List,

  

 I finally took the plunge and bought the Thirty 3G  Lightspeeds. The day after they arrived I used them in the corporate jet that I  fly. They worked beautifully and because the jet has Bose headsets, I was able  to do a back to back comparison, which BTW, seemed to be about even on all  points. Anyway, here's the problem. When I use the Lightspeeds in my  RV-8, I get a squeal in the interphone when the volume is turned up past a point  where I can hear the back seater. If the volume is low enough, it goes away but  so does my ability to hear my passenger. I don't think it's feedback. It sounds  more like it's related to the VOX threshold. Once the threshold is crossed and  the volume is too high, it squeals. Turn the volume down, the VOX clips off and  the squeal stops. If I put the LS's in the rear and my "cheapos" in the front,  the LS's work fine. I tried the Bose in the RV and they work beautifully in the  front or rear. Until now (60 hours) my two cheepos have worked  fine.

  

 I've talked to the techs a LS and they have no  idea. They seem to think it's my airplane...but why does brand "B" (and my  cheepos) work in my plane and theirs does not?

  

 I also talked to the guys in the avionics shop at  work. They think it could be a mismatch between the LS's (stereo) and my  cheepos. (mono)

  

 My next step is to try two stereo sets and see if  that's the problem but in the meantime any ideas  from you guys would be appreciated.

Steve, since it appears from your post that you are just listening as you crank up the volume to get the squeal, alternately unplug the mic from the pilot then passenger and see if the squeal goes away.  A very sensitive mic can (and will) pick up the sound in the headset ..... nand viola .... feedback.  I may be blowing smoke here as it's a WAG, but try it anyway.  Another excuse to take someone flying!!!  Cure can be as simple as a second foam cover on the mic.

three prongs to match the three sections of a stereo headset.  Not sure

how this works but worth checking.

On this subject has anyone found a good "no headband" headset for the RVs? 

I don't have much headroom in the RV4 so I bought a Panther headset that 

uses custom earmolds.  The headset fits perfect and is Sooo comfortable, on 

the ground it works great, but above 1500rpm and the mic feeds all the noise 

to the intercom and radio.  The earmolds block out as much noise as our 

Telex ANR and Bose ANR, but since the mic is useless I need another 

solution.  I have been fighting with it since May and just today sent it 

back again this time with a recording of different headsets vs. theirs.  I 

expect I will be getting a refund and will try something else.  I was 

impressed with the ClarityAloft headset at Oshkosh, but it was not in an 

aircraft.  I would have been impressed with the Panther on the ground.  Any 

advise would be appreciated.



Thanks,

Mike

I'm really happy with my Aurricom set. The only complaint I can think of is that during the test phase (experimental engine... little bit of tweaking) I was in & out often and hands would get a little dirty and soon you would have an ear piece that you really didn't want to put back in your ear. Fortunatly they come with spare foam ear-pieces. Custom earmolds are also an option, but I've not found that I needed them. I must admit that I was a new pilot at the time, so didn't have any bias toward conventional headsets as I'd only had a few hours using them.

I like  my Clarity, takes more time to get on and sometimes bothers my ears.  Pressure changes from altitude can also be a slight anoyance. The  mic and sound quality are the best I've ever seen.  My Bose X is  easier to put on and about the same noise cancelling but heavier and messes up  the little bit of hair that I have. Both have their + & - and either make a  great choice.

I bought a $700 pair of Telex's the Stratus 50D's, they had a hiss.  

Sent those back got the Bose, which are pretty good, but don't have 

enough passive attentuation in my opinion, they let more high 

frequencies through than they should.

I chose Peltor because of the thin headband top.  I have been  

satisfied with it.
