BlueBuds X not only delivers what you would expect from headphones of this caliber, but also packs some really nice surprises as well. BlueBuds X rewrites the rules of Bluetooth audio, delivering a sound you have never heard before. BlueBuds X are the smallest Bluetooth headphones available, yet they pack an incredible 8 hours of play time, double that which has previously been possible from a product this small. Enjoy a full day of music and calls, or work out an hour a day for an entire week on a single charge.
