    These adapters work great and Headsets Direct got them here on time.

  2. Scot

    I think Plantronics is an amazing company with great products. I tried a couple times to use the DA70 USB adapter plugged into my computer. I wanted to use it while on Skype or similar VOIP connections, listen to a video on YouTube, what ever. The two times I tried it, it logged me off of my computer without me ever getting connected to anything. I have so much faith in Plantronics, I can only imagine it is user error on my part. Probably because I am old and retarded. I don’t expect you to post my review. And I still love you! I will call tech support and learn how to use my DA70. I’m sure it’s great and I just need to learn how to use it properly. Merry Christmas to you all at Plantronics. Happy New Year! And ….. “God Bless Us! ….. EVERYONE!” 🙂

    Plantronics DA70 is exactly what we needed. Our order was correct and arrived very quickly. We always use Plantronics equipment.

    I had a Pantronics headset for my phone – and then needed one for long video conference meetings. Headset Direct answered my emailed question immediately when I asked if there was an adapter I could connect to my computer. It worked really well and made the meetings much easier to handle. Fast service and knowledgeable reps.
