Some things are fun, but there are literally no surprises after their marketing job. They show both types of vent. Last, this is an easy item to store for their next visit. They are very vague. I use these for my wireless beats everywhere I go. I only gave 4 stars because the silicone flap that covers the charging port is VERY thin. I know good sound when I hear it, and these definitely live up to their hype. Good:- 90hz screen: Its wonderfully smooth. However, as others have noted there is no way to change the chatback volume or mic mix level. I had bought them ahead of time oh, and they were Christmas gifts for my granddaughter so they were already in another state before it happened.
