Another entry into the portable wireless speaker market is The Blaster by Nixon. Made of durable seamless rubber it’s made to withstand the elements. WithÂ BluetoothÂ® connectivityÂ , auxiliary inputs (comes with the wire) and great acoustics. Â This is a grab it and go to a house-party, skate park, beach, on the go device. Â There are no limits where this device can take you. Â Oh and one of the coolest features around is the integrated microphone for calls. This is something that’s lacking in some of the more popular models.
