Bluetooth earphones/speakers cuts of first 2 seconds off songs.

On all my devices i have found that when i play my MP3 music with bluetooth earphones or speakers, it cuts off the first 1 or 2 seconds of the song. it seems to fade in. Especially when songs on an album sync into each other (like for example a Pink Floyd album) it abruptly cuts off then the next track fades in ruining the flow of the album. I have wire earphones that i can connect to my ipad and mac but not my iphone because there’s no earphone jack. It does not cut out between songs. Only the bluetooth earphones do that. My sister wants to get me special bluetooth earphones that won’t do that but honestly i have doubts about that. What would be your answer?
