Summary: Still shopping for Sennheiser brand despite this experience.
Pros: Connected to Turtle Beach Audio Advantage Micro and sound quality is excellent. Very even response and tonal qualities with music. Did not try with other sources or test the microphone.
Cons: I intended to use the PC161s in my office in combination with the Sennheiser UI760 for music and telephone, but they look so ungainly I cannot imagine being seen wearing them. I asked a coworker to try them on and his response was "no bro' I trust you". The headband is nearly flat across the top ...
Summary: If you are going to buy these you must be using them for one thing and one thing only GAMES. Going to try burning these in seeing if that helps. I have gone through over 10 pc 150 headsets they last me from over 1-3months before a speaker, mic or everything starts going out.
Pros: This headset is too low in volume to distort, i am sure they would sound decent with any high end sound card. i currently have usb sennheiser sound as i have no pci slot. They sound great in-game with decent sound and positioning but for music and movies they blow.
Cons: Volume is too low. Bass has no real punch. Other reviews sucked me in. Maybe they last longer than 150 models? Mic is not that great. NOT FOR MUSIC.
