Found this pair at Target for $59.99
Panasonic RP-HTX7
They cover your ears, cancel the sound around you, come in white, green, and red, and have a range from 7 hz-22 khz. The way they adjust to fit your head are very easy and comfortable. They make everything sound (unbelievably) clear (I was using $15 head phones before [which worked] but because of their quality, I didn't know music/doses could become so clear)
I wanted to test them out, so I tried nitrous since it was short and never worked for me before (tried it 4+ times) and I did feel some effects (although it didn't make me want to try it again)
I would highly recommend them if you don't want to spend more than $60 and are looking for high quality, comfort, don't want to wait for them to be mailed to you, and good HZ range (and you can get it in white, green, or red like I said before... I got white)
