Sennheiser OfficeRunner D.E.C.T 6.0 Headset

Certified Refurbished

The Sennheiser Office Runner is a top of the line wireless headset that is compatible with both Yealink and Polycom phones, in addition to 98% of all corded office phones. This headset has a range of up to 400 feet, and is capable of 12 hours of talk time on just a one hour charge.  It also is convertible, offering two different wearing styles, and has a noise cancelling microphone.

With the OfficeRunner, you'll be able to talk comfortably up to 590 feet away from your phone. Plus, you'll have the satisfaction of knowing that your voice is coming through clearly to your callers thanks to the built-in noise-canceling microphone.

This headset works with 98% of all corded office phones.

Not only does the OfficeRunner work with your office phone, it also works with your computer right out of the box. The OfficeRunner is certified for use with softphones from Cisco, Avaya, Microsoft, and others. It also works with popular VoIP services like Skype and Google Voice, and you can even listen to music between calls!

Looking to answer remotely from up to 590 feet? You'll need one of two accessories we offer: the ORL12 handset lifter or one of the direct-connect cables we offer (available for specific phone models only). Both options also offer Ring Notification, which alerts you to new incoming phone calls if you've stepped away from your phone. Never miss a call again with the OfficeRunner.
