Should it work with a portable speaker? I tried with several without success. Sometimes seems to work but most of the time I get noise. Seems like a connection (groud) issue, but I have no idea how to solve it. Cable is a 3.5mm 3 pole jack. It works great with a headset.Question by: admin on 2018-12-18 02:21:35
Hello, I mean something like Sony SRS-X11, bluetooth speakers that can be also used by connecting a jack 2.5mm. Regards!Answer by: admin on 2018-12-18 02:21:35
