I use Team Speak and this set works GREAT! mic is in a good place, team mates tell me i they can hear me much better now (is that a good thing?), head phones sound great! i would recomend these to ANYONE doing any kind of online gaming in use with any team chat software.
GREAT PURCHASE for under $20... retail website has these for $40

I purchased these headphones at the national retail chain for $40.00. I feel like a chump for neglecting to check out Amazon first. Headphones are satisfactory. They fit very comfortably, but I can see how a person with a small-to-medium sized head could be annoyed by them. The headset is very wide. The cups would tend to tilt in at an awkward angle on a person with a small/narrow head. Excellent buy at Amazon's low, low price.

The headset is great except for one thing. I'd would totally agree with the guy that said the microphone cord sucks. I've been through 4 sets of these headphones. Everytime the mic has stopped working on each set. Drives me nuts! The headsets only get picked up from the desk, put on my head, and then back down to the desk. Not even heavy use... and they break. I contacted Altec Lansing and their reprsentative said that they do indeed have multiple reported problems with the mics going out. They said they will replace the headphones, but I will be without them for 4 weeks. Sucks! Look at another set of headphones if you'd like them to work longer.

Do not lisen to the reviews below I have had this headset for over 5 months and so far it has been smooth selling. Yes when you first get them your ears do get quit hot and the headset may be abit uncomfortable at first. But after a few days that is completly gone. They are the most comfortable thing I have ever worn they are padded like crazy. The ear pads are thick and give a very good amount of noise reduction. There is even a pad ontop were it would make contact with your head.

My primary purpose for getting this headset was for gaming. When I originally bought this pair about a year ago, I paid almost twice as much at Best Buy, which is completely ludicrous for the kind of product this turned out to be. For around $20, it might be an okay value, but I would recommend you look around some more, in case you feel like settling on this.

So here's what I thought about the AHS-502...

SOUND:
I got suckered in by the neat look and packaging of the AHS-502, but don't let its sleek silver appearance or the fact they're calling themselves a "Studio Headset" get your hopes up too much. The sound, overall, is pretty mediocre. Nothing terribly bad, but pretty lackluster. They're adequate for gaming and not so great for music.

MIC:
The microphone tends to pick up a fair amount of ambient noise, so watch out where your fans are pointed.

CONSTRUCTION:
The headphones are actually quite sturdy. The same goes for the microphone boom. I've moved the boom thousands of times and it's still attached to my headset with no sign of wear. I've trashed my fair share of headphones, and this one has stayed in one piece.

HOWEVER.... the wires are another matter. The only place I used this pair of headphones was strictly for PC gaming, so it pretty much stayed in one place all the time. Given that, the wear on the wires shouldn't have been that extreme, but within about half a year I started having problems with the microphone. It seems that part of the cord near the little volume control pod seems to have broken or lost contact so it wasn't passing my mic signal through. I would have to fidget with the wire in order to get my mic working again. Eventually, my microphone boom became a useless prop.

COMFORT:
Overall, these weren't too comfortable. They would be okay for short periods of time, but they're definitely not meant to be worn for extended periods of time. I was typically ready for a break after about an hour. Given the lackluster sound, they should have gone for a lighter physical design. And since my primary purpose was for gaming, the lack of comfort was pretty disappointing.

FEATURES:
The cord has an attached control pod which includes a volume wheel and a 3-position switch for the microphone input volume (low, high, off).


PROS:
1) sturdy headset & microphone boom
2) decent value for around $20, but no more than that

CONS:
1) flimsy wires killed my mic
2) mediocre sound
3) fair amount of ambient noise via the mic
4) uncomfortable within short period of time

If the microphone didn't crap out on me, I might have been a bit more forgiving, but that was my final straw with an already mediocre, over-priced headset. Maybe you'll have better luck with your cord, and the price here at Amazon is definitely better than the price I paid for it, but I would definitely recommend looking around further.

Personally, I just picked up a pair of Sennheiser PC150s to see what all the fuss is about and I'm fairly happy with them so far. I'll probably post a full review on them in a bit, once I've had more time to evaluate them.
