Good evening together, do you know reasonable helmet speakers? I have some that you can no longer hear at full volume from 70km/h. I will soon have an onboard MP3 player with steering wheel remote control and 3.5mm jack output. Therefore I don’t want a Bluetooth headset etc. The MP3 player has a 20W amplifier in addition to the headphone output, so I could also take “real” speakers, however, the as flat as possible I want to do without headphones, since I use it to e To hear ambient noises too bad and these disturb me under the helmet. Have at the moment some from eBay for 17,99€, the same as with Polo. Suggestions?
