Thanks to Dave's advice on the problem with high impedance speakers in my old Autocom headset I was reminded of the custom fit earbuds (that I had made for me at a motorcycle show) which have speakers built in. I previously used these with the TomTom on my Pan via a bluetooth thingy that reposed in a pocket of my riding suit. Sooo.. off to Maplins for an adapter to connect my little earbuds plug to the Din plug on the bike. Easy-peasy thought I, except that the plug on the earbuds is 2.5mm and when buying the adapter I had thought it was 3.5mm - so back I go for another adapter - actually the third because initially I was forced to buy a 5 pin Din to quarter inch, a quarter inch to 3.5mm and now with a 3.5mm to 2.5mm I have something half as long as a fishing rod and just as bendy, to connect the 5 pin Din to my earbuds.
The acid test - switch on the radio, switch from bike speaker to headset - nothing! Ah well, perhaps these are high impedance too? But then I thought that the miniscule bluetooth adapter had so little power, surely these earbuds must be low impedance? So it proved when I fiddled about with my national exhibition of adapters and was suddenly deafened by the Kaiser Chiefs (I must get around to programming Radio Three :) ).
Trouble is that apart from the bendy connection, the wire to the earbuds is as thin as dental floss and probably not a lot stronger, so I really still need to find a more robust solution. Well, the OEM Honda headset is one possibility at £200! So too is a variety of cheaper headsets that all promise zero noise, quadrophonic sound and "I'll still love you in the morning". However, the helmet man at Dobles, tells me that my favoured helmet (a BMW flip-up is - despite having big cut outs for the ears - the worst imaginable for installing a headset as there is nowhere for the wires to go. He demonstrated by taking a new Arai off the shelf and showing me how in about five minutes one could install a set in that versus the 3 hours estimated for my BMW helmet. I really don't want to buy another helmet. I still own more than most mortals and not just the ones I have crashed in either, however, it's starting to look inevitable.
I am now looking at the Autocom Pro AVI stuff in the belief that I should be able to integrate it into my Goldwing audio and potentially use it for Bike to Bike communication when I get around to attending Treffens etc.
The man at Dobles is looking into this for me - I hope to hear next week what he finds out. Stay tuned!
