How comfortable are they? My problem is that I've got a huge head, so a lot of headphones don't fit right (all rear-wraparound sets included). Something like this would be good for cycling or the gym. Bluetooth would be even better.
Is that an inline amp or just a volume control?
Can you wear them for extended periods of time? The reason I ask is for good sound transfer, most of these bone conduction types squeeze your head tightly and end up giving you a headache after a while. Initial comfort apparently doesn't always mean they're comfortable for multi-hour wearing as I understand it.
I wonder if they affect people with fillings, because given the structure of the skull loud vibrations may jar the jaw bone
I can't speak to that. No dental work. Sorry.
You still use these, @mertesn? Or have regular ol' headphones won you back?
