Product details:

Enjoy your favorite music in private or share it with your friends using these uniquely designed Bluetooth headphones. Like many other over-the-ear designs, these headphones feature a pair of 40 mm drivers, which deliver a 20 Hz - 20 kHz frequency response and 113 dB sensitivity. Where they differ from other designs is that they also sport a pair of speakers using a second pair of 40 mm drivers. Simply flip a switch on the earpiece and the audio signal switches from the drivers inside the ear cup the external ones. No longer will you need to hand your headphones to someone else when you want to share a tune. Just flip the switch and you and everyone else in the room can share the experience
