Some back story, now. About 4 years ago, I bought my first "decent" headphones (Shure SRH-750DJ) after dozens of cheapos. I finally decided that I love music too much to settle for crap anymore. I paired those cans with a Fiio E5, and fell in love with the sound immediately. After a few short months, the Shure's broke, and I replaced them with Sony MDR-V700DJ's, which I still use to this day, along with the same E5. Fast forward to today, and I feel it's time to upgrade once again.
Until now, I've used an assortment of iPod's and Android phones to listen to my music, and I think it's time to invest in a proper PMP. After some research, I decided on the Fiio X3, however it's come to my attention that the X5 is just around the corner, so I'll be patient and go for that when it's available. I've looked into my other options from Cowan and the like, but feel like the X5 is exactly what I need.
So now come the cans... First and foremost, closed-back is important to me, so I won't consider anything less. As someone who does a lot of travelling, I can't disturb anyone nearby, plus I don't want to be disturbed by any other noises around me. After reading around these forums and other places online, I've compiled a list of the headphones I'm considering:
Audio Technica ATH-M50
Audio Technica ATH-A900x
Beyerdynamic DT770 Pro (80 ohms)
The M50's are currently my top choice. I can't help but have my doubts, though. I want a nice balance of bass, mids, and highs. I'm not what you'd call a basshead, but I do enjoy bass that's noticeable, yet not overly exaggerated. I did own a pair of Sony XB500's a few years ago, and those were too bass heavy for me. As someone who's going to listen to all sorts of genres, a balanced EQ is more important. I like a wide soundstage, and I realize closed-backs aren't the best choice for that, but I can live with the drawbacks that closed-back offer. At the end of the day, I want something that is enjoyable to listen to just about anything, and could also be comfortable for hours of listening.
I've learned that the other three models on my list are good alternatives to the M50's, so with everything else I've mentioned (especially when coupled with a Fiio X5), which direction should I go? I'm very interested in the A900x as well, from what I've read about them. How about other alternatives from Sennheiser or AKG? I'm really in a limbo over which cans to get. If I could try them all out first, that would be very helpful, but there aren't any retailers in my area that specialize in this kind of equipment. I'll leave it to you pros to provide your feedback. Thanks so much in advanced. I'll answer any questions that may help in your recommendations.
