I’ve never heard of seen Robersons. I had to search online. Is it the square ones?

I’m personally a huge fan of hex sockets. I’ve had torx bits snap and twist before. Don’t think I have had problems with a hex.

Or the 880 for something in between. I have a few headphones but I use my 770’s the most. Had them for about 10 years and done the cable mod. They are just all round great.
