SR325x

Grado SR325x I know its not exactly what you want but its probably for the best if you get some high quality open backs, open backs would be better if your like going on walks, getting groceries or doing things around the house or just a place you should kind of be attentive to around you, the Grado SR325x would be great for that, theres high quality, good build and you could even use them for studio listening, they are extremely portable seconded to iems and wireless headphones, and i also see lots of people buying them to use with walkmans. But Rode NTH-100 If you really want closed ear noise damping portable headphones, the Rode NTH-100 would also work, ive read reviews and it looks like they leak audio quite a lot but if you want the feel of fully over the ear headphone they look great for the price

I've used several Sennheisers and I second/third/fourth the HD 490 suggestions in this thread. They're slightly bassier and more exciting than the HD600-series, and *very* comfortable. If you like the open-back sound I also suggest you try something Grado, for example the SR325x is in your price range and very good. I know they're not for everybody, plenty of people don't like their sound. But also plenty of people *do*, so I recommend you try them as they may just be your jam.

I've tried for years to like the HD600s including forcing myself to listen only to them and nothing else for a month. Still no go. I liked the HD800s just fine. But I love Grados. I have the RS1i, RS1x, 325x and original GS1000s. I like them all better than either of the Sennheisers.

Grado 325x will be good

Grado SR325x puts Sennheiser to shame. You will be amazed at the soundstage (3D sound). Unbeatable sonic value for games, movies, and music.

I love my Grados. Had SR60s in high school and finally upgraded to the 325x last summer. I work in music production so I just use my UAD Apollo as headphone amp.

I use Grado 325x pretty good for most styles of music but they excel at rock
