Pros: Great gaming sound, Great mic. Best closed back soundstage I have ever heard. Rediculously comfortable, excelent build
Cons: Harsh before burn in, Large condenser mic needs lots of power, fatuiging music listening. Bad pairing with Creative soundcards and SBX pro studio
I made a huge mistake when I got these.... First thing I did was plug them into my phone and try to listen to some music... Bad idea! This is one of those headphones that I wouldn't even listen to until after 50 or so hours of burn in. The sound signature of these is specifically designed for gaming. Before burn in there is a very strong harsh and unpleasant spike in the upper mids. After burn in everything smooths out but there is still an upper mid bias. Why though? For the glory of gaming of course!!! To me these seem to have a fairly close to neutral bass and treble response with a boosted mid response. With no EQ and no virtual surround sound when gaming these aren't the most fun sounding headphones but they are very accurate. The mid spike makes footsteps and enemy movements really pop out at you. I am guessing that was absolutely the intent by Sennheiser when they made these. They are vastly different from the sound signature from most gaming headsets that have loose boomy bass and boosted treble. It takes a while to get used to but after you do you won't ever want to go back if you are looking for detail and want accurate enemy placement. For me where these really come in to their own is when you use virtual surround sound software with them. The 2 I have tried are Creative SBX pro and Razer surround pro. Lots of debate on what is better but for these specifically my vote goes to Razer. The creative software does the same thing as the sound signature from the Game Zero's... It boosts the mids. With that on top of the software boost it just becomes too much and a little harsh. The Razer software doesn't really EQ the sound it just adjusts placement of sounds. That works perfectly for these. The razer software also lets you boost the bass. These respond very well to that and become way more fun with a little added low end. I would rather they be flat and require me to use the surround software to boost the bass than to try to cut it out with a boomy sounding headset. With the razer software you can get a full enveloping surround sound experience with plenty of bass and no harshness. Now on to the mic... The mic on these sounds great... If your sound card can power it up. This mic with my Creative Sound Blaster Z might have been the absolute worst mic and sound card pairing I have ever heard. In fact once I got these my 2 year old SBZ got ripped out of my PC and thrown in a box. I have a Schiit stack now so it was time for it to go anyways as I was just using it for mic in. After researching I found that headsets all use small condenser mics that need power. Sort of like regular condenser mics that require phantom power but on a lesser scale. Usually headsets run on 'line power" between 2 and 9 volts. PC sound cards put out voltage to mics usually in the range of 2-5 volts. Most gaming headsets with tiny microphones are perfectly happy getting 2v and sound fine... However the mic on the Gzeros is a bit bigger and is pretty quiet with 2v going into it. More voltage = more sensitivity with condenser mics. Creative cards appear to only put out about 2V. With my Creative Sound Blaster Z I had to max the mic volume and mic boost to get enough volume from this mic which resulted in tons of white noise. Asus sound cards tend to put out a little more voltage to mics (Around 3V) so I would pick that over a Creative card if you are considering these headphones. I would also steer clear if you have Realtek onboard audio as all the Realtek chipsets I have tested put out about 2.2V. There are a few chipsets out there that put out 4.5V and I would assume that would be ideal for the Gzeros or G1's for that matter. Still trying to find a small USB sound card to use for mic input only that puts out 4.5V to use with the mic on these. So far I haven't been able to confirm voltage for anything other than the ones I have personally tested because that information isn't published by sound card manufacturers.
