I've been using the DC 10-13.4 for around fifteen years and am very happy with them. Other than adding gel-filled ear seals (foam-filled were standard when I bought mine) and cotton ear covers, they proved comfortable and reliable straight from the box.
The 10-13.4 is a marked improvement over earlier DC models in terms of comfort. I wear spectacles and used to find some older headsets less than comfortable yet have flown up to seven hours in a day with the 10-13.4 without discomfort.
No, I'm not on commission, nor do I have any connection with DC!
