Comfort:I have a big head, so the m40x has quite the clamp. Easy to install with the right tools! Shes my favorite. This company should stop making headsets and start making wireless earmuffs. But great for price! some of the flower petals were a little folded but I was able to steam them flat again. SOME PEOPLE HAVE COMPLAINED that they think that the USB CONNECTION Wire is too short. I hesitated ordering flip flops online because i have narrow feet and the cheap brands are often too wide. Bonne qualités The triple touch does not activate google assistant (not advertised), but it is advertised to activate Siri, which I have not tried.
