Fantastic price for these, RRP usually between $150-$250.
"Always aware eartip" means you can hear your surroundings while still getting really good sound. The Backbeat app allows you to customise the sound and you get good bass with these, certainly enough to enjoy bass heavy music.
They basically sit just outside the ear canal and play music into it. I have these and so far I haven't found anything better. If you ride, run / walk etc these are the best thing out there.
I wouldn't suggest, just because the BT drops out.
