Plantronics Encore binaural phone headset with Vista M12 amplifier.  Comes in the original box with instruction booklet, unused registration card and parts list.  Power cable not included.  Has a volume dial and dedicated buttons for microphone use and mute.  Worked great the last time I used it at the office, about 15 years ago, and has been in storage ever since.  Should still work with modern desk phones, but I no longer have a landline to test it.  Sold as-is, no guarantees.

Free shipping anywhere within the U.S.  International shipping will vary by destination; please ask if interested.

I welcome lower offers, especially if you are buying multiple items at once.  To make a lower offer, add the item(s) to your cart and on the checkout page you will be given the option to name your own price.  (If you are not seeing this option, it may be because your state requires sales tax.  Bonanza is working on a fix for this issue, but you can also send me a direct message with your offer.)  Full information about making offers here.
