So finally, I plug the S-500 in and check them out.
They are very comfortable when you put them on, and are still comfortable an hour later. I see no reason why they would get uncomfortable during an all-nighter.
I started out listening to music. I immediately noticed the clarity, as good as any good studio headphones I have used and actually much better than the ones I have. They are very responsive throughout the sonic range, they probably have more bass response than any stereo headphones I have used.
I spent some time playing around with the very good 10 band equalizer on my sound card's software. Every band is clean and clear, even the 16kHz band, which I usually can't hear.
Of course, gaming is what they are for, and gaming is what I will do. I spent several hours playing Oblivion, Battlefield 2, Battlefield 2142, America's Army and Call of Duty 2. As with music, the S-500 has excellent sound, maybe too good... I'm not really accustomed to hearing everything so well.
And after about five hours, they were still comfortable.
The Everglide S-500 Professional Gaming Headphones have an excellent sound, comparable to studio headphones costing much more. They are very comfortable, they seem durable and come with a carrying bag. I'm still not sure about the lapel-styled microphone, but for around ten bucks, you can pick up a desktop mic. The S-500 runs around $90 USD.
And the S-500 earns the OCIA.net Seal of Approval.
Thanks Everglide for supplying this review item.
