The logitech just sounds better. It has even more volume in the sound than the K702.
The thing about sounding crap was just before I got the amp. With the amp they sound good. But I like the sound of the G430 gaming headset more.
Not for gaming but for music. I rarely game in the last months
G403 and other gaming headsets have very high sensitivity (efficiency) since they're designed to work with even just a limited current/voltage USB soundcard that usually comes with them.
Anything that can go louder easily can tend to sound "better" to most people the same way recording companies are waging a Loudness War in quashing dynamic range. Louder easily sounds better because you hear everything, never mind even if the recordings have quashed dynamic range in the case of modern mastering standards.
A lot of other factors come in here as well. For a start, helping out efficiency is isolation. The G430 is closed back, on top of which its response below 50hz is better. Louder sounds better already and then it sounds fuller because you have less interference - in terms of distortion and ambient noise - vs the bass. The K702 has lower sensitivity and open back earcups. Just the cooling system on a gaming rig will get in the way of that, which is why I don't even use my HD600 on my gaming rig nor use that as a source for listening to music. Even at idle I have two 16dB intake fans and a 12dB fan that's blowing against a waffle grill on the exhaust (ie the max dB rating on the fan means nothing for exhaust port or radiator use).
On top of that the AKGs have a self adjusting headband that tends to fit too loose on some heads, further affecting lower frequencies as it can't use the earpads to create a seal. Even if you're driving the K702 with a Burson Conductor that won't get around that problem.
"Soundstage" Whats that? I dont notice that in ANY way.
Studio headphones are useless
Most likely the music you listen to doesn't even have any soundstage to be imaged to begin with. On other recordings you're supposed to hear the vocals clearly ahead of the other instruments dead center, which is easy enough to do. What the K702 does is image it like this will be at your forehead if not outside your head. And then where in other headphones the percussion will be clearly behind that the K702 images the drums far behind that, with drums moved to the center (unlike how people love the aggressive in your face splash of cymbals on Grados, which if you shrink a band down to scale to teh size of your head, puts the cymbals at the ears - that's like having action figures playing the music but Mr. Fantastic is showing off his stretchy hands for the cymbals).
This adds another problem for why people who like anything as different from the K702 as possible: imaging everything else farther out from the listener, particularly the percussion including the bass drum, as well as the bass guitar, makes it sound relatively weak. It's even farther from a chest thumping bass drum like with ACDC and Def Lepard than any other headphone, and headphones unlike speakers have to make that compromise. On proper speakers in a properly dampened room the bass drum will sound like it's coming from waaaaay behind the vocals, but you don't give up the chest thump senstation since the speakers fill the room with soundwaves regardless of how they image. So as long as they have a strong enough low end you'll get that. With headphones it's a compromise between head-thumping bass whether it's Grado's upper bass or total bass boost on bass headphones, or a deep soundstage.
Again though if none of that make sense to you the K702 is definitely not the headphones for you. It's for people who need to use a headphone but really would much rather use speakers, except they can't (shared walls, sleeping babies, etc).
Lol im so depressed right now.

I wasted so much money.... I want my money back so damn hard now.
"Gaming headsets all sound crap" Yeah *** the people who are saying that.
"Soundstage" Whats that? I dont notice that in ANY way.

I'm mad
This is why if I don't get the vibe that somebody has some background in speaker audio I try to sway them away from AKGs and just go with Grado.
