  1. Love them! Review by Chris

    We have been using these headsets for years in the high-call volume areas of our office. They are very dependable, and Plantronics' support has been super in assisting us with settings to improve call quality.

  2. Excellent service, pricing and features. Review by Christmas Carol

    I thought this was a great price - excellent selection of various types of ear pieces - my ears seem sensitive, so I really appreciated having the large foam-style earpiece. Fast shipping service and easy to use equipment.

  3. Fantastic Purchase Review by purplesonic

    My CSR's love their headsets. They are clear and easy to install and use.

  7. good Review by sheryl

    We like the product but it has an echo when phone is in use. There weren't instructions about changing a setup item on the phone.

  8. Most comfortable headset Review by KimD

    This is the most comfortable style headset I have found. This makes talking on the phone all day much easier, especially with the handset lifter.

  9. Excellent Review by Hazel

    Sound quality and range is great with this headset.

The Plantronics CS50 Wireless 900MHz Office Headset System brings the ultimate in mobility and sound quality for hands-free conversations to your phone. Totally wireless, the Plantronics CS50 gives you up to eight hours talk time and the cordless convenience to roam up to 300 feet while having secure conversations. The headset continuously charges in the cradle, and when in use, taking or ending a call is as simple as pressing a button. Compatible with typical office or PBX-based phones, the headsets can be worn on either ear or over-the-head for maximum, long wearing comfort.

1-Year Warranty     1-Year Warranty     


The Plantronics CS50 wireless headset system combines the clarity of traditional corded technology with the mobility of wireless, so you can move around the office to wherever business takes them — without interrupting or missing a call. 

          + Mobile Multi-tasking
          + Noise-Canceling Microphone
          + Up to 8 Hours of Talk Time 



Conferring with colleagues, walking to the printer, pouring a cup of coffee— need not interrupt important calls up to 300 feet from a desk phone.  With Plantronics, you simply get more done as you're able to continue talking while tackling other tasks throughout your office.  Spend the time you're on hold being productive, as you organize your files, clean your desk or tidy up your credenza.



An extended boom and noise-canceling microphone filter out background sounds for heightened speech clarity.  This allows your call to hear you and not the noise within your office.  With the superior noise-canceling technology you will repeat less information to your caller and it will be more accurate which eliminates errors and call-backs.




Using an optional HL10 handset lifter or compatible EHS cable adds the convenience of one touch answering and ending calls while away from your desk.  More importantly this keeps you from missing calls when away from your desk.  When your phone rings, the HL10 or EHS cable will send a signal to your CS50 which alerts you that your phone is ringing.  With the push of a button on the headset you can answer the call and avoid playing phone tag with your clients.



As you walk away from the base unit you will eventually reach the system operating range limit. When in headset mode a warning alert of two beeps will sound in the headset shortly before you meet the range limit. On hearing this alert you should walk closer to the base unit to ensure call quality is maintained. If you remain out of range for more than 15 minutes the system will drop the call permanently.



When the headset battery is running low (approximately 5 minutes talk time remaining), an audible warning will be heard through the headset as a single beep repeating every 10 seconds. Soon after hearing this warning, you should recharge the headset.

• One beep in the CS50 headset every 10 seconds is caused by a low battery warning.

• Two beeps is an out of range warning. Move the CS50 headset closer to the base.

• Three rapid beeps every 15 seconds indicates your CS50 headset mute is on. Press the mute control dial once to turn mute off.

• When an optional lifter is connected, three repetitive beeps indicate a call is coming into the headset.
