Take your tunes on the go with the Sony SRSXB2RED Portable Bluetooth Wireless Speaker in red. This speaker's two 1.65" full-range drivers and passive radiator are tuned for dance music and can pump out music for up to 12 hours on a charge. EXTRA BASS mode enhances low-frequency tones for deeper, punchier sound. The SRS-XB2 is water resistant and connects to your device via Bluetooth along with NFC for one-touch pairing, or via the 3.5mm AUX port. Two speakers can be linked together for additional coverage.
