The covers also add some bulk so using the original case for the AirPods Max can compress the ear pads. Theres a silver button on the left ear-pad (theres an "L" and "R" inscribed faintly on the adjustment piece above each ear-pad), and you have to press and "hold down" the button until a voice tells you the earphones are connected. Its a shame, really, cause I was truly looking forward to this purchase. Pros:- Material is excellent, comfortable for long or bumpy rides, built for durability and extreme weather- Lives up to the Thule reputation- Package arrived intact and very well packagedCons:- Too small for my 4 y/o at his 42" height, leaving little room to growOther observations: While not necessarily an issue with this particular Thule seat, my toddler falls asleep during rides (as many do) and there is some risk of sleeping toddlers in this style of seat straining their necks while falling asleep. Youre spending $1000 on earphones. I want them to be realistic. Fits my 2019 Jeep Grand Cherokee perfect! This is the main reason I wanted a switch. Natürlich kann man echtes Leder nicht mit Birkoflor vergleichen. However the sound quality is far better but with hindsight I should have gone for an over ear pair for better comfort.
