if i were you, id pay the extra and get the USB sets, far better than the amplifier set (ive owned both)
Amplifier set Pro`s:
no team speak corruption (will explain further in)
can use on your DVD player if it outputs 5.1 sound.
Cons:
amplifier picks up every frigging taxi and mobile phone within half a blooming mile.
its very distracting to hear a taxi driver halfway through BF2 ...
speakers are difficult to level out
right bass driver on these model has a tendancy to blow then distort (i went through 3 sets via RMA)
Analogue controlls
no microphone mute on the controlls
too many damn wires and too much of it, youve got the 3 audio connectors at 2 meters, the main headset wire at a good 14 feet, the mic wire that splits off that adding another 6 feet, the power adapter for the amplifier, all in all makes for a mess which makes it difficult to look after (i cant count the ammount of times i got the wires wrapped in my office chair wheels)
the mini amp can give out waaaaaay more than the headset can take, leading to a lot of blown headsets.
USB set Pro`s:
much shorter wire!!!
got about 8 feet here.
only 1 thing to plug in to the system
no interfearence from taxi`s, aircraft, carrier pigeons with walkie talkies ect ect
nice digital controlls with a mute button for the mic
speakers are always configured for optimal 5.1 surround sound
USB soundcard built into the digital remote
no base driver pop issues
comes with a hook to put your headset on when your not using them
Cons:
ts corruption...
very rarely, your ts craps out on you when you launch battlefield 2, i.e. your mic gives mad feedback, but its easily fixed by turning off ts and restarting it, ive had this headset for a month now and its happened twice (i use it every night)
cant use on your DVD player as its only got a USB connector for your pc.
