What makes the Pulse unique is two things:
-The "Bass Impact" which apparently makes the headset vibrate
-An included audio jack cable thing to use the headset on you Vita, music player, etc...
From what I've heard, there's no improvement in sound quality over the originals, and they have proven to also be a bit more flimsy. I've had the original for a year-and-a-half now, and I couldn't be happier. They work great, good quality, without paying the premium for a handful of gimmicks.
Get the Elite. Read the reviews on Amazon for both headsets. Pulase has plenty of complaints, butPulse Elite is being raved about consistently. I'm actually buying a Pulse Elite next week thanks to those incredible reviews on Amazon.
I have the Pulse. The Bass Impact is pretty cool with music (thanks to the fact that this version allows for your other devices). If you plan on using them for music too, get the Pulse.
