   Digital telephone sound to bluetooth hearing aids, October 9, 2009

   This review is from: 500A Telephone Adapter (Electronics)

   I am hearing challenged and recently purchased new Oticon EPOQ hearing aids. They have an accessory streamer that allows you to connect via bluetooth to up to 8 devices; such as your cell phone, an ipod, television sound, etc. The streamer then routes the sound directly into the hearing aid. I purchased the Plantronics Voyager 500A to connect my multi-line digital work telephone via my streamer to my hearing aids. The Plantronics base unit is designed to be used in conjunction with a bluetooth headset, but it works well with my streamer to accomplish the same goal. Only problem is the base unit has a receiver to “charge” the headset which in my case I do not need. Sometimes the red indicator light on the base blinks for the headset to be recharged and it will not accept calls during this time. Therefore I just unplug the base unit each night and plug it back in in the morning. This circumvents the necessity of charging the headset, which I do not have.

   One of the few universal Blue-tooth adapters for an RJ9 connection., February 13, 2009

   I’ve been researching universal Blue-tooth adapters for office phones (mainly Polycom IP phones) for about a month now. The lack of information and products out there is astounding. Understandable though, it’s two new markets that are set to merge, they just haven’t done so yet. In my research I spoke to some of the leading headset experts in the office phone industry and they weren’t aware of a universal Blue-tooth solution to use consumer grade (cell phone) Blue-tooth headsets with an office PBX/IP phone. Anyway, I first bought a Scala combo kit which includes a Scala-500 Blue-tooth headset and BTA II universal Blue-tooth adapter. The adapter connects to a device via 2.5mm male connector. The problem is that most office phones don’t have that type of connector, they have an RJ9 which is the small style telephone plug. Although a patent exists for a female 2.5mm jack to male RJ9 plug, the device simply doesn’t exist in the marketplace for purchase. Eager to test this 2.5mm to RJ9 connection theory I went to Radio Shack and bought some parts, put together an adapter and we have success! The downside is that we would have to get the part manufactured and it’s still a bit of a hack. Long story short, decided to test the Plantronic Voyager 500A to see if the base was proprietary to the headset like most of the Bluetooth office headsets out there. My gamble paid off and it looks to be truly universal. Of the headsets I tested with, all pick up and hang up the call remotely EXCEPT the Jawbone II. Why this doesn’t work to pick up the call i’m not sure. It hangs it up just fine.

   Headsets tested with success:
   – Scala-500
   – Aliph Jawbone
   – Aliph Jawbone II
   – Motorola
   – BluAnt Z9i
