DryBUDS Free Flows are Waterproof Bluetooth Headphones that link to your music wirelessly so you have total freedom of movement without being tethered to your device or tangled in the cords while working out. The wrap-around behind-the head-design ensures that the earbuds stay in place during intense activity. The DryBUDS Free Flow even feature a built-in waterproof microphone so you can easily make and take calls on the go. ***NOTE*** These headphones are 100% waterproof, BUT bluetooth does not transmit through water. Therefore, these headphones, unlike our other models, will not play underwater.
