Plantronics C520 headset

Plantronics Blackwire C520

I’ve always been a fan of Sennheiser. I have a Sennheiser HD 218 because its on-ear and not too big.
But on my work, I’m constantly switching between a headphone and a headset for using Skype or Google Hangouts.
Time to find a headset that delivers the Sennheiser sound with a microphone for conferencing.

After an intense search I found the Plantronics C520.
