Plantronics CS50 Differences Compared To Plantronics CS55

Posted by Doug Merritt on Jul 1, 2016 2:02:09 PM

When considering a Plantronics CS55 wireless telephone headset, you may find yourself comparing it to its closest cousin, the Plantronics CS50.  So how are these near identical products the same and different?  Below you will find some information that will help you to sort out the differences.

Microphone

Both models have a noise cancelling microphone for removing unwanted, ambient room noise.  Having this feature is important if you want to establish and maintain a high quality phone call without annoying background noise.

Wearing Options

Both models come with a headband for over the head wearing as well as with ear loops for those who want an on ear wearing experience.  Early versions of the Plantronics CS50 came with two different types of headbands as well as ear loops.  Later versions of the CS50 came with one style of headband only.  So when comparing the later CS50 version to the Plantronics CS55, they’re the same in terms of the included accessories for wearing options.

Adjustments

The Plantronics CS55 has the ability to make adjustments to the listening volume as well as to the volume level of the microphone.  These exact same adjustments are found on the Plantronics CS50 as well.  The same applies with the headset mute button which are identical on both models.

Resets and Resubscriptions

When a reset or resubscription is needed, the manner in which these actions are performed are identical between these two models.

Battery

Though these two models use the exact same battery, the CS50 is rated to provide up to 8 hours of talk time.  On the other hand, the Plantronics CS55 is rated up to 10 hours of talk time.  If the batteries are the same and the headset essentially the same, you might be asking yourself why the difference in talk time?  The answer to this question lies in one key difference between these two models.  The Plantronics CS50 broadcasts on the Digital 900 MHz frequency where the Plantronics CS55 broadcasts on the Dect 6.0, 1.9 GHz band.  In the case of the Plantronics CS55, it consumes less power and therefore allows for longer talk time.

Wireless talk range

In spite of the fact that both headsets are rated up to 350 feet, you’ll find that the Plantronics CS50 tends to go further when compared to the Plantronics CS55.  Aside from the fact that these two headsets broadcast off of different frequencies, the CS50 has a taller base which supports a taller antenna.  This taller antenna allows for longer talk range when compared to the shorter, CS55.

Headset and base interchangeability. The Plantronics CS50 headset top cannot be paired to a Plantronics CS55 base.  Likewise, the CS55 earpiece cannot be paired to a CS50 base.  As mentioned earlier, each model operates from different frequencies which means that they cannot be interchanged.  Sometimes it’s hard to know the difference between the two.  Here are some quick tips on how you can tell them apart. 

The Plantronics CS50 base is taller than the CS55 base when placed side by side and if you look on the bottom of the base, it will have imprinting that indicates one or the other.

If you remove the battery door cover and slide out the battery, you will see imprinted on the white sticker which is adhered to the back of circuit board a designation.  This designation will indicate if the headset top is a CS55 or CS50.  Without viewing this, the headset tops look virtually identical when placed next to one another.

Discontinued

Both models have unfortunately been discontinued and improved with the new Plantronics CS540. If this is the style of headset your prefer, then check out our blog on the Plantronics CS50/CS55 compared to the new Discover D904

In summary, the main differences between the Plantronics CS50 and the Plantronics CS55 are:

  • The CS50 has a taller charging base when compared to the base of the CS55
  • The CS50 broadcasts on the Digital 900 MHz frequency
  • The CS55 broadcasts on the Dect 6.0, 1.9 GHz frequency
  • The CS50 battery provides 8 hours of talk time
  • The CS55 battery provides 10 hours of talk time
  • The CS50 has longer wireless range when compared to the CS55
