If you are looking for a pair of noise isolating gaming headphones that are super comfortable (even if you wear glasses), you definitely want to check out the GSP 350 headset Sennheiser gaming series!

The Sennheiser GSP 350 are closed-back and great to wear for long periods of time for a maximum gaming immersion experience.
The Sennheiser GSP 350 surround sound gaming headset has speakers mounted against solid cups so, the sound from the headphones won't get picked up by the microphone when chatting during online gaming.
The broadcast quality, noise cancelling microphone on the Sennheiser GSP 350 filters ambient sound very well and has a well balanced sensitivity (-41 dBV/PA) with a frequency response ranging from 10 Hz to 15,000 Hz. The microphone also has a neat "lift-to-mute" feature that allows you to automatically mute the microphone by raising the boom arm.
The Sennheiser GSP 350 closed back surround sound gaming headset is also low impedance (19 Ohm), which is great as it means you can use this headset on low-power devices.
As far as sound, the Sennheiser GSP 350 closed back produces a deep boomy bass with detailed clarity thanks to the low end 26 kHz frequency response and 15 Hz high end frequency response. Bomb impacts and footsteps in shooter games such as Black Ops 3 really come alive!
A few other nice convenience features you get with the Sennheiser GSP 350 surround sound gaming headset include memory foam ear pads, volume dial, Dolby Surround 7.1, comfortable split headband and surround sound dongle for PC to switch between stereo sound and surround sound.
