Best headset I've ever owned.
I've had most recently Sony, Sennheiser and Bowers & Wilkins flagship models.
The Shure Sonic 50 unit is far more balanced in sound, appropriately weighted, sturdy, and fits my egregiously large ears comfortably without feeling like putting my head in a vice. Can wear for hours comfortably. Dual BT connection is a plus. I can have the laptop and phone connected simultaneously to answer calls, automatically pause the laptop, then automatically resume playback when the call ends.
Only con I've experienced is while wearing a hat I came to max out the headband adjustment. One more increment of adj. length would be nice, but not critical.
