hey i am new to this forum
i read a lot of pages of this awesome guide
I am from India and audio gear available here is quite pricey compared to US.
I am a laptop user and i play competiitive CS 1.6 at my college.
For Dolby audio i plan on buying Asus xonar U3.
But i cannot decide on headphones
My budget is restricted to headphones available around 50 $( more or less ) in US.
i finalised HD 201 but i have more money to buy better ones if available.
Please suggest me.
I don't know if you'll read this, but I would advise NOT to buy the HD201. I gifted a pair to my mom, but they were not comfortable for both of us, and the sound wasn't very special. They are available for like $15 in the USA... if that's your budget, you really have few options. The HD202 is worth the extra money, based on comfort alone. It was actually a fun headphone to listen to — though treble suffered from some distortion (and sound is overall not very refined), this is actually a very good sounding headphone among low-price options. I personally used a Sennheiser PX100 for about 6 years, and I was pretty happy with those. I still have them and they work well, but I need to replace the foam ear cushions, they have basically worn through.
Koss is another brand besides Sennheiser you should look into. Even their cheap earclip (Koss KSC75) and sporta-pro or porta-pro models sound good for the price, though the porta-pro may be out of your budget ($45 in the USA: http://www.amazon.com/Koss-PortaPro-Headphones-with-Case/dp/B00001P4ZH).
JVC is worth researching too. I liked the HA-RX900 (modded with a little pinch of cotton in the earcup to smooth the treble, and the earcup surface dampened with Dynamat to reduce resonance and make the bass more clean), which may also be out of your budget, but I've read good reviews about their on-ear portable headphones and their JVC Marshmallow in-ear buds.
