I need to use speakerphone for all my phone calls, I have tinnitus, also can't hear using earbuds. Because I need speakerphone is the exact reason I never answer the phone on a bus, I find it a pain in the a*se I need to use it, i don't want to be a pain in the arse to everyone around me, nobody needs or wants to hear me and my husband talking about what we need from Tesco or what my blood test results are or whatever other crap, just wait till you're off the bus or send a text ffs
