Hey, so I currently own a pair of AKG Q701s, which I use an Aune T1 amp to power. However, as a college student, these headphones are difficult to lug around when walking to classes and to the library when I'm studying, and I bet my neighbors in the library don't appreciate the amount of noise that leaks out of them
Since I've already spent a lot of money on my Q701s and the Aune T1 amp, I'm looking for a pair of cheap, portable headphones that I can use while I walk to class and study in the library during the day while I am on campus. I really enjoy the sound out of my Q701 setup, but I want a more fun set of headphones to use while I'm walking around campus and at the library. I've narrowed my choices to the Koss PortaPro, the Superlux HD681, Superlux HD688B, and Superlux HD 661. Additionally, is there any difference between the Superlux HD681, the Evo edition, and the HD681B? I'm also open to other suggestions, but I ideally want to keep my budget under $50.
I listen to a variety of genres of music, but I typically listen to hip-hop and electronic music. The type of hip-hop I listen to though has a jazzy feel to it, and examples of artists I listen to are Nujabes, Acro Jazz Laboratories, Gowe, and DJ Okawari. I also listen to R&B, jazz, blues, and some classical music too.
Although I did mention that I needed a portable set of headphones, I prefer a pair of semi-open headphones over closed headphones since I don't really like the isolated sound of closed headphones, which is also why all the headphones I listed are semi-open. I figured that a pair of semi-open would allow some airiness in the sound while not leaking as much. I also prefer around-the-ear or on-ear headphones rather than in-ear.
So, back to the original questions: could I get some advice about helping to select between the Koss PortaPro, the Superlux HD681, Superlux HD688B, and Superlux HD 661? Additionally, is there any difference between the Superlux HD681, the Evo edition, and the HD681B? I'm also open to other suggestions, but I ideally want to keep my budget under $50.
