My A40s eventually became worn out so I did some research, got some opinions, and eventually landed on these.

They are a little outside of your budget but they go on sale every now and then. They are super light - I mean they weight nothing compared to my A40s, but they are durable as hell.

They do indeed work with the Mixamp.

Here are the Game ZERO's (leather)

High-end:

• Sennheiser Game ONE ($169 - mixamp needed)

• Sennheiser Game ZERO ($177 - not sure on mixamp)

• Astro A40s ($250)

Mid-range:

• Playstation Gold Wireless Headset ($90)

Budget:

• Hyper-X Cloud ($80)~~
