I realize this may have already been discussed, but like many of you I have countless pairs of old wired headphones with nicely padded ear cups that I wanted to use with by Baofeng and Quansheng radios with the K-style connector. As we know the standard headphone jack is 3.5mm, but the HT's use the 2.5mm jack. For $0.59 cents each (not a typo) I just picked up a couple of 2.5mm to 3.5 mm adapters at Monoprice. https://www.monoprice.com/product?p_id=7124
Note that for certain HT's it's best if you don't fully insert the adapter, otherwise you may only get mono. So I just pull the adapter slightly out of the socket, and I was able to get full quality sound to both sides of my headset. I already bought a pair of headphones with a boom mic with the K style connector, priced at $50 and above) but in my opinion the sound quality is superior with the old-style headphones. Just wanted to share this with the Radio Reference community.
