When I first started working remotely, I made the mistake buying a cheap pair of headphones. The consequences were unreliable conference calls with a mandatory "can you hear me?" introduction in place of salutation.
No More! This affordable Sennheiser gaming headset I picked up the other day has been working great: https://amzn.to/2pxABnQ
All of my conference calls have been crystal clear, and I honestly don't know whether a better value can be had. What types of headsets are other remote folks using? This is becoming somewhat of an obsession for me!
I'm mostly working from home, public library and coffee shops with my Macbook. I've never tried a laptop stand, but I'm now thinking about getting one.
Are you using a laptop stand when working? Roost Stand is probably a good pick?
