Basic/mid fi headphone advice.

The ATH-M50X  gets a hearty recommendation from myself as well, nice call Al.
I have a pair that I bought on ebay for $119 shipped as an open box item but complete and unused and you do see them on ebay at times for even less new.
I find them light and comfortable and precise enough to enjoy my music at any time.
I also have a pair of Audeze el8 open backs and the wife will come in and complain that I may as well play music through the speakers!
An exaggeration for sure but I get her meaning.
I also have a pair of Klipsch earbuds that I still use for about 50% of my non speaker listening simply because they are the most comfortable buds I have ever tried and I usually hate buds to be honest. The sq is honestly quite something for such a tiny pair of drivers!
Just some thoughts......

The 2 AKG 's I mentioned he K175 and K182 were because they are closed and close to the price which the OP seemed to want or I would have mentioned the K240. I have the K701  semi open and have enjoyed  them for about 10 years. The only piece of equipment I own that's older is a panamax line conditioner/ surge protector. 

Thanks guys. All very helpful thoughts and observations. That's why I keep coming back here with my new-audiophile questions. Will let you know what I finally do. But it seems clear, for my purposes and for my wife I need to go with closed phones.

I settled for the  Sony MDR-7506s. They sound pretty good to me and came with free overnight shipping. For the price I think they fit my needs very well. Thanks for the good advice.

Like I said, you should have went with the modern retros.
