kaya nga i would like to stick with models na within the price range ng behringer headphones nya... IMO, its quite frustrating na ganito lang kaya mo and people around are raving about high end senns...
The HD280 is relatively affordable at $99. I even got mine for $79 when I was perusing through a computer catalog of all things (tigerdirect ata). Anyway, good as it was, I did not mix with the senns but I relied on them when I was cleaning up some audio. Their isolation allowed me to really concentrate on frequencies and other audio artifacts.
Here's the thing... we can say this brand is great or whatever, it's still up to the TS' choice on what's affordable. I started out with a Sony MDR-V600 'monitor' headphones which was great because it folded and I moved around a lot then so portability was very important. Problem with those cans were that they were supra-aural and having them on for 2 or 3 hrs non-stop was literally painful for my earlobes. That's why I chose to go circumaural since then.
I've used the budget AKG K66 before and it was ok but not great in the isolation department. Bleed is a common problem with loose fitting cans as well as open backs, that's why I recommended the HD280 if bleed control is an important consideration when choosing a headphone. Another contender are the Sony 7509's, but I can't find these at any Sony store. Same with the senns... ask for the HD280 and watch the salesguy give you a blank stare.
I presently use the AKG K240 Studio which at $99 won't break the bank, but is very good aurally, for me at least. I love the AKGs because they are very durable and sound great. I would like to try the AT ATH M40fs or M50, but Marvin Q recently let me on to his Samsons, which look very similar to my K240s, sound great, and at less than 2k, should be a steal as far as headphones go.
