Plantronics CS55 Micro Wireless Convertible Headset
I have used Plantronics products for several years and have never had a problem. I expect longevity with this purchase.

The design is nice; however, the unit kept falling out of my ear, despite choosing the smaller ear wrap that hurt my head and ear. So I opted to use this with the over-the-head piece and the comfort level went up. The sound quality is very poor. I have to turn the volume way up to hear anyone and then turn it down when I talk so that the caller doesn’t feel screamed at. Not to mention the fact that if I have to type while the caller is talking, I and the caller can hear every keystroke in the earpiece. It is so annoying. I am returning it today.

Plantronics CS55 Micro Wireless Convertible Headset
The headsets are working great, the order process was friendly and efficient, and the follow up with a thank you was much appreciated. I just went through a terrible experience with Best Buy, and made me realize that there still is great customer service out there. Thank you so much for making the process actually enjoyable!

Plantronics CS55 Micro Wireless Convertible Headset
We bought the CS55 Micro thinking that we'd get different wearing styles than the CS55 had, but were disappointed to find they were the same. From the CS55 Micro product pictures, we thought that the earloop was going to be like the Bluetooth earloops, that we find very comfortable. Most of us cannot wear the CS55 Micro earloop longer than a couple of hours before it becomes too uncomfortable to wear. I'm surprised that Plantronics hasn't improved this feature.

I have had my Plantronics Micro CS55 unit for almost a week. It allows me to carry on business away from my desk while allowing personal telephone service. It has great range and I am very impressed. It was very easy to install and the longest part was waiting for the headset to charge!!

I work in a call center and use a headset 9-10 hours a day, 6 days a week. What's important to me in a headset is: all day comfort, lightweight, and reliability. The CS55 Micro is #1 in all those categories. It’s been a pleasure to use and is very affordable. The freedom in the office it gives me is the greatest. The support from the Customer Service Experts at is the best and is what keeps us coming back time after time.

Customer Service / CS55 Micro
I bought the Plantronics CS55 Micro. I had another model prior to this one, but it was too bulky.(Returning it was not an issue at all, smooth transaction) The Micro is much better. It's not as heavy on my ear. I can hear great on it & everyone that I talk to says they can hear me just fine. The only thing I wish it had was a flag for me to put up to let people know when I am on the phone, as the headset is hidden by my hair.

Instructions for the Micro are very easy to understand and has excellent Customer service to help in adjusting all of the features for the headset. has an online chat Customer service option that I found very helpful in researching the headset that I needed and to make my return. I would definitely use & recommend again.
