Jsta22 Posted June 6, 2010 Report Share Posted June 6, 2010 recently acquired (purchased) a supposedly new and never used before Bose X headset(single plug type for helis). Guy assured me up and down they were perfect condition , never used.. I plug em into the R22 when i got em, and I can hear tower, radios, and passenger just fine, But not my own voice, nor can they hear my voice. The radio pick up doesn't even register when i talk, and Ive had the VOX knob all the way up!! I had my daughter in with me on the ground with just the master switch on, and she can slightly hear me when i slightly depress the talk trigger, or she presses the cabin button by her left foot, but other than that, Nothing coming from my Mic when I talk.. I have new Duracell batteries in it, and volume all the way up..Any Ideas?Appreciate the help.. Of course the guy is not responding to my emails!!Joe Quote Link to comment Share on other sites More sharing options...

There is a chance, if the set is new, that he bought it from a vendor that buys mics and headsets separately and they sent you the wrong impedance mic.. that happened to me when i bought mine. what ever it is i would expect you to be able to get it working just fine.. good luck, dp Quote Link to comment Share on other sites More sharing options...
klmmarine Posted June 6, 2010 Report Share Posted June 6, 2010 There might not be anything wrong with your headset. In some R22s (esp early ones) there is a wiring issue that sometimes causes problems with Bose Headsets. I had a similar problem when I started using my Bose and I finally had to get another headset until I switched aircraft. I haven't had a problem since. My recommendation is, try to find another aircraft to plug into and try. If it still doesn't work, call Bose tech support and ask for help. They are usually pretty good about customer service.

BOATFIXERGUY Posted June 6, 2010 Report Share Posted June 6, 2010 Also check the DIP switches inside the battery box. One or more might be set wrong. I got a set this way once. The settings are in your manual that came with it, or you can download one from their website. Quote Link to comment Share on other sites More sharing options...
AStarB3 Posted June 6, 2010 Report Share Posted June 6, 2010 (edited) take the mic off and make sure none of the connectors are bent. My bose had no sound on the second flight ever because the mic was loose........ tightened the screws and it worked fine. By "the mic I mean the entire assembly" Edited June 6, 2010 by mattkreps Quote Link to comment Share on other sites More sharing options...
TomPPL Posted June 6, 2010 Report Share Posted June 6, 2010 This sounds like exactly what happened to me. It's a problem with the avionics in the heli and not the headset. The school I use has 4 helis, I can only use my BOSE headset in two of them. Quote Link to comment Share on other sites More sharing options...
Pohi Posted June 7, 2010 Report Share Posted June 7, 2010 I had the same problem with one of my Bose headsets that was supposed to work fine when I bought it. I swapped the mike with another one to determine that the mike was bad, then called Bose. They had me read the serial number off of the headset to verify that it was still under warranty (I told them, and they did not care that I was not the original owner). I had the new mike within a two or three days at no cost. Quote Link to comment Share on other sites More sharing options...

Jsta22 Posted June 9, 2010 Author Report Share Posted June 9, 2010 Thanks for the help guys! Upon speaking with Bose, They say that its not a broken headset, Its the type mic i got.. I got a dynamic (Low impedance) mic. I need for Robinsons at least, a High Impedance Mic. $195 charge! I may just sell my headset and look for a used one with the mic i need, Unless someone has a High Impedance (Electret) mic they wanna sell me cheap????I'm open!! Let me know1 Quote Link to comment Share on other sites More sharing options...

gft Posted June 9, 2010 Report Share Posted June 9, 2010 I had the same problem.....I sent them to Bose, they changed to different impedencemic, no charge. Tell them ahead of time that you're using them in a Robinson. Bose has a great service department. happy flying Quote Link to comment Share on other sites More sharing options...
HelliBoy Posted June 9, 2010 Report Share Posted June 9, 2010 I have a similar problem in a 300 I own, my bose will only play nice with annother bose, not DCs tho. If anyone knows how to fix this I'd be eternally greatful. My avionics shop has no clue. Quote Link to comment Share on other sites More sharing options...
amphibpilot Posted June 11, 2010 Report Share Posted June 11, 2010 I have a similar problem in a 300 I own, my bose will only play nice with annother bose, not DCs tho. If anyone knows how to fix this I'd be eternally greatful. My avionics shop has no clue. Don't know your H269 (H300) vintage but if the problem only occurs during "hot mic" operations (both mic circuits active) then suspect a microphone bias level issue due to non-RTCA DO-170 compliant circuitry. I often encountered this in R22's with Hot Mic switches and always ensured both occupants had the same make & model headset (problem was eliminated when VOX intercoms became standard on the R22, effectively allowing each microphone to have its own bias level).
