The X-Balanced speaker unit's non-circular diaphragm produces more sound pressure, resulting in superior overall sound quality. When paired with a smartphone, the built-in microphone enables individuals to make hands-free calls. Because of Echo Cancellation technology, both individuals can talk at the same time without being cut off, allowing for more natural dialogues. The XE300 supports multipoint technology, which allows two Bluetooth-compatible devices to be connected at the same time and switched between easily. The speaker is waterproof and even salt water resistant, so you won't have any problems using it by the sea or pool, and it's also easy to clean. When fully charged, the XE300 will provide 24 hours of playtime, implying that a single charge should be sufficient to power through any party.
