Can you give us a little more idea about what kind of sound you're looking for?
Here's some new language to learn.
After reading that, try and answer the following:
Preference for open-back or closed-back headphones (ie, isolation needed, or prefer as much sound stage as possible).
Analytical sound or warm/bassy sound preferred? Flat/neutral or would you prefer a bassy/warm sound?
Any preference for treble? Is it ok to be bright or do you want it to be dull or simply flat?
What is your source equipment, ie, are you using a sound card, or do you have external equipment that you're using (is this for PC, or something like xbox or ps3)?
Does your budget include the microphone, or are you willing to use your budget for the headphone and get a microphone separate? Does it have to be a headset or can it be a headphone + microphone?
Are you in the USA or where are you, to help us know what your $150 will be able to buy. Can you shop online in the USA?
I'd like to have as much sound stage as possible, i don't care very much about isolation.
Analytical sound. I want the sound realistic, i don't want much bass and i want a certain clarity. It's hard for me to say because i haven't tested many headphones yet, but anything that sounds better (maybe cheaper) than beats will work out for me.
About sound cards, i don't know anything about them. Are they related to my video card on the computer somehow? Well, I'd say i intend to use them on the computer and on PS3. It would be great if i could use them on mobile devices as well, like on MP3 players, IPods, etc.
I was planning on buying everything with the 150$ budget, but now it seems that i won't be getting what i want with that. So, if you suggest me just a pair of headphones, it would be great too, maybe the mic i could buy other time. And yes, it could be headphone + microphone instead of a heaset.
I live in Brazil, but soon there will be an opportunity to buy on the US. But if there is any reliable online store that ships internationally, i wouldn't mind in buying there.
Thanks a lot for the help, i've checked the new language. If you still need any better/more information, don't be afraid to ask.
Thanks, davidsh. I'm looking at this thread right now and i'm finding it useful.
