I definitely wouldnt get on the freeway or above 45 mph with anything important on the roof. So I have heard a lot of sound come out of fairly decent quality speakers. I bought two of these protective cases for mine and my boyfriends pairs of AirPods. no need to break them in. Sound quality is not the top but considering the price, it is excellent. Came with everything I needed to hook it up to my freshly pulled 12v lead. Thats the reason I gave it 4 stars. I figured that the sound quality and comfort would be similar but the open back quality would allow me to talk with others while I played music. Love the overall sound, I was testing these against the Soundcore Life Q30s and the clarity was so much better, a much more balanced sound ( sent the Q30s back). I haven’t worked out in it yet but I know the neophane material is good because i think it’s the same as my sweet sweat belt which I love.
