I used a Flightcom 4DX (their cheapie model) for a long time. I put Oregon Aero hush kits, headbands and temperfoam earseals on all my headsets, including that one. It's been through 180 degree cockpits day in and day out, freezing weather, wet weather, and all kinds of abuse in all kinds of operations, without any problem. Just as good on sound, just as good a mic, as most of the more expensive headsets.
We had a lot of folks at one time that put in the add-on ANR modules, but all took them out and went with the Oregon Aero treatment. It runs about a hundred bucks a headset, and is worth it.
Right now I use a Telex Airman Pro (or something like that). It's lightweight, and after running around with a plantronics single ear headset for a while, I finally admitted that I just don't hear when sound is only going in one ear. I can go all day with this little telex. It's light and comfortable, and does the job.
When I'm in something that requies a headsqueezer, mostly I wear a lightspeed. I don't have the newfangled gear, but an older one that does just fine. My biggest complaint in light airplanes is that I can't hear the engine as much as I'd like (I don't hear anything as much as I'd like these days). Either that, or the Flightcom cheapie.
I first got the lightspeed as a refurbished unit that they were making available to flight instructors. They gave a great deal on it, all you had to do was provide a copy of a flight instructor certificate. I had it about a week and it was wonderful at reduced power settings. I was flying an airplane that's probably one of the loudest to ever fly, and that headset just couldn't keep up at takeoff power settings. But once the power was reduced after takeoff, it was bearable, and for the first time I could talk over the ICS instead of using hand signals. (Is still use them today, even in a quiet cockpit. I realize it looks spastic, but old habits die hard).
I'd had the lightspeed for about a week. I was doing a departure into low IFR, and just after entering the cloud, the headband broke and it fell off my head. It's plastic, and it just fell apart. I plucked some electrical tape out of my flightsuit, and did a very hasty repair. A couple of months later I was in the same neck of the woods and the right earcup quit working. I took it to an avionics shop, and they fedexed it to lightspeed. All it cost me was the shipping one way. It was gone a day, and they fedexed it right back. Even though it was refurbished, it came with new earseals, a new headband, new power cord, new battery module, the works. Just like brand new, and they treated it as though I'd bought it new.
I was quite impressed with the comfort, cost, and performance.
Presently in my HGU55P helmet, I have a generic electret mic and standard avionics. I replaced the earcup earseals with Oregon aero, and requested a liner made from the same material, covered in leather. It makes a BIG difference on a hot day in a hot cockpit getting slammed around against the canopy. At least the helmet fits, and doesn't burn like some do. I can hear just fine, and I'm told the transmission off that mic is crystal clear.
I guess the point there is that I've always been quite satisfied with most of the stock products. Weather it's flightcom or avcom or any of the others, they're all about the same and the only real diffeence is how comfortable you want to make it. The only product for that, as far as I'm concerned, is the Oregon Aero products. I had thought about getting ANR in the helmet, but it's quiet enough, comfortable enough, and works well enough with standard generic gear that I'm not going to mess with it.
