problem is that I regret not having bought it before. Yes, it's not the cheapest solution around, but you definitely get what you pay for!
