100-190$ Audiophile Headphones

I'll toss in an unusual recommendation, the AKG k540s are around your price point iirc.  They got me back into the audiophile game after many years.  They're not perfect but they have a very engaging sound in almost all genres imo and have a sound signature that's pretty unique to others I've heard.  Only problem is they don't have great build quality / detachable cable though the sound is most important, especially if they're going to be for home use only.  They are also very light and comfortable for long periods of time (I wore them on a 10hr plane ride from Russia to NY with no problems) though I wish the ear pads were made of a nicer material.

Since I got back into headphones I've gone from the 540s to the LCD2s and a number of ones in between.  I still have a special place in my heart for my 540s, I'll never part with them.  It may be nostalgia at this point, but I swear they still have some great little quality about them.  They don't have great reviews and they're pretty unknown, but I love something about them.

People will tell you to get Grados for rock, but I think these are much more comfortable and they have a pretty forward presentation that works for rock.  Nice crisp treble and decent bass though the mids are a bit lacking.  I'd take them over a entry level Grado any day.  Again, they are just a great allrounder imo but the bad thing is I doubt you find anyone else to corroborate my experience since they are pretty uncommon.  It's up to you in the end, read reviews and pick what you like, but that's my 2 cents.  I always love to share my experience with these cans when I get the chance.

Jaycar Pro Monitor Headphones.

Closed back? Yup!
Neutral sounding? Let's just say that they're called the closed-back equivalent of the HD-600s for a reason.

No amp? Well...they benefit from one, but they can be driven from a phone or a tablet pretty well.

Gaming? Oh, they're a blast. I use them on my XBox all the time. They have a crazy-wide soundstage, especially for a closed can, so positional accuracy is top-notch.

Detachable cable? Yuppers! Replaceable ones are available at MP4Nation.com

Solid build quality? These things are built like TANKS.

and the kicker...

Under $190? Try $70 shipped from Australia.

But wait, how can a headphone so cheap be so good? Because it's completely identical to the $130 Brainwavs HM5 and the $199 Fischer Audio FA-003.

Huh? Yep. All of these headphones have the same drivers, the same carrying case, the same enclosure...but different brands and prices. They're all actually the Yoga CD880, Yoga being a company that manufacturers electronics to be bought by other companies and sold. Jaycar does it the cheapest, but if they're not available in your area, the Lindy Premium Hi-Fi (£73.51) is another version of the Yoga CD880, completely identical to all the rest of them.
