The Xvive U2 guitar wireless system's digital technology delivers incredible audio quality and a super-reliable connection. It also fits in your pocket! The U2 boasts a full 20Hz-20 kHz frequency response, ensuring that you--and your audience--accurately hear the true sound of your instrument. The system has an unnoticeable 6ms of latency, which means that in addition to your tone, your groove will not be affected! The 2.4GHz ISM band offers crystal-clear wireless broadcast, ensuring the integrity of your signal over 70 feet of range onstage without any signal dropouts. The onboard Li-ion batteries help make the U2 wireless system environmentally friendly, and they last up to 5 hours per charge. The chassis is made out of durable ABS plastic that can withstand the rigors of touring and the harshest of climates. If you use effects, not only can this wireless unit run from your guitar / bass to your pedalboard, you can also use a second U2 system to run from your pedalboard to your amp! No more dodging cables on stage!
