Simply load all your favourite music into a Micro SD card, plug it into the headphone and you're good to go for 12 hours. No need to worry about cables or DAP, just grab the headphones and go !
I've been enjoying these for the last couple of days and thought I'll share this find with you guys who hate having to deal with messy cables and/or easy to lose DAPs, I've also discovered that NIA makes a version that connects via bluetooth ver:2
Whacky find! Thanks for sharing. I look forward to more impressions about them as time goes on.
