I got this unit to do WebEx and Microsoft Teams conference calls, and having a mute function for those would be great. I was so happy/ impressed with those, for the most part, that I decided to explore other scents in the GBS line-up. Thats 7 more incase I lose one. Doesnt cause razor burn. Unique for a bio-pic film, Michel?le actually provides narration for the film, and even appears at various points in the film to further explain the events. I tried my dads original Airpods and it fit his. I cant believe how comfortable they are! Apparently my ears are big. The case provides about 32 ? 40 hours of additional play time for the earbuds when you?re on the go. These were a great purchase and handled what I wanted them for.
