First, I have the device geladen.Ich did not need the Velcro pads, since the speakers bombig sit on the helmet lining. I have attached the cable to the speakers with small pieces of Velcro on the lining and sewn to the front of the gooseneck of Micros feed. Similarly, the cable of the plug, so that now nothing more slouching unnecessary and interferes at touchdown.
After about 5 hours. I have connected the device. Since I had paired before, I immediately heard music from my EiFon. However, so loud that I winced. Then I tried to reduce the volume, but I did not manage to manual. I then made it on the phone. 0 problemo. In the manual is that some functions in different phones may not work. Sponge 'over it, is not decisive for the war for me.
Then came the call: Everything funzt perfectly!
The sound of the speakers is better than my Inohrkopfhörer from Media Markt (something around 20 bucks). I'm excited. Now I no phone call escapes more and the music sounds better than ever.
By the way I have the base plate additionally secured with double-sided tape, as my helmet where I mounted it, probably thinner than brand helmets. Inside I still squeezed a piece of foam rubber under the clamp. Sits bomenfest!
Conclusion: If you call, and want to hear music and Navianweisungen would be ill advised to buy another device.
Addendum 07.25.2014:
You can adjust the volume but operate via the rotary knob. But not, as it is written in the manual, while pressing the button, but where one quickly, so as not to operate the song changes, left or right turns and stops in this position until the tone is set.
Addendum 07.27.2014:
I forgot to mention that I drive my scooter and Vmax between 45 and 50 kmh is, so that the understanding on the phone is very good. Meanwhile, I have also the rain "test" survived positive.
I repeat my recommendation!
Addendum 08.03.2014:
As before, I give my recommendation. However ....... after I was now a bit longer (3 hrs.) With the scooter on the road, I noticed zuhaus when placing the helmet that both speakers themselves had detached from the velcro. The adhesive with which they were attached, I could rub them off with your finger! Now that is not exactly high quality.
Unfortunately, I must therefore deduct the 5th star.
While I thought about how I could both Velcroringe and the two discs' dranbappen again, it occurred to me that I had made my flight model construction still Velcro® straps. I cut each 4 cm of 3 cm wide strip from, startled the corners to size of the speaker diameter, pasted them then 'it, and put it back into the helmet. So far it holds. Let's see ;-).
In addition, now missing the screw covers the base plate mounting. But it's not so bad. But anyway, I'm a little disappointed. However, does not diminish the basic functions, making calls, listening to music and navigation announcements.
Supplement 22.10.2014
I can not recommend to anyone who calls with helmet and want to listen to music, to buy this product. The price / performance ratio unbeatable. Thus drive every day and am totally / completely satisfied!
