I had the 15XL for about 3 years bought the bose when I starting instructing. If you want a full size headset there is no comparison. The 15xl is good but the noise canceling isn't as good and its hot. It also clamps down on your head. I'm fixin to start flyin a jet for a regional and I'm probably gonna get a telex 750 or 850. The flight school that I work at also has a pretty good sized internet pilot shop and so I have used all different kinds of headsets and if you want a regular sized one that is good for small and big airplanes there is no comparison to the bose.

Put the money you'd spend on the Bose into a savings account. Suffer with your ANR till you get the job. Then use the D-Cs the company supplies with the plane. Be sure to also use the wipes the company also supplies with the plane. Send me half the intrest in ten years. ;)

Companies supply headsets? I'm unfortunately going to be forced to get new headsets. Or used ones, just new to me. I currently have the DC 20-10s. They are great headsets however while the ANR is good you can't hear anything when the battery dies. These are modified using the ANR upgrade you can order from Headsets INC. Just curious if it would be against rules to use them in the cockpit of a CRJ or ERJ since they aren't FAA approved.

I use Sennhausers(spelling) and they are money. Half the price of Bose, smaller in size, and you can't hear any outside noise when using the ANR, and when the batteries die and forget to change them, they are still excellent in keeping sound out.

Give it to you? I'll need it for a hearing aid.

Everyone has a different fit. I've tried headsets that people swore were incredibly comfortable only to get severe headaches. I used my Bose on an 18.5 hour round trip flight in a NOISY old 206 last summer and barely felt the things on my head.

How's the comfort and what type are they?

Is the lightspeed headset with boom mike (not sure on model) with customized ear molds adequate for the ERJ?

My thoughts exactly. Some think that ANR is a needless luxury...and there's no way to know whether or not that is true, to be sure. However, I do know that when I have flown with a non-ANR headset I have had to turn the radios up much higher to block out the aircraft noise, accelerating the harm to one's ears.

On the Lightspeeds...yes, they are cheaper. But I've often said that when I wore one I felt like I was wearing the Pope's hat in the cockpit, due to their size. After an hour and a half, my ears and the side of my head hurt...a lot...from the clamping. So, from my experience, their comfort, size, and noise reduction were all lacking in comparison with the Bose X. If you buy the Bose X, you will no doubt be able to borrow someone else's Lightspeed to try for a bit. If you like it, buy one, and sell your Bose for a great price...you wouldn't be out much.

As with all things in life, one has to do what's right for them. If at all possible, try several options, and go with what you deem to be the best.

Mach 1 is what you are thinking about. I tried it out for a month but didnt like having something in my ear. Years of using ear plugs will do that to you. Lightspeed worked with an exchange and I got the 30xl with the mp3 and phone adapter hook up and I love it. The phone adapter comes in handy when I need to call maintenance on a tight turn and dont want to take my headset off. Very comfortable and not much bigger than the bose. I like the bose but could not justify another $400 when this headset is just as good. I fly the CRJ-200 and I am more concerned with my long term hearing and comfort than how it messes up my hair. Lightspeed has superb customer service and great products.
