I'd like to stream music from my phone to the audio tuneups (basically headphones) in my ski helmet. The tuneups have a 3.5 mm female jack. I was wondering if a product existed that's Bluetooth compatible and would stream music *out* a male 3.5 mm jack that I could then plug into my helmet.
I'm trying to avoid directly connecting my phone and helmet. I've had problems on an old phone where the connection gets knocked around in my pocket (and skiing can get bumpy) and it ends up breaking the entire audio jack on my phone. That causes the sound to drop out of one ear (permanently) if I don't hold the cord just right.
Second, there are Bluetooth audio tuneups that would make this alot easier to do directly. Unfortunately they cost $200 bills, and I'd need to get a new helmet for another $130 or so... So I'm hoping to avoid that...
I have one made by Logitech. The sound quality is awesome - better than a headphone extension cable from my iPhone. I did not compare it to a dock with speakers.
Bad news for your application is that it is rather bulky and uses a power adaptor for electricity. You would have to rig up a battery system for it. I believe it is larger than the ones you listed; and I remember reading about one that is both small and battery operated.
You might also want to look at the Sony MW600. It is a bluetooth headphone device, but the the ear buds are attached via standard mini jack, so the reciever can be hooked to other devices or other earphones. It is very small, great battery life, with usb micro charge port, and has built in FM radio. Sound quality and sound level is good.
