I travel a lot on planes. I also happen to record lectures for a living, so I spend a lot of time with headphones on.
My biggest complaint has always been comfort. Over, on, or in the ear, every headphone I have used hurts in some way after an hour or two.
My next biggest complaint is sound blocking. While trying to watch a movie on a plane, I end up holding the phones against my ears with my hands to block out the noise. That gets old pretty quick.
Now I have noticed that the community here is pretty anti beats by dre, but I have to say that the pro pair I tried on recently felt very comfortable and the construction was very solid. I also noticed that the noise around me disappeared entirely. Also, they are built like a tank; I bet they could stop a bullet.
However, I see a lot of people saying to go for the ATH-M50 instead. I'm interested. They seem better in every way except construction (molded cable and all plastic parts).
So, I'm hesitant about the beats for only a few reasons. First is that they are bass heavy (would you really expect something different from a rap/hip-hop artist). I am going to be spending most of my time watching movies and editing lectures. Bass heavy mixing is not a good thing for either situation. The next reason is their iconic nature. Just like Apple products, they are more likely to be stolen.
I'm hesitant about the M50 because I have not tried it and have read conflicting reviews on their comfort. I mean, the beats really fit quite naturally on my head. Also, I have some experience with audio technica stuff and was not impressed (granted, it was a completely different thing, a wireless mic and receiver).
So I want evenly distributed audio, comfort for hours of wearing, durability, and noise blocking (not cancellation because that takes batteries and produces an audible hiss which is very annoying during the serious and quiet dialogue of a movie).
Price point: I have a bunch of mileage points on United and I can buy gift cards in $100 increments from various stores, including amazon. I can also by the beats pro outright and the conversion from points to dollars makes them about $311; quite cheaper than I see anywhere else. The other brands available are Skullcandy, bose, Tumi by monster, sony premium, and Klipsch image one II. So pretty much any thing $400 or less on amazon, I'm interested in. I see the ATH-M50 is only $135 new on amazon.
