  3. Moose

    The components were delivered promptly and the headset was a breeze to hook-up.

  4. Storm

    Long story short, we had major compatibility issues with our phones and trying to get a wireless headset that worked well and with ease. Luckily, we ordered this one, and my employer is extremely satisfied. Based on his review to me (since it was for him), this headset gets 5 out of 5 stars from our office. Enjoy!

  5. Beth

    Plantronics has been the leader for so long, I had a wireless headset years ago and just ordered for my office, LOVE it!

  6. Bill

    Great headset, fast shipping and easy setup.

  14. Jon

    Recently replaced my trusty CS50 with the CS545-XD, and I couldn’t be happier with its performance. Easy to install, sound is great, and battery never quits. Well worth the cost.

  15. James B

    Purchased the Plaintronics CS545XD-XD. Directions were a TAD confusing. A call to their 800 number made everything right. VERY professional and courteous. Buy your Headset HERE, you will not be disappointed
