Ok you need surround sound for gaming, it's just better. Either you get true 5.1 with multiples speaker headphones, or do virtual surround sound. True surround headsets are limited to gaming headsets and fairly low quality so I recommend virtual surround sound.
To get virtual surround sound you need a USB headset or a sound card/on board sound with either Creative or Dolby Headphone. If you use an external USB DAC you need software such as Razer Surround to get virtual surround sound.
Here is a breakdown of what's available:
- Seinheiser GameOne and PC350 - Both are analogue and require a sound card or onboard sound. GameOne is also for Xbox and PS4.
- Seinheiser PC636D - Includes a USB soundcard so you don't need a soundcard
- AKG HSD 171 and HSD 272 - both analogue but this is a professional dynamic microphone with XLR plug. You need to convert to 3.5mm to use on a PC if you don't have a USB audio interface mixer.
Both the Seinheiser and AKG are professional products and great microphones. The seinheiser is more geared for gaming hense the 3.5mm microphone cable. The AKG is more professional and designed for broadcast.
If you don't have a soundcard or good onboard sound then the Seinheisser PC 636D would be ideal.
Now if you don't want the microphone attached to the headphones, then a regular pair of headphones are required. I recommend the following.
AKG K240 MKII - Semi open backs, removable cable, velour ear cups included, affordable.
AKG K271 MKII - A step up from the K240, closed backs
Seinheisser HD380 Pro - Closed backs
Grado SR225e - Awesome headphones, open back. If you prefer closed back the AKG or seinheisser are required.
For a microphone I recommend a modmic to clip on which is 3.5mm analogue and noise cancelling requiring the sound card. If you prefer a desk mount mic the Samson C01U USB mic with it's matching shockmount is recommended. The Blue Snowball and shockmount is also good but I prefer the Samson. You can get better mics like the Yeti but they have different selectable pickup patterns that are not required for straight ahead PC voice chat. They are more for instruments, or 2 way one person on each site interview style chats, etc...
With the Samson or Snowball I would also pick up a deskmount or wallmount microphone boom arm. This gets the microphone off the desk where it'll pick up the keyboard clicking. Then you can position it in front of your mouth like a headset and swing it out of the way when not in use.
If you don't have a soundcard, then an external USB DAC can be used. I like the M-Audio super dac. It allows you to plug headphones and speakers or home theatre and switch between the 2. It also has an aux input for a cellphone. I like DACs because of their sound quality. Secondly they don't require drivers and software like a soundcard so they always work flawlessly. They just use generic built in windows drivers like how a USB stick just works when you plug it in. So a DAC can last 10+ years and just work on any future version of windows without requiring support from the manufacturer. I hate how I've gone through 2-3 high end soundcards over the years because Creative and Auzentech stopped supporting them and the drivers where buggy. Also owning a DAC means no expensive motherboards are required just to get the good onboard sound. If you live in the USA the emotiva DACs are very good.
So in conclusion:
- If you just want simple plug and play then a USB headset is nice. The Seinheiser is a good one.
- If you have the soundcard or good onboard sound and again want a simple headset my preference is the AKG HSD271. I'd convert the XLR to 3.5mm for the microphone. If you don't want to bother the Seinheiser GamerOne or PC250 are good.
- If you want the seperate micrphone my favorite headohones are the AKG K271 MKII. The Grados are also great but harder to find or require a purchase direct from manufacturer. The Grados are open back and the AKG are closed back so it's an easy decision based on which you prefer.
- For the microphone if you don't mind it attached the modmic is excellent. If you prefer separate then I recommend the Samson with the shockmount, pop filter, and a boom/arm.
- If you have a sound card/on board sound then you can use that now. But I like the simplicity and sound quality of a USB DAC. Razer Surround allows you to still get virtual surround sound through headphones. I also prefer the separate desk microphone so my earphones are free for music, movies, tv, guitar, etc... Also having real headphones means they are repairable and will last a lifetime. Both AKG and Seinheiser offer replacement parts and the entire headphone or headset can be repaired.
