Question: Real or virtual 7.1?
Document: I've been researching about the Sennheiser PC 360 and the Astro A40 because they have what I want from a headset. The most value in a headset. The only thing Astro A40s had over the PC 360 was the usb virtual 7.1 surround device which on its own was quite expensive.
I currently have the Sennheiser PC360 headset that I've been gaming with for over a year. So I'm quite familiar with this excellent headset. In fact, they are nearly identical. The 363 has a vented covering instead of wire mesh on the outer ear piece and the mic grill is orange. That's about it. The big piece that you're paying for here is the USB sound card that creates a virtual 7.1 surround environment with Dolby Digital.
This is a great headset, and beautiful designAnd also comfortableThe sound is clear, and good 7.1 surround sound
Nice sound quality.The USB soundcard works with the PS4, but you can only get stereo sound.Looking for a workaround so I can get 5.1 or 7.1.
Great audio in stereo mode. OK audio in 7.1 surround mode. It sounds like your in a tunnel. Tends to clamp to my head a bit hard.
Best sounding headphones ever, especially when 7.1 is switched on, sounds like its inside my head. Cant find any cons on these babies but maybe price.
These headphones are a bit expensive, but awesome. If you're looking for a higher-end surround sound gaming headset then this might be the product for you. Here's a quick breakdown.PROS:- 7.1 surround sound is awesome! I'm not a super audiophile, but it sounds excellent to me.- Comfortable.
I almost didn't get these because of the price. I'm glad I did, these are the best I've ever owned, (upgraded from logitech's 7.1 wireless leather headset)The ProsFeel+When I put them on, I noticed they are extremely comfortable. The cushioning is a bit more firm then other headsets, and these are a lightweight model.
Overall, it did provide a nice environment for fps game, but its musical quality just not as I expected, and it feels comfortable while your are wearing it but not recommended if you are living at a hot place. And the customization of sound is kinda bad because you can only change the option of 5.1 or 7.1 only, you can not adjust the equalizer once you plug it with the sound card.
This was tested with games, such as Crysis 3 and FarCry 3. Personally I prefer quality stereo audio, but if 7.1 is your thing, you're gonna enjoy it using this headset. (In case you didn't know, the 363D headset is based on the audiophile quality HD 518 headphones).Thanks for reading this review. Hope it helps.
