This is a set of three Phonak Roger Pen digital wireless hearing assistance systems. Purchased between 2016 and 2017, these have been used extensively for work. I am replacing them with a different model. These three units have been tested for charging and startup and were in use until recently. They are several years old, and the sound may be slightly weaker, and the battery life may be shorter. However, they are still usable, so rather than discarding them, I'm offering them for sale. I've included the 750 yen shipping and handling fee for Mercari delivery. Given their age, repairs would likely cost over 50,000 yen, so I do not recommend purchasing them with the expectation of repair. Please consider purchasing these with the understanding that their operation may be unstable, and consider it a bonus if they work, or if you are interested in disassembling them for parts. Those with hearing aids or cochlear implants will need a separate Roger receiver. Some Phonak hearing aids may not require a receiver, but other hearing aid receivers can cost around 100,000 yen. Please contact your dealer or Phonak for information about receivers. Not all accessories are included. Only what is shown in the photos is included. However, you can charge and use the Roger Pen with a standard micro-USB charger, which can also be used to charge mobile phones.
