There are small metal plates on the side of the unit, giving it even more presence overall. Still a little tight fir me in my last month of pregnancy but theyll be great afterwards! The firmware update just shut down and disconnected the keyboard each time and the video reviews on YouTube showed only what I was missing. 98 and just about 3 weeks ago. I bought these in a 7. The sound quality of this headset is very good. Waited until retiring them to write this review. I am so happy I bought them! They have a velcro adjustable top strap, lined with a soft material, to get a perfect fit for a wide variety of foot widths. Go ahead and buy it you wont be dissapointed!
