Bought the a Telex 850 and returned them after 1 trip. Bought the DC's next. MUCH better. They work great. I have had 2 planes where I got some loud feedback when I tried to transmit. My FO had the Bose/Uflymike on the last plane this happened on and I swapped headsets with him and sure enough, I could transmit with his just fine so it wasn't a radio issue per se. But 99% of the time the DC's work very well.

Took a black Sharpie to that light.....no prob now....I have had a couple of issues with uflymike and clarity.....Went away when the fo unplugged their headsets.....2 1/2 yrs with no problems......batteries last so long I forget about them and the headset is quiet when it is depowered anyway

Can anyone compare the DC Pro to the QC-15?

I used some electrical tape over them, the Sharpie idea is good too.

I am currently using Lightspeed Zulu 2's (not in a 737 but a E175 which is also loud) and I switched to the Energizer rechargeable batteries about a year and a half ago. I carry the charging pack along with me. Batteries usually last at least 2 weeks worth of flying. Best $20 I ever spent.

Have had/used my Ufly for 8 years now. Swapped the old QC's for the new one at SEA-TAC, cost $100. But my Ufly has been perfect. Used in Lear, KA350, 737-4,7,8,9, A320, B-757/767 and not an issue w/ any. When I get closer to the panel it makes a louder buzz, but other than that no issues. Will continue until it dies then look @ DC. Wish Bose would make a true lightweight set.

Baja.

BTW - What are people using in the PuppyDog? Is it as quiet as the 88/90?

I've used the Telex 850 ANR for nearly 10 years now in an Airbus and now 757. It doesn't use batteries, it gets its ANR power from the normal plugs.

I don't know how much louder a 737 is than a 757 but I would think it would work fine.

Is it as quiet as a Bose + the u-fly mic? Nope. Absolutely not. But I found the whole u-fly setup horrible when in the right seat (I'm sure it would work better in the left)

I've also used the non ANR Telex 850. It pretty much sucks. There is a big difference between the perceived quietness between the two models. But even so, I nearly always ditch the headset above 18

Just finished my first trip with my new DC PRO-X headset (I have been using an old school DC headset up until now). I flew a 400 several legs as well as an 800. I like the PRO-X, lightweight and nice sound. I will get a little piece of electrical tape to cover the light, as well as a clip to attach the cord so it doesn't just hang down, putting weight on the plugs.
