>>1336177I picked up a pair of the newer version (Aftershokz Air) a month ago and absolutely love them. They're not like normal headphones/earphones which block your hearing so you can still hear outside noise perfectly fine. Sound quality and maximum volume are a little lacking but not inadequate. There's a button you can use to play/pause/skip or talk to your google/apple assistant which is super sweet.
I wear them everyday, whether I'm riding or not. It's like having background music playing all the time. They work great for audiobooks and podcasts too. And yes, I'm fairly sure you can connect more than one device at a time with bluetooth. You can multipair this headset to two devices to seamlessly jump between audio sources as well.
The microphone is pretty shit though, google assistant and whoever you're talking to will have a hard time hearing you in noisier environments (read: while riding)
It was just weird the first few days because it was the first time I've ever experienced bone conduction technology and having music beamed directly inside my head was a completely new experience.
