Normally if something is damaged in transit, the distribution company ( in this case Amazon, ) replaces it, usually for free.
As for quality, as I said I have the PX22, which are very similar to the X12. I have no complaints about audio quality and I've never received complaints about the quality of my voice over chat before. For $40 I think you'd be hard pressed to find a better headset than the X12.
However, these are NOT surround sound headphones. Let me explain ( and if you already know this, please forgive me. ) You either need multiple speaker drivers inside the headset or some way to simulate surround sound through two speakers. The X12 features neither. It is possible some games might synthesize a two-channel audio mix that simulates a surround sound, but if the game is doing that, it means you'll get virtual surround with any headphones. So while the X12 has good audio quality, you're still just getting stereo sound, not surround.
If you want surround, you need some kind of dedicated digital sound processor ( DSP ) that takes a multi-channel audio signal and mixes a virtual sound over two channels. Some USB-only gaming headsets have a DSP that bypasses your motherboard's sound card and mixes a virtual surround soundstage. You can also get standalone DSP's that plug in between your mboard and your headset. But again, these need a multi-channel audio source to work.
Bottom line, if surround sound is important to you, you'll need to spend closer to $100 to get it.
