The only difference is the price and that a50s are wireless. I would definately get a40s they are probably the best headset you can get.

I think you should go with the wired ones. Even though I hate cables, It sure offers a better sound quality and performance that other headsets can't even match.

For just game audio I would recommend the A40's because they are cheaper, but the A50's look beast.

A40's for sure mate! They are amazing

If I had the money I'd take the A50's anyday!

i would say a40, the are cheaper and will be just as good

I read a lot of negative reviews comparing the A40s to the A50s which claimed that the A50s are lackluster compared to the A40s in numerous ways. I almost ruled out getting them, despite the fact that I was terribly in need of a wireless headset. I am here to say that as a longtime A40 owner, I adore the A50s and think they deliver in all respects. It's the same quality experience Astro A40 fans are accustomed to but in a highly portable package that eliminates my only complaint with the A40s... the abundance of wires.

I have the a40's, my friend has the a50's. We both swapped the headsets at one point to see which one was better. Me and my friend thought the a40's were better. I mean don't get me wrong the sound quality is great on the a50's but it just feels like it's lacking something. Right now, I would say it's your choice. If it's your first time buying one of these type of headsets, don't worry about it. Over time you will fall in love with it. Don't mind the wires, they are not annoying at all. They really never get tangled, plus they always stay in one place.
- Have had my a40's for about a year and a half now, and nothing has messed up.

Wired > Wireless

Wireless might be more convenient but the wired version will last longer.

It depends on whether you want a wired or wireless headsets.

Personally, I would get wired because I hate going through the hassle of constantly having to deal with batteries and charging stuff.
