This is my first time posting, and I was hoping to get some advice for a home setup. I hope this post isn't too long, I have tried to organize it well. I have done my research, and I am leaning towards the Beyerdynamic DT880 250 Ohm with an O2 amp.
My PC, either the motherboard/front panel or my Logitec G110 keyboard, depending on what works best. I have been working on gathering my music in flac, but I do have some low quality music, 127 kbps, not as important, I am working to replace them, but I would be interested to know if something would sound bad enough to need to switch to my old headphones for these or YouTube videos.
I currently am using the Bose AE2 for at home, and the MEElectronics A151 IEMs for travel and noise isolation when I need them. I actually like the A151s better than my Bose, but they irritate the inside of my ear after a while. I am looking for something that will be a large and noticeable step up to the Bose.
I listen to Jazz, my favorite artists being Christ Potter and the Maria Schneider Jazz Orchestra. I have never liked vocals very much, so they are not important. I love the sound of saxophone (I play tenor myself), so I would rank that as most important, if it matters at all.
Isolation does not matter to me. I current have a roommate, but he has his own headphones (ATH-M50) and says he does not mind if I have open headphones. He does have a mechanical keyboard though, but I do not see this being a problem, and I will graduate and move out by the summer anyways.
I have considered other headphones listed below. I am mostly concerned that the information I found by searching the forums of this site are outdated. I did not see any newer headphones in this price range that seemed like they were worth it. I also do not have a way to try these out before I buy, I am planning on buying these through amazon and checking the return policy, as it seems like it is easy to return to amazon. I did go to CES and tried on some Beyerdynamics, a different model, but I think the fit is generally the same across them, and they were really comfortable.
Sennheiser 600's (These are a bit pricey, and I am hesitant to spend that much if I don’t know if I will love them)
Audio Technica ATH-AD900X (Or maybe A900X?)
AKG Q701 (or K702)
These ones I am more unsure about but I looked at them:
Beyerdynamic Custom One Pro'
NAD Electronics VISO HP50
I don't know anything about amp matching with the others, I am not quite sure how that works. I feel like if an amp can drive a pair of headphones adequately, then a similar impedance headphones would work the same. I am guessing this has something to do with the frequency response of the amp and headphones not actually being flat?
Thanks for any advice!
