I did not see the Hesh II.
Thanks for posting that |joker|. Can I ask what dap/amp you used to test out these cans? Those K550s definitely look pretty sweet. I am surprised though by your 'crap all around' comment on the Aviators though. I find that they sound better when amped but that's just my opinion. Besides the sound, I wish the build and isolation were better, especially for that price tag.
My usual Cowon J3. Regarding the Aviator, I thought the bass, while not nearly as exaggerated as with Skullcandy IEMs or Skullcushers/GIs, lacked depth, control, and texture (a case of 'one note' bass a-la Beats), the mids were plasticky, the treble lacked smoothness, and the presentation was rather flat (this very obvious in comparison to the Mix Master Mikes). The guy at the booth did mention that Skullcandy was re-tuning all of their products with a new sound engineer so maybe I got a 'new' Aviator.
I came to your topic to ask you some questions, I have the Pioneer SE-mj5 and I like their sound, of course, not technically the best that I have, but is the most "enjoyable", but I'm going to sell them because I can't use long time, they are too tight, so I want some similar sound (good bass, normal mid, great highs) but more comfortable.
Compared to the-mj5 and Sony MDR-XB700.
Which has more bass?
Which has more mid / high?
Which is more enjoyable?
Which sounds more clear?
I also thought about the models, Koss Pro DJ 100, Denon DN-HP700, actually also in several Audio Technica, but these are out of my price range, because in my country they cost twice as much.
Street Prices in my country.
Sony XB700 $105
Koss dj100 $100
Denon hp700 $147
Audio technica M50 $220 (far from my budget)
To use just for music.
Genres that I normally hear: Rock, Ambient, Full-on, Trance, some Pop, D&B, Metal.
If you have any other suggestions, will be more than welcome.
You probably don't want the DJ100 or the HP700 - they'll both have less bass than the Pioneers. If you like the Pioneers, you're probably looking for a moderately bass-heavy or maybe slightly v-shaped headphone. The XB700 won't have the treble emphasis you're used to and its bass is more soft and smooth than hard and punchy a-la MJ5. I don't know if you have any other options but a Denon D1100 (assuming it doesn't have too much bass for you) or maybe something from Ultrasone would be a better match for the MJ5's signature .
