Well I am not judging Tom one way or the other but I have been through numerous pc headsets in my day and the Sennheiser PC 155s I had were the best, bar none, period. Amazing sound, and the best mic of any out there. I mean perfect clarity it was just amazing.
But like the person said above the cords are weak. Its honestly the stupidest thing I have ever seen. You take a headset and create it to the highest quality possible then you put a dinky ass cord on it. Mine broke, just by slightly pulling it out. It was not forced, it was just that weak. I would love to of kept em for the sound but considering how easily the cord broke once, I was very weary of trying it again.
I am still thinking about picking up another set, but I was hoping they would fix the HUGE issue first. And it is a huge issue, I mean this thing litterally broke by putting normal strength against it to pull the cord out, the one I had really was that weak. So if you get them make sure they are not where anyone can bump them, and make sure the cord does not get hung on anything and get pulled too hard or you will have a very nice headphones set without a way to connect them.
Oh and mine broke right above the connector.
