I recently purchased the Logitech ClearChat Wireless USB Headset to use mainly with my MacBook Pro while traveling for business. I enjoy using Skype with video to chat with my family back home. I was especially excited to find a wireless headset of good quality and I purchased this item to give it a try. The output sound was great and the range was more than adequate for my needs (I haven’t tested the range boundaries yet). The battery life seems to be quite good also and since I would never continuously use the headphones for more than an hour or two. It is unlikely that I would ever reach the ceiling for battery life on the ClearChat Wireless.
The one disappointment was that the input quality on any Mac running 10.5.4 or greater would frequently garble and distort. I tested it on my Windows notebook and it worked fine. After reading posts on the Logitech forum I realized that something changed in the Mac OS and that the firmware on the USB dongle needed to be reflashed.
I contacted a Logitech rep on the forum and he responded the next day with a message letting me know he shipped me a replacement dongle. I received it several days later and now the Logitech ClearChat Wireless USB Headset works perfectly on my MacBook Pro!
