Buy iems for 5usd and enjoy skull-shaking lows, someone recommended them for bassheads in the iems thread

Thanks To.M but I kinda don't like in-ear ones. I know that they have better Bass and sound quality. However, if there is any open back iem which does not create vacuum issue, I might consider. I guess Beoplay B3 is one of them but it is $150.
