A lot of my friends have always recommended the Steelseries Siberia V2. I don't have any personal experience with them, but a quick look at reviews shows me a great pair of headphones at a good price, lower than your limit aswell. I suggest you look them up and check a review or two!
I'm using the Siberia too. Had several "pro"sets before from qpad and beyerdynamic and all that stuff but they are falling apart like the cheaper ones. The Siberia is pretty nice to wear and you don't get problems like hotears or aching ears even if you do a looong day in front of your pc. And as AngryCoco said, the price is nice ;-).
I'm using SteelSeries Siberia V2. I've even payed some extra for Diablo3 themed ones.
It cost me around 100 EUR. Bought when Diablo3 launched. Never had any issue with it, mic input is strong enough so i don't even have it 'pulled out' - it's always retracted in it's housing.
That being said - ultimately choice is yours. And it's based on many subjective factors. E.g. you might have bigger ear lopes and some headphones are just not comfortable enough for your longer use, no matter what is the price or the name of the brand. Some people prefer 'in ear' headphones with microphone separated (this can be seen in many, if not all, SC2 tourneys).
I am long time 'audiophile wannabe' (not nearly wealthy enough to purchase what i want) and i do own some mid level equipment of that sort so can tell you from what i've learned and experienced that most of audiophile equipment is not suited for everything. I've seen (and heard!) different rig setups (meaning different amplifiers with different sets of speakers) for listening different types of music. E.g. classical music can sound perfect on one rig, and on the same one some hard/heavy music just does not sound right. To give you a glimpse those rigs were about $20k+. Not to mention that EVERY manufacturer of high quality sound reproduction system has it's own philosophy (from physics/hardware perspective) and as soon as you get close to those high end rigs you might not even notice the difference (apart HUGE price increase). Ofc, you need to take into consideration the type of reproduction media. Don't expect to fully utilize your high end equipment with mp3 reproduction. :-)
Is it worth to buy really nice high quality headphones JUST for playing games? I'd say no. But nobody prevents you to use the same headset to listen your favorite tunes, right? Bottom line is - it comes to your budget and subjective preferences. Just make sure that what you purchase what fits both your budget and personal needs
I use SS Siberia V2 as well. The mic is garbage, but the headphones are incredible and very comfortable. They're roughly the same price on Amazon for mic/micless version and it retracts, so just get the cheaper one.
I'd advise the sharkoon s7 x-tatic 7.1 - i've been using it for about 2 years now, and it is very comfortable, the sound quality is great (d3 actually utilizes the 7.1 surround) and the microphone is detachable and of great input quality.
I also have the siberia v2, white with blue glowing ears. only issue I've found is some programs like league tend to kill my sound drivers if their client is buggy at the time. (for a couple patches, I had to delete and reinstall my drivers for the headset every time I logged onto my computer and decided to play it)
Before you go and spend a ton of money on a headset, I would get your hearing range checked first. The typical human hearing range is 20-20,000Hz, but age and other factors can reduce your range. It makes no sense in buying something like 15-25,000Hz headphones if you can't actually hear the tones.
I wouldn't recommend a razer headset if you do long periods of gaming.
I had a set awhile back, couldn't even wear them because after a few hours it became so uncomfortable. The sound was good, so if your not planning to use it for 3+ hours at a time it might actually be fine.
In terms of what I recommend, Sennheiser has some of the best headsets I've come across, and their pricing is fair.
