Bluetooth Wireless Headsets
Lopresti recently introduced a product that I've long awaited --
bluetooth wireless ANR headphones. This technology seems to be key to solving one of the great aggravations in the cockpit -- wire snarl. I've done everything possible to minimize wiring from our GPS units, and from XM satellite radio -- but we've STILL got a massive snarl of wiring for our four- place intercom. To do away with all that, once and for all, would be awesome. Strangely, the product seems to have generated very little buzz in the market, and very little notice in the magazines, which is surprising to me. Perhaps it's because Lopresti is new to the headphone market? Anyone seen/tried these things yet? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Perhaps it's because Lopresti is new to the headphone market? I bet that's it. If Bose or Dave Clark came out with them, everyone would know about it. Anyone seen/tried these things yet? No. Where did you see it? What does it entail and what does it cost? |

Do a search for "Lopresti Headset" and you'll get gajillion hits. Here's one: http://www.sbwire.com/news/view/11896 -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Bluetooth Wireless Headsets
That's the link I just finished reading.
Sounds like a great idea. A few questions that immediately pop into my head a Are they ANR's? I missed that in the link. how big is the "wireless module that connects to your aircraft RCA jacks" (and where do I put it) Is the 8-10 hours on a charge for the 3v Lithium battery a real world number or is that without anybody talking? How many flights will I be forced to dig for the RCA cords and plug myself in because the battery just died? Most of us can carry on a conversation while ATC talks with other aircraft, keeping an ear perked for our N number or location. Although I know nothing about "cascading frequencies" I wonder if cockpit conversations as well as music will be totally cut off when ATC speaks. Looks like Christmas roll out once they find a headset partner. Someone else to add to my OSH list! Jim "Jay Honeck" wrote in message ups.com... No. Where did you see it?

Are they ANR's? I missed that in the link. In my opinion, the hot setup is a small box (cigarette package size) that clips to the back of your seat, your belt loop, or your shirt pocket and your CURRENT HEADSET plugs into that box. Two main advantages: One, it uses your expensive current headset in any format you desire AND if the "wireless module" goes TU, you take the headset plugs out of the module, break the wiretie cord, plug them into the aircraft jacks and you are back in business. While connected to the module, you can coil the headset cable up and tie it with rubber bands or thread that can be easily broken in the aforementioned TU mode of operation. I have just gotten my response from TI as to their recommendations for the technology (strangely enough, just started last Tuesday before I got wind of this nonsense) and their recommendation is to go straight ISM and not fool around with Bluetooth or Zigbee...this from their senior applications engineer. We are going to have a wireless unit by Christmas also, but I decline to state the year {;-) how big is the "wireless module that connects to your aircraft RCA jacks" (and where do I put it) Aircraft do not have RCA jacks with one exception and that is the antenna connection on a marker receiver in some makes and models. Some older transceivers used them on the NAV antenna as well, but nobody uses RCA for audio. Is the 8-10 hours on a charge for the 3v Lithium battery a real world number or is that without anybody talking? How many flights will I be forced to dig for the RCA cords and plug myself in because the battery just died? If we can get 50 hours on a 9 volt battery for a full 4-station intercom, I fail to see how a simple microwatt transceiver will only get 10 hours on a Lion battery. Most of us can carry on a conversation while ATC talks with other aircraft, keeping an ear perked for our N number or location. Although I know nothing about "cascading frequencies" I wonder if cockpit conversations as well as music will be totally cut off when ATC speaks. We did a hell of a lot of testing in-flight before we decided that the ONLY priority in the audio system should be to shut the music off whenever ANYTHING else (ATC, intercom, marker, alert, etc.) comes on. You should have control of everything else. Looks like Christmas roll out once they find a headset partner. Someone else to add to my OSH list! I'd volunteer, but I really don't like their design mechanisms ... it seems you have to have an Ipod on board, the priority system sucks, the battery life is nfg, and while Bluetooth is a great buzzword it really doesn't belong in this sort of a system. IMnsHO, of course. Jim |

around with Bluetooth or Zigbee What is ISM? (and what is zigbee?) Jose -- There are two kinds of people in the world. Those that just want to know what button to push, and those that want to know what happens when they push the button. for Email, make the obvious change in the address. |

That sounds like in intelligent solution. I suppose there'll have to be another little box to plug into the headset jacks. The audio portion seems relatively straightforward, but have you designed a robust method of keying the mic _only_ when intended, that won't be affected by stray transmissions? I have just gotten my response from TI as to their recommendations for the technology and their recommendation is to go straight ISM and not fool around with Bluetooth or Zigbee...this from their senior applications engineer. It's hard to argue with Motorola, but it would seem that with so many cell phones supporting BlueTooth now, the additional ability to communicate with the phone might be a plus. |

Here's one: http://www.sbwire.com/news/view/11896 The reason you haven't heard much about it is that it is so new it may not really exist yet. The press release you linked to above is dated 5/14/07 and the website mentioned at the bottom of the press release http://www.LoPrestiFury.com shows no information on it. |

To do away with all that, once and for all, would be awesome. I love Bluetooth - and went all BT in the cockpit to eliminate the cable tangles: BT GPS, BT XM Weather, BT Tablet PC. But there is no way I am going BT headset. I believe communications is something where the KISS rule applies. Jay - regarding your headset cable tangles - do you have a panel mount intercom? Or are you using a portable? I used to have a portable on the floor next to the flap handle (Cherokee) and always got tangled entering/exiting the plane. I installed a PS7000, put headset jacks in the lower corners of the panel, and in the rear - where the ashtrays used to be. It works great, and I cannot recall tripping on a cable since. OTOH, I typically do not fly with all 4 seats full as you and Mary do, so that probably makes a difference. -Nathan |
